Welcome to the IEEE-EMBS-Summer-School-of-Neural-Engineering-2018 http://mindreading.technology/

Tsinghua University, Beijing, China, 13 August - 17 August, 2018


*All images, videos, scritps, files from the summer school lectures or professor

The code from the prof.Yijun Wang, the code is used for EEG data analysis


The First day, 13 August,2018

Part 1 Mind reading technology

A. ALS B. Movement neural C. SCL(Spinal cord injury)

Brain computer interface

Brain- Neural signal- Computer - devices

Why we do mind reading?

Crack the brain code

Neural signal from electrotechnology

How many the spikes from the neural(Encode and Decode)

spike signal, temporal signal

Decoding/Mind reading(Categories)

a. Reconstruction b. Identification c. Classification

Electrical signal from the brain(fMRI, EEG, MEG)

The Category of BCI

Visual pathway of BCI 10 Monkey M1 coding of Movement direction

Population Vector Decoding

BrainGate and Wireless techniques.

Ultrasonic Neural Dust(2017, Program)

The challenge of BCI: Read out and Write in

Memory research


Part 2 Optical Neurovascular Imaging and Ultrasound Stimulation of the Brain https://scholar.google.com/citations?user=tz4TKL0AAAAJ&hl=en

Laser speckle imaging and Ultrasound stimulation techniques.


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 4 Blackrock http://blackrockmicro.com/


The Second day, 14 August, 2018

Part 1 Based EEG of Mind reading

http://sourcedb.semi.cas.cn/zw/rczj/yjsds/201508/t20150819_4412940.html

part 2 Oral and poster presentation


The Third day, 15 August, 2018


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.
