Q

Inferior Frontal Gyrus

A

Frontal Lobe

Made of the Pars Opercularis/Pars Triangularis. Broca’s area is made of up of these two ‘Pars’, if injured broca’s aphasia occurs and the person can’t talk, where mouth movements are.

Q

Wernicke’s Area: What two gyri?

A

Parietal Lobe

Supramarginal gyrus and angular gyrus.
What happens if this is messed up? Wernicke’s Aphasia: you can talk, but no logical sense and you can’t understand anything

20
Q

Precuneus

A

Parietal Lobe

Processing of polymodal information (multiple sensory information, where it all comes together)

21
Q

What two sulcus’ bound the temporal lobe?

A

Lateral (sylvian) sulcus and collateral sulcus on ventral surface

22
Q

Superior temporal gyrus

A

Temporal lobe

audiotry information. Within this gyrus, hippocampus/amygdala

23
Q

Medial Temporal Gyrus

A

Temporal Lobe

Spatial Information

24
Q

Collateral/Parahippocampal Gyrus

A

Divided Temporal from limbic lobe

25
Q

Occipitotemporal gyri

A

Temporal Lobe

26
Q

Cuneus

A

Occipital Lobe

Visual Infomation

27
Q

Calcarine Sulcus

A

Separates cuneus from lingual gyrus

28
Q

Uncus

A

Little notch in the limbic system

29
Q

Insular Lobe

A

Remove the overlying parietal and temporal lobe and split sulcus open. Insular cortex lies internally. Associated with gustatory/taste info, also linked with addiction and motivational behaviors

30
Q

Association Fibers

A

White Matter that connects various areas of the cortex within the same hemisphere

31
Q

Cingulum

A

Association fiber.

Frontal -> Parietal —> occipital. Wraps around corpus callosum

32
Q

Longitudinal Fasciculus

A

Association Fiber

Superior (lateral) and inferior (ventral of temporal lobe)

33
Q

Uncinate

A

Association Fiber

Prefrontal to temporal lobe, more rostral parts

34
Q

Arcuate Fasciculus

A

Association Fiber

Fronto-temporal connections

35
Q

Comissural Fibers

A

Cross hemispheres, includes corpus callosum

36
Q

Anterior Commissure (medial surface)

A

Commisural Fibers

Connects frontal and temporal lobes

37
Q

Hippocampal Commissure (medial surface)

A

Commisural Fibers

Connects hippocampal fibers from either side

38
Q

Projection Fibers

A

Connects Lower parts of the brain and the spinal cords

39
Q

Internal Capsule

A

Project Fibers

40
Q

Where is the corpus striatum?

A

Basal Nuclei (Ganglia)

41
Q

Neostriatum

A

Located in Basal Ganglia

Made of caudate nucleus and putamen

42
Q

Putamen

A

Located in Basal Ganglia

Lateral to Thalamus

43
Q

Paleostriatum

A

Located in Basal Ganglia

Globus pallidus - more internal

Hippocampus parts

A

Parahippocampus gyrus, subiculum, dentate gyrus, hippocampus proper

Fornix: major output path that wraps around corpus callosum

47
