Serotonin was shown to be involved in the mechanisms whereby olfactory bulbs controlled sexual receptivity between 18 and 19 hrs. on prooestrus in 4-day cyclic female rats. 相似文献

Summary The spontaneous discharge of some suprachiasmatic neurones in vivo and in vitro was found to exhibit a very constant interspike interval. In vivo these cells were comparatively rare and appeared to be mutually coupled. These findings are discussed in relation to coupled oscillator theories of circadian rhythm generation. 相似文献

Units responding to stretch of single extraocular muscles were found in the bulbar and cervical portion of the descending trigeminal nucleus of the lamb. The electrolysis of these bulbar sites provoked degeneration of nervous fibres which could be followed till the first cervical segment of the spinal cord. 相似文献

Résumé On a constaté que le neuroptile du noyau intermédio-latéral du rat contient de nombreux glomérules synaptiques gliaux encapsulés dans lesquels se trouve habituellement un dentrite ou axe terminal très visible surmonté par de petits boutons et des dentrites. Les glomérules sont accompagnés de synapses axo-axonaux qui peuvent être le corrolaire structural d'une inhibition présynaptique. La signification fonctionnelle des glomérules et des synapses axo-axonaux est discutée.

Summary The population of monoaminergic synaptic vesicles in the rat caudate nucleus remained unchanged or slightly decreased 3 h after chlorpromazine (CP) administration, and clearly increased after 24 h. The diameter of synaptic vesicles became smaller when the vesicles increased. These findings suggest that CP causes presynaptic blocking in part of its actions and leads to a condition in which neural transmission is inactive. In the control animals, population of the vesicles tended to fluctuate following the circadian rhythm. 相似文献
