Synopsis

Keywords: Neurotransmission, Spectroscopy

Motivation: Many types of visual stimuli were reported effective for visual perception. However, it’s uncertain whether certain types of visual stimuli illicit larger responses.

Goal(s): We aim to measure the metabolic changes in response to different types of visual stimuli to observe which types of visual stimuli can excite larger and more consistent responses.

Approach: We designed three different types of stimuli sessions ( non-sense images, houses, and faces) for visual stimulation and observed the metabolic changes in the fMRS data at 5T.

Results: Preliminary experiments show that compared to non-sense images and “no interesting” houses, faces stimulate larger responses with dynamic increase.

Impact: An fMRS study is implemented to measure the dynamic changes in response to different types of visual stimuli. Preliminary experiments indicate that faces stimulate larger responses.
