Signal-to-noise comparisons for X and Y cells in the retina and lateral geniculate nucleus of the cat.

abstract：:Since the moment arms for the elbow-flexor muscles are longest at intermediate positions of the elbow and shorter at the extremes of the range of motion, it was expected that the elbow torque would also show a peak at an intermediate angle provided the activity of the flexor muscles remained constant. We measured the ...
