[Neuro] [Fwd: my talk this wednesday]

[Stan Osborne]

Gautam is a 'brain' researcher on his way to a research lab in Europe
after 11 years at UCB working his way up the lab rat food chain.

Hopefully this is distributed to the mailing list before the talk is over.

Hey Stan,

Hope all is well. I recall that I promised you details for my talk this
week, in case it is of interest to the Noisebridge folks working on
EEG-based decoding. Any of them are welcome to join.

Unsolved Mysteries of Hippocampal Dynamics

Wednesday 23rd of July 2014 at
12:00pm
560 Evans, UC Berkeley

Two radically different forms of electrical activity
can be observed in the rat hippocampus: spikes and local field potentials
(LFPs). Hippocampal pyramidal neurons are mostly silent, yet spike
vigorously as the subject encounters particular locations in its
environment. In contrast, LFPs appear to lack place-selectivity, persisting
regardless of the rat's location. Recently, we found that in fact one can
recover from LFPs the spatial information present in the underlying
neuronal population, showing how these two signals are two sides of the
same coin. Nonetheless, there are many aspects of the LFP that remain
mysterious. I will review several observations and explanatory gaps which
await further study. These include: the relationship of LFP patterns to
anatomy; the elusive structure of gamma waves; complex forms of
cross-frequency coupling; variations in LFP patterns seen when the rat
explores its world more freely; reconciling the memory and navigation roles
of the hippocampus.
