Meeting for Multidimensional Analysis of Memory Mechanisms
Venue: Centre Broca
Organized by Laurent Groc & Naoya Takahashi (IINS)
The meeting is open to all UB and Neurocampus members. No registration is required if you only wish to attend the talks (without lunch or dinner).
What is MAMM?
Multidimensional Analysis of Memory Mechanisms (MAMM) is an international consortium on memory research, funded by KAKENHI (Japan). It supports scientific exchange between labs in Japan, Bordeaux, and the MPI Florida.
