Ketamine Found to Increase Brain Noise

This shows a diagram of a brainBy inhibiting NMDA receptors, ketamine increases noise to gamma frequencies in one layer of the thalamic nucleus and one lay of the somatosensory cortex. Findings suggest psychosis may be triggered by an increase in background noise impairing thalamocortical neurons which may be caused by a malfunction in NMDA receptors affecting the balance of inhibition and excitation in the brain.
