Influence of the thalamus on spatial visual processing in frontal cortex

Article Abstract:

An experiment was carried out to explain the critical missing link that is the connection between corollary discharge and visual processing and it is shown that the link is formed by a corollary discharge from the thalamus that targets the frontal cortex. The findings establish the first link between corollary discharge and visual processing, delineate a brain circuit that is well suited for mediating visual stability, and provide a framework for studying corollary discharge in other sensory systems.

Spikes to kinky in the cortex?

Article Abstract:

Hodgkin and Huxley proposed a mechanistic model by which spikes are generated in an electrically excitable membrane. The Hodgkin-Huxley theory explains the mechanism of how neurons fire forms the cornerstone of computational neuroscience and something it has not predicted is happening in the brain cortex.

Analgesia and hyperalgesia from GABA-mediated modulation of the cerebral cortex

Article Abstract:

Pain perception can be altered by mood, attention and cognition or by direct stimulation of the cerebral cortex. GABA neurotransmission in the Rostra Granular Insular Cortex (RAIC) can raise or lower the pain threshold.
