[Impregnoarchitectonic study of neurons in the caudal hypothalamic area in sheep].

The impregnoarchitectonics of neurons in the regio hypothalamica caudalis was studied by the methods after Ramón-Moliner and Golgi-Cox. Neuron types, morphology of synaptic conjugations and orientation of dendrites and axons are indicated for each nucleus. Small spindle-shaped neurons are the most frequent neuron forms occurring in the regio hypothalamica caudalis. It is only in the nucl. hypothalamicus perifornicalis that neuron processes and the long cell axes are oriented around the columna fornicis. One especially large neuron "occupies" the dorsal part of this nucleus.
