Aging is accompanied by the deterioration of hearing that complicates our understanding of
speech, especially in noisy environments. This deficit is partially caused by the loss of hair …

The avian auditory system has become a model system to investigate how vocalizations are
memorized and processed by the brain in order to mediate behavioral discrimination and …

Cortical representations supporting many cognitive abilities emerge from underlying circuits
comprised of several different cell types. However, cell type-specific contributions to rate and …

Primary vision segregates information along 2 main dimensions: orientation and spatial
frequency (SF). An important question is how this primary visual information is integrated to …

Songbird auditory neurons must encode the dynamics of natural sounds at many volumes.
We investigated how neural coding depends on the distribution of stimulus intensities. Using …

In this study, we explored ways to account more accurately for responses of neurons in
primary auditory cortex (A1) to natural sounds. The auditory cortex has evolved to extract …

Changes in the levels of gamma-aminobutyric acid (GABA) are known to occur in different
parts of the brain during aging. In our study we attempted to define the effect that aging has …

The interplay between excitation and inhibition in the auditory cortex is crucial for the
processing of acoustic stimuli. However, the precise role that inhibition plays in the …

Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the central
auditory system. Altered GABAergic neurotransmission has been found in both the inferior …

A central finding in many cortical areas is that single neurons can match behavioral
performance in the discrimination of sensory stimuli. However, whether this is true for natural …
