Collection: Brain of the birds (Aves)

Species: Corvus cornix Linnaeus, 1758    Aves

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.
