INTRODUCTION Cross-modal plasticity has been extensively studied in deaf adults with neuroimaging studies, yielding valuable results. A recent study in our laboratory with deaf-blind children found evidence of cross-modal plasticity, revealed in over-representation of median nerve somatosensory evoked potentials (SEP N20) in left hemisphere parietal, temporal and occipital regions. This finding...

Abstract. The Ozone Mapping and Profiler Suite (OMPS) has been on board the Suomi National Polar-orbiting Partnership (S-NPP) satellite since October 2011 was followed by an OMPS NOAA-20 (N20) in November 2017 as part of US Joint Polar Satellite System (JPSS) program. measurements are processed to yield various products atmospheric composition data for near-real-time monitoring offline study, i...

The adsorption behaviour of N20 on the Si(001)2 × ! surface at 300 K substrate temperature has been investigated by measuring in situ the surface conductance during the reaction process. For comparison we monitored in the same way the adsorption of 0 2 on the same surface which ultimately leads to the fiat band situation. The adsorption of atomic oxygen as released by decomposition of the N20 m...

OXYGEN FAIL-SAFE SYSTEMS for anaesthetic gas machines have been advocated as standard safety features. 1-4 They are designed to prevent delivery of hypoxic gas mixtures in the event of an interruption or exhaustion of O~ pipeline or tank sources. In such a circumstance the fail-safe device causes all gas flow to cease, so alerting the operator of the apparatus to the problem. Some types of gas ...

In the analysis of MEG data one often faces the problem that noise from biological or technical origins (e.g. alpha activity or interference from the power line, respectively) is corrupting the measurements. We present a case study where we analyze the effects of artifact removal for a well-known experimental setting: measurements of somatosensory evoked fields (SEF, N20). We compare a classica...

Brain asymmetry is a phenomenon well known for handedness and language specialization and has also been studied in motor cortex. Less is known about hemispheric asymmetries in the somatosensory cortex. In the present study, we systematically investigated the representation of somatosensory function analyzing early subcortical and cortical somatosensory-evoked potentials (SEP) after electrical s...

INTRODUCTION Studies of neuroplasticity have shown that the brain's neural networks change in the absence of sensory input such as hearing or vision. However, little is known about what happens when both sensory modalities are lost (deaf-blindness). Hence, this study of cortical reorganization in visually-impaired child cochlear implant (CI) candidates. OBJECTIVE Assess cross-modal plasticity...

Long-term potentiation (LTP) and long-term depression (LTD) are regulated by homeostatic control mechanisms to maintain synaptic strength in a physiological range. Although homeostatic metaplasticity has been demonstrated in the human motor cortex, little is known to which extent it operates in other cortical areas and how it links to behavior. Here we tested homeostatic interactions between tw...
