The brain contains many cell types, from the prominent neurons to the lesser-known microglia. The latter are integral to the brain's immune system and play a crucial role as the brain's cleanup crew.

A clearance mechanism involving microglia has been known to relieve neurons of toxic protein aggregates such as those associated with Alzheimer’s disease and Parkinson’s disease. Unfortunately, this ...

A study conducted at the lab of Beth Stevens, Ph.D., at Boston Children's Hospital, has revealed that an immune protein impacts neuronal protein synthesis in the aging brain. Previous work from the ...

While tics have been considered to result from an aberrant function of the brain's motor cortex, a Kobe University mouse ...

A new Yale study has revealed that neurons — the energy-hungry cells that connect and direct activity in the brain — are equipped with “backup batteries” that kick in to keep the brain running during ...

When triggered by an odor, rapid changes in membrane voltage and intracellular calcium ion levels occur in nematode olfactory neurons, causing membrane voltage sensors and calcium ion sensors to ...

Researchers have unveiled two major neuroscience advances: Salk Institute scientists reduced seizures in Fragile X syndrome mice by suppressing a protein pathway in astrocytes, while separate teams in ...

Neurodiversity advocates have long argued that autistic brains are differently wired. Now, new evidence shows they are right. Researchers have found atypical numbers of brain cells in two key areas of ...

Scientists have shown that specialized cells involved in how the body responds to insulin are activated in the brain after exercise, suggesting that physical activity may directly improve brain ...
