Supporting Decisions With Transcranial Direct Current Stimulation in Healthy Young and Elderly Individuals

Supporting Decisions With Transcranial Direct Current Stimulation in Healthy Young and Elderly Individuals

Decisions are part of the daily life. On the neuronal level, activity in the dorsolateral prefrontal cortex (dlPFC) is important during complex decisions (e.g., whether something is emotional for a person or not). We apply transcranial direct current stimulation (tDCS) with the aim to increase dlPFC activity and thereby modulate decisions towards emotional content.
