Hello,

We are going to have another math-neuro presentation next week, on
Tuesday Oct 9th, from 14h00-15h00 in room 4106. The presentation will be
by Jean-Phillippe Thivierge, who is briefly visiting from Indiana (I
apologize for doing this on a Tuesday before the "travaux récents", but
it was the only possible time). Here's an abstract:

"How Random is Brain Activity?"


"Neurons of several regions of the brain, including hippocampus and
cortex, have a tendency to spontaneously alternate between states of
activity and quiescence at non-periodic, seemingly random times. Despite
the ubiquitous nature of this phenomenon across species and protocols,
the mechanisms responsible remain largely unknown. Using computer
simulations, we show that spontaneous synchronization can emerge
naturally from completely deterministic cellular interactions, without
randomness. Noise-free simulations capture the Poisson-like distribution
of both spontaneous and evoked activity recorded in acute CA1 slices of
hippocampus, and suggest new experiments and their expected outcome.
This talk is hoped to generate some interesting discussions among
neurophysiologists and modelers."



Regards,

Paul
