    1. AClassical conditioning is a good model for memory and forgetfulness
    2. BAssociative learning is related to the increased response in the post-synaptic neuron after a few high frequency pre-synaptic stimuli
    3. CInstrumental conditioning can be explained by the balance between different synaptic connections
    4. DA weak synapse will be strengthened if its activation occurs at the same time that the postsynaptic neuron fires

    1. AThe channel is blocked by magnesium ions
    2. BThe channel is blocked by sodium ions
    3. CGlutamate requires the presence of GABA in order to open the channel

    1. ALTD can be produced by high-frequency stimulation of CA1 neurons
    2. BLTD reflects a gradual strengthening of synaptic connections
    3. CLTD is associated with a decrease in the number of AMPA receptors in the postsynaptic neuron

    3. CLearn to adjust behaviour according to its consequences
    4. DExhibit a specific system to detect accurately the location of a stimulus
  8. 8In a conditioned emotional response study, a tone is paired with an electric shock to your hand. After several trials, the tone alone becomes a conditioned stimulus that can elicit fear in you. Which of the following is true of the anatomy of this fear response?
    1. ADamage to the amygdala facilitates emotional responding
    2. BDamage to the lateral nucleus of the amygdala impairs the learning of conditioned associations
