The Brain and Reflex Behavior

Cerebrum or cerebral cortex:

________ handles the higher functions of thought and action.

Brain goes through extensive growth from

________ conception to birth and after birth, through infancy and later.

Cerebellum

________: receives information from the sensory systems, spinal cord, and other parts of the brain to coordinate balance and voluntary movement.

Parietal lobes

________: important in spatial location, maintaining attention, and motor control.

Brain imaging technology

________ is used to learn about the brains development.

Temporal lobes

________: have an active role in hearing, language processing, and memory.

Frontal lobes

________: involved in voluntary movement, thinking, personality, emotion, memory, sustained attention, and intentionality or purpose.

Brain stem

________:controls basic survival functions such as breathing, heart rate, and sleep.

Left hemisphere

right-side motor function; language centers (for right-handed people)

Right hemisphere

left-side motor function; humor and emotional tone

Occipital lobes

function in vision

Corpus callosum

connects the hemispheres

Some functions are lateralized, but

most need both sides

The cerebral cortex is

divided into two hemispheres: the left hemisphere and the right hemisphere

Brain areas do not

mature uniformly.

Brain goes from 25 percent of its adult weight at birth to

75 percent by the second birthday.

Brain grows from

“bottom-up”

Examples of brain imaging technology

* MEG, EEG, fMRI, fNIRS.

Where is the cerebellum located?

the top of the brain

The cerebrum/cerebral cortex accounts for how much of the brain’s mass?

2/3

What is the most primitive part of the brain?

The brain stem
