PSY 3061 Lecture Notes - Lecture 9: Diffusion Mri, Voxel, Radioactive Tracer
Document Summary
[computed (axial) tomography (ct): a device for imaging the brain 2d, like a photo. Magnet = coil with an electrical current: transceiver/receivers are also coils that stimulate or measure the magnetization of what is in the scanner. [what can you do with extra strong magnets?: a major goal of the human connectome project is to map the white matter connections within and between brain regions, using techniques such as dti, diffusion tensor imaging (dti) [imaging brain function: positron emission tomography (pet, radioactive tracer molecules, functional mri (fmri, oxygenated blood flow, multi-modal imaging, integration of 2 or more brain measures (combined eeg & mri). [positron-emission tomography (pet): pet uses radioactive tracers to study the activity of molecules in the brain. 2-deoxyglucose (2-dg) is glucose with a radioactive tracer attached to it: in the brain, glucose is used for energy, radioactive tracers can be attached to other molecules with neurobiological activity as well (ex.
