摘要

最近的研究表明海马体与工作记忆(WM)有关。斯洛特尼克(本期)对相关的功能磁共振成像结果进行了批判性审查，并得出结论:WM“不会激活海马体”。我们通过讨论人类颅内和病变研究的观察来扩展Slotnick的综述。这些研究确实表明海马体对WM的贡献(超越新颖性编码)，然而传统的功能磁共振成像很难捕捉到。尽管如此，新的功能磁共振成像技术的出现，以及对短期和长期记忆中共享的海马机制的更强强调，为未来铺平了令人兴奋的道路。

Hippocampal activity in working memory tasks: sparse, yet relevant.

Recent studies suggest the hippocampus is involved in working memory (WM). Slotnick (this issue) critically reviewed relevant fMRI findings and concludes WM 'does not activate the hippocampus.' We extend Slotnick's review by discussing observations from human intracranial and lesion research. These studies do suggest hippocampal contributions to WM (beyond novelty encoding), which however are difficult to capture with conventional fMRI. Still, the advent of new fMRI techniques combined with a stronger emphasis on shared hippocampal mechanisms across short- and long-term memory pave an exciting path forward.

期刊介绍： Cognitive Neuroscience publishes high quality discussion papers and empirical papers on any topic in the field of cognitive neuroscience including perception, attention, memory, language, action, social cognition, and executive function. The journal covers findings based on a variety of techniques such as fMRI, ERPs, MEG, TMS, and focal lesion studies. Contributions that employ or discuss multiple techniques to shed light on the spatial-temporal brain mechanisms underlying a cognitive process are encouraged.
