High concentrations of divalent cations isolate monosynaptic inputs from local circuits in the auditory midbrain.

Hierarchical processing of sensory information occurs at multiple levels between the peripheral and central pathway. Different extents of convergence and divergence in top down and bottom up projections makes it difficult to separate the various…

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…

Spectral integration in the inferior colliculus of the mustached bat.

Acoustic behaviors including orientation and social communication depend on neural integration of information across the sound spectrum. In many species, spectral integration is performed by combination-sensitive neurons, responding best when…

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…

Roles of inhibition in complex auditory responses in the inferior colliculus: inhibited combination-sensitive neurons.

We studied the functional properties and underlying neural mechanisms associated with inhibitory combination-sensitive neurons in the mustached bat's inferior colliculus (IC). In these neurons, the excitatory response to best frequency tones was…

Intracellular recording reveals temporal integration in inferior colliculus neurons of awake bats.

The central nucleus of the inferior colliculus (IC) is a major integrative center in the central auditory system. It receives information from both the ascending and descending auditory pathways. To determine how single IC neurons integrate…

L-type calcium channels refine the neural population code of sound level.

The coding of sound level by ensembles of neurons improves the accuracy with which listeners identify how loud a sound is. In the auditory system, the rate at which neurons fire in response to changes in sound level is shaped by local networks.…

A novel coding mechanism for social vocalizations in the lateral amygdala.

The amygdala plays a central role in evaluating the significance of acoustic signals and coordinating the appropriate behavioral responses. To understand how amygdalar responses modulate auditory processing and drive emotional expression, we assessed…

Glycinergic inhibition creates a form of auditory spectral integration in nuclei of the lateral lemniscus.

For analyses of complex sounds, many neurons integrate information across different spectral elements via suppressive effects that are distant from the neurons' excitatory tuning. In the mustached bat, suppression evoked by sounds within the first…

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…

Topographical distribution of delay-tuned responses in the mustached bat inferior colliculus.

In the mustached bat, delay-tuned neurons respond best to specific delays between the first harmonic frequency modulated (FM) component (FM1; 24-29 kHz) of the emitted biosonar pulse and a higher harmonic FM component in returning echoes (e.g. FM3,…

Selectivity and persistent firing responses to social vocalizations in the basolateral amygdala.

This study examined responsiveness to acoustic stimuli among neurons of the basolateral amygdala. While recording from single neurons in awake mustached bats (Pteronotus parnellii), we presented a wide range of acoustic stimuli including tonal,…

Substrates of auditory frequency integration in a nucleus of the lateral lemniscus.

In the intermediate nucleus of the lateral lemniscus (INLL), some neurons display a form of spectral integration in which excitatory responses to sounds at their best frequency are inhibited by sounds within a frequency band at least one octave…

Timing of sound-evoked potentials and spike responses in the inferior colliculus of awake bats.

Neurons in the inferior colliculus (IC), one of the major integrative centers of the auditory system, process acoustic information converging from almost all nuclei of the auditory brain stem. During this integration, excitatory and inhibitory inputs…

An operant-based detection method for inferring tinnitus in mice.

BACKGROUND: Subjective tinnitus is a hearing disorder in which a person perceives sound when no external sound is present. It can be acute or chronic. Because our current understanding of its pathology is incomplete, no effective cures have yet been…

Combination-sensitive neurons in the inferior colliculus.

We examined whether neurons in the inferior colliculus of the mustached bat (Pteronotus parnellii) are combination sensitive, responding to both low- and high-frequency components of the bat's sonar signal. These neurons, previously reported in the…
