Lobes
Refers to the portion of the brain behind the forehead, involved in speaking and muscle movements, making plans, judgements; decision making
What is the frontal lobe?
Series of X-ray photographs taken from different angles, combined by computer into a composite representation
What is a CT (CAT) scan?
Core of the brain, responsible for autonomic survival functions
What is the brainstem?
Ear shaped neural system located below the cerebral hemispheres associated with emotions and drives
What is the limbic system?
Controls language reception language comprehension and expression, left temporal lobe, disrupts understanding
What is the wernicke's area?
Refers to the portion of the brain lying at the top of the head and toward the rear; receives sensory input for touch, pressure, temperature, and body position
What is the parietal lobe?
Technique uses magnetic fields and radio waves to formulate computer generated images of soft tissue, shows brain anatomy
What is an MRI?
Base of brainstem, controls breathing, heartbeat, reflex center, involuntary functions (sneezing, vomiting)
What is the medulla?
Helps coordinate movements and handles unconscious processes and jobs, such as your sleep-wake cycle and breathing
What is the pons?
Controls language expression, muscle movements involved in speech, left frontal lobe disrupts speaking
What is the broca’s area?
Refers to the portion of the brain lying at the back of the head and responsible for receiving information from visual fields
What is the occipital lobe?
Recording of the waves of electrical activity (brain waves) that sweep across the brain’s surface
What is an EEG?
Important functions in motor movement, particularly movements of the eye, and in auditory and visual processing
What is the midbrain?
Linked to emotion and reward (dopamine release)
Surgery that isolates the brain hemispheres by cutting the corpus callosum
What is split brain?
Refers to the portion of the brain above the ears, including auditory areas, each receiving information primarily from the opposite side
What is the temporal lobe?
Visual display of brain activity that detects where a radioactive form of glucose does when the brain performs a task
What is a Positron Emission Tomography Scan (PET)?
Little brain” at the rear of the brainstem; functions include processing, sensory input and coordinating movement, output & balance
Large band of neural fibers connecting the two brain hemispheres
What is the corpus callosum?
Body's ultimate control and information processing center
What is the cerebral cortex?
Refers to the brain having two of each lobe
What are the two brain hemispheres?
Test that reveals blood flow and brain activity
What is Functional Magnetic Resonance Imaging (fMRI)?
Brain’s sensory switchboard; all senses except small pass through it
What is the thalamus?
Body's ultimate control and information processing center
What is the cerebral cortex?
Case study that focused on a patient with severe epilepsy, searching to reduce seizures through split brain surgery
