The area of S1 activated during VS of the digits in a normal control subject was coextensive with the ventral S1 region abnormally activated during VS of the ectopic phantom representation in the two amputees, suggesting that the deafferented digit or hand/arm area had been activated by sensory input from the pectoral region. | |||||||||||||||
| |||||||||||||||
|
The contralateral S1 cortex was activated during painful mechanical stimulation of the hand, whereas tooth pain lead to bilateral activation of S1. | |||||||||||||||
| |||||||||||||||

The area of S1 activated during VS of the digits in a normal control subject was coextensive with the ventral S1 region abnormally activated during VS of the ectopic phantom representation in the two amputees, suggesting that the deafferented digit or hand/arm area had been activated by sensory input from the pectoral region. | |||||||||||||||
| |||||||||||||||
|
Results indicate that the S1 is not only involved in the actual perception of pain and touch but also plays an important role in extracting somatic features from social interactions. | |||||||||||||||
| |||||||||||||||
|
[A case of gastric cancer with multiple bone metastasis that responded to S-1 with low-dose cis-platinum]. | |||||||||||||||
| |||||||||||||||
|
Subgroup analysis using rating-weighted predictors revealed activation of the contralateral thalamus, anterior cingulate cortex, and amygdala and a bilateral activation of S1, S2, and insular cortex and prefrontal cortices in allodynia-experienced subjects. | |||||||||||||||
| |||||||||||||||
|
VS of the pectoral region adjacent to the intact arm was associated with activation of the dorsal part of the contralateral primary somatosensory cortex (S1) in a position consistent with the S1 trunk area. | |||||||||||||||
| |||||||||||||||
|
In contrast, VS of the pectoral region ipsilateral to the amputation with RS was associated with activation of the contralateral S1 that extended from the level of the trunk representation ventrally over distances of 20 and 12 mm, respectively, in the two subjects. | |||||||||||||||
| |||||||||||||||
|
The contralateral S1 cortex was activated during painful mechanical stimulation of the hand, whereas tooth pain lead to bilateral activation of S1. | |||||||||||||||
| |||||||||||||||
|
The results of direct stimulation of the S1 nerve root and recording from the soleus are shown in Table 2. | |||||||||||||||
| |||||||||||||||
|
For both evoked and spontaneous tics, activation in S1 (PoCG, Brodmann Area 2 or 3) was observed contralateral to the pain in the area corresponding to the somatotopic representation of the origin of the painful tics (i.e., face actual pain was just lateral to the upper right lip). | |||||||||||||||
| |||||||||||||||
|
[A case of ascending colon cancer with enlarged metastatic lymph nodes around superior mesenteric arterial root that responded dramatically to S-1 and CPT-11 combination chemotherapy]. | |||||||||||||||
| |||||||||||||||
|
It potentially could be attributed to activation in S1 and S2 and recorded together, since both are activated by noxious stimuli [13]. | |||||||||||||||
| |||||||||||||||
|
In prior studies using fMRI we have reported specific and somatotopic activation in the S1 region following similar painful thermal stimuli to the three divisions of the face [12], [13] that included the one used here, i.e., the ophthalmic division of the trigeminal nerve also designated as V1 or the first division of the nerve. | |||||||||||||||
| |||||||||||||||
|
In contrast, allodynia-inexperienced subjects only activated contralateral S1 and bilateral S2. | |||||||||||||||
| |||||||||||||||
|
The group analysis of all subjects revealed that tactile stimulation activated contralateral somatosensory cortices (S1 [primary] and S2 [secondary]), but the imagination of allodynia led to an additional activation of anterior cingulate cortex and bilateral activation of S2, insular cortex, and prefrontal cortices. | |||||||||||||||
| |||||||||||||||
|
Studies of sensorimotor cortical activation following innocuous stimulation have reported both unilateral [7] as well as bilateral S1 activation [8], [9]. | |||||||||||||||
| |||||||||||||||
|
For simplicity, this activation is referred to in the manuscript as S1 activation. | |||||||||||||||

|
Maihöfner et al. [26] observed activations in the S1 and S2 cortex, insula, PFC, and in the ACC during pin-prick stimulation of CRPS patients who experience hyperalgesia. | |||||||||||||||
