Anatomy and projection patterns of the superior olivary complex in the Mexican free-tailed bat, Tadarida brasiliensis mexicana.
The superior olivary complex (SOC) is the first station in the ascending auditory pathway that receives binaural projections. Two of the principal nuclei, the lateral superior olive (LSO) and the medial superior olive (MSO), are major sources of ascending projections to the inferior colliculus. Whereas almost all mammals have an LSO, it has traditionally been thought that only animals that hear...
متن کاملVocal Recognition of Pups by Mother Mexican Free-Tailed Bats, Tadarida brasiliensis mexicana
The ability of Mexican free-tailed bat mothers and pups to recognize vocalizations of their presumptive kin (pup isolation calls and mother echolocation calls, respectively) was tested using playbacks of recorded calls. Captive individuals were presented with calls of two bats, one presumptive kin and the other a stranger, from opposite sides of a circular wire arena. Response was determined by...
متن کاملSerotonergic innervation of the auditory brainstem of the Mexican free-tailed bat, Tadarida brasiliensis.
Anatomical and electrophysiological evidence suggests that serotonin alters the processing of sound in the auditory brainstem of many mammalian species. The Mexican free-tailed bat is a hearing specialist, like other microchiropteran bats. At the same time, many aspects of its auditory brainstem are similar to those in other mammals. This dichotomy raises an interesting question regarding the s...
متن کاملA Categorization of Mexican Free-Tailed Bat (Tadarida brasiliensis) Chirps ýýýýý
Male Mexican Free-tailed Bats (Tadarida brasiliensis) attract mates and defend territory using multi-phrase songs that have a structured set of rules. A subjective view of their spectrograms shows similarity and dissimilarity between the chirps (a syllable within the song) of different males. We developed a rigorous algorithm to characterize the shapes of these chirps. The discrete Fourier tran...
متن کاملFemale dietary bias towards large migratory moths in the European free-tailed bat (Tadarida teniotis).
In bats, sexual segregation has been described in relation to differential use of roosting and foraging habitats. It is possible that variation may also exist between genders in the use of different prey types. However, until recently this idea was difficult to test owing to poorly resolved taxonomy of dietary studies. Here, we use high-throughput sequencing to describe gender-related variation...
