Flashcards in 04 Limbic System Deck (24):
1

Rim of phylogenetically primitive cortex around the brainstem

Limbic lobe

2

Medial part of the brain, limited above by the cingulate sulcus and below by the corpus callosum, partially encircles the corpus callosum

Cingulate gyrus

3

Closely related to the amygdala
Involved in error and conflict detection

Anterior cingulate cortex

4

Closely related to the hippocampus
May be involved in the capacity to understand other people's beliefs

Posterior cingulate gyrus

5

Necessary in distinguishing reality from fantasy

Paracingulate sulcus

6

Thin layer of gray matter in contact with the dorsal aspect of the corpus callosum

Induism griseum (supracallosal gyrus)

7

The most medial portion of temporal lobe
Memory resides here
Anterior and inferior continuation of the cingulated gyrus

Parahippocampal gyrus

8

Part of the parahippocampal gyrus that contains cell bodies and axons that are continuous with different parts of the brain

Parahippocampal cortex

9

The cortex covering he anterior part of the parahippocampal gyrus, near the uncus
Receives input from the amygdala, the olfactory bulb, limbic lobe and other cortical association areas

Entorhinal cortex

10

A sulcus demarcating the lateral boundary of the uncus on the medial aspect of the temporal lobe

Reinaldo sulcus

11

Cortical region in the medial temporal lobe involved in both visual perception and memory
Facilitated the recognition and identification of environmental stimuli

Perirhinal cortex

12

Consolidation of new declarative memories
Plays a role in memory, spatial navigation, and control of attention

Hippocampus

13

Almond-shaped nucleus in the medial temporal bone
Plays a role in the processing and memory of emotional reactions, as well as smell, psychopathic states, phobias, and even binge drinking

Amygdala

14

Continuous with the parahippocampal gyrus and the white matter within is the cingulum

Cingulate cortex

15

Connects the amygdala with the thalamus
Runs along the ventricular surface of the thalamus
Associated with anxiety and gender identity

Stria terminalis

16

Carries fibers from the hippocampus to the septal nuclei and the mammillary bodies

Fornix

17

Carries fibers from the amygdala to the hypothalamus, thalamus, the basal forebrain, the brainstem, septal nuclei and nucleus accumbens

Ventral amygdalofugal pathway

18

Carries information to and from the ventral tegmentum of the brainstem and the nucleus accumbens
Parts of the system of reward and pleasure

Medial forebrain bundle

19

Carries ascending visceral signals from the reticular formation and descending hypothalamic axons

Dorsal longitudinal fasciculus

20

Pleasure zone

Septal nuclei

21

One of the five major nuclei of the basal ganglia
Most inferior part of the striatum with predominantly limbic connections

Nucleus accumbens

22

Eating behaviors in the hypothalamic nuclei

Paraventricular nuclei
Supraoptic nuclei

23

Reproductive behaviors in the hypothalamic nuclei

Medial preoptic nuclei
Ventromedial nuclei

24

Defensive behaviors in the hypothalamic nuclei

Anterior nuclei
Ventromedial nuclei
