[Characteristics of neurons from the anterior region of the rat amygdaloid body by electron microscopy].
Dark and light neurons with morphological signs of secretory activity are described within one of the major sexually dimorphic zones of brain amygdaloid nucleus (anterior cortical nucleus). Dark neurons are of medium size, they have large nuclei and well developed perikarya. The latter contain numerous free ribosomes and mitochondria, dilated rough endoplasmic reticulum cisterns, hypertrophied Golgi complex with forming secretory granules. Elementary neurosecretory granules (ENG) 75-300 nm in size were found in light neurosecretory cells, which seem to be similar to dark cells but are at different phase of functional activity. Synapses of all types known, containing small light vesicles, vesicles with dense core and ENG, were found in active neuropil.
