fMRI of sensorimotor activation of the thalamus
2023
Max Planck Institute for Biological Cybernetics, Tuebingen, Germany
This study aims to identify the sensorimotor nuclei of the thalamus of humans using functional magnetic resonance imaging (fMRI) by assessing blood oxygen level-dependent (BOLD) response during an active motor and a passive sensory stimulation.
Ten healthy volunteers participated in the study. In the active motor task, participants were instructed to tap their right fingers in an ordered fashion against the thumb. In the passive sensory stimulation, pressure was delivered to different fingers of the participants. fMRI allowed to identify nuclei activated in the different tasks.
The study provides insight into the function of individual thalamic nuclei in processing various input signals and corroborates the benefits of fMRI to investigate deeply located brain structures.
