DESCRIPTION:The 2021 Herbert Jasper Lecture will be delivered by Bruce L. M
 cNaughton\, AIHS Polaris Research Chair at the University of Lethbridge\, 
 Canada. His lecture is entitled ’Zipping’ and ‘unzipping’ the hippocampal 
 index. \n\nThe Neuro's Herbert Jasper Lecture was established in 1989. Dr.
  Jasper\, who passed away in 1999\, worked together with Wilder Penfield a
 t The Neuro during his early and very seminal years (1937-1964) and remain
 ed associated with the Institute for the remainder of his career and life 
 in Montreal. This lectureship\, which is focused like the work of Jasper u
 pon Neurophysiology was instituted in his honor.\n\nRegistration is availa
 ble here.\n\n\nTalk Abstract\n	There is a long-standing tension between the
  notion that the hippocampal formation is essentially a spatial mapping sy
 stem\, and the notion that it plays an essential role in the establishment
  of episodic memory and the consolidation of such memory into structured k
 nowledge about the world. One theory that resolves this tension is the not
 ion that the hippocampus generates rather arbitrary 'index' codes that ser
 ve initially to link attributes of episodic memories that are stored in wi
 dely dispersed and only weakly connected neocortical modules. I will show 
 how an essentially 'spatial' coding mechanism\, with some tweaks\, provide
 s an ideal indexing system and discuss the neural coding strategies that t
 he hippocampus apparently uses to overcome some biological constraints aff
 ecting the possibility of shipping the index code out widely to the neocor
 tex. Finally\, I will present new data suggesting that the hippocampal ind
 ex code is indeed transferred to layer II-III of the neocortex.\n\n \n
