Does the somatosensory temporal discrimination threshold change over time in focal dystonia? [PDF]
, 2017 BACKGROUND: The somatosensory temporal discrimination threshold (STDT) is defined as the shortest interval at which an individual recognizes two stimuli as asynchronous. Some evidence suggests that STDT depends on cortical inhibitory interneurons in the
