Release of endogenous serotonin from "encéphale isolé" cats. II - Correlations with raphe neuronal activity and sleep and wakefulness. 1979

J J Puizillout, and G Gaudin-Chazal, and A Daszuta, and N Seyfritz, and J P Ternaux

The discharge pattern of single neurons localized in raphe nuclei dorsalis and centralis superior was recorded in "encéphale isolé" cats, during sleep and wakefulness episodes occurring spontaneously or triggered by vago-aortic stimulation. In both nuclei, a similar and progressive decrease in frequency of discharges is generally observed during shifts between wakefulness, the transitional phase of sleep and paradoxical sleep. In addition, the release of serotonin (5-HT) has been studied with push-pull cannulae (caudate nucleus level) and superfusion techniques (cortical associative area) in relation to the different stages of consciousness. The results showed a clear diminution of endogenous 5-HT released during spontaneously occurring or vago-aortic triggered sleep.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D001933 Brain Stem The part of the brain that connects the CEREBRAL HEMISPHERES with the SPINAL CORD. It consists of the MESENCEPHALON; PONS; and MEDULLA OBLONGATA. Brainstem,Truncus Cerebri,Brain Stems,Brainstems,Cerebri, Truncus,Cerebrus, Truncus,Truncus Cerebrus
D002415 Cats The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D002540 Cerebral Cortex The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulci. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.

D003655 Decerebrate State A condition characterized by abnormal posturing of the limbs that is associated with injury to the brainstem. This may occur as a clinical manifestation or induced experimentally in animals. The extensor reflexes are exaggerated leading to rigid extension of the limbs accompanied by hyperreflexia and opisthotonus. This condition is usually caused by lesions which occur in the region of the brainstem that lies between the red nuclei and the vestibular nuclei. In contrast, decorticate rigidity is characterized by flexion of the elbows and wrists with extension of the legs and feet. The causative lesion for this condition is located above the red nuclei and usually consists of diffuse cerebral damage.
