• insular cortex
  • It could also reduce nociception, thermoception, and crude touch, but, since information from the spinothalamic tract is interpreted mainly by other areas of the brain (see insular cortex and cingulate gyrus), it is not as relevant as the other symptoms. (wikipedia.org)
  • Deeper in the lateral sulcus lies the ventral somatosensory (VS) area, whose outer edge adjoins areas PV and S2 and inner edge adjoins the insular cortex. (wikipedia.org)
  • Area S2 is interconnected with BA 1 and densely so with BA 3b, and projects to PV, BA 7b, insular cortex, amygdala and hippocampus. (wikipedia.org)
  • He demonstrated experimentally that the insular cortex is a critical platform for feelings, a finding that has been widely replicated, and he uncovered cortical and subcortical induction sites for human emotions, e.g. in ventromedial prefrontal cortex and amygdala. (wikipedia.org)
  • He also demonstrated that while the insular cortex plays a major role in feelings, it is not necessary for feelings to occur, suggesting that brain stem structures play a basic role in the feeling process. (wikipedia.org)
  • He has continued to investigate the neural basis of feelings and demonstrated that although the insular cortex is a major substrate for this process it is not exclusive, suggesting that brain stem nuclei are critical platforms as well. (wikipedia.org)
  • cortical areas
  • Maturation involves an increase in paired-pulse ratio (PPR) and steady-state amplitude in both cortical areas, and STP converges to similar values in adult barrel and visual cortex. (jneurosci.org)
  • stimulation
  • Importantly, our event-related fMRI protocol allowed separation of blood oxygen level-dependent (BOLD) signals elicited by somatosensory stimulation/discrimination from those attributable to subsequent critical reward-outcome signals given visually at trial end. (jneurosci.org)
  • visual evoked potentials, and somatosensory evoked potentials, which are elicited by electrical stimulation of peripheral nerve. (wikipedia.org)
  • whisker
  • Spatially and temporally precise mechanorreceptive whisker information reaches the S1BF cortex via the ventroposterior medial thalamic nucleus (VPM). (uam.es)
  • auditory
  • Like other sensory cortex (i.e., visual and auditory) the thalamic inputs project into layer IV, which in turn project into other layers. (wikipedia.org)
  • There, he did a cross-species analysis of the cochlear nucleus in large game cats and pinnipeds, did the first auditory cortical microelectrode maps in the macaque with John Brugge, and the first somatosensory maps in the macaque with neurosurgeon Ron Paul. (wikipedia.org)
  • Jeffress' model proposes that two signals even from an asynchronous arrival of sound in the cochlea of each ear will converge synchronously on a coincidence detector in the auditory cortex based on the magnitude of the ITD (Fig. 2). (wikipedia.org)
  • brainstem
  • Several brain regions including the bilateral anterior insula (AI), rostral anterior cingulate cortex (ACC), brainstem, and cerebellum were activated both in instances of first person painful experience and observed painful experience. (wikipedia.org)
  • sensations
  • In 1954, Penfield and Jasper evoked somatosensory sensations in human patients during neurosurgery by electrically stimulating the ceiling of the lateral sulcus, which lies adjacent to S1, and their findings were confirmed in 1979 by Woolsey et al. (wikipedia.org)
  • To its right, the somatosensory cortex is part of the famous homunculus, the strip of cortex that is responsible for making a map of body sensations through its interaction with touch receptors. (gregadunn.com)
  • brain
  • This cortex is set up so that the regions that respond to the body go from the bottom to the top of the brain. (reference.com)
  • The somatosensory and somatomotor cortexes are two adjoining narrow bands of the topmost central area of the brain, stretching roughly from ear to ear. (wisegeek.org)
  • In this study, we used whole-cell recording in acute brain slices to study synaptic development in mouse barrel and visual cortex. (jneurosci.org)
  • The somatosensory region of the brain was not shown by fMRI to be excited during pain observation, rather only when the pain was experienced firsthand. (wikipedia.org)
  • Research using brain-scanning technology found that stimulating nipples in women resulted in the activation of the genital area of the sensory cortex. (wikipedia.org)
