Discrimination of locomotion direction in impoverished displays of walkers by macaque monkeys.

abstract：:Detection of apparent motion in random dot patterns requires correlation across time and space. It has been difficult to study the temporal requirements for the correlation step because motion detection also depends on temporal filtering preceding correlation and on integration at the next levels. To specifically stud...
