The animals kill off around one-quarter of the neurons in their somatosensory cortex, perhaps to save energy, and the cells appear to return the following summer.

Looking at the future of neurodegeneration research!

Overactive immune cells identified in a mouse model and in postmortem human brain tissue may offer a potential therapeutic target for cognitive delays associated with the condition, researchers report.

Conversations between the immune and central nervous systems are proving to be essential for the healthy social behavior, learning, and memory.

Some viruses, possibly even SARS-CoV-2, can sneak into the brain through the nose. Recent studies show that microglia are ready for them when they do.

Comparing the brain scans of high-impact rugby players with those of athletes in noncontact sports, such as rowing and swimming, revealed tiny, yet significant, differences in the brain’s white matter.

Patterns of neural activity known as alpha waves, long thought to originate in the thalamus, may actually stem from a different brain region entirely.

Several routes exist for immune cells to communicate with neurons in the central nervous system, though T cells rarely come in direct contact with neural tissue.

Accumulation of the protein was more likely to be found in the brains of people who slept less well years earlier, according to a new study.
