[The characteristics of the morphological structure of the endbrain in the hooded crow (Corvus corone cornix L.) and in the rock dove (Columba livia) in relation to their development of elementary reasoning activities].
The number of neurons in the endbrain [correction of forebrain] of two avian species--carrion crows and rock pigeons--was assessed. It was shown that the higher development of reasoning activity of crows is associated with greater number of cells in evolutionary new fields of hyperstriatum and greater number of cell complexes than in pigeons.
