Brain Imaging (fMRI & fNIR)

We are using fMRI (functional magentic resonance imaging) to analyze what brain areas are active (and to what degree) during context-dependent memory experiments.

We are using a wearable fNIR (functional near-infrared) system to research brain activations during various working memory tasks in different modalities. The fNIR system (named OTIS) is being developed by our collaborators at Archinoetics.

By knowing, in real-time, what brain areas are active during everyday tasks, can we improve human performance on these tasks by modifying how and when information will be displayed?
