fMRI paradigm designed and post-processing tools

University of Minnesota - Twin Cities

- Neuroimaging studies have used changes in blood flow or chemistry to examine parts of the brain active while normal adults perform tasks.
- These studies have provided a general picture of where cognitive and emotional processing is carried out by the brain. They give hope of helping us understand how genetics and experience work together to produce the behavior patterns of the adult.
- Neuroimaging studies have examined in the brains of normal adults such processes as perception, working memory, language, spatial attention, attentional selection, arousal, and happy and sad emotional states.

Neuroimaging Studies

Functional magnetic resonance imaging (fMRI) is an effective tool for analyzing brain functionality. It is capable of tracking the functional response of the brain through Blood Oxygen Level Dependent (BOLD) contrast. Increased neuronal activity leads to local increase in energy and oxygen consumption. Essentially, the BOLD effect is a contrast caused by the relative decrease in the magnetic field irregularities due to relative increase in the oxyHb level contributed by the blood flowing in the brain region with increased activity.
