Exam 12: Memory Modulation Systems

What is the connection between epinephrine, the flight-or-fight response, and memory modulation?

Epinephrine is not found in neurons.

The phosphorylation of _______ is impaired in old rats.

One reason the basolateral region of the amygdala (BLA) is believed to be the primary mediator of epinephrine's influence on memory is because it has many anatomical connections with other regions of the brain that store memories.

Unlike adrenaline, _______ can directly enter the brain.

Inhibiting the output of the locus coeruleus will interfere with memory storage because no epinephrine will be released by the adrenal gland.

Old rats are significantly impaired when the retention interval is seven days. Explain why. Is this impairment reversible?

The amygdala consists of many subnuclei, but only neurons in the BLA are critical for memory modulation.

Norepinephrine is released by the _______, into the _______.

The adrenal hormone epinephrine has been shown to _______. (Select all that apply.)

What were the results of experiments in which lidocaine or clenbuterol were injected into the BLA?

Which statement(s) is/are true? (Select all that apply.)

When a beta-adrenergic agonist such as clenbuterol is injected into the BLA following avoidance training, _______. (Select all that apply.)

How was strychnine, a lethal poison, used to study memory modulation?

Old rats show enhance phosphorylated CREB.

If propranolol is injected into the amygdala following a place-learning task, the rat's memory for the platform location will be impaired.

The flow of energy in cells is called _______.

The strength of the memory trace can be modified for up to ten hours after its formation.

Glucose but not epinephrine can cross the blood-brain barrier.

McGaugh used strychnine to inhibit memory modulation.
