Fig. 4From: Effect of pulsed transcranial ultrasound stimulation at different number of tone-burst on cortico-muscular couplingThe TE values between LFPs and EMG before and after stimulation. The “Line 1” showed the significant level between descending and ascending direction before ultrasound stimulation, the “Line 2” was after ultrasound stimulation. The Line 3 and Line 4 indicated the significant level between before and after stimulation of ascending direction (from EMG to LFPs) and descending direction (from LFPs to EMG), respectivelyBack to article page
