DESCRIPTION:Please join us for our fortnightly journal club will be online
  via zoom where two presenters will jointly present a topic together.\n\nZ

 redundancy and information-limiting correlations in cortical coding'. This
  is motivated by the recent publication of experimental results from \ntwo
  group's recordings from 100s-1000s of neurons in primary visual cortex du
 ring visual discrimination tasks:\n\n“Fundamental bounds on the fidelity
  of sensory cortical coding”\nRumyantsev et al. (Nature 2020)\nhttps://w
 ww.nature.com/articles/s41586-020-2130-2\n\n“Scaling of information in l
 arge neural populations reveals signatures of information-limiting correla
 tions”\nKafashan et al. (bioRxiv 2020)\nhttps://www.biorxiv.org/content/
 10.1101/2020.01.10.902171v1\n\n\nWe will start by discussing the relevant 
 theoretical background with a brief overview of some fundamental informati
 on theory followed by two theoretical papers that will help us better unde
 rstand the experimental results:\n\n“The effect of correlated variabilit
 y on the accuracy of a population code”\nAbbott & Dayan (Neural Computat
 ion 1999)\nhttps://www.mitpressjournals.org/doi/abs/10.1162/08997669930001
 6827\n\n“Information limiting correlations”\nMoreno-Bote et al. (Natur
 e Neuroscience 2014)\nhttps://www.nature.com/articles/nn.3807?draft=market
 ing\n\n\nAfter an overview of the theory\, we will compare and discuss the
  results in the two experimental papers as well as what this work tells us
  about the brain more generally. Those interested are welcome to have a lo
 ok at the papers in advance\, but our aim will be to provide a comprehensi
 ve overview that does not assume prior knowledge of this particular field.
