Walking enhances peripheral visual processing in humans
Fig 2
Influence of surround contrast depends on movement state.
(A) SSVEP responses (left: referenced SSVEP power; middle: raw SSVEP power) and detection rates (right) significantly decreased with higher surround contrast levels during walking but not during standing still. Vertical lines indicate ±1 standard error, n = 25 (SSVEP); n = 30 (detection rate). Refer to S1 Table for break-down statistics. (B,C) Individual data from contrast level 0% and 100% for referenced SSVEP power and raw SSVEP power. Red lines indicate participants whose data patterns do not conform to suppression (detection rate at 100% contrast larger or equal to 0% contrast). (D) Same as B but showing the individual detection rate. The original data are available from https://doi.org/10.6084/m9.figshare.9094742.v1. SSVEP, steady-state visual evoked potential.
