Tools We Use to Study the Brain

CAT Scan-
CAT Scans form a full 3-Dimensional model of a patient's insides. Doctors can examine the body one slice at a time to pinpoint specific areas.

Structural Magnetic Resonance Image-
Deals with the structure of the brain and the diagnoses of gross intracranial disease and injury. 

Diffusion Tensor MRI- 
A technology that measures the random motion of hydrogen atoms within water molecules in all 3 dimensions, non-invasively. 


EEG- 
Electroencephalography is the recording of electrical activity along the scalp. An EEG is mainly used to diagnose and manage epilipsy. 

PET Scan-
An imaging test that uses a radioactive substance called a tracer to look for disease in the body. It shows how the brain and it's tissues are working. 
fMRI-
functional neuroimaging procedure using MRI technology that measures brain activity by detecting associated changes in blood flow.

phMRI-
A molecular imaging technique using the natural hemodynamic transduction related to neuro-receptor stimulus.
TMS-
A noninvasive method to cause depolarization or hyperpolarization in the neurons of the brain
