Monosynaptic connections between pairs of spiny stellate cells in layer 4 and pyramidal cells in layer 5A indicate that lemniscal and paralemniscal afferent pathways converge in the infragranular somatosensory cortex. [PDF]

, 2005
Monosynaptic interlaminar connections between spiny stellate cells in layer 4 (L4), the main cortical recipient layer for thalamic projections, and pyramidal cells in layer 5A (L5A), one of the main cortical output layers, were examined anatomically and ...

Linking pain and the body: neural correlates of visually induced analgesia [PDF]

, 2012
The visual context of seeing the body can reduce the experience of acute pain, producing a multisensory analgesia. Here we investigated the neural correlates of this “visually induced analgesia” using fMRI.

Normalization in human somatosensory cortex

Journal of Neurophysiology, 2015
Functional magnetic resonance imaging (fMRI) was used to measure activity in human somatosensory cortex and to test for cross-digit suppression. Subjects received stimulation (vibration of varying amplitudes) to the right thumb (target) with or without concurrent stimulation of the right middle finger (mask).

Effect of Prenatal Valproic Acid Exposure on Cortical Morphology in Female Mice

Journal of Pharmacological Sciences, 2012
We have recently shown that prenatal valproic acid (VPA) exposure causes autism spectrum disorders–like behavioral abnormalities and Nissl-positive cell loss in both prefrontal and somatosensory cortices in male mice.

NMDA receptors control development of somatosensory callosal axonal projections

eLife, 2021
Callosal projections from primary somatosensory cortex (S1) are key for processing somatosensory inputs and integrating sensory-motor information. How the callosal innervation pattern in S1 is formed during early postnatal development is not clear.

On the Geometry of Somatosensory Representations in the Cortex

NeuroImage
Abstract It is well-known that cortical areas specializing in the processing of somatosensory information from different parts of the body are arranged in an orderly manner along the cortex. It is also generally accepted that in the cortex, somatosensory information is initially processed in the primary somatosensory cortex and from ...

Rapid enhancement of touch from non-informative vision of the hand [PDF]

, 2012
Processing in one sensory modality may modulate processing in another. Here we investigate how simply viewing the hand can influence the sense of touch. Previous studies showed that non-informative vision of the hand enhances tactile acuity, relative to ...

Rich spatio-temporal stimulus dynamics unveil sensory specialization in cortical area S2

Nature Communications, 2018
Sensory tuning properties of neurons in the secondary whisker somatosensory cortex (wS2) are not well understood. Here, the authors report that wS2 neurons supralinearly integrate concurrent multi-whisker input with larger temporal windows than primary ...

MEG reveals a fast pathway from somatosensory cortex to occipital areas via posterior parietal cortex in a blind subject

Frontiers in Human Neuroscience, 2013
Cross-modal activity in visual cortex of blind subjects has been reported during performance of variety of non-visual tasks. A key unanswered question is through which pathways non-visual inputs are funneled to the visual cortex. Here we used tomographic

A supramodal representation of the body surface [PDF]

, 2011
The ability to accurately localize both tactile and painful sensations on the body is one of the most important functions of the somatosensory system.
