Scientists Discover Why Lack of Sleep Worsens Migraine Symptoms

For the first time, researchers have studied what happens in the brains of people who have migraines when they haven’t slept enough. They found differences in how the cerebral cortex suppresses pain in people with migraine after sleep deprivation.

Cocaine Activates Neurons Through Reelin

Researchers have discovered that the glycoprotein reelin is a marker for cocaine-activated neurons in the nucleus accumbens. Reelin plays a key role in cocaine-related gene expression, neuron excitability and behavior changes.

Stabilized, Not Shut Down: What Ketamine Really Does to the Brain

Research reveals that ketamine stabilizes brain activity in a dose-dependent way. The study used high-density EEG to track changes in brain stability, suggesting ketamine’s effects on brain dynamics might be central to its therapeutic use.
