Males are exposed to the effect of various environmental factors, which may decrease their reproductive capabilities. Phone electromagnetic power is very small, only a few hundredths of a microwave oven, but bec...

The relationship between vibration and human motor unit spikes elicited by reflex and voluntary actions was studied by means of cross-correlograms. Using this method motor unit spikes could be classified into two categories, locked spikes with good correlation to vibratory frequency and unlocked ones with poor correlation to vibratory frequency. 1. Inter-spike intervals of the locked spikes wer...

This study examines the rules governing the transfer of spikes between the retina and the lateral geniculate nucleus (LGN) with the goal of determining whether the most informative retinal spikes preferentially drive LGN responses and what role spike timing plays in the process. By recording from monosynaptically connected pairs of retinal ganglion cells and LGN neurons in vivo in the cat, we s...
