Provided insights into the role of the frontal lobe in personality and behavior.

Advanced our understanding of hemispheric specialization through split-brain studies.

Because it's the control center for everything we do, think, and feel.

Language, logic, linear thinking, math, and analytical thinking; controls the right side of the body.

Visual-spatial processing, music, art, emotional processing; controls the left side of the body.

Detailed images of the brain's structure, useful for identifying tumors or injuries.

Measures blood flow changes to show which brain areas are active during specific tasks, combining structure and function.

Particularly useful when studying rare or unusual phenomena.

To understand the function of a specific brain area by observing the resulting behavioral changes after its destruction.

To activate specific brain areas to observe the responses, helping to understand their function.

CT uses X-rays for structural images; MRI uses magnetic fields for more detailed soft tissue images.

PET uses radioactive glucose to track activity; fMRI measures blood flow for more precise functional imaging.

EEG measures electrical activity with electrodes, good for sleep studies; fMRI measures blood flow for detailed functional images.

Lesioning destroys brain tissue to observe effects; brain stimulation activates regions to observe responses.

Case studies are in-depth analyses of individuals; experimental studies involve manipulating variables to find cause-and-effect relationships.

CT scans provide two-dimensional images of the brain using X-rays, while MRI scans provide more detailed images of the brain's soft tissues using magnetic fields and radio waves.

fMRI scans have higher spatial resolution than PET scans, allowing for more precise localization of brain activity.

PET scans are more invasive than fMRI scans because they involve exposure to radiation.

EEG scans have higher temporal resolution than fMRI scans, allowing for the detection of rapid changes in brain activity.

CT scans are typically used to quickly rule out bleeding in the brain after a stroke, while MRI scans can provide more detailed information about the extent of brain damage.

An in-depth investigation of a single individual or small group, often used for rare phenomena.

The intentional destruction of specific brain tissue to observe behavioral changes.

Using electrical or chemical means to activate specific brain areas to observe responses.

Electroencephalogram; uses electrodes to measure electrical activity in the brain.

Positron Emission Tomography; uses radioactive glucose to track brain activity.

Computed Tomography; uses X-rays to create a detailed image of the brain's structure.

Magnetic Resonance Imaging; uses magnetic fields and radio waves to create detailed images of the brain's soft tissues.

Functional MRI; combines MRI's structural detail with PET's functional tracking, measuring blood flow changes.

The concept that each hemisphere of the brain has specialized functions.

Individuals whose corpus callosum has been severed, often to treat severe epilepsy.
