The role of the medial temporal lobe in memory, perception and emotion: The promiscuous hippocampus

Dr. Andrew Yonelinas, University of California, Davis

Monday, February 5 at 5:30 p.m., 118 Psychology

Abstract

Our ability to remember the important events that make up our lives is critically dependent on the medial temporal lobe (MTL). More recent work, however, has suggested that different subregions within the MTL support distinct mnemonic processes and that they play important roles in cognitive tasks beyond traditional tests of long term episodic memory. I will describe work showing that the hippocampus plays a central role in binding together and subsequently recollecting the different aspects that make up an episode or event, whereas other regions such as the perirhinal cortex can support familiarity-based memory discriminations even when recollection fails. In addition, I present evidence that the hippocampus is involved in supporting short-term memory and even visual perception, when those tasks involve high-resolution or complex bindings. I will then focus in the unique role of emotion in episodic memory and show that the amygdala supports recollection of emotional bindings that exhibit relatively slow forgetting compared to hippocampal bindings. Finally, I will examine the effects of acute stress on different MTL regions and present data showing that post-encoding stress can rescue memory from the effects of forgetting by acting as a mnemonic filter.

Prof. Jan Brascamp , as instructor of the Cognitive Psychology honors course, had an exhibition titled The Art of Psychology of Perception on display at the MSU Broad Art Lab. This was a collaboration between the Psychology department and the Eli and Edythe Broad Art Museum at Michigan State University. The exhibition was active from December 15th, 2018 until April 7, 2019. Rather than educating psychology students from utilizing a traditional art history overview, the students assessed the works on display using their own disciplinary background and perspective.
