CLASS:PUBLIC
DESCRIPTION:Mark Reimers\, Michigan State (https://iq.msu.edu/mark-reimers/
 )\n\nLocation: E5 2004\n\nTitle: A new and inexpensive method for high-re
 solution imaging of\nneural activity across the cortex of small animals\n\
 nAbstract: In this talk I will introduce a new system for imaging the\nac
 tivity of several thousand labelled neurons distributed sparsely\nacross t
 he dorsal cortex of a mouse at high speed. The key is to use\nextensive co
 mputation to make up for the deficits of simple imaging\nsystems. I will d
 escribe the ideas behind our system and the\ntechnology that we're using t
 o implement these ideas\, at a cost of\nunder $50\,000. I will describe so
 me of the technical issues we've\naddressed\, and issues that we’re stil
 l working on. A natural\nquestion to ask is how much of the complex cortic
 al activity can be\ninferred by recording from a small fraction of neurons
  in each area. I\nwill present evidence from large-scale Zebrafish and mou
 se brain\nrecordings to suggest that a surprisingly small fraction of labe
 lled\nneurons may be sufficient to represent most of the population activi
 ty\nin the upper layers of cortex.
