Q

What are the three main structures and functions of said structures for the limbic system?

A

The amygdala-Emotions(fear)…..The Hippocampus-Memory….The Hypothalamus-Homeostatis

2
Q

True or false: the Limbic system is closely connected to the olfactory system?

A

True

3
Q

How is the limbic system helping me study right now? :)

A

It sets the level of arousal, involved in stimulating and reinforcing behaviors…LIKE DOMINATING THIS EXAM

4
Q

Which structure is a primary output for the limbic system?

A

The hypothalamus

5
Q

A

The Dentate Gyrus and the Cornu Ammonis (CA 1-4)

6
Q

What structure helps the hippocampus send out information?

A

Via the fornix

7
Q

What are the main emotional coordinations of the amygdala?

A

Fear and anxiety

8
Q

What structure am I going to use to control my emotions?

A

The Limbic Association Cortex!

9
Q

What is a fornix circuit that plays a role in cognitive activities, emotional experience, and expression?

A

The Circuit of Papez

10
Q

What is the Circuit of Papez?

A

Parahippocampal Gyrus–>Hippocampus–>fornix–>mammillary body–>thalamus–>cingulate gyrus–>parahippocampal gyrus

11
Q

What does the Stria Terminalis connect? What does it help me do for exams?

A

The Stria Terminalis connects the Amygdala with the hypothalamus and the SEPTAL nuclei for ASSOCIATIVE LEARNING (connecting emotion to homeostasis)

12
Q

Which pathway connects the basal ganglia, olfactory cortex, cingulate gyrus, prefrontal cortex, hypothalamus, and septal nuclei? What does it do?

A

The AmygdaloFUGAL Pathway…Same as Stria Terminalis, associative learning

13
Q

What circuit connects the hypothalamus, amygdala, nucleus accumbens, ventral segmental area, olfactory complex, and prefrontal cortex?

A

The Medial Forebrain Bundle

14
Q

What is the function of the Medial Forebrain Bundle?

A

A Reward Pathway

15
Q

What are some major results of damage to the limbic system?

A

Memory Loss, Smell Dysfunction, Emotional Disturbance, Sexual Behavior, Personality Change

16
Q

Would seizures result in limbic damage?

A

yes
