Although there are debates on direct MR imaging of neuronal activity, the feasibility of this topic has been finding in various different ways. Herein, we propose an effective method of line-scan-based FLASH (LS-FLASH) imaging to directly capture sensory responses of in vivo mouse brain with a 5-ms temporal resolution. The response delay of ~10 - 15 ms between the thalamus and somatosensory barrel cortex (S1BF) was observed when the electrical stimulation was applied to the left mouse whisker area.
