Brevity of processing in a mnemonic task

摘要: 1. A burst of from one to four current pulses 0.2 ms at 100 Hz was administered bilaterally medial temporal lobe areas while monkeys worked in a delayed matching-to-sample visual memory task. The brief electrical stimulation used as probe determine when, around the 20 or 50 sample presentation, disruption most severe. 2. Stimulation within about 200 image onset severely perturbed animals' ability subsequently recognize that image. Identical other times did not. 3. Thus, processing during encoding, is accessible implanted electrodes, appears occur only interval associated with receipt sensory input.
