Question 1

The control rats in the context preexposure experiment displayed less fear in the context where they were immediately_______ than they did in the context where they had been _______ before being shocked.

Accepted Answer

The answer of The control rats in the context preexposure...

Question 2

To create a _______ contextual fear memory, Ramirez used optogenetic stimulation to activate the memory of the preexposed context in a context where the mice were shocked.

Accepted Answer

The statement is incomplete and lacks a specific term to fill in the blank, making it impossible to determine its truth value.

Question 3

Wiltgen's laboratory used a genetically engineered mouse that would express _______ when doxycycline was removed from their diet.

Accepted Answer

The answer of Wiltgen's laboratory used a genetically engineered mouse...

Question 4

Wiltgen's laboratory used a neuronal silencer called _______ to inhibit indexing neurons.

Accepted Answer

The answer of Wiltgen's laboratory used a neuronal silencer called...

Question 5

Which statement(s) do(es) not represent a property of the episodic memory system? (Select all that apply.)

Accepted Answer

The statement "It supports motor skills and learning" does not represent a property of the episodic memory system. Episodic memory is primarily involved in conscious recollection of personal experiences and events, and it does not have a direct role in supporting motor skills or learning.

Question 6

Which statement(s) is/are true about the neural system that support episodic memory? (Select all that apply.)

Accepted Answer

All of the statements are true. The hippocampus receives information from all neocortical regions, the subiculum is the primary output from the hippocampus, the entorhinal cortex projects into the hippocampus and receives information from it, and the system features a return loop from the hippocampus back to the sending units.

Question 7

Which statement(s) is/are false according to indexing theory? (Select all that apply.)

Accepted Answer

All the statements A through D are consistent with indexing theory, which posits that the hippocampus plays a crucial role in linking or indexing distributed memory traces in the neocortex. Therefore, none of the statements are false according to indexing theory.

Question 8

The information that is processed through the hippocampus is then projected to _______. (Select all that apply.)

Accepted Answer

The answer of The information that is processed through the...

Question 9

According to indexing theory, _______. (Select all that apply.)

Accepted Answer

The answer of According to indexing theory, _______. (Select all...

Question 10

The context preexposure facilitation effect _______. (Select all that apply.)

Accepted Answer

The answer of The context preexposure facilitation effect _______. (Select...

Question 11

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

Accepted Answer

The hippocampus is crucial for spatial memory and contextual information, such as remembering where an object was experienced.

Question 12

Optogenetics has revealed that _______. (Select all that apply.)

Accepted Answer

Optogenetics allows for the direct activation of specific neurons using light, which can lead to the creation of false memories by activating indexing neurons. Additionally, activating indexing neurons in the hippocampus can lead to the activation of cortical engram neurons, which are involved in memory storage and retrieval.

Quiz 17: The Hippocampus Index and Episodic Memory
