Chapter Twenty-five Molecular Mechanisms of Learning and
Memory
1. Which is the process by which some experiences, held temporarily by transient
modifications of neurons, are selected for permanent storage in long-term
memory? Choose the correct option.
A) Stimulus selectivity
B) Memory consolidation
C) Distributed memory storage
D) Autophosphorylation


2. What happens to a memory if some neurons in the neural network storing that memory
begin dying? Choose the correct option.
A) Catastrophic loss
B) Retrograde amnesia
C) Graceful degradation
D) Anterograde amnesia


3. At what synapse does habituation to gill-withdrawal reflex occur in Aplysi? Choose
the correct option.
A) Synapse at the sensory nerve endings in the skin
B) Synapse on the abdominal muscle
C) Synapse joining the sensory neuron and motor neuron
D) Synapse between L29 from the head and the sensory neuron


4. Which of the following provide synaptic input to the Purkinje cell dendrites of
the cerebellum? Choose the correct option.
A) Climbing fibers from the superior olive
B) Parallel fibers from neocortical pyramidal neurons
C) Climbing fibers from the inferior olive and parallel fibers from cerebellar
granule cells
D) Mossy fibers from the pontine nuclei


5. Which term refers to the concept that the rules of synaptic plasticity change
depending on the history of synaptic or cellular activity? Choose the correct option.
A) Synaptic stability
B) Homeostasis
C) Metaplasticity
D) Denervation supersensitivity
