Electrical and chemical signalling enable plants to perceive environmental stimuli and coordinate systemic responses. Membrane potential changes such as action potentials and variation potentials ...
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 ...
In frog brains (orange-blue), developing axons from the eye (yellow-white) follow a specific path to reach their final destination. Along the way, they make a characteristic turn. This turning is ...
