Inhibitory postsynaptic potential (IPSP) is the presence of an ionic current flow that hyperpolarizes the postsynaptic neuron. As a result, a greater depolarization than normal is required for excitation and there is only a small probability that there will be an action potential; temporary hyperpolarization of a membrane
Inhibitory transmitter refers to neurotransmitters that cause the inside of a neuron to become negatively charged. Inhibitory transmitters decrease the probability that an action potential will be generated and are also associated with decreases in the rate of nerve firing.
Inhibitory-center-excitatorysurround receptive field refers to a center-surround receptive field in which stimulation of the center causes an inhibitory response and stimulation of the surround causes an excitatory response.
Initial contact information generally includes data obtained prior to the first interview as well as in-take materials. Typically included are such items as information on record, in-take data, psychological testing results, and the in-take summary.
Initial phase when diagnosis of depression is made. Referral may be made if interpersonal therapy is not appropriate. Assessment is focused on placing the problem into one or more of the four (4) problem areas. Diagnosis is shared with the patient. Encouragement and hope for the problem are given to the patient.
