FMRI (functional magnetic resonance imaging)

    Cards (5)

    • changes in blood oxygenation and flow occur as a result of neural activity in specific parts of the brain
    • when a part of the brain is more active it consumes more oxygen and to meet this demands, increased blood flow is directed to the areas which is called the haemodynamic response
    • an fMRI produces 3D images highlighting the areas of the brain involved in particular mental processes
    • haemodynamic response- when blood rushes to the area to meet the demand for oxygen
    • activation maps- name of the 3D images created by fMRI
