Calcium in neuroscience

Calcium is a vital mineral involved in nerve function, acting as a key signaling molecule within neurons. When a nerve signal reaches a neuron’s end, calcium ions flow into the cell through special channels. This influx triggers the release of neurotransmitters—chemical messengers that carry signals across synapses to other neurons. Additionally, calcium helps regulate neuron growth, strength, and communication. Proper calcium levels are essential for normal brain activity, learning, and memory. Disruptions in calcium signaling can contribute to neurological disorders, making it a crucial component for healthy nervous system functioning.
