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.

Studying sleep patterns, seizures, and overall brain activity.

To identify areas of high metabolic activity, such as tumors or areas affected by Alzheimer's disease.

In some cases, lesioning is used to treat severe epilepsy by destroying the brain tissue causing seizures.

To identify brain areas involved in specific cognitive processes like memory, language, and decision-making.

To understand and treat rare psychological disorders or unique patient cases.

Transcranial Magnetic Stimulation (TMS) can be used to treat depression by stimulating specific brain areas.

To quickly identify any structural damage like fractures, bleeding, or swelling in the brain.

To detect lesions or plaques in the brain and spinal cord, which are characteristic of MS.

By revealing how each hemisphere can function independently, providing insights into the neural basis of consciousness.

To monitor brain wave patterns during different stages of sleep, helping to diagnose sleep disorders.

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.
