Sounds in everyday life seldom appear in isolation. Both humans and machines are
constantly flooded with a cacophony of sounds that need to be sorted through and scoured�…

As sensory stimuli and behavioral demands change, the attentive brain quickly identifies
task-relevant stimuli and associates them with appropriate motor responses. The effects of�…

Humans can easily focus on one speaker in a multi-talker acoustic environment, but how
different areas of the human auditory cortex (AC) represent the acoustic components of�…

For several decades, auditory neuroscientists have used spectro-temporal encoding models
to understand how neurons in the auditory system represent sound. Derived from early�…

Complex natural and environmental sounds, such as speech and music, convey information
along both spectral and temporal dimensions. The cortical representation of such stimuli�…

Highlights•Models of early auditory processing explain how stable perceptual attributes
emerge.•Pre-attentive Adaptive Coding and Stimulus Specific Adaptation enable dynamic�…

Perception of vocalizations and other behaviorally relevant sounds requires integrating
acoustic information over hundreds of milliseconds. Sound-evoked activity in auditory cortex�…

The challenge of understanding how the brain processes natural signals is compounded by
the fact that such signals are often tied closely to specific natural behaviors and natural�…

We consider the problem of estimating the sparse time-varying parameter vectors of a point
process model in an online fashion, where the observations and inputs respectively consist�…

In this paper, a new feature extraction method is presented based on spectro-temporal
representation of speech signal for phoneme classification. In the proposed method, an�…
