Part 3 Brain Computer Interface
For brain computer interface, more information and device that you can find Blackrock
they develop a lot of tiny device that make brain computer interface more fast and safe.

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)
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.
Decoding of Auditory Perception
