- 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
