Question 21

Consists of a number of other interlinked structures that form a border around the brainstem

Includes the olfactory bulb, hypothalamus, hippocampus, amygdala, and cingulate gyrus of the cerebral cortex

Answer 21

The Limbic System

Question 22

A large structure located between the thalamus and cerebral cortex

Toward the posterior portion of the forebrain

Critical for certain types of memory, especially memories for individual events.

Answer 22

small area near the base

Conveys messages to the pituitary gland to alter the release of hormones

Answer 23

Hypothalamus

Question 24

relay station from the sensory organs; main source of input to the cortex

Answer 24

Thalamus

Question 25

Four fluid-filled cavities within the brain’s central canal containing cerebrospinal fluid

Cerebrospinal fluid (CSF): a clear fluid found in the brain and spinal cord

Answer 25

The Ventricles

Question 26

Known as the striate cortex or the primary visual cortex

Highly responsible for visual input

Damage can result in cortical blindness

Located at the posterior end of the cortex

Answer 26

The Occipital Lobe

Question 27

Contains the postcentral gyrus (“primary somatosensory cortex”)
Primary target for touch sensations and information from muscle-stretch receptors and joint receptors

Also responsible for processing and integrating information about eye, head, and body positions from information sent from muscles and joints

Essential for spatial information as well as numerical information

Answer 27

The Parietal Lobe

Question 28

The most prominent part of the mammalian brain. Consists of the cellular layers on the outer surface of the cerebral hemispheres

Divided into two halves

Joined by two bundles of axons called the corpus callosum and the anterior commissure

More highly developed in humans than other species

Answer 28

The Cerebral Cortex

Question 29

Located on the lateral portion of each hemisphere near the temples

Target for auditory information and essential for processing spoken language

Also responsible for complex aspects of vision, including movement and some emotional and motivational behaviors

Klüver-Bucy syndrome associated with temporal lobe damage

Answer 29

The Temporal Lobe

Question 30

Contains the prefrontal cortex and the precentral gyrus

Answer 30

The Frontal Lobe

Question 31

The Frontal Lobe Precentral gyrus

Answer 31

also known as the primary motor cortex; responsible for the control of fine motor movement

Question 32

The Frontal Lobe Prefrontal cortex

Answer 32

the integration center for all sensory information and other areas of the cortex (most anterior portion of the frontal lobe)

Responsible for:
Higher functions such as abstract thinking and planning

Our ability to remember recent events and information (“working memory”)
