The brain-reading devices helping paralysed people to move, talk and touch

June 11, 2022

Finally, there is widespread acknowledgement that ethical oversight must keep pace with this rapidly evolving technology. BCIs present multiple concerns, from privacy to personal autonomy. Ethicists stress that users must retain full control of the devices’ outputs. And although current technologies cannot decode people’s private thoughts, developers will have records of users’ every communication, and crucial data about their brain health. Moreover, BCIs present a new type of cybersecurity risk.

Great article. Amazing technology. But I am worried about the long-term #privacy implications of real mind-reading devices.

Thought experiments Amazing progress in Brain-computer interfaces (#BCIs): paralyzed patients manipulating silverware. Communicating w/ “locked-in” individuals. Will this scale?

Brain-computer interfaces sound like the stuff of science fiction. Andrew Palmer sorts the reality
from the hype

IN THE gleaming facilities of the Wyss Centre for Bio and
Neuroengineering in Geneva, a lab technician takes a well plate out of an incubator. Each well contains a tiny piece of brain tissue derived from human stem cells and sitting on top of an array of electrodes. …
To see these signals emanating from disembodied tissue is weird. The firing of a neuron is the basic building block of intelligence. ..

This symphony of signals is bewilderingly complex. There are as many as 85bn neurons in an adult human brain, and a typical neuron has 10,000 connections to other such cells. The job of mapping these connections is still in its early stages. But as the brain gives up its secrets, remarkable possibilities have opened up: of decoding neural activity and using that code to control external devices.
