Fig. 1From: Cathodal transcranial direct-current stimulation over right posterior parietal cortex enhances human temporal discrimination abilityA trace of T value in a representative task as an example. This figure shows the T value used for each trial in a representative task, performed by one participant in one tDCS condition. A plotting symbol represents whether the response was correct or not: plus correct response, minus incorrect response. A circle indicates a trial in which switching between decrease and increase was observed. In this example, 300Â msec was selected as the threshold because it was the minimum T value with the correct answer rate exceeding 75% (11 correct responses in 14 trials)Back to article page
