...Emanuel C. Mora; Yohami Fernández; Julio Hechavarría; Martha Pérez Frequency alternation in the echolocation of insectivorous bats has been interpreted in relation to ranging and duty cycle, i.e. advantages for echolocation. The shifts in frequency of the calls of these so-called two-tone bats...

The relationship between the degree of development of the acoustic nuclei and the feeding habits as well as echolocative skills has been discussed. Fish-eating Noctilio leporinus has...

...W.

Nuclei Although the background for the theory arose in part from an attempt to relate physiological phenomena in the IC of bats to echolocation behavior, one piece of evidence that was especially influential was the fact that most neu­ rons in the IC and higher centers can not be driven al a rapid rate...
