Section 1

(31 cards)

cerebral hemispheres

Front

right and left halves of the brain

Back

MRI (magnetic resonance imaging)

Front

a technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue.

Back

Magnetoencephalography (MEG)

Front

technique that measures brain activity by detecting tiny magnetic fields generated by the brain

Back

corpus callosum

Front

the large band of neural fibers connecting the two brain hemispheres and carrying messages between them

Back

Pons

Front

sleep and arousal

Back

Functional MRI (fMRI)

Front

shows brain activity at higher resolution than PET scan when changes in oxygen concentration in neurons alters its magnetic qualities

Back

cortex

Front

outermost covering of the brain consisting of densely packed neurons, responsible for higher thought processes and interpretation of sensory input

Back

Hypothalamus

Front

a neural structure lying below the thalamus; directs eating, drinking, body temperature; helps govern the endocrine system via the pituitary gland, and is linked to emotion

Back

Wernicke's area

Front

controls language development - a brain area involved in language comprehension and expression; usually in the left temporal lobe

Back

occipital lobe

Front

A region of the cerebral cortex that processes visual information

Back

Motor cortex

Front

an area at the rear of the frontal lobes that controls voluntary movements

Back

pareital lobe

Front

Lobe located at the top and back of the brain; contains the centers of touch; area processes from the skin and internal body receptors for touch, temperature, and body position.

Back

Frontal Lobe

Front

associated with reasoning, planning, parts of speech, movement, emotions, and problem solving

Back

Thalamus

Front

the brain's sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla

Back

left hemisphere

Front

controls the right side of the body; analytical, language, math (logic)

Back

Cerebellum

Front

A large structure of the hindbrain that controls fine motor skills.

Back

limbic system

Front

A doughnut-shaped system of neural structures at the border of the brainstem and cerebral hemispheres; associated with emotions such as fear and aggression and drives such as those for food and sex. Includes the hippocampus, amygdala, and hypothalamus. (memory and learning)

Back

Lesioning

Front

destroying a piece of the brain

Back

Temproal Lobe

Front

auditory sensation & perception

Back

Amygdala

Front

A limbic system structure involved in memory and emotion, particularly fear and aggression.

Back

Positron Emission Tomography (PET)

Front

a method of brain imaging that assesses metabolic activity by using a radioactive substance injected into the bloodstream

Back

reticular formation

Front

a nerve network that travels through the brain stem and thalamus and plays an important role in controlling arousal

Back

Hippocampus

Front

A neural center located in the limbic system that helps process long-term memories for storage.

Back

split brain

Front

a condition resulting from surgery that isolates the brain's two hemispheres by cutting the fibers (mainly those of the corpus callosum) connecting them

Back

right hemisphere

Front

controls the left side of the body; creative, intuitive, spacial (memory, reasoning, and problem solving)

Back

Medulla

Front

the base of the brainstem; controls heartbeat and breathing

Back

Electronencephalogram (EEG)

Front

an amplified recording of the waves of electrical activity sweeping across the brain's surface. These waves are measured by electrodes placed on the scalp.

Back

somatosensory cortex

Front

area at the front of the parietal lobes that registers and processes body touch, temperature, and movement sensations

Back

CT scan (computed tomography)

Front

a series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body

Back

Broca's area

Front

Controls speech production - an area of the frontal lobe, usually in the left hemisphere, that directs the muscle movements involved in speech.

Back

association areas

Front

areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking
