Genetic malfunction of brain astrocytes triggers migraine

Familial hemiplegic migraine type 2 (FHM2) causes a malfunction of astrocytes in the cingulate cortex. Manipulating astrocytes in the cingulate cortex reversed the disfunction, preventing an increase in migraine-like symptoms in mice carrying the FHM2 defect.

NMDA receptors may link psychosis and sleep deficits

NMDA receptor hypofunction is involved in the reduction of sleep spindles and delta oscillations, which appear in the brain during deep natural sleep. Findings confirm the role NMDA receptors play in sleep disorders that accompany psychotic states.

Ketamine isn’t an opioid and treats depression in a unique way

A new study clarifies the mechanism behind how ketamine works as an antidepressant. Researchers say there is evidence to suggest ketamine binds to NMDA receptors, instead of opioid receptors. Reducing the belief that ketamine is an opioid may make patients with depression more open to using the treatment.

Brain on Fire: Puzzling brain disease could now be better diagnosed and treated

A rare autoimmune disorder popularized by the autobiography and movie "Brain on Fire" is triggered by an attack on NMDA receptors. The disease occurs when antibodies attack NMDA receptors in the brain, leading to memory loss, intellectual changes, seizures, and death.

Microglia, cells thought restricted to central nervous system, are redefined in new study

In response to injury, microglia cross the spinal boundary from the central nervous system to the peripheral nervous system. While in the PNS, microglia provide the function of clearing cellular debris at the point of injury, then return to the CNS in an altered state. Researchers propose this could account for some damage associated with neurodegenerative diseases.
