Inputs to combination-sensitive neurons in the medial geniculate body of the mustached bat: the missing fundamental.
This study examined projections to combination-sensitive neurons in the medial geniculate body of the mustached bat. These specialized neurons respond to the combination of two temporally and spectrally distinct components of the bat's sonar pulse and echo, encoding target information. Combination-sensitive neurons respond to the bat's sonar fundamental, between 24-31 kHz, in conjunction with a...
متن کاملThe neurons of the medial geniculate body in the mustached bat (Pteronotus parnellii).
The neurons in the medial geniculate body were studied in Golgi preparations from adult mustached bats (Pteronotus parnellii). Their somatic and dendritic configurations were compared with those of cells in other, nonecholocating mammals. A second goal was to use the thalamic nuclear subdivisions derived from Golgi material to integrate the findings in parallel studies of cytoarchitecture, immu...
متن کاملFrequency organization and responses to complex sounds in the medial geniculate body of the mustached bat.
The auditory cortex of the mustached bat (Pteronotus parnellii) displays some of the most highly developed physiological and organizational features described in mammalian auditory cortex. This study examines response properties and organization in the medial geniculate body (MGB) that may contribute to these features of auditory cortex. About 25% of 427 auditory responses had simple frequency ...
متن کاملDirectional selectivity for FM sweeps in the suprageniculate nucleus of the mustached bat medial geniculate body.
Mustached bats emit echolocation and communication calls containing both constant frequency (CF) and frequency-modulated (FM) components. Previously we found that 86% of neurons in the ventral division of the external nucleus of the inferior colliculus (ICXv) were directionally selective for linear FM sweeps and that selectivity was dependent on sweep rate. The ICXv projects to the supragenicul...
متن کاملCombination-sensitive neurons in the primary auditory cortex of the mustached bat.
In the mustached bat, Pteronotus parnellii, neurons in the primary auditory cortex (AI) have been thought to respond primarily to single frequencies, as in other mammals. However, neurons in the Doppler-shifted constant-frequency (DSCF) area, a part of the mustached bat's AI that contains an overrepresentation of the prominent CF2 component of the biosonar signal, were found to show facilitativ...
