“…Single dipoles in these areas accounted for large proportions of the variance in the scalp voltage distribution. Previous studies that have used mechanical displacement of the fingers or wrist to elicit SEPs have reported topographic maps similar to those observed here with a frontal negative and a parietal positive voltage distribution and with similar dipole orientations (Bötzel et al 1997;MacKinnon et al 2000;Seiss et al 2002). However, in the MacKinnon and Seiss papers, the estimated current source was more anterior than here, in primary motor cortex.…”

Nasir SM, Darainy M, Ostry DJ. Sensorimotor adaptation changes the neural coding of somatosensory stimuli. J Neurophysiol 109: 2077-2085, 2013. First published January 23, 2013 doi:10.1152/jn.00719.2012.-Motor learning is reflected in changes to the brain's functional organization as a result of experience. We show here that these changes are not limited to motor areas of the brain and indeed that motor learning also changes sensory systems. We test for plasticity in sensory systems using somatosensory evoked potentials (SEPs). A robotic device is used to elicit somatosensory inputs by displacing the arm in the direction of applied force during learning. We observe that following learning there are short latency changes to the response in somatosensory areas of the brain that are reliably correlated with the magnitude of motor learning: subjects who learn more show greater changes in SEP magnitude. The effects we observe are tied to motor learning. When the limb is displaced passively, such that subjects experience similar movements but without experiencing learning, no changes in the evoked response are observed. Sensorimotor adaptation thus alters the neural coding of somatosensory stimuli. motor learning; somatosensory evoked potential; reaching movement IS THE NEUROPLASTICITY THAT is associated with motor learning limited to motor areas of the brain, or do the effects of learning extend into nonmotor areas and notably into sensory systems? It is known that there are substantial anatomical interconnections linking the brain's motor and somatosensory regions. Cortical motor areas receive direct inputs from primary (Darian-Smith et al. 1993;Jones et al. 1978) and second somatosensory cortex (Cipolloni and Pandya 1999;Krubitzer and Kaas 1990) and from parietal areas 5 and 7 (Ghosh and Gattera 1995;Petrides and Pandya 1984). Somatosensory areas get direct cortical inputs from primary motor cortex (Darian-Smith et al. 1993;Jones et al. 1978;Krubitzer and Kaas 1990), premotor cortex (Cipolloni and Pandya 1999), and from supplementary motor area (Cipolloni and Pandya 1999;Jones et al. 1978). A change in somatosensory function in association with motor learning would seem to be a natural by-product of this anatomical connectivity. However, apart from behavioral studies (Cressman and Henriques 2009;Haith et al. 2008;Ostry et al. 2010;Wong et al. 2011) and a recent analysis of changes to resting-state networks in association with motor learning (Vahdat et al. 2011), there is little direct evidence that motor learning produces changes in sensory systems. Here we show that motor learning indeed alters the response of somatosensory areas of the brain. The changes we observe are substantially linked to motor learning in the sense that they vary in magnitude with motor learning, and they are not obtained when subjects passively experience the same movement kinematics, but do not experience learning.We studied motor learning using a force-field adaptation paradigm (Shadmehr and Mussa-Ivaldi 1994) in which subjects had to re...

“…Note that the averaging includes both the flexion and the extension movements. This procedure enhances the signal to noise ration in the estimated StrEPs and has previously been applied (Seiss et al, 2002). We confirmed the similarity between StrEP waveforms elicited by flexion and extension movement in preliminary anal-ysis (see figure 6.2).…”

“…The response to 55 electrical stimulation of the median nerve at the wrist is widely used in clinical practice. Also, the response evoked by muscle stretch has been studied (Abbruzzese et al, 1985;MacKinnon et al, 2000;Seiss et al, 2002). MacKinnon et al (2000) and Seiss et al (2002) compared the location of sources generating the evoked potentials elicited electrically and by muscle stretch.…”

“…This elicits a cortical response which can resemble sensory feedback and subsequent sensorimotor integration in movement control more closely, with a large contribution of muscle spindle afferent feedback (Starr et al, 1981;Abbruzzese et al, 1985;MacKinnon et al, 2000;Seiss et al, 2002;Mima et al, 1996). It was shown that such a muscle stretch evoked potential (StrEP) has a different shape and involves activation of other cortical areas compared to the electrical SSEP (MacKinnon et al, 2000;Seiss et al, 2002). More specifically, the sources generating the first peaks of the StrEP are positioned a few centimetres anterior of the sources of the first peak (N20) of the electrical SSEP.…”

“…More specifically, the sources generating the first peaks of the StrEP are positioned a few centimetres anterior of the sources of the first peak (N20) of the electrical SSEP. Authors concluded that the StrEP is generated, at least in part, by the primary motor cortex (MacKinnon et al, 2000;Seiss et al, 2002), while the electrical SSEP is generated by the primary sensory cortex (Allison et al, 1991).…”

IntroductionPrevious studies have reported the slowing of reaction times to attentionally demanding tasks due to a reduction in cognitive resource as a result of chronic high‐altitude exposure. However, it is still largely unknown whether this reaction slowness can be attributed to the attentional allocation change and/or response patterns.MethodsTo clarify this issue, this study investigated attention‐related (N2pc and N2 cc) and response‐related (MP and RAP) event‐related potentials (ERPs) to identify the performance of a visual search task by individuals who had lived in high‐altitude areas for three years compared with those living at sea level.ResultsThis study showed that the reaction times in response to a visual search task were significantly longer in the high‐altitude subjects than in the sea level subjects. Corresponding to this behavioral observation, we found a significantly lower N2pc amplitude and a larger N2 cc amplitude in the high‐altitude subjects, suggesting a reduction in spatial attention allocation to the target (N2pc) in these subjects, indicating they need to work harder to preclude cross‐talk between response selection and attention direction (N2 cc). Moreover, we also discovered higher MP amplitudes and longer RAP latencies in the high‐altitude subjects, which further indicated that these subjects were slower and required greater cortical activation while preparing and executing correctly selected responses (MP and RAP).ConclusionNevertheless, this study collectively provided new insights into the attention reaction slowness from high‐altitude exposure.
