Reorganization of reflex responses mediated by different afferent sensory fibers after spinal cord transection.

abstract：:A new method is presented based on trinary logic able to check the state of different control variables and synchronously record the physiological and behavioral data of behaving animals and humans. The basic information structure of the method is a time interval of defined maximum duration, called time slice, during ...
