BOLD-functional MRI is a useful tool to identify the brain function and to examine the functional effects on development, recovery, and reorganization. The most common stimulus-paradigm is the electrical forepaw/hindpaw stimulation to generate the evoked BOLD response. Although specific brain areas are involved in the somatosensory system, most studies in the anesthetized rodents have focused on the somatosensory cortex as it is difficult to detect activation in the subcortical areas. BOLD sensitivity is dependent on the field strength and affected by physiological condition under the anesthesia. Here, we demonstrated the thalamo-cortical BOLD response in mice under the ketamine-xylazine at 15.2T.
