Responses of sympathetic outflow to skin during caloric stimulation in humans. (1/477)

We previously showed that caloric vestibular stimulation elicits increases in sympathetic outflow to muscle (MSNA) in humans. The present study was conducted to determine the effect of this stimulation on sympathetic outflow to skin (SSNA). The SSNA in the tibial and peroneal nerves and nystagmus was recorded in nine subjects when the external meatus was irrigated with 50 ml of cold (10 degrees C) or warm (44 degrees C) water. During nystagmus, the SSNA in tibial and peroneal nerves decreased to 50 +/- 4% (with baseline value set as 100%) and 61 +/- 4%, respectively. The degree of SSNA suppression in both nerves was proportional to the maximum slow-phase velocity of nystagmus. After nystagmus, the SSNA increased to 166 +/- 7 and 168 +/- 6%, respectively, and the degree of motion sickness symptoms was correlated with this SSNA increase. These results suggest that the SSNA response differs from the MSNA response during caloric vestibular stimulation and that the SSNA response elicited in the initial period of caloric vestibular stimulation is different from that observed during the period of motion sickness symptoms.  (+info)

Epidermal growth factor receptor relocalization and kinase activity are necessary for directional migration of keratinocytes in DC electric fields. (2/477)

Human keratinocytes migrate towards the negative pole in DC electric fields of physiological strength. This directional migration is promoted by epidermal growth factor (EGF). To investigate how EGF and its receptor (EGFR) regulate this directionality, we first examined the effect of protein tyrosine kinase inhibitors, including PD158780, a specific inhibitor for EGFR, on this response. At low concentrations, PD158780 inhibited keratinocyte migration directionality, but not the rate of migration; at higher concentrations, it reduced the migration rate as well. The less specific inhibitors, genistein, lavendustin A and tyrphostin B46, reduced the migration rate, but did not affect migration directionality. These data suggest that inhibition of EGFR kinase activity alone reduces directed motility, and inhibition of multiple tyrosine kinases, including EGFR, reduces the cell migration rate. EGFR redistribution also correlates with directional migration. EGFR concentrated on the cathodal face of the cell as early as 5 minutes after exposure to electric fields. PD158780 abolished EGFR localization to the cathodal face. These data suggest that EGFR kinase activity and redistribution in the plasma membrane are required for the directional migration of keratinocytes in DC electric fields. This study provides the first insights into the mechanisms of directed cell migration in electric fields.  (+info)

Different contributions of the human amygdala and ventromedial prefrontal cortex to decision-making. (3/477)

The somatic marker hypothesis proposes that decision-making is a process that depends on emotion. Studies have shown that damage of the ventromedial prefrontal (VMF) cortex precludes the ability to use somatic (emotional) signals that are necessary for guiding decisions in the advantageous direction. However, given the role of the amygdala in emotional processing, we asked whether amygdala damage also would interfere with decision-making. Furthermore, we asked whether there might be a difference between the roles that the amygdala and VMF cortex play in decision-making. To address these two questions, we studied a group of patients with bilateral amygdala, but not VMF, damage and a group of patients with bilateral VMF, but not amygdala, damage. We used the "gambling task" to measure decision-making performance and electrodermal activity (skin conductance responses, SCR) as an index of somatic state activation. All patients, those with amygdala damage as well as those with VMF damage, were (1) impaired on the gambling task and (2) unable to develop anticipatory SCRs while they pondered risky choices. However, VMF patients were able to generate SCRs when they received a reward or a punishment (play money), whereas amygdala patients failed to do so. In a Pavlovian conditioning experiment the VMF patients acquired a conditioned SCR to visual stimuli paired with an aversive loud sound, whereas amygdala patients failed to do so. The results suggest that amygdala damage is associated with impairment in decision-making and that the roles played by the amygdala and VMF in decision-making are different.  (+info)

High thoracic epidural anesthesia does not inhibit sympathetic nerve activity in the lower extremities. (4/477)

BACKGROUND: Sympathetic nerve activity was recorded in the leg during high thoracic epidural anesthesia with a segmental sensory blockade of the upper thoracic dermatomes to test the hypothesis that the sympathetic blockade accompanying thoracic epidural anesthesia includes caudal parts of the sympathetic nervous system. METHODS: Experiments were performed on 10 patients scheduled for thoracotomy. An epidural catheter was inserted at the T3-T4 or T4-T5 interspace. In the main protocol (seven patients), blood pressure, heart rate, and skin temperature (big toe, thumb) were continuously monitored, and multiunit postganglionic sympathetic nerve activity was recorded with a tungsten microelectrode in a muscle-innervating fascicle of the peroneal nerve. After baseline data collection, muscle sympathetic nerve activity was recorded for an additional 45-min period after epidural injection of 4-6 ml bupivacaine, 5 mg/ml. In an additional three patients, the effects of thoracic epidural anesthesia on skin-innervating sympathetic nerve activity were qualitatively assessed. RESULTS: Activation of thoracic epidural anesthesia caused no significant changes in peroneal muscle sympathetic nerve activity (n = 7), blood pressure, or heart rate. Skin temperature increased significantly in the hand 15 min after activation of the blockade, from 32.7 +/- 2.4 degrees C to 34.4 +/- 1.5 degrees C (mean +/- SD), whereas no changes were observed in foot temperature. The sensory blockade extended from T1 (C4-T2) to T8 (T6-T11). CONCLUSIONS: A high thoracic epidural anesthesia with adequate sensory blockade of upper thoracic dermatomes may be achieved without blockade of caudal parts of the sympathetic nervous system. This finding differs from that of earlier studies that used indirect methods to evaluate changes in sympathetic nerve activity.  (+info)

Amygdala-hippocampal involvement in human aversive trace conditioning revealed through event-related functional magnetic resonance imaging. (5/477)

Previous functional neuroimaging studies have characterized brain systems mediating associative learning using classical delay conditioning paradigms. In the present study, we used event-related functional magnetic resonance imaging to characterize neuronal responses mediating aversive trace conditioning. During conditioning, neutral auditory tones were paired with an aversive sound [unconditioned stimulus (US)]. We compared neuronal responses evoked by conditioned (CS+) and nonconditioned (CS-) stimuli in which a 50% pairing of CS+ and the US enabled us to limit our analysis to responses evoked by the CS+ alone. Differential responses (CS+ vs CS-), related to conditioning, were observed in anterior cingulate and anterior insula, regions previously implicated in delay fear conditioning. Differential responses were also observed in the amygdala and hippocampus that were best characterized with a time x stimulus interaction, indicating rapid adaptation of CS+-specific responses in medial temporal lobe. These results are strikingly similar to those obtained with a previous delay conditioning experiment and are in accord with a preferential role for medial temporal lobe structures during the early phase of conditioning. However, an additional activation of anterior hippocampus in the present experiment supports a view that its role in trace conditioning is to maintain a memory trace between the offset of the CS+ and the delayed onset of the US to enable associative learning in trace conditioning.  (+info)

Neural activity relating to generation and representation of galvanic skin conductance responses: a functional magnetic resonance imaging study. (6/477)

Central feedback of peripheral states of arousal influences motivational behavior and decision making. The sympathetic skin conductance response (SCR) is one index of autonomic arousal. The precise functional neuroanatomy underlying generation and representation of SCR during motivational behavior is undetermined, although it is impaired by discrete brain lesions to ventromedial prefrontal cortex, anterior cingulate, and parietal lobe. We used functional magnetic resonance imaging to study brain activity associated with spontaneous fluctuations in amplitude of SCR, and activity corresponding to generation and afferent representation of discrete SCR events. Regions that covaried with increased SCR included right orbitofrontal cortex, right anterior insula, left lingual gyrus, right fusiform gyrus, and left cerebellum. At a less stringent level of significance, predicted areas in bilateral medial prefrontal cortex and right inferior parietal lobule covaried with SCR. Generation of discrete SCR events was associated with significant activity in left medial prefrontal cortex, bilateral extrastriate visual cortices, and cerebellum. Activity in right medial prefrontal cortex related to afferent representation of SCR events. Activity in bilateral medial prefrontal lobe, right orbitofrontal cortex, and bilateral extrastriate visual cortices was common to both generation and afferent representation of discrete SCR events identified in a conjunction analysis. Our results suggest that areas implicated in emotion and attention are differentially involved in generation and representation of peripheral SCR responses. We propose that this functional arrangement enables integration of adaptive bodily responses with ongoing emotional and attentional states of the organism.  (+info)

Impaired social response reversal. A case of 'acquired sociopathy'. (7/477)

In this study, we report a patient (J.S.) who, following trauma to the right frontal region, including the orbitofrontal cortex, presented with 'acquired sociopathy'. His behaviour was notably aberrant and marked by high levels of aggression and a callous disregard for others. A series of experimental investigations were conducted to address the cognitive dysfunction that might underpin his profoundly aberrant behaviour. His performance was contrasted with that of a second patient (C.L.A.), who also presented with a grave dysexecutive syndrome but no socially aberrant behaviour, and five inmates of Wormwood Scrubs prison with developmental psychopathy. While J.S. showed no reversal learning impairment, he presented with severe difficulty in emotional expression recognition, autonomic responding and social cognition. Unlike the comparison populations, J.S. showed impairment in: the recognition of, and autonomic responding to, angry and disgusted expressions; attributing the emotions of fear, anger and embarrassment to story protagonists; and the identification of violations of social behaviour. The findings are discussed with reference to models regarding the role of the orbitofrontal cortex in the control of aggression. It is suggested that J.S.'s impairment is due to a reduced ability to generate expectations of others' negative emotional reactions, in particular anger. In healthy individuals, these representations act to suppress behaviour that is inappropriate in specific social contexts. Moreover, it is proposed that the orbitofrontal cortex may be implicated specifically either in the generation of these expectations or the use of these expectations to suppress inappropriate behaviour.  (+info)

A study of changes in the status of autonomic nervous system in primary open angle glaucoma cases. (8/477)

Control of Intra Ocular Pressure (IOP) is influenced by both divisions (sympathetic and para-sympathetic) of Autonomic Nervous System (ANS). The present study was conducted to confirm existence of any association of ANS with primary open angle glaucoma (POAG), if present. Systemic autonomic function tests were assessed in fifty patients of POAG with fifty normal subjects matched for sex and age as control using several well established tests based on cardiovascular reflex responses to standardised stimuli viz. Resting heart rate (RHR), Corrected QT Interval (QTc), T-wave amplitude, Standing to Lying Ratio (SLR); Valsalva Ratio; Galvanic Skin Resistance (GSR) and Cold Pressor Test (CPR). Tests were conducted in the Department of Physiology, Maulana Azad Medical College and associated Glaucoma Clinic of Guru Nanak Eye Centre from june '94-May '95. Subjects were randomly chosen from known POAG cases with IOP--25 +/- 5.08 mm Hg. The results showed decrease in both sympathetic and para-sympathetic activity of autonomic function tests in POAG suggesting associated autonomic dysfunction. Sympathetic under-activity is seen in 36 patients out of 50 (73%), POAG subjects while para-sympathetic activity is decreased in 43 of 50 (86%) of the POAG subjects when compared with normal control group. The results help concluding that POAG is associated with autonomic dysfunction with decreased activity of both sympathetic and para-sympathetic divisions of ANS.  (+info)

Galvanic Skin Response (GSR), also known as Electrodermal Activity (EDA), is a physiological response that reflects the activation of the sympathetic nervous system. It measures changes in the electrical properties of the skin, which are influenced by the sweat gland activity. GSR is often used as an indicator of emotional arousal or psychological stress in various research and clinical settings.

In medical terms, the skin is the largest organ of the human body. It consists of two main layers: the epidermis (outer layer) and dermis (inner layer), as well as accessory structures like hair follicles, sweat glands, and oil glands. The skin plays a crucial role in protecting us from external factors such as bacteria, viruses, and environmental hazards, while also regulating body temperature and enabling the sense of touch.

Skin tests are medical diagnostic procedures that involve the application of a small amount of a substance to the skin, usually through a scratch, prick, or injection, to determine if the body has an allergic reaction to it. The most common type of skin test is the patch test, which involves applying a patch containing a small amount of the suspected allergen to the skin and observing the area for signs of a reaction, such as redness, swelling, or itching, over a period of several days. Another type of skin test is the intradermal test, in which a small amount of the substance is injected just beneath the surface of the skin. Skin tests are used to help diagnose allergies, including those to pollen, mold, pets, and foods, as well as to identify sensitivities to medications, chemicals, and other substances.

Alcoholic neuropathy is a type of nerve damage that occurs due to excessive alcohol consumption. It's caused by the toxic effects of alcohol and its byproducts on nerves throughout the body, particularly in the peripheral nervous system. The condition typically develops over time, with symptoms becoming more severe as alcohol abuse continues.

The symptoms of alcoholic neuropathy can vary widely depending on which nerves are affected. However, common symptoms include:

1. Numbness or tingling in the arms and legs
2. Muscle weakness and cramps
3. Loss of reflexes
4. Difficulty with balance and coordination
5. Pain or burning sensations in the extremities
6. Heat intolerance
7. Bladder and bowel dysfunction
8. Sexual dysfunction

Treatment for alcoholic neuropathy typically involves addressing the underlying alcohol abuse, as well as managing symptoms with medications and physical therapy. In severe cases, hospitalization may be necessary to monitor and manage complications. It's important to note that abstaining from alcohol is the only way to prevent further nerve damage and improve symptoms over time.
