Synapses and receptive fields of the cerebral cortex are plastic. However, changes to
specific inputs must be coordinated within neural networks to ensure that excitability and …

Cortical sensory processing is modulated by behavioral and cognitive states. How this
modulation is achieved by changing synaptic circuits remains largely unknown. In awake …

Receptive fields of sensory cortical neurons are plastic, changing in response to alterations
of neural activity or sensory experience,,,,,,,,,,,. In this way, cortical representations of the …

Sensory experience alters the functional organization of cortical networks. Previous studies
using behavioral training motivated by aversive or rewarding stimuli have demonstrated that …

Cholinergic basal forebrain (CBF) signaling exhibits multiple timescales of activity with
classic slow signals related to brain and behavioral states and fast, phasic signals reflecting …

Behavioural engagement can enhance sensory perception. However, the neuronal
mechanisms by which behavioural states affect stimulus perception remain poorly …

Neocortical responses typically adapt to repeated sensory stimulation, improving sensitivity
to stimulus changes, but possibly also imposing limitations on perception. For example, it is …

Top-down signals from frontal cortex are thought to be important in cognitive control of
sensory processing. To explore this interaction, we compared activity in ferret frontal cortex …

Neurons in the recipient layers of sensory cortices receive excitatory input from two major
sources: the feedforward thalamocortical and recurrent intracortical inputs. To address their …

The nucleus basalis of the basal forebrain is an essential component of the
neuromodulatory system controlling the behavioral state of an animal and it is thought to be …
