[The role of the central substantia grisea of the midbrain in regulating the sound emission process in the bat Rhinolophus ferrumequinum].

Using axonal transport of HRP, relatively small region of the lateral part of the central gray matter of the midbrain was revealed the neurones of which send afferents to motoneurones of the vagal nucleus. It was shown that practically complete damage of the central gray matter does not affect temporal and frequency parameters of echo-sounding signals produced by animals during total location, do es not affect complex mechanism of stabilization of the filling frequency of these signals, as well as does not affect the ability of animals to decrease the filling frequency in relation to the rate of approaching the target.
