A branch of psychology concerned with the links between biology and behavior.
A nerve cell; the basic building block of the nervous system.
The bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body.
The extension of a neuron, ending in branching terminal fibers, which messages pass to other neurons or to muscles or glands.
A layer of fatty tissue segmentally encasing the fibers of many neurons
A neural impulse; a brief electrical charge that travels down an axon. The axon potential is generated by the movement of positively charged atoms in and out of channels in the axons membranes.
The level of stimulation required to trigger a neural impulse.
The junction between the axon tip of the sending neuron and the dendrite of the cell body of the receiving neuron.
Chemical messengers that traverse the synaptic gaps between neurons. When released
A neurotransmitter that enables learning and memory and also triggers muscle contraction.
Natural, opiate like neurotransmitters linked to pain control and to pleasure.
