This wiki explores the methods that those interested in neuroscience most frequently employ when investigating and explaining cognitive processes in terms of brain structure and function.

Transcranial Magnetic Stimulation Overview, Advantages, Disadvantages

Optogenetics Overview, Advantages, Disadvantages

Electrophysiological recording of neurons Overview, Advantages, Disadvantages

Electroencephalography (EEG) Overview, Advantages, Disadvantages

Positron Emission Tomography Positron emission tomography (PET) is a three-dimensional brain imaging technique that takes advantage of changes in metabolism to localize brain activity. The most active parts of the brain use more metabolic processes than do relatively inactive parts of the brain and PET is able to track the metabolic flow. Oxygen-15, a radioactive tracer isotope is most commonly used High Spatial resolution No temporal resolution Invasive. Injection of radioactive molecules

Functional Magnetic Resonance Imaging Like PET, Functional magnetic resonance imaging (fMRI)
