DESCRIPTION:Speaker: Edvard Moser\nhosted by Peter Jonas / Maximilian Jösc
 h\nAbstract: Space and time in the brainThe ability to map space is critic
 al to survival. Without it\, we would not find food or partners\, or we wo
 uld be eaten by predators. Neural systems for finding one´s way thus exis
 t in all animals. In mammals\, space is mapped by complex neural networks 
 in a pair of brain areas called the hippocampus and entorhinal cortex. The
 se brain areas contain a variety of specialized cell types\, including gri
 d cells. Grid cells are active only when animals are at certain locations\
 , locations that tile environments in a periodic hexagonal pattern\, like 
 in a Chinese checkerboard. Grid cells keep track of our position in the en
 vironment in ways reminiscent of a GPS. I will discuss putative mechanisms
  of the grid pattern and show how space is mapped by grid cells as well as
  other specialized cells. In the last part of the talk\, I will show how t
 emporal information is encoded across scales from seconds to hours within 
 the overall population state in a neighbouring region\, the lateral entorh
 inal cortex. A similar encoding of time is not present in medial entorhina
 l cortex or hippocampal areas. When animals’ experiences are constrained
  to become similar across repeated task trials\, the encoding of temporal 
 flow across trials is reduced while encoding of time relative to trial sta
 rt is improved. In the hippocampus\, this task-dependent representation of
  time may be integrated with spatial inputs\, allowing the hippocampus to 
 store a unified representation of experience.
