Avatar is all about EEG

In a sense, AVATAR is a manifesto of the power and possibilities of EEG. Was James Cameron inspired by EEG?

"the neurons are the cells which controls our whole body. And for example you can see it in visual that is the movie AVATAR. Actually when I saw that movie, I could feel the imaginations and creativity only, but when I read about the neurons, then I understood that the concept of movie was all about the neurons and its working has been shown tremendously in the movie."

The technology of using brain to control an avatar in video games are emerging. Then, the term 'Avatar' may have another meaning.

Dynamic Clamp

The use of channel blocking drugs to study different ion channels makes one wonder if there is a less destructive manner to study channel behavior. The Dynamic clamp provides just that.

The Dynamic clamp is an evolution of the voltage clamp which can be used to simulate dynamic processes such as membrane of synaptic currents in living cells.The operation is as follows:

A living cell is contacted with one or several electrodes and its membrane potential V is amplified and fed into the dynamic clamp machine. The dynamic clamp machine contains a model of the membrane or synaptic conductance(s) to be inserted in the living cell(s), either in the form of equations (for digital dynamic clamp systems) or in the form of a dedicated electrical circuit (for analog systems). The dynamic clamp system computes the current(s) I generated by the modeled conductance(s) and outputs it in real-time. That current is injected into the living cell, which therefore receives the same current as if it contained the membrane or synaptic conductance modeled with the dynamic clamp.

EKG simulator

Great way to learn how to read an EKG.


Exoskeletons supplement human movement by reading EMG signals to determine the intent of the user:
