Encoding of whisker vibration by rat barrel cortex neurons: implications for texture discrimination
E Arabzadeh, RS Petersen… - Journal of …, 2003 - Soc Neuroscience
Rats, using their whiskers, have excellent capabilities in texture discrimination. What is the
representation of texture in rat somatosensory cortex? We hypothesize that as rats “whisk” …

Opposite adaptive processing of stimulus intensity in two major nuclei of the somatosensory brainstem
Tactile information ascends from the brainstem to the somatosensory cortex via two major
parallel pathways, lemniscal and paralemniscal. In both pathways, and throughout all …

[PDF][PDF] The nature of shared cortical variability
Neuronal responses of sensory cortex are highly variable, and this variability is correlated
across neurons. To assess how variability reflects factors shared across a neuronal …

Temporal contingencies determine whether adaptation strengthens or weakens normalization
A fundamental and nearly ubiquitous feature of sensory encoding is that neuronal
responses are strongly influenced by recent experience, or adaptation. Theoretical and …
