内容摘要:
To efficiently interact with exceedingly rich contents in natural vision, it is important for observers to retain precise memory representations that closely correspond to external stimuli in visual short-term memory (VSTM). The cognitive and neural mechanisms supporting precise VSTM representations have been the subject of considerable controversy in recent years. The internal noise hypothesis attributes mnemonic precision to variability of sustained neural activities that give rise to short-term retention. In contrast, we propose that VSTM storage and mnemonic precision are underlined by dissociable mechanisms. In this talk, I will summarize our recent findings that establish the contributions of the hippocampus to precision of visual memory representations using behavioral, emotion induction, non-invasive brain stimulation, translational research, and fMRI approaches.
