  • 2. 

    Implicit memory is another name for nondeclarative memory.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Implicit memory refers to the type of memory that is not consciously recalled and is typically acquired through repetition or practice. It includes skills, habits, and conditioned responses. Nondeclarative memory is a term used to describe memory that is not easily put into words or consciously expressed. Implicit memory and nondeclarative memory are essentially synonymous, both referring to memory that is not consciously accessible. Therefore, the statement that "Implicit memory is another name for nondeclarative memory" is true.

    Receptors for ____________ are involved in LTP.

    • Dopamine

    • Glutamate

    • Acetylcholine

    • Serotonin

    • GABA

    Correct Answer
    A. Glutamate
    Explanation
    Glutamate receptors are involved in Long-Term Potentiation (LTP), a process that strengthens the synapses between neurons and is considered a cellular mechanism for learning and memory. Glutamate is the primary excitatory neurotransmitter in the brain, and its receptors play a crucial role in synaptic plasticity, including LTP. Therefore, the correct answer is glutamate.

    Patient H.M. shows deficits in motor learning, perceptual learning, and stimulus-response learning.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because Patient H.M. actually did not show deficits in motor learning, perceptual learning, and stimulus-response learning. In fact, he had intact motor skills and was able to learn new motor tasks. However, he did have severe anterograde amnesia, which affected his ability to form new long-term memories. This means that while he could learn new skills in the moment, he would not remember them later.

    Which of the following is true of learning?

    • Learning and Memory are synonymous.

    • Memories are related to the electrical activity of the brain.

    • Learning involves modification of the nervous system by experiences.

    • Experiences are stored in the brain, in seperate folders, like that of a file cabinet.

    • Learning is possible in the absence of memory.

    Correct Answer
    A. Learning involves modification of the nervous system by experiences.
    Explanation
    Learning involves modification of the nervous system by experiences. This means that when we learn something, our brain undergoes changes in its structure and function as a result of the experiences we have. These modifications can include the formation of new neural connections, strengthening of existing connections, and changes in the release of neurotransmitters. This process allows us to acquire new knowledge and skills and adapt to our environment.

    The NMDA receptor controls the activity of a sodium channel.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The NMDA receptor is a type of glutamate receptor that controls the activity of a calcium channel, not a sodium channel. When activated, the NMDA receptor allows calcium ions to enter the cell, which plays a crucial role in synaptic plasticity and learning. Therefore, the correct answer is False.

    The ________ states that a weak synapse will be strengthened if its activation occurs at the same time that the postsynaptic neuron fires.

    • All-or-none principle

    • Law of effect

    • Perforant path hypothesis

    • Hebb rule

    • Law of summation

    Correct Answer
    A. Hebb rule
    Explanation
    The Hebb rule states that a weak synapse will be strengthened if its activation occurs at the same time that the postsynaptic neuron fires. This rule is based on the idea that when two neurons are repeatedly activated together, the connection between them is strengthened, leading to enhanced communication. This principle is fundamental to understanding how synaptic plasticity and learning occur in the brain.

  • 8. 

    The increase in synaptic strength that occurs in LTP is due to a modification of the synapse to include

    • More postsynaptic NMDA receptors

    • More postsynaptic AMPA receptors

    • Fewer synaptic connections

    • More postsynaptic GABA contacts

    • Fewer presynaptic GABA contacts

    Correct Answer
    A. More postsynaptic AMPA receptors
    Explanation
    In long-term potentiation (LTP), the increase in synaptic strength is attributed to a modification of the synapse that involves the incorporation of more postsynaptic AMPA receptors. AMPA receptors are ion channels that mediate the majority of fast excitatory neurotransmission in the central nervous system. By increasing the number of AMPA receptors, the synapse becomes more responsive to neurotransmitter release, resulting in enhanced synaptic transmission and strengthening of the connection between neurons. This modification is believed to underlie the cellular basis of learning and memory.

    Relational learning involves changes in

    • Connections between different regions of the sensory association cortex.

    • A motor system.

    • Connections between a sensory system and a motor system.

    • A single sensory system.

    • Contingencies between a response and a subsequent stimulus.

    Correct Answer
    A. Connections between different regions of the sensory association cortex.
    Explanation
    Relational learning refers to the process of making connections between different regions of the sensory association cortex. This means that when we engage in relational learning, we are forming associations and connections between different parts of the brain that are responsible for processing sensory information. This allows us to integrate and understand various sensory inputs, such as sight, sound, and touch, in a meaningful way. By forming these connections, we are able to make sense of our environment and learn how different stimuli are related to each other.

    In classical conditioning, an organism

    • Is able to recognize objects by the sounds they make.

    • Identifies and categorizes objects.

    • Shows a species-typical behavior in response to a previously unimportant stimulus.

    • Learns the consequences of a specific behavior.

    • Forms an association between a response and a stimulus.

    Correct Answer
    A. Shows a species-typical behavior in response to a previously unimportant stimulus.
    Explanation
    Classical conditioning is a type of learning in which an organism learns to associate a previously neutral stimulus with a meaningful stimulus. In this process, the organism develops a response to the previously unimportant stimulus, which is known as a conditioned response. Therefore, the answer "shows a species-typical behavior in response to a previously unimportant stimulus" is the correct explanation as it accurately describes the concept of classical conditioning.

    Which of the following is a strong candidate to act as a retrograde messenger from the dendrite to the terminal button?

    • Glutamate.

    • Nitric oxide.

    • Nitrous oxide.

    • Norepinephrine.

    • NMDA.

    Correct Answer
    A. Nitric oxide.
    Explanation
    Nitric oxide is a strong candidate to act as a retrograde messenger from the dendrite to the terminal button. Nitric oxide is a gas that can diffuse freely across cell membranes, allowing it to travel from the dendrite to the terminal button. It is involved in various physiological processes, including synaptic plasticity and long-term potentiation, and can regulate neurotransmitter release. Its ability to act as a retrograde messenger makes it an important molecule in intercellular communication within the nervous system.

    Which of the following is true of LTP?

    • LTP is the cellular basis for episodic memory.

    • LTP occurs independently of synaptic activity.

    • LTP reflects a persistent temporal summation of postsynaptic potentials.

    • LTP can be produced in isolated hippocampal slices.

    • LTP typically lasts up to one hour.

    Correct Answer
    A. LTP can be produced in isolated hippocampal slices.
    Explanation
    LTP (Long-Term Potentiation) refers to the strengthening of synapses, which is believed to be a cellular mechanism underlying learning and memory. The given answer states that LTP can be produced in isolated hippocampal slices. This means that LTP can be induced and observed in laboratory settings by isolating and studying hippocampal tissue. This is a known fact in the field of neuroscience and has been extensively studied to understand the mechanisms of synaptic plasticity and memory formation.
