We are excited to have an online seminar by Prof. Gabrielle Girardeau from CRCN Inserm. Everyone is welcome to join the seminar!
Neural mechanisms for memory and emotional processing during sleep
The hippocampus and the amygdala are two structures required for emotional memory. While the hippocampus encodes the contextual part of the memory, the amygdala processes its emotional valence. During Non-REM sleep, the hippocampus displays high frequency oscillations called “ripples”. Our early work shows that the suppression of ripples during sleep impairs performance on a spatial task, underlying their crucial role in memory consolidation. We more recently showed that the joint amygdala-hippocampus activity linked to aversive learning is reinstated during the following Non-REM sleep epochs, specifically during ripples. This mechanism potentially sustains the consolidation of aversive associative memories during Non REM sleep. On the other hand, REM sleep is associated with regular 8 Hz theta oscillations, and is believed to play a role in the regulation of emotional reactions and the consolidation of emotional memories (emotional processing). Unraveling the fine neuronal dynamics related to REM sleep, Non-REM sleep and the transitions between states in the hippocampus-amygdala network will further our understanding of the implication of these sleep stages and related brain patterns in emotional processing.

Are you using environmental DNA (eDNA) in your research? Or are you just curious about eDNA and its potential applications? Please join us for this inter-unit meeting about eDNA research at OIST. Speakers from Ravasi, Husnik, N. Luscombe, Miller, and Satoh units will first briefly introduce their eDNA research projects and then we will have a roundtable discussion to share our expertise across units.
