[Interaction of brain structures participating in vocalization].
The study revealed a broad representation of the system, controlling vocalization, in the brain structures of hens. Sound-producing structures are mostly represented in the mesencephalon, less--in the diencephalon and the least of all--in the striatum. Further on it is shown that the excitability of the structures at the mesencephalic and diencephalic levels participating in vocalization, is influenced by the corticoid lamine and striate formations (Hyperstriatum, Neostriatum). Forward and backward interconnections are revealed between the paliostriatum and soundproducing formations in the midbrain. Such functional connections, providing for excitatory or inhibitory control, are found between the neostriatum and the diencephalic structures. A suggestion is made, that vocalization processes proceed simultaneously in several parallel anatomic pathways.
