Sensory environments change over a wide dynamic range and sensory processing can
change rapidly to facilitate stable perception. While rapid changes may occur throughout the …

In higher sensory cortices, there is a gradual transformation from sensation to perception
and action. In the auditory system, this transformation is revealed by responses in the rostral …

Primary sensory cortices are classically considered to extract and represent stimulus
features, while association and higher-order areas are thought to carry information about …

Precisely timed experimental manipulations of the brain and its sensory environment are
often employed to reveal principles of brain function. While complex and reliable pulse trains …

The ability to experimentally perturb biological systems has traditionally been limited to static
pre-programmed or operator-controlled protocols. In contrast, real-time control allows …

Auditory selective attention is required for parsing crowded acoustic environments, but
cortical systems mediating the influence of behavioral state on auditory perception are not …

Both generalized arousal and engagement in a specific task influence sensory neural
processing. To isolate effects of these state variables in the auditory system, we recorded …

The complexity of modern neurophysiology experiments requires specialized software to
coordinate multiple acquisition devices and analyze the collected data. We have developed …

Encoding properties of sensory neurons are commonly modeled using linear finite impulse
response (FIR) filters. For the auditory system, the FIR filter is instantiated in the spectro …
