21
Q

A

Neocortex; cerebral cortex

22
Q

“Inner room;” “inner chamber;” “gateway to the cortex”) major relay station from the sensory systems of the body to the cortex; almost all messages entering the cortex come through this

A

Thalamus

23
Q

The fiber neurons that connects the left and right cerebral hemispheres

A

Corpus callosum

24
Q

An internal brain structure, just internal to the temporal lobes, strongly implicated in the storing of new information into long-term memory

A

Hippocampus

25
Q

An almond-shaped structure adjacent to one end of the hippocampus, often involved in emotion processing

A

Amygdala

26
Q

(Of the brain) frontal, parietal, occipital, and temporal

Lobes

27
Q

Most forward part of the cortex, and important for the control of thought and action

A

Frontal lobe

28
Q

Portion of the cortex on the top, behind the frontal lobe and in front of the occipital lobe. This part of the cortex is important for sensory processing, spatial processing, and working memory

A

Parietal lobe

29
Q

Lobe at the back of the brain that is most heavily involved in vision

A

Occipital lobe

30
Q

Lobe of the cortex on the sides, below the frontal and parietal lobes. This lobe is important for audition and memory

A

Temporal lobe

31
Q

Numbered areas of the cortex that were identified by an analysis of physical differences in different parts of the brain. Useful in locating general ideas of the cortex

A

Brodmann’s areas

32
Q

(Left and right) the two major structures in the neocortex. In most people, the left cerebral hemisphere is especially responsible for language and other symbolic processing, and the right for nonverbal, perceptual processing

A

Cerebral hemisphere

33
Q

The principle that control of one side of the body is localized in the opposite-side cerebral hemisphere. The fact that the left hand, for instance, is largely under the control of the right cerebral hemisphere illustrates the principle of _________.

A

Contralaterality

34
Q

The principle that each cerebral hemisphere has specialized functions and abilities

A

Hemisphere specialization
