Abstract:
The thalamus is connected to different cortical regions of the brain and is therefore traditionally seen as the relay station for almost all sensory and motor signals. While previous fMRI studies investigated the involvement of cortical and subcortical brain areas in sensorimotor signal processing [1,2], the precise role of the thalamus in these mechanisms in humans is still under investigation. Since the thalamus consists of small nuclei located in the central part of the brain, imaging with sufficient spatial resolution is required. Driven by an increase in signal‐to‐noise‐ratio, fMRI at ultra‐high magnetic fields (≥ 7 Tesla) enables measurements of functional responses in individual thalamic nuclei.
