Classical Condition

Physiology of Behavior Ch 13 Neurology

QuestionAnswer
The ____ is part of an important system involved in a particular form of stimulus-response learning: classically conditioned emotional responses. amygdala
An aversive stimulus produces a bahavioral, autonomic, and hormonal response.
LeDoux, Sakaguchi, and Reis found that a conditioned emotional response can occur in the absence of the auditory cortex.
If a tone is pared with the painful stimulus the weak synapses in the lateral amygdala are stregthened through the action of the Hebb rule.
Quirk, Repa, and LeDoux found evidence for the synaptic changes in the lateral nucleus of the amygdala.
Synaptic changes in the lateral nucleus of the amygdala experiment involved recording activity of neurons before during and after pairing a tone with a foot shock.
Firing rate of neurons in the lateral amygdala increase during conditioning.
Firing rate of neurons in the lateral amygdala decrease during extinction.
Changes in the lateral amygdala reosible for acquisition of a conditioned emotional response involve LTP.
The amygdala follows the Hebbian Rule.
Synapse strengthening by pariing of CS and US happens in the lateral nucleus of the amygdala.
Conditioned emotional responses take place in the hypothalamus, midbrain, pons, and medulla.
The lateral nucleus outputs to the basal nucleus, accessory basal nucleus, and the central nucleus.
The basal nucleus outputs to the central nucleus.
The accessory basal nucleus out puts to the central nucleus.
The central nucleus outputs to several places including the hypothalamus, midbrain, pons, and medulla causing a conditioned emotional response.
LTP in many parts of the brain is accomplished through the activation of NMDA receptors.
NMDA receports also participate in the synaptic plasticity that occurs in the amygdala.
Learning causes AMPA receptors to be driven in to dendritic spines of synapses between lateral amygdala neurons and axons that provide auditory input.
Rodrigues used a drug that prevents the autophosphorylation of CaM-KII.
Collins and Pare found that differential conditioning may produce both long term potentiation and long term depression in the lateral amygdala.
Experiment: showing the differential conditioning may produce both LTP and LTD Electrical recordings of the activity of single neurons in the lateral amygdala showed that after learning had taken place, the CS+ elicited a larger response, white the CS- showed a smaller response.
Schafe and LeDoux LTP is essential for stimulus response learning.
Anisomycin prevents long lasting LTP by disrupting protein synthesis.
Anisomycin also blocks long term retention of a conditioned emotional response when it is injected into the lateral amygdala.
Protein synthesis is necessary for long-lasting LTP
