Glossary E

Excitation transfer theory refers to a theory that states that arousal generated from one stimulus can "spill over" and intensify an emotional reaction to a different stimulus.

Excitatory area refers to an area of a receptive field that is associated with excitation. Stimulation of this area causes an increase in the rate of nerve firing.
Excitatory behaviour refers to the underlying motivation that initiates an emotional sequence in the processing of a message, this is from classical conditioning
Excitatory conditioning is defined as conditioning procedure in which the NS is associated with the presentation of a US.

Excitatory postsynaptic potential (EPSP) is defined as graded depolarization of a neuron. It refers to depolarization that increases the probability of the postsynaptic cell to reach its threshold and fire.

Excitatory response refers to the response of a nerve fiber in which the firing rate increases.

Excitatory transmitter is defined as neurotransmitters that cause the inside of a neuron to become more positively charged. Excitatory neurotransmitters increase the probability that an action potential will be generated and are also associated with increases in the rate of nerve firing.

Excitement refers to the first stage of the sexual response cycle, in which an erection occurs in males and vaginal lubrication occurs in females.
