A tectum opticum peptiderg Ă©s GABAerg idegsejtjeinek kapcsolatai = Connections of the peptidergic and GABAerg neurons of the optic tectum
1. NOS immunreaktiv (ir) neuronok, nem kĂĽldenek axont a thalamusba Ă©s a nucl. isthmibe. 2. A lazac Ă©s patkány MCH- Ă©s glutamat-izoleucin-szerű immunreakciĂł a bĂ©ka elĹ‘agyában (bulbus olfact., pallium lat., septum, amygdala), a közĂ©p- Ă©s utĂłagyban, gerincvelĹ‘ben idegrostokban találhatĂł. A köztiagyban a látĂłköypontok Ă©s a habenula kivĂ©telĂ©vel mindenhol volt ir rost. Sejtek: nucl. centralis thalami, nucl. suprachiasmat., hypothalamus. 3. Urocortin-ir rostok: septum, thalamus, hypothalamus, tectum, tegm. mesencephali, torus semicirc., a gerincvelĹ‘ hátsĂł szarva, intermedier zĂłnája, a kisagy szemcsĂ©s rĂ©tege, hallĂłmag. Ir neuronok: preoptikus area, nucl. ventromed. thalami, tuberc. post., Edinger-Westfal mag. 4. A CART peptid idegrendszeri lokalizáciĂłja kecskebĂ©kában Ă©s afrikai karmos bĂ©kában hasonlĂł. CARTp-ir sejtek Ă©s rostok: bulbus olfact., nucl. accumbens, pallium med., striatum, septum, amygdala, preoptikus terĂĽlet, nucl. centralis Ă©s ventromed. thalami, hypothalamus, tectum, Edinger-Westhphal mag, agytörzs, gerincvelĹ‘ nucl. intermediolat. A motoneuronok körĂĽli fonatok egy felszállĂł pálya vĂ©gzĹ‘dĂ©sei. KecskebĂ©kában a bulbus olfactoriusban volt a legerĹ‘sebb festĹ‘dĂ©s, Xenopusban a tectumban. 5. A CARTp ir boutonok szorosan hozzáfekszenek a neuron sejtmembránjához. Szinaptikus kapcsolatok ritkák, kicsik, szimmetrikusak. Az axon vĂ©gzĹ‘dĂ©ssel szemben a felszĂn alatti lapos ciszternák elektrondenz membránjai láthatĂłk. | 1. Nitric oxide synthase immunoreactive (ir) neurons do not project to the thalamus and the isthmic nucleus. 2. Salmon and rat MCH-like, and glutamate-isoleucine-like immunoreactivity occur in nerve fibres in the frog telencephalon (olfactory bulb, lat. pallium, diagonal band, septum, amygdala), mes- and rhombencephalon, spinal cord. In the diencephalon, ir fibres were also found with the exception of retinal projection areas and the habenula. Ir cells: central- and ventromed. thalamic and suprachias. nuclei, hypothalamus. 3. Urocortine-ir fibres: septum, thalamus, hypothal., tectum, tegm. mesencephali, torus semicirc., dorsal horn and intermediet zone of the spinal cord, granular layer of the cerebellum, cochlear nucl. Ir neurons: preoptic area, ventromed. thalamic nucl., post. tubercle, Edinger-Westfal nucl. 4. Location of CART-peptide in the CNS of Rana and Xenopus is similar. CARTp-ir cells and nerve fibres: olf. bulb, accumbens nucl., med. pallium, striatum, septum, amygdala, preoptic area, central and ventromed. thalamic nucl., hypothal., tectum, Edinger-Westfal nucl., brain stem, intermediate zone of spinal cord. Terminals of ascending fibres form plexuses around motoneurons. The strongest immunoreactivity in Rana occurred in the olf. bulb, and in the tectum of Xenopus. 5. CARTp-ir boutons form close appositions on motoneurons. Synapses are rare, small and symmetric. Opposite to the axon terminal, electrondense membranes of subsurface cysterns occur
