Midbrain local circuits shape sound intensity codes.

Hierarchical processing of sensory information requires interaction at multiple levels along the peripheral to central pathway. Recent evidence suggests that interaction between driving and modulating components can shape both top down and bottom up…

Exploiting development to evaluate auditory encoding of amplitude modulation.

During development, detection for many percepts matures gradually. This provides a natural system in which to investigate the neural mechanisms underlying performance differences: those aspects of neural activity that mature in conjunction with…

Coding the meaning of sounds: contextual modulation of auditory responses in the basolateral amygdala.

Female mice emit a low-frequency harmonic (LFH) call in association with distinct behavioral contexts: mating and physical threat or pain. Here we report the results of acoustic, behavioral, and neurophysiological studies of the contextual analysis…

Brief Stimulus Exposure Fully Remediates Temporal Processing Deficits Induced by Early Hearing Loss.

In childhood, partial hearing loss can produce prolonged deficits in speech perception and temporal processing. However, early therapeutic interventions targeting temporal processing may improve later speech-related outcomes. Gap detection is a…

Temporal features of spectral integration in the inferior colliculus: effects of stimulus duration and rise time.

This report examines temporal features of facilitation and suppression that underlie spectrally integrative responses to complex vocal signals. Auditory responses were recorded from 160 neurons in the inferior colliculus (IC) of awake mustached bats.…

Frequency 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…

Excitatory and facilitatory frequency response areas in the inferior colliculus of the mustached bat.

In the mustached bat's central nucleus of the inferior colliculus (ICC), many neurons display facilitatory or inhibitory responses when presented with two tones of distinctly different frequencies. Our previous studies have focused on spectral…

Metabotropic glutamate receptors in auditory processing.

As the major excitatory neurotransmitter used in the vertebrate brain, glutamate activates ionotropic and metabotropic glutamate receptors (mGluRs), which mediate fast and slow neuronal actions, respectively. Important modulatory roles of mGluRs have…

Neural processing of target distance by echolocating bats: functional roles of the auditory midbrain.

Using their biological sonar, bats estimate distance to avoid obstacles and capture moving prey. The primary distance cue is the delay between the bat's emitted echolocation pulse and the return of an echo. The mustached bat's auditory midbrain…
