The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood flow, sense physical forces and keep vessel walls intact. Scientists have ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

Activity-dependent changes in synaptic strength are widely recognized as the cellular foundation of information processing in the nervous system. Precise spatiotemporal regulation of intracellular ...

Calcium is widely known for its role in maintaining strong bones and teeth, but it is also one of the body's most important cellular messengers. Calcium signals help regulate muscle contraction, ...
