Flashcards in Limbic System-Exam II Deck (16):
1

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

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

2

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

True

3

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

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

4

Which structure is a primary output for the limbic system?

The hypothalamus

5

What are the two main parts of the hippocampus? Think teeth and utah baseball player.

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

6

What structure helps the hippocampus send out information?

Via the fornix

7

What are the main emotional coordinations of the amygdala?

Fear and anxiety

8

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

The Limbic Association Cortex!

9

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

The Circuit of Papez

10

What is the Circuit of Papez?

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

11

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

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

12

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

The AmygdaloFUGAL Pathway...Same as Stria Terminalis, associative learning

13

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

The Medial Forebrain Bundle

14

What is the function of the Medial Forebrain Bundle?

A Reward Pathway

15

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

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

16

Would seizures result in limbic damage?

yes
