  • cortical arousal
  • Stimulation of these axons and release of serotonin causes cortical arousal and impacts locomotion and mood. (wikipedia.org)
  • The existence of an externally initiated, internally present low-level coherent oscillation (perceived as binaural beating) within the central nervous system, and specifically the reticular formation, suggests a condition that may facilitate alterations of levels of cortical arousal. (monroeinstitute.org)
  • neurons
  • Here, we review the role of hypocretins/orexins in arousal state transitions, and discuss possible mechanisms by which such a relatively small population of neurons controls fundamental brain state dynamics. (springer.com)
  • Tachykinin-expressing neurons control male-specific aggressive arousal in Drosophila. (nih.gov)
  • dopamine
  • Another arousal system, the dopaminergic system, releases dopamine produced by the substantia nigra . (wikipedia.org)
  • Since aroused affiliation motivation was not associated with higher concentrations of norepinephrine, epinephrine, or cortisol in either study, it appears likely that dopamine is especially associated with arousal of affiliation motivation, just as norepinephrine has been found to be associated with arousal of power motivation. (springer.com)
  • hypothesis
  • Applying his hypothesis to heightened states of arousal-sex and fear-Pfaff shows us how his theory opens new scientific approaches to understanding the structure of brain arousal. (harvard.edu)
  • The results provide support for the hypothesis that the amygdala, and in particular the ACe, contributes to a heightened state of arousal during conditioned fear. (jneurosci.org)
  • sensory
  • Tk neuron activation overcame reduced aggressiveness caused by eliminating a variety of sensory or contextual cues, suggesting that it promotes aggressive arousal or motivation. (nih.gov)
  • researchers
  • Previously, sex researchers have measured arousal with instruments that require genital contact and manipulation. (medindia.net)
  • Principal investigator, Douglas Bradley, professor of medicine at the University of Toronto said that researchers involved in the study were surprised that using CPAP to alleviate CSA had no effect on arousals and no effect on sleep structure. (rxpgnews.com)
  • Hormone
  • When examined under an MRI, the brains of the men who received the hormone showed increased activity in the areas of the brain typically activated by sexual arousal and romance , and afterward reported a reduction in depressive symptoms. (aarp.org)
  • The hormone, called kisspeptin, was found to increase activity in areas of the brain normally stimulated by sexual arousal and romantic love. (medicalnewstoday.com)
  • disorder
  • Arousal disorder in patients with cardiac failure? (rxpgnews.com)
  • A study in the Jan. 1 issue of the journal Sleep demonstrates that the frequent arousals from sleep that occur in heart failure patients with central sleep apnoea (CSA) may reflect the presence of another underlying arousal disorder rather than being a defensive mechanism to terminate apnoeas. (rxpgnews.com)
  • The authors suggest that hear failure patients with CSA may have a "predisposition to hyperarousability," and in some there may be an underlying arousal disorder accompanied by sleep disruption that is neither a consequence of CSA nor of impaired cardiac function. (rxpgnews.com)
  • A mindfulness-based group psychoeducational intervention targeting sexual arousal disorder in women. (springer.com)
  • stimulation
  • In a study of some 24 multiethnic midlife women - Hispanic, White, African-American, Chinese and Japanese, a questionnaire revealed that about 40% felt that they never had or infrequently had sexual desire, but with stimulation were capable of arousal, but only 13% expressed content of their sexual experience. (cancersupportivecare.com)
  • phases
  • T a had no significant effect on the total cost of arousal episodes when all three phases are included. (springer.com)
  • intense
  • The traditional physiologically defined activation or arousal continuum, which ranges from intense emotion and vigorous activity on one extreme to calmness and sleep on the other, is rejected in favor of a psychological model with two activation dimensions and a single continuum of energy expenditure. (springer.com)
  • neural
  • Arousal is mediated by several different neural systems. (wikipedia.org)
  • Starting with a review of the neuroanatomical, neurophysiological, and neurochemical components of arousal, Pfaff asks us to look at the gene networks and neural pathways underlying the brain's arousal systems much as a design engineer would contemplate information systems. (harvard.edu)
  • Thus
  • Thus factors other than sleep apnoea such as pulmonary congestion during the night, other comorbidities, or medications, may explain the frequent arousals that heart failure patients experience. (rxpgnews.com)
  • psychological
  • There's an idea floating around in some psychological circles that one can, essentially, misplace their arousal (perhaps in the way one misplaces their keys: you think you left them on the steps, but they're actually in your coat pocket). (psychologytoday.com)
  • Authors
  • According to the authors, arousals in patients with obstructive sleep apnoea (OSA) are considered to be an important defense mechanism to terminate apnoeas, and treating OSA with CPAP immediately reduces the frequency of arousals. (rxpgnews.com)
  • research
  • In particular, recent research has demonstrated that human sexual arousal patterns can emerge in the absence of a history of instrumental learning or stimulus association. (thefreelibrary.com)
  • Although there has been limited applied research into the treatment of sexual dysfunction, basic research into the emergence and maintenance of sexual arousal patterns has been sparse by any standards. (thefreelibrary.com)
  • sexually
  • During the arousal experiment, the male and female subjects watched separate sexually explicit films procured from the Kinsey Institute and determined to be sexually arousing to specific genders. (medindia.net)
  • However, to my best understanding, sexual arousal comes into play when a sexually viable male and female willingly engage into in an intimate relationship. (supremeessays.com)
  • activity
  • It is crucial for motivating certain behaviours, such as mobility, the pursuit of nutrition, the fight-or-flight response and sexual activity (the arousal phase of Masters and Johnson 's human sexual response cycle ). (wikipedia.org)
  • The arousal may be triggered not only by sexual activity, but also by seemingly nonsexual situations or no obvious stimulus at all. (emaxhealth.com)
  • level
  • The Yerkes-Dodson law states that an optimal level of arousal for performance exists, and too little or too much arousal can adversely affect task performance. (wikipedia.org)
  • Dermer, M., & Bersheid, E. Self-report of arousal as an indicant of activation level. (springer.com)
  • play
  • In heart failure patients with CSA, arousal from sleep may be incidental to, or play a causative role in, the development of CSA by rendering the respiratory control system unstable. (rxpgnews.com)
  • pain
  • Some even go so far as to cause themselves pain during breastfeeding to combat their feelings of arousal or stop breastfeeding altogether. (columbia.edu)
  • love
  • Sweet love words, promises, and assurance on matters of faithfulness and trust are key pillars to strengthen the love and the willingness which also boots arousal. (supremeessays.com)
  • attention
  • Arousal is important in regulating consciousness , attention , alertness , and information processing . (wikipedia.org)
  • Comparative studies suggest that in fish and amphibia the nondirectional arousal component of the orientation reaction (OR) predominates over the directed attention component, the latter of which is more advanced in mammals. (springer.com)
  • suggest
  • Dutton & Aron (1974) suggest that these results were consistent with a type of " cognitive relabeling", where the arousal from fear becomes reinterpreted by the subjects as sexual attraction. (psychologytoday.com)
