This state-of-art approach was developed in parallel in human and monkey over the last 5 years within the MRI platform of the Institut des Sciences du Cerveau de Toulouse on the site of the Purpan hospital. This platform is one of the first in France that was specifically designed for studies in both human and macaque. Numerous tests were necessary for the establishment of fMRI sequences, the development of specific coils but also for the processing of the data and the conditioning of the animals. The results, published in Cerebral Cortex, revealed that despite some differences, the cortical networks activated during locomotion in macaques are very close to those obtained in humans using the same experimental approach. They allow a better understanding of the homologies between the two species and open new perspectives on our current knowledge of brain function evolution in primate. ...

EphA7 est un membre de la famille des récepteurs à tyrosine kinase Eph, qui régulent ladhérence et la motilité cellulaires. EphA7 est hautement conservé chez les vertébrés et largement exprimé durant lembryogenèse, en particulier pendant le développement du SNC. Dans le cerveau adulte, EphA7 est transcrit principalement dans lhippocampe, avec de faibles niveaux dexpression ailleurs. Nous avons cartographié sa distribution dans le cerveau du rat et de la souris adultes, par hybridation in situ et immunohistochimie en microscopie photonique et électronique. Les deux méthodes montrent une distribution de marquage très cohérente. Le signal le plus fort a été observé dans lhippocampe, avec des niveaux moins élevés dans lhabénula, le striatum, lamygdale, les cortex cingulaire, piriforme et entorhinal, ainsi que le cervelet. Au niveau ultrastructural, dans lhippocampe, limmunoréactivité dEphA7 a été localisée dans le cytoplasme des cellules granulaires (gyrus ...

TY - JOUR. T1 - Spinal estrogen attenuates the exercise pressor reflex but has little effect on the expression of genes regulating neurotransmitters in the dorsal root ganglia. AU - Schmitt, Petra M.. AU - Gohil, Kishorchandra. AU - Kaufman, Marc P.. PY - 2006/3/1. Y1 - 2006/3/1. N2 - Previously, our laboratory showed that estrogen, topically applied to the spinal cord, attenuated the exercise pressor reflex in female cats (Schmitt PM and Kaufman MP. J Appl Physiol 95: 1418-1424, 2003; 98: 633-639, 2005). The attenuation was gender specific and was in part opioid dependent. Our finding that the μ- and δ-opioid antagonist naloxone was only able to partially restore estrogens attenuating effect on the pressor response to static contraction suggested that estrogen affected an additional pathway, involving the dorsal root ganglion (DRG). Estrogen has been described to stimulate transcription within 10 min of its application to the DRG, raising the possibility that rapid genomic effects on ...

Quoique très immature à la naissance, lopossum grimpe de lorifice urogénital de la mère jusquà une tétine à laquelle il saccroche pour poursuivre sa maturation. Des informations sensorielles sont nécessaires pour que lanimal atteigne la tétine et que le réflexe dattachement soit déclenché. Une modalité sensorielle envisagée est lolfaction. Or, des expériences physiologiques effectuées au laboratoire sur des préparations in vitro suggèrent que le système olfactif central est trop immature pour influencer les comportements moteurs. Une étude immunohistochimique employant un marqueur de maturité axonique (NF200) a montré une absence de marquage dans le cerveau antérieur, à lexception dun mince faisceau reliant les bulbes olfactifs aux régions caudales du cerveau. Limplication de lolfaction dans les comportements du nouveau-né est donc peu probable, mais la présence de ce faisceau est intrigante et létude de son développement est approfondie dans le présent ...

Patients did not receive aldesleukin during the extension phase ...
One of the postural reflexes of crayfish, the uropod steering response, is elicited by specific sensory inputs while the animal is walking. It is not elicited, however, by the same inputs when the animal is at rest. To clarify the neuronal mechanisms underlying this facilitatory control of body posture in the active animals, we used intracellular recordings to analyse the synaptic activities of uropod motor system neurones in an unanaesthetized whole-animal preparation. Several uropod motoneurones were found to receive sustained depolarizing inputs during walking, whereas the walking leg motoneurones sampled always showed rhythmic activity. The membrane conductance of the uropod motoneurones increased during the sustained synaptic activity. Premotor nonspiking interneurones showed depolarizing or hyperpolarizing membrane potential changes during walking that were also accompanied by increases in membrane conductance. Some of these interneurones enhanced uropod motoneurone activity, whereas ...

TY - JOUR. T1 - Estrogen attenuates the exercise pressor reflex in female cats. AU - Schmitt, Petra M.. AU - Kaufman, Marc P. PY - 2003/10/1. Y1 - 2003/10/1. N2 - In humans, the pressor and muscle sympathetic nerve responses to static exercise are less in women than in men. The difference has been attributed to the effect of estrogen on the exercise pressor reflex. Estrogen receptors are abundant in areas of the dorsal horn receiving input from group III and IV muscle afferents, which comprise the sensory limb of the exercise pressor reflex arc. These findings prompted us to investigate the effect of estrogen on the spinal pathway of the exercise pressor reflex arc. Previously, we found that the threshold concentration of 17β-estradiol needed to attenuate the exercise pressor reflex in male decerebrate cats was 10 μg/ml (Schmitt PM and Kaufman MP. J Appl Physiol 94: 1431-1436, 2003). The threshold concentration for female cats, however, is not known. Consequently, we applied 17β-estradiol to ...
TY - JOUR. T1 - Both central command and exercise pressor reflex activate cardiac sympathetic nerve activity in decerebrate cats. AU - Tsuchimochi, Hirotsugu. AU - Hayes, Shawn G.. AU - McCord, Jennifer L.. AU - Kaufman, Marc P. PY - 2009/4. Y1 - 2009/4. N2 - Both static and dynamic exercise are known to increase cardiac pump function as well as arterial blood pressure. Feedforward control by central command and feedback control by the exercise pressor reflex are thought to be the neural mechanisms causing these effects during exercise. It remains unknown as to how each mechanism activates cardiac sympathetic nerve activity (CSNA) during exercise, especially at its onset. Thus we examined the response of CSNA to stimulation of the mesencephalic locomotor region (MLR, i.e., central command) and to static muscle contraction of the triceps surae muscles or stretch of the calcaneal tendon in decerebrate cats. We found that MLR stimulation immediately increased CSNA, which was followed by a gradual ...
TY - JOUR. T1 - Vasopressor response to angiotensin II infusion in patients with chronic heart failure receiving β-blockers. AU - Vittorio, Timothy J.. AU - Lang, Chim C.. AU - Katz, Stuart D.. AU - Packer, Milton. AU - Mancini, Donna M.. AU - Jorde, Ulrich P.. PY - 2003/1/21. Y1 - 2003/1/21. N2 - Background - A synergistic interaction between the angiotensin II (Ang II) type 1 receptor and α1-adrenergic receptors has been described. We hypothesized that the nonselective β-antagonist carvedilol, through its α1-adrenergic blocking properties, may modulate vascular reactivity to Ang II in patients with chronic heart failure (CHF). Accordingly, we compared the vasopressor response to infused Ang II in patients treated with carvedilol and metoprolol, a selective β-antagonist. Methods and Results - All subjects were treated with carvedilol or metoprolol for at least 3 months. ACE inhibitor therapy was standardized to enalapril 40 mg/d or the maximally tolerated dose. Exogenous Ang II was ...
AUTO GENIC INHIBITION. Activity in the group Ib afferent fibers, associated with Golgi tendon organs, inhibits the homonymous alpha-moto neurons. The inhibition is disynaptic involving one interneuron and two synapses between the afferent fiber and the moto neuron. The effect is called autogenic inhibition (sometimes written autogenetic inhibition). Like the group Ia excitation, group Ib inhibition is exerted not only on the homonymous alpha-moto neurons, but also on the alpha-moto neurons of synergistic muscles. Reciprocal innervations is also present here, with group Ib activity exciting the alpha-moto neurons of the antagonist muscles. It was originally thought that this inhibition served only to protect the muscle from being injured when contracting against too heavy a load. This concept came from two sources: (1) the supposed high threshold of group Ib fibers to tension (not true for developed tension) and (2) the existence of a clasp-knife reflex. The clasp-knife reflex exists only in ...

Inhalation is a likely route for exposure to the substance in regular use. According to ECHA guidance document the oral NOAEL (200 mg/kg bw/d, derived from the oral OECD407 study) is converted to an inhalatory NOAEC Worker as follows: 200 mg/kg bw /d / 0.38 m3/kg/d * 6.7 m3/10m3 * 10/10 = 352.6 mg/m3, whereas the first factor accounts for different respiratory volume from rats to humans, the second factor considers light weight activity respiratory volume increase by workers and the third factor takes account of an anticipated absorption via inhalative route compared to oral route (i.e. 10% for oral absorption, and 10% for inhalation ...
KEY POINTS: During exercise, blood pressure (BP) response is exaggerated in peripheral artery disease (PAD). We examined whether heat treatment (HT) has beneficial effects on the exaggerated exercise pressor reflex in PAD rats. With HT (increase in the Tm of â ¼1.5°C for 30 min, 2 times daily for 3 continuous days), the amplified BP response to muscle contraction is alleviated in PAD. We demonstrated that HT attenuates the enhancement of the BP response induced by stimulation of P2X in muscle afferent nerves of PAD rats. HT also attenuates the upregulation of the P2X3 and the increase in P2X currents in the muscle afferent neurons of PAD rats. Prior heat exposure plays a beneficial role in modifying the exaggeration of the exercise pressor reflex in PAD and a reduction in the activity of the P2X receptor pathway is likely a part of the mechanism mediating this improvement. ABSTRACT: The current study was performed to examine if heat treatment (HT) has beneficial effects on the exaggerated ...
In Japan, decapitation was a common punishment, sometimes for minor offenses. Samurai were often allowed to decapitate soldiers who had fled from battle, as it was considered cowardly. Decapitation was historically performed as the second step in seppuku (ritual suicide by disembowelment). After the victim had sliced his own abdomen open, another warrior would strike his head off from behind with a katana to hasten death and to reduce the suffering. The blow was expected to be precise enough to leave intact a small strip of skin at the front of the neck-to spare invited and honored guests the indelicacy of witnessing a severed head rolling about, or towards them; such an event would have been considered inelegant and in bad taste. The sword was expected to be used upon the slightest sign that the practitioner might yield to pain and cry out-avoiding dishonor to him and to all partaking in the privilege of observing an honorable demise. As skill was involved, only the most trusted warrior was ...
