Exam 13: The Yin and Yang of Memory: Forgetting Versus Maintenance

Interference theories of forgetting assume that a second learning event could produce amnesia for a prior experience by interfering with the consolidation of the first event, provided the second event was similar to the first and occurred shortly after it.

PKMζ can enhance already established memories.

GluR23y prevents forgetting by inhibiting the exocytic removal of _______.

The consolidation period ends when the memory trace is no longer vulnerable to the disruption of transcription and translation processes.

Why does GluR23y prevent forgetting?

Memory retention can be enhanced by _______. (Select all that apply.)

Social isolation enhances _______ activity.

If forgetting is due to intrinsically active neural processes, then _______. (Select all that apply.)

The peptide GluR23y enhances the removal NMDA receptors from the PSD.

Which do(es) not require PKMζ? (Select all that apply.)

PKMζ may have evolved to prevent forgetting.

_______ NMDA receptor function during the retention interval prevents forgetting.

Forgetting, according to most psychologists, is the result of _______. (Select all that apply.)

From the perspective of the brain, processes that produce _______ may have evolved to help maintain the balance of excitatory and inhibitory inputs on a neuron.

According the results obtained by Migues et al., forgetting can be prevented if the endocytic removal of AMPA receptors is inhibited.

Why does PKMζ decrease the rate of forgetting?

According to the Hardt-Migues experiments, _______. (Select all that apply.)

Inhibition of either NMDA receptors or voltage-dependent calcium channels (vdCCs) can prevent the forgetting of an object-location memory.

Inhibiting NMDA receptor function during the retention interval can prevent forgetting.

The consolidation period ends when the memory trace is no longer vulnerable to the disruption of ZIP.
