During object manipulation tasks, the brain selects and implements action-phase controllers
that use sensory predictions and afferent signals to tailor motor output to the physical …

Does the brain use a firing rate code or a spike timing code? Considering this controversial
question from an epistemological perspective, I argue that progress has been hampered by …

The problem of consciousness continues to be a subject of great debate in cognitive
science. Synthesizing decades of research, The Conscious Brain advances a new theory of …

Sensory, motor and cortical neurons fire impulses or spikes at a regular, but slowly
declining, rate in response to a constant current stimulus. Yet, the intervals between spikes …

Neocortical assemblies produce complex activity patterns both in response to sensory
stimuli and spontaneously without sensory input. To investigate the structure of these …

Electrical microstimulation can establish causal links between the activity of groups of
neurons and perceptual and cognitive functions,,,,,. However, the number and identities of …

Individual pyramidal neurons of neocortex show sparse and variable responses to sensory
stimuli in vivo. It has remained unclear how this variability extends to population responses …

Inhibitory neurons play a fundamental role in cortical computation and behavior. Recent
technological advances, such as two photon imaging, targeted in vivo recording, and …

Decoding the activity of a population of neurons is a fundamental problem in neuroscience.
A key aspect of this problem is determining whether correlations in the activity, ie, noise …

Response variability is often correlated across populations of neurons, and these noise
correlations may play a role in information coding. In previous studies, this possibility has …
