The Somatosensory Evoked Potential [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1982
Three decades have elapsed since Dawson (1947) recorded the first somatosensory evoked potential (SEP). Simple superimposition of individual responses was possible because the patient had progressive myoclonic epilepsy. In this disease the SEP amplitude is much enhanced (Shibasaki et al, 1978; Kelly et al, 1981).

Preterm Perinatal Hypoxia-Ischemia Does not Affect Somatosensory Evoked Potentials in Adult Rats

Diagnostics, 2019
Somatosensory evoked potentials (SSEPs) are a valuable tool to assess functional integrity of the somatosensory pathways and for the prediction of sensorimotor outcome in perinatal injuries, such as perinatal hypoxia-ischemia (HI).

Randomized Multiresolution Scanning in Focal and Fast E/MEG Sensing of Brain Activity with a Variable Depth [PDF]

, 2020
We focus on electromagnetoencephalography imaging of the neural activity and, in particular, finding a robust estimate for the primary current distribution via the hierarchical Bayesian model (HBM). Our aim is to develop a reasonably fast maximum a posteriori (MAP) estimation technique which would be applicable for both superficial and deep areas ...

Modality-specific improvements in sensory processing among baseball players

Scientific Reports, 2021
Long-term skills training is known to induce neuroplastic alterations, but it is still debated whether these changes are always modality-specific or can be supramodal components. To address this issue, we compared finger-targeted somatosensory-evoked and

Neuronal functional connectivity among multiple areas of the rat somatosensory system during spontaneous and evoked activities [PDF]

PLoS Computational Biology 06/2013, 2012
Small-World Networks (SWNs) represent a fundamental model for the comprehension of many complex man-made and biological networks. In the central nervous system, SWN models have been shown to fit well both anatomical and functional maps at the macroscopic level.

Loss of oligodendrocyte ErbB receptor signaling leads to hypomyelination, reduced density of parvalbumin‐expressing interneurons, and inhibitory function in the auditory cortex

Glia, Volume 71, Issue 2, Page 187-204, February 2023., 2023
Main Point Loss of oligodendrocyte ErbB receptor signaling leads to A1 hypomyelination, reduced PV expression and density of PV+ neurons and synapses, hypoconnectivity of inhibitory circuits and shift of the E/I balance towards excitation. Abstract For a long time, myelin was thought to be restricted to excitatory neurons, and studies on dysmyelination

Alterations in microglial morphology concentrate in the habitual sleeping period of the mouse

Glia, Volume 71, Issue 2, Page 366-376, February 2023., 2023
Main Points We found regional differences of microglial morphology between the somatosensory cortex (SC), hippocampus (HC) and basal forebrain (BF). Cortical‐, but not HC‐ or BF microglial cell sizes negatively correlate with non‐REM sleep slow wave activity.

A subset of OPCs do not express Olig2 during development which can be increased in the adult by brain injuries and complex motor learning

Glia, Volume 71, Issue 2, Page 415-430, February 2023., 2023
Main Points A subset of OPCs do not express Olig2, of which population peaks in the juvenile brain while wanes with age. Plastic changes of the brain by acute injuries or complex motor learning stop the expression of Olig2 in OPCs. Abstract Oligodendrocyte precursor cells (OPCs) are uniformly distributed in the mammalian brain; however, their function ...

The effects of neck flexion on cerebral potentials evoked by visual, auditory and somatosensory stimuli and focal brain blood flow in related sensory cortices

Journal of Physiological Anthropology, 2012
Background A flexed neck posture leads to non-specific activation of the brain. Sensory evoked cerebral potentials and focal brain blood flow have been used to evaluate the activation of the sensory cortex.

Effects of desflurane and sevoflurane on somatosensory-evoked and motor-evoked potential monitoring during neurosurgery: a randomized controlled trial

BMC Anesthesiology, 2021
Background Better protection can be provided during neurosurgery due to the establishment of somatosensory-evoked potential (SEP) and motor-evoked potential (MEP) monitoring technologies.
