Part 1 EcoG-Based Neurophysiology http://www.schalklab.org

Neuronal Populations

Which Task-related parameters does a small population of neurons encode?

Sensory input ---- Motor output

The two EcoG signal

Oscillatory activity vs Population-Level activity(neurons Firing)

Low Frequency band(10Hz-20Hz) vs High Frequency band

Relationship of EcoG Gamma with fMRI

what's the signals meaning?

"""Broadband Gamma is an index of Cortical excitability"""

what's the alpha signals mean?

Ans: alpha power rate more higher, the firing neural rate decrease.

Modulation of Excitability with Oscillatory Phase

"""The function - Through Biased Oscillations(FBO) hypothesis"""

"""Voltoge=== Excitability"""

More alpha less Gamma signals. (Biased Oscillations)

tuning function of neurons

Part 2 Engineering advanced with EcoG

BCI2000 Software(real time signal acquires, C++)-- http://www.schalklab.org/research/bci2000

and Prof.Gerwin Schalk do did a lot of interesting experiments and very impressive talk in the summer school. also you can find more useful academic papers and amazing softwares in his Lab website.
