Description

This protocol was used in a brain stimulation study where transcranial ultrasound stimulation was applied to the lateral geniculate nucleus and brain fMRI data was acquired during stimulation (online sessions) or before and after stimulation (offline sessions). The experimental design is described in more detail in the preprint "Ultrasound system for precise neuromodulation of human deep brain circuits" here: https://www.biorxiv.org/content/10.1101/2024.06.08.597305v1. Specifically, this protocol was used in the third planning session, the online sessions and the stimulation part of the offline sessions.
