Whether to improve our cognition or as a lasts desperate attempt to survive while waiting for better bodies to replace our ailing ones, brain interfaces which allow us to communicate directly with technology are already on their way. Experiments have been performed with monkeys thousands of miles apart with one brain controlling the other monkey’s actions. At the moment it takes months of training and computer learning to determine which signals do what, but with the ever exponential increase in computing power that time will be significantly reduced in future.
So rather than asking Siri out loud how many calories in a banana, perhaps one day just thinking the question will be enough for a flood of information to appear in your mind ready for you do dive into and review?
This section will keep you up to date with the latest developments and real world examples of the continuing blurring between man and machine.

New brain implant design to restore vision to the blind – Nextbigfuture – 9-Feb-2017

The next generation of brain implant is a teeny tiny coil – Popular Science – 9-Dec-2016
The micro coils make mind-controlled prosthetics easier to use.
Most brain implants are electrode-based needing a direct contact between the metal and the brain and often become less effective over time.
Micro coils are thin metal wires with single sharp bends in them which use magnetic energy instead.
Should last longer and their directional field will allow for more fine-tuned muscle movements.
Brain implants have the potential to help people with everything from Parkinson’s disease to blindness.
First home brain implant lets locked-in woman communicate – New Scientist – 12-Nov-2016
Used at home in a person’s day-to-day life, without the need for doctors and engineers

$100 million project to make intelligence-boosting brain implant – New Scientist – 20-Oct-2016
The company, Kernel, was launched earlier this year by entrepreneur Bryan Johnson.
The first experiments planned will be on memory.
The first super-humans are those who have deficits to start with.
Johnson: “You could build a prosthetic for the hippocampus that would help restore the circuitry, and restore memory”
Plan to develop this prosthesis to enhance memory provide a cognitive boost.
COMMENT: grand plans but very early days – only just starting to record brain activity
Paralysed man feels through robotic fingers (VIDEO) – Independent – 13-Oct-2016
Robotic arm connected directly to brain of paralysed 28-year-old man.
Microelectrodes about half the size of a shirt button were surgically implanted in his brain.
He said it felt like “my fingers” were being touched or pushed.
Before the operation, imaging identified exact places that corresponded to sensations in his hand.
The ultimate goal is to create a system which moves and feels just like a natural arm would.
