2
Biology and Behavior Neuroscience Scientific study of the brain and of the links between brain activity and behavior
3
Studying the Brain: Research Methods EEG (electroencephalograph) – - Device for recording brain waves, typically by electrodes placed on the scalp - Measures electrical activity in the brain
4
Studying the Brain: Research Methods Damage studies/Lesioning Tissue damage that results from disease or injury Epilepsy – Brain disorder that is often marked by seizures and loss of consciousness; caused by out-of-control electrical activity in the brain
5
Studying the Brain: Research Methods Electrical stimulation (ESB) Most research is done with animals Sometimes used in humans to “map” brains before surgery
6
Studying the Brain: Research Methods Transcranial magnetic stimulation (TMS) Magnetic paddle causes “virtual” lesions, temporarily disabling part of the brain
7
Brain imaging – recordings of the brain’s electrical or biochemical activity at specific sites Computerized Tomography (CT): computer enhanced X-ray of brain structure Studying the Brain: Research Methods
8
Positron Emission Tomography (PET) Records radioactivity emitted by cells during cognitive and behavioral activities Shows function of the brain
9
Studying the Brain: Research Methods Magnetic Resonance Imaging (MRI) Scans the brain using magnetic fields and radio waves Functional Magnetic Resonance Imaging (fMRI) Detects magnetic changes in blood flow to cells and oxygen level in the brain to show areas of high activity
