During brain development, neurons can regulate their movement until they reach their final destination thanks to a "molecular switch" involving the protein Teneurin 4 (Ten4).

Every stroke begins with a sudden interruption of blood flow in the brain. But what happens afterward—why neurons continue to ...

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 ...

Medically reviewed by Nicholas R. Metrus, MD Key Takeaways Neurons are cells that transmit electrical signals through the nervous system.Motor neurons control muscle activity and movement by carrying ...

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 ...

For decades, depression has been explained to patients as a “chemical imbalance” in the brain, a vague phrase that never ...

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 ...

A new study is illuminating how “forever chemicals” can alter our brain cells by impairing the genes that maintain healthy neurons, the cells of our nervous system. Scientists are only beginning to ...
