Instruments of Neuroscience

Electroencephalograph (EEG)

• Records electrical impulses from electrodes placed on the scalp

Computerized Axial Tomography (CAT)

• 3 dimensional views of the inside of the human body (only anatomical information and no functional abilities)

Positron Emission Tomography (PET Scan) and Radioactive Tracers

• Provides information about the function of the brain

• Tracers are placed throughout the body through an injection

Magnetic Resonance Imaging (MRI)

• It is a medical imaging technique that uses strong magnetic fields and radio waves to generate detailed images of the body's internal structures. 

• It provides valuable information about the anatomy, function, and health of various organs and tissues without using ionizing radiation like X-rays.

Functional Magnetic Resonance Imaging (fMRI)

• Uses the MRI scan and fMRI specifically to look up at blood oxygenation and helps to map out the part of the brain involved in different functions
