Preparation SPBSU-ODK_AVES-1-9 |
Description: A fragment of the dorsal hyperpallium (HD) of the telencephalon of a hooded crow. The image shows a short-axon aspiny stellate neuron from the HD. Note abundant axonal arborisations (axc) and aspiny dendrites (d). According to the E. Ramon-Moliner classification, this type of neurons belongs to the class of highly specialised idiodendritic neurons. The presence of such neurons in the birds brain indicates extremely high stage of neuronal organization of their pallium. This feature places corvids closer to primates; and dorsal regions of the hemispheres are comparable with cortex formations the mammals. Organs: сentral nervous system, cerebral brain or its part, neuron(s) Methods: Neurohistology - Golgi method of silver impregnation of nervous elements |
