Sensory Neurons Outside the Brain Drive Autistic Social Behaviors

The loss of the protein neurofibromin 1 (NF1) in adult male flies resulted in social impairments. The deficits were traced back to a primary disruption in a small group of peripheral neurons which control external stimuli, including touch and smell, that communicate to the brain. Read More

To Let Neurons Talk, Immune Cells Clear Paths Through Brain’s ‘Scaffolding’

Dropping the level of the IL-33 immune molecule increased the number of synapses in the brain. In older mice, ramping up IL-33 helped push the number of new synapses toward a more youthful state. Read More

How Much Oxygen Does the Brain Need?

Researchers directly measured oxygen levels in an intact brain and correlated it with neural activity. During normal activity, only 50% of oxygen is used for neural activity, the remaining 50% is required for glial cells and maintaining the metabolic rate of other nerve cells. Read More
