Deficits in Behavioral Functions of Intact Barrel Cortex Following Lesions of Homotopic Contralateral Cortex

Frontiers in Systems Neuroscience, 2018
Focal unilateral injuries to the somatosensory whisker barrel cortex have been shown cause long-lasting deficits in the activity and experience-dependent plasticity of neurons in the intact contralateral barrel cortex.

Myelin remodeling through experience-dependent oligodendrogenesis in the adult somatosensory cortex

Nature Neuroscience, 2018
Oligodendrocyte generation in the adult CNS provides a means to adapt the properties of circuits to changes in life experience. However, little is known about the dynamics of oligodendrocytes and the extent of myelin remodeling in the mature brain. Using

High-order thalamic inputs to primary somatosensory cortex are stronger and longer lasting than cortical inputs

eLife, 2019
Layer (L) 2/3 pyramidal neurons in the primary somatosensory cortex (S1) are sparsely active, spontaneously and during sensory stimulation. Long-range inputs from higher areas may gate L2/3 activity.

Tickle contagion in the rat somatosensory cortex

iScience, 2022
Summary: The cellular mechanisms of emotional contagion are unknown. We investigated tickle contagion and the underlying neuronal representations in playful rats.

Stimulus awareness is associated with secondary somatosensory cortex activation in an inattentional numbness paradigm

Scientific Reports, 2023
While inattentional blindness and deafness studies have revealed neural correlates of consciousness (NCC) without the confound of task relevance in the visual and auditory modality, comparable studies for the somatosensory modality are lacking.

c-Fos expression during temporal order judgment in mice. [PDF]

PLoS ONE, 2010
The neuronal mechanisms for ordering sensory signals in time still need to be clarified despite a long history of research. To address this issue, we recently developed a behavioral task of temporal order judgment in mice.

Structural and Functional Abnormalities of the Primary Somatosensory Cortex in Diabetic Peripheral Neuropathy: A Multimodal MRI Study

Diabetes, 2019
Diabetic distal symmetrical peripheral polyneuropathy (DSP) results in decreased somatosensory cortical gray matter volume, indicating that the disease process may produce morphological changes in the brains of those affected.

Layer-specific activation of sensory input and predictive feedback in the human primary somatosensory cortex

Science Advances, 2019
Using laminar fMRI, we show that prediction and sensory inputs activate specific layers in human primary somatosensory cortex. When humans perceive a sensation, their brains integrate inputs from sensory receptors and process them based on their ...

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 ...

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.
