Time-dependence evaluation of the primary visual cortex by 1H MR-spectroscopy using a stimulation control system.

Unlabelled: Proton magnetic resonance spectroscopy ((1)H MRS) is used to evaluate tumors and their remaining function under the assumption that event-related inspection and a method of data collection dependent on time are difficult. Therefore, this study examined the possibility that time depended on in MRS with a visual cortex. We conducted experiments using the following stimulations: REST: eyes are in a closed state,

Control: eyes are in an open state, and Continuous: consecutive stimulation and time dependence in the visual cortex.
