Question Description
Need help with my Psychology question – I’m studying for my class.
QUESTION 1
- Emotional modulation of memory formation has been shown to be mediated by the:

B.Amygdala
C.Septum
D.Hippocampal formation
QUESTION 2
- Bilateral damage to the medial temporal lobes may lead to severe:
A.Retrograde amnesia
B.Episodic amnesia
C.Prosopagnosia
D.Anterograde amnesia
QUESTION 3
- In the hippocampus, commissural fibers carry information from the:
A.Cerebellum
B.Entorhinal cortex
C.Other hippocampus
D.Subiculum
QUESTION 4
- According to Hebb’s notion of cell assemblies, information can be stored by groups of neurons that are:
A.Activated simultaneously or in close succession
B.Located in the same region of the brain
C.Negatively charged
D.All of the above
QUESTION 5
- The amygdala is directly involved in:
A.Spatial location learning
B.Skill learning
C.Fear conditioning
D.Eye-lid conditioning
Answer:
QUESTION 1 Emotional modulation of memory formation has been shown to be mediated by the: B. Amygdala
The amygdala is a key structure in the brain that plays a crucial role in processing emotions, especially fear and anxiety. It has been shown to influence memory formation, particularly in relation to emotional or emotionally charged events.
QUESTION 2 Bilateral damage to the medial temporal lobes may lead to severe: D. Anterograde amnesia
The medial temporal lobes, especially the hippocampus, play a crucial role in memory formation and consolidation. Damage to both medial temporal lobes can result in anterograde amnesia, which is the inability to form new memories after the damage occurs.
QUESTION 3 In the hippocampus, commissural fibers carry information from the: C. Other hippocampus
Commissural fibers in the hippocampus connect the two hemispheres of the brain and allow for communication and information transfer between the two hippocampal structures.
QUESTION 4 According to Hebb’s notion of cell assemblies, information can be stored by groups of neurons that are: A. Activated simultaneously or in close succession
Hebb’s theory of cell assemblies suggests that when groups of neurons are activated simultaneously or in close succession, their connections strengthen, leading to the storage of information in the brain.
QUESTION 5 The amygdala is directly involved in: C. Fear conditioning
The amygdala is directly involved in the processing and regulation of emotions, particularly fear. Fear conditioning, which is the learning of fear responses to specific stimuli, involves the amygdala as a critical component of the fear circuit in the brain.
