Modulation of corticospinal excitability during lengthening and shortening contractions in the first dorsal interosseus muscle of humans.

abstract：:In the present study pineal glands of rats aged 69-71 days were studied in vivo and in vitro with respect to day/night changes of "synaptic" ribbons and spherules. It was found that ribbons outnumber spherules by a factor of 3. In vivo, both ribbons and spherules show a roughly 3-fold increase in number at 1 a.m. when...
