Cortex: the outer layers of the brain in humans and other mammals. Axon: a fibre that extends from a neuron and transmits electrochemical impulses from that neuron to the dendrites of other neurons. Dendrite: a fibre that extends from a neuron and receives electrochemical impulses transmitted from other neurons via their axons. Synapse: the intersection between the axon of one neuron and the dendrites of other neurons. Neurotransmitter: a brain chemical that carries information from the axon of a sending neuron to the dendrites of a receiving neuron.
