For this reason, electrical synapses work faster than chemical ones and allow for impulses to travel in either direction within the neuron. However, because they don’t use neurotransmitters, ...

Contrary to previous assumptions, nerve cells in the human neocortex ... The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops.

Receptor in the skin detects a stimulus (the change in temperature). Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS. Relay neurons ...
