Specific areas of the brain support specific cognitive functions.

Removal of a portion of the brain, typically in animal studies.

Focused damage to a specific area of the brain, often caused by electrodes.

Study of the relationship between the brain and behavior in humans.

Tests that assess verbal and non-verbal functions affected by brain damage.

Determines the extent of functional loss due to brain damage during tests.

The ability to hold and manipulate information in memory for short periods.

A neuropsych test measuring how many digits a person can recall in order.

Brain areas active when at rest or mind wandering.

Functional MRI measures brain activity by detecting changes in blood flow.

Basic units of the brain that transmit information.

Outer layer of the brain containing ~80% of its neurons.

Defining brain areas based on their functions.

Brain region responsible for somatosensory processes and visual processing.

Involves complex cognitive tasks, decision making, and emotional regulation.

The two hemispheres of the brain have different specialized functions.

Brain region responsible for visual processes like color and spatial awareness.

Lobe that processes auditory information and high-level visual tasks.

Region in the frontal lobe essential for speech production.

Brain area involved in executive functions, planning, and self-awareness.

Region that processes sensory information from the body.

Area responsible for processing auditory information.

Brain regions that integrate multiple sensory inputs and higher cognitive processes.

Damage here leads to issues with impulse control, empathy, and planning.

The use of mild electric current to activate brain areas, potentially enhancing or disrupting cognitive functions.

A neurosurgeon known for stimulating awake patients' brains during surgery to observe effects and sensations.

Direct stimulation of the brain while the patient is awake, with noted sensations and movements.

Techniques to stimulate brain areas without surgery, resulting in less focused stimulation.

A imaging technique that takes 3D slices of the brain to reveal tumors and lesions, similar to powerful x-rays.

Instantaneous results and non-invasive nature make it a useful imaging technique.

Includes exposure to radiation and poor spatial resolution in images.

A non-invasive imaging technique that uses a magnet to create detailed images of brain structures.

Offers great spatial resolution and is mostly low risk and non-invasive.

Can have contraindications and is often less accessible for patients.

A method that records electrical activity of groups of neurons through electrodes.

Provides excellent temporal resolution and is low risk and non-invasive.

Has poor spatial resolution and can be sensitive to movement.

Measures brain activity by detecting changes in blood oxygen levels during tasks.

Groups of brain areas that communicate to support cognitive functions.

Located in the frontal lobe, responsible for speech production.

Located in the temporal lobe, responsible for speech comprehension.

Bundle of fibers connecting the left and right hemispheres of the brain.

Specializes in language and mathematical skills.

Specializes in facial recognition and spatial tasks.

Certain tasks utilize one hemisphere more than the other.

Neurons represent and process information in the brain.

Each hemisphere of the brain controls the opposite side of the body.

Both hemispheres process vision, but each first processes its opposite visual field.

A surgical procedure that cuts the corpus callosum to prevent seizure spread.

Individuals with a commissurotomy, leading to rapid communication loss between hemispheres.

In split brain patients, the lack of communication means each hemisphere functions independently.

Information from the right visual field is processed by the left hemisphere first.

Information from the left visual field is processed by the right hemisphere first.

Split brain patients can name objects seen in the right field, but not from the left field.

A researcher known for his work on split brain patients and their hemispheric functions.
