Measuring Brain Functionality
Positron Emission Tomography (PET)
Radioactive tracer (picked up by machine)
Increased blood flow --> More brain activity
Magnetic Resonance Imaging (MRI)
Subtraction technique
Change in O2 in blood --> changes magnetism of blood
Diffusion Tensor Imaging (DTI
Detects how water diffuses along nerve fibres
Neural Networks
Dissociation
