We recorded the magnetoencephalographic (MEG) signal from three subjects before, during and after eye movements cued to a tone, self-paced, awake and during rapid eye movement (REM) sleep. During sleep we recorded the MEG signal throughout the night together with electroencephalographic (EEG) and electromyographic (EMG) channels to construct a hypnogram.(More)
In the cerebellar cortex, long-term depression (LTD) of synapses between parallel ÿbers (PF) and Purkinje neurons can spread to neighboring ones, independently of their activation by PF input. This spread of non-speciÿc LTD around the activated synapses resembles how units are aaected in the neighborhood of the winner in a Kohonen Network (KN). However in a(More)
