A technique which attempts to comprehend the complex structure of brain and its activities in detail; aids in understanding the connection between different parts of the brain and their consequent behaviour.
Types of brain mapping techniques:
Electrical impulses of the brain are measured.
Positron Emission Tomography (PET):
Intake of nuclear medicine or radioactive drug by the patient in order to image the body organs and tissues and show their corresponding activities.
Functional MRI (fMRI):
Used when there is a change in the flow of blood to a specific area of the brain. The neural activity of that area changes and requires more oxygen and hence the blood flow increases to an active part of the brain.
Pharmacological functional MRI (phMRI):
Studying the changes in neural activities of the brain to understand the effects of substances in a non-invasive way; especially helpful in understanding the mechanism behind disorders like depression and ADHD (Attention Deficit Hyperactivity Disorder).
Transcranial Magnetic Stimulation (TMS):
Used to cure depression in a non-invasive way when all other methods and treatments have failed; involves electromagnetic stimulation of the brain in order to control the mood of a person.
