WebThe pathophysiology of focal somatosensory seizures depends upon the etiology of the primary brain process and the localization of the epileptic focus. Focal seizure originates from the epileptic focus, which is an area with reduced seizure threshold and hyperexcitability. A detailed discussion of the pathophysiology of an epileptic focus is ... WebApr 9, 2024 · The primary somatosensory cortex (S1) is a hub for body sensation of both innocuous and noxious signals, yet its role in somatosensation versus pain is debated. Despite known contributions of S1 to sensory gain modulation, its causal involvement in subjective sensory experiences remains elusive. Here, in mouse S1, we reveal the …

Directly suppressing L5 reproduced the pronociceptive phenotype induced by L6 activation, suggesting an anti-nociceptive function for L5 output. WebMay 18, 2024 · In the cerebral cortex, sensory processing begins at the primary sensory cortex, then proceeds to an association area, and finally, into a multimodal integration area.
