neuroimaging
Neuroimaging refers to a variety of techniques used to make pictures of the Central Nervous System. There are two general types of neuroimaging: functional neuroimaging and structural neuroimaging.

Functional Neuroimaging:

Functional neuroimaging is used to find out what areas of the brain are active at a particular time. It is usually combined with a particular task. For example, a neuroscientist studying language development in children might use a functional neuroimaging technique to find out which neurons respond to a particular language sound.

Functional neuroimaging techniques:

  • Positron Emission Tomography (PET,PET Scan)
  • functional Magnetic Resonance Imaging (fMRI)
  • Single-Photon Emission Computed Tomography (SPECT)
  • Magnetic Resonance Spectroscopy (MRS)
  • Magnetoencephalography (MEG)
  • Electroencephalography (EEG)

Structural Neuroimaging:

Structural neuroimaging is used to look at the structure of the brain. It is often used to locate tumors and areas involved in brain damage.

Structural neuroimaging techniques:

  • Magnetic Resonance Imaging (MRI)
  • Computed (Axial) Tomography (CT Scan)
  • Diffusion Tensor Imaging (DTI)

Sometimes functional and structural neuroimages will be overlapped to assist in their interpretation.
