Questão 1
Questão
According to Hebb's rule...
Responda
-
Classical conditioning is a good model for memory and forgetfulness
-
Associative learning is related to the increased response in the post-synaptic neuron after a few high frequency pre-synaptic stimuli
-
Instrumental conditioning can be explained by the balance between different synaptic connections
-
A weak synapse will be strengthened if its activation occurs at the same time that the postsynaptic neuron fires
Questão 2
Questão
The preforant pathway of the entorhinal cortex...
Responda
-
Interconnects the CA1 and CA3 fields within the hippocampus
-
Is another name for the fornix
-
Interconnects the granule cells ofthe dentate gyrus with the amygdala
-
Leads to the dentate gyrus within the hippocampal formation
Questão 3
Questão
Receptors for which of the following neurotransmitters are usually involved in long-term potentiation?
Responda
-
Serotonin
-
Dopamine
-
Glutamate
-
GABA
Questão 4
Questão
What normally prevents the calcium channel of the NMDA receptor from opening in response to glutamate only?
Responda
-
The channel is blocked by magnesium ions
-
The channel is blocked by sodium ions
-
Glutamate requires the presence of GABA in order to open the channel
-
Glutamate requires the presence of glycine in order to open the channel
Questão 5
Questão
The induction of long-term potentiation in the hippocampus would be blocked by...
Responda
-
A drug such as AP5 that blocks NMDA receptors
-
Using high-frequency pulses
-
A drug that activates NMDA receptors
-
Injection into the postsynaptic cell of a drug that activates calcium ions
Questão 6
Questão
Which of the following is true of long-term depression (LTD)?
Responda
-
LTD can be produced by high-frequency stimulation of CA1 neurons
-
LTD reflects a gradual strengthening of synaptic connections
-
LTD is associated with a decrease in the number of AMPA receptors in the postsynaptic neuron
-
LTD is associated with an increase in the number of AMPA receptors in the postsynaptic neuron
Questão 7
Questão
The primary function of perceptual learning is to...
Responda
-
Identify and categorise objects
-
Make an association between two stimuli
-
Learn to adjust behaviour according to its consequences
-
Exhibit a specific system to detect accurately the location of a stimulus
Questão 8
Questão
In 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?
Responda
-
Damage to the amygdala facilitates emotional responding
-
Damage to the lateral nucleus of the amygdala impairs the learning of conditioned associations
-
Damage to the visual association cortex would prevent the learning of the conditioned associations in this instance
-
Damage to the lateral nucleus of the pre-frontal cortex impairs the learning of conditioned associations
Questão 9
Questão
Which of the following is NOT true of instrumental (operant) conditioning?
Responda
-
It involves a simple association between two stimuli
-
It involves learning the relationship between a response to a stimulus and a reward
-
It permits an organism to adjust its behaviour according to the consequences of that behaviour
-
Either punishment or reward can reinforce it
Questão 10
Questão
An instrumental (operatn) response that produces a favourable consequence...
Responda
-
Will be immediately suppressed
-
Will occur more frequently
-
Weakens adjacent circuits in the brain
-
Is an important component of perceptual learning
Questão 11
Questão
Damage to which of the following structures would be expected to impair instrumental (operant) conditioning?
Responda
-
Amygdala
-
Hypothalamus
-
Basal ganglia
-
Frontal cortex
Questão 12
Questão
An example of a natural reinforcer is...
Responda
-
Cocaine
-
Amphetamine
-
Dopamine
-
Food for a hungry person
Questão 13
Questão
Which of the following is important for the acquisition of complex behaviours?
Responda
-
The behaviour must result in long-term depression of the basal ganglia
-
As the person becomes more proficient in the new behaviour, the transcortical circuits become more active
-
As a person becomes more proficient in the behaviour, the control of the process is transferred to the basal ganglia
-
As a person becomes more proficient in the behaviour, the control of the process is transferred to the transcortical pathways
Questão 14
Questão
A person with amnesia due to Korsakoff's syndrome is most likely to have severe damage in the...
Responda
-
Hippocampus
-
Fornix
-
Mammillary bodies
-
Cingulate gyrus
Questão 15
Questão
One striking aspect of patient H.M.'s deficit was that he...
Responda
-
Could learn some new tasks but was unaware of having learned them
-
Reversed word order in repeated sentences
-
Indicated that he remembered things he had never seen
-
Only remembered recent facts
