‘Matrix’-like brain training to speed up physical therapy possible in the future

Neurological-brain

It’s no easy task to learn to walk again after a traumatic accident. One of the hardest things for motor-impaired patients is to generate the correct brain signals to help them recover efficiently.

Paralyzed man first to walk using brain power alone

brain

A paralyzed man is able to move using his brainpower thanks to a  ‘neural-bypass procedure’ that has been heralded a world first. Neurosurgeons achieved the world first by transmitting signals from the 26-year-old American’s brain to electrodes placed around both knees.

Why electronic brain stimulation is trending right now

brain

There seems to be no end to the benefits of electronic brain stimulation. Focused thinking, better memory, deeper sleep, relief from depression, reduced stress are among some of the benefits you read about on the internet. In particular, a technique called transcranial direct current stimulation is getting loads of attention from early adopters who rave about its potential and scientists who are trying to unravel what it can and cannot do.

Comparing brain vs deep learning and the computational complexity of these processes

14599057004_9dc53af6f9_z

Tim Dettmers: In this blog post I will delve into the brain and explain its basic information processing machinery and compare it to deep learning. I do this by moving step-by-step along with the brains electrochemical and biological information processing pipeline and relating it directly to the architecture of convolutional nets. Thereby we will see that a neuron and a convolutional net are very similar information processing machines. While performing this comparison, I will also discuss the computational complexity of these processes and thus derive an estimate for the brains overall computational power. I will use these estimates, along with knowledge from high performance computing, to show that it is unlikely that there will be a technological singularity in this century.
