Brain Structures and Functions Lab

Hypothalamus

Part of the limbic system and regulates hunger, thirst, and body temperature Helps govern the endocrine system through the pituitary gland

Auditory Cortex

Processes information from the ears, primarily from the opposite side of the body

Visual Cortex

Processes information from the eyes coming from the opposite visual field

Sensory Cortex

Processes sensations from the skin and internal organs on the opposite side of the body

Wernicke's Area

Processes the information from speech or writing and comprehends its meaning

Temporal Lobe

Receives and processes auditory information from the ears Located on the side of the brain Contains the auditory cortex

Parietal Lobe

Receives and processes sensory information from the skin and body senses Located between the frontal and occipital lobes Contains the somatosensory cortex

Occipital Lobe

Receives and processes visual information from the eyes Located in the back/base of the brain Contains the visual cortex

Pons

Relays messages between the cerebellum and the cortex to help coordinate movement

Thalamus

Relays sensory messages to the cortex Replies to the cerebellum and medulla

Angular Gyrus

(Involved with reading) Turns written words into an auditory code to be interpreted by Wernicke's area

The video indicates that obsessions have their basis in

Altered brain structure

Medulla

Controls breathing, heartbeat, and other vital functions

Frontal Lobe

Controls muscle movement and production of speech Is involved in making plans and judgements Contains the motor cortex

Motor Cortex

Controls voluntary muscle movements on the opposite side of the body

Cerebellum

Coordinates movement and balance Processes some sensory input

The medication used to treat Theodore is normally used to treat

Drug addiction

Reticular Formation

Filters incoming stimuli Helps regulate arousal and alertness

In an attempt to replace the thrill he once associated with gambling, Theodore

Flies a helicopter

Broca's Area

Generates spoken and written language Controls mouth muscles by the way of the motor cortex

Why did you present information to both the left and right field of vision?

Information presented to one visual field would test processing only in the opposite brain hemisphere (left field of vision→ right brain hemisphere, right field of vision→ left brain hemisphere)

Hippocampus

Involved in learning and forming new memories

Amygdala

Involved in the regulation of the emotions of fear and rage

The electrical stimulation of the brain is conducted while the patient:

Is awake

In your study, whether participants spoke English fluently was a confounding variable because

It could affect their ability to identify the word you showed them

Michael's response to his injury is marked by

Little awareness of how it has transformed him

Our reflexes are governed by the

Spinal cord

Which part of the cerebral cortex deals with abstract thinking, planning, executive control, and judgment—the qualities that make us most human?

The frontal lobe

Cerebral Cortex

The outer surface of the upper part of the brain. Its 4 lobes contain the body's ultimate control centers and information-processing areas

Which structure is the conductor, or "master gland," of the hormone-producing system?

The pituitary gland

Why was it a good idea to measure responses of a group of people rather than a single person or small group of people?

This would allow you to apply your results to the general population

Electrical stimulation of the brain indicates that

Various brain regions have particular functions

Michael's explanation for why he continued gambling, even though he was suffering losses, was that he

Was playing with the experimenter's money rather than his own

Why was it important to use an experimental design?

You need to be able to study a large group of people and their brain's response to images presented to their left and right brain hemispheres
