Delayed P3 event-related potentials (ERPs) in thalamic hemorrhage

Electroencephalogr Clin Neurophysiol. 1992 Jul;83(1):52-61. doi: 10.1016/0013-4694(92)90132-2.


Delayed P3 ERPs were recorded with an acoustic oddball paradigm in 5 patients affected by unilateral thalamic hemorrhage. P3 latencies in these 5 patients were above the normal mean latency of age-matched controls +2/+3 S.D.s. The P3 delay was persistent in serial follow-ups at 6 months from stroke. Normal P3 latencies were instead recorded in 4 patients with paramedian hemorrhage not involving or only partially involving the thalamus.
