Pain somatosensory cortex

WebBody representations are reliant on multi-sensory cortical and sub‐cortical areas, including particularly premotor cortex, posterior parietal cortex and the putamen. It is also important to note that the experience of sensing often involves a more complex integration of somatosensory inputs, and may be influenced by emotional and social contexts as well [2] .

WebHere we used somatosensory-evoked potentials (SEPs) to investigate whether mere observation of painful and tactile stimuli delivered to a model would modulate neural activity in the somatic system of an onlooker. Viewing video clips showing pain and tactile stimuli delivered to others, respectively, increased and decreased the amplitude of the ... WebNociceptive inputs are conveyed via the spinothalamic pathways to the brain, engaging multiple regions such as the primary and secondary somatosensory cortices, the prefrontal cortex, the insula, and the anterior cingulate cortex, as well as subcortical areas like the thalamus (Apkarian et al., 2005). primer phallebeauty https://itsbobago.com
