  • clinical study – examine how brain diseases affect personality , behavior or sensory capacities 
    • ablation – surgical removal of tisse )parts of brain)   
    • deep lesioning – thin wire electrode lowered into target area inside the brain – used to destroy a small amount of brain tissue 
    • micro electrode – extremely thin glass tuve filled with a salty fluid – tip of microelectrode small enough to detect electrical activity of a single neuron  
    • Electroencephalograph – measure waves of electrical activity produced by brain – disk shaped metal plates are placed on scalp to detect the small impulses  
    • computed tomographic scanning – specialized type of x ray – try to make the brain visible  
    • magnetic resonance imaging – uses strong magnetic field to produce an image of body’s interior  
    • electrical simulation – turn on brain structures – activate target areas
