Chapter Five Methods

First 20 methods of chapter five

Cerebral Angiography

What method uses X-rays and an injected contrast dye to create images of blood vessels in the brain?

Computed Tomography (CT)

What method uses multiple X-ray images to create a detailed cross-sectional image of the brain?

Positron Emission Tomography (PET)

What brain-imaging method uses radioactive substances to measure brain activity?

Magnetic Resonance Imaging (MRI)

What method uses a strong magnetic field and radio waves to create detailed images of brain structure?

Functional Magnetic Resonance Imaging (fMRI)

What method measures changes in blood oxygen levels to show which areas of the brain are active?

Diffusion Tensor Imaging (DTI)

What method is used to map the movement of water molecules and examine white matter pathways in the brain?

Transcranial Magnetic Stimulation (TMS)

What noninvasive method uses magnetic pulses to temporarily stimulate or disrupt activity in a specific area of the brain?

Transcranial Direct Current Stimulation (tDCS)

What noninvasive method uses a weak electrical current applied through the scalp to change brain activity?

Electroencephalography (EEG)

What method records the brain’s electrical activity using electrodes placed on the scalp?

Magnetoencephalography (MEG)

What method records magnetic fields produced by the brain’s electrical activity?

Electromyography (EMG)

What method measures electrical activity produced by muscles?

Electrooculography (EOG)

What method records eye movements by measuring electrical changes around the eyes?

Skin Conductance

What method measures changes in the skin’s ability to conduct electricity due to sweating and emotional arousal?

Electrocardiogram (ECG)

What method records the electrical activity of the heart?

Blood Pressure

What measure records the force of blood pushing against artery walls?

Plethysmography

What method measures changes in blood volume in a specific part of the body?

Aspiration Lesions

What lesion method removes brain tissue by suction?

Radio-Frequency Lesions

What lesion method uses high-frequency electrical current to destroy brain tissue with heat?

Knife Cuts

What lesion method uses a small surgical blade to cut neural pathways?

Reversible Lesions

What lesion method temporarily stops activity in an area of the brain without permanently damaging it?
