Multiscale modeling of the dependencies between spikes and fields -Hamidreza Abbaspourazad, Maryam M. Shanechi
Data Analysis
Learning the dependenciesMotivation & Introduction
Future Work
• Recent advances in technology has allowed
us to access multiple spatiotemporal scales
of brain activity at the same time.
• Multiscale model
Behavior Brain state
Hidden state
LFP observation
Spike observation
Add LFP to spikes Add spikes to LFP
Incorporate the
dependencies
Decrease model
complexity
Kernel smoothing

EM
algorithm
• Apply this method on real data to better understand
the dependencies between spike and fields
Conditionally independent
