In another study, expert (pain-free) meditators showed lower activity in the mid-cingulate cortex, secondary somatosensory cortex, and insula during the painful stimulus [30].
Our present study demonstrated a significantly decreased FA in the sensorimotor WM that could be partially responsible for the anatomical changes in Somatosensory Cortex Area (S1) and Primary Motor Cortex Area (M1) [18, 3039].
assessed the functional and structural neuroplasticity in the somatosensory cortex when the fingers were electrically or mechanically stimulated [1, 3].
Several studies have shown that rSS applied to the index finger improves tactile spatial 2-point discrimination (2ptD) of that finger, presumably via functional reorganization within the somatosensory cortex [5, 26].
As shown in Table 2 and Figure 2, when performing finger movements compared with the healthy control group, it showed increased activation in the contralateral PCC (posterior cingulate cortex), MI (primary motor cortex), SI (primary somatosensory cortex), middle temporal gyrus and ipsilateral CMA (cingulate motor area), precuneus, and transverse temporal gyrus.
The primary somatosensory cortex (S1) and the primary motor cortex (M1) are well known for their precise physical representation of the body on the cortex, thereby providing a perfect location to explore the reorganization of the brain caused by BP.
The brains somatosensory cortex, in charge of processing sensory vibration stimulation, is hypoactive in patients and therefore the activity is reduced.
Information about texture is transmitted from sensors in the skin and through the nerves to the somatosensory cortex, the part of the brain responsible for interpreting the sense of touch.
The biggest peaks were in the somatosensory cortex, a strip of neural tissue that runs across the top of the brain like a headphone band.
