Abstract(in English) | Recently, many sleep researchers are interested in the relationship between sleep and synaptic plasticity. In this study, we trained rats in skilled reaching, and measured sleep EEG in the motor cortex after the training. We found that i) slow wave EEG, whose frequency is 0.5-4.5Hz, was increased for 4h after the training in both sides of the motor cortex, ii) the progressive increment of the delta power of the trained side relative to the untrained side was found, but this asymmetry was no longer present after 4h of sleep. These results suggest that the training of skilled reaching, which presumably induces synaptic potentiation, results in slow wave EEG increases during subsequent sleep, and sleep returns the synaptic weight to a baseline level. |
