Interruption of functional recovery by the NMDA glutamate antagonist MK801 after compression of the sensorimotor cortex: implications for treatment of tumors or other mass-related brain injuries

Experimental Neurology

Abstract

Glutamate antagonists have recently been shown to limit tumor growth, providing potential new therapeutic targets and strategies against brain tumors. Here, we demonstrate that the glutamate NMDA receptor antagonist MK801, after a delay, adversely reverses functional recovery in rats with compressive mass lesions of the sensorimotor cortex. Our data suggest that the controlled focal cortical compression model may be a valuable pre-clinical tool to screen compounds for the treatment of brain tumors. It may be possible to use this model to develop interventions that maintain anti-cancer effects but with diminished harm to bystander tissue and brain plasticity.

Barrel cortex

Here is the latest research on barrel cortex, a region of somatosensory and motor corticies in the brain, which are used by animals that rely on whiskers for world exploration.
