Researchers have discovered a critical link between the brain’s waste-clearing system and early neuron degeneration in Alzheimer’s disease. The study shows that the first neurons to die in Alzheimer’s also regulate fluid flow essential for clearing brain toxins.

A new study in mice shows that while brief food smells spark hunger, prolonged exposure makes them eat less. Brain circuits linking smell and appetite explain this effect.

Glutamate is implicated in migraine pathophysiology. NMDA, AMPA, and kainate antagonists, plus approaches that target metabotropic glutamate receptors (mGlu), are evaluated for potential to reduce attacks and symptoms.

Glutamate and GABA in the prefrontal cortex relate to working memory in humans: higher glutamate is associated with better accuracy and higher GABA with less distraction; in older adults, hippocampal glutamate is associated with more interference.
