Neuroscientists have long recognized the importance of understanding the underlying
principles of information processing by large populations of neurons. Methods for Neural …

Ensemble neuronal activity was recorded in each layer of the whisker area of the primary
somatosensory cortex (SI) while rats performed a whisker-dependent tactile discrimination …

Changes in spontaneous activity within the cortex recognized by subthreshold fluctuations of
the membrane potential of cortical neurons modified the response of cortical neurons to …

Haptic perception is an active process that provides an awareness of objects that are
encountered as an organism scans its environment. In contrast to the sensation of touch …

The biomechanics of a motor plant constrain the behavioral strategies that an animal has
available to extract information from its environment. We used the rat vibrissa system as a …

Chandelier cells form inhibitory axo-axonic synapses on pyramidal neurons with their
characteristic candlestick-like axonal terminals. The functional role of chandelier cells is still …

Activity in neocortex is often characterized by synchronized oscillations of neurons and
networks, resulting in the generation of a local field potential (LFP) and …

We studied the transformation of sensory input as it progresses from vibrissa primary sensor
(S1) to motor (M1) cortex. Single-unit activity was obtained from alert adult rats that did not to …

Brain networks are complex dynamical systems in which directed interactions between
different areas evolve at the sub-second scale of sensory, cognitive and motor processes …

The current view of whisker movement is that∼ 25 whiskers on each side of the face move
in synchrony. To determine whether whiskers are constrained to move together, we trained …
