similarly to neurons, brain
implant represents itself in
consciousness
Expanding experience

Synthetic qualia? but is it possible for artificial device
to create consciousness?
artificial neural network modelshave been already developed
which demonstraterudimentary consciousness or some
aspects of consciousness
Edelman brain-based devices
neural networks simulations byDehaene, Gamez

Putting them togetherhow to integrate synthetic qualia
with those produced by brain?
learn from nature!
color
shape
motion
sounds
so how does brain bring them all together?

The miracle of broadcastInformation Integration
TheoryTononi & Edelman
•differentiation consist of many specialized modules•integration each
module profoundly affects activity of others•consciousness can be
measured mathematically
Global Neuronal Workspace Theory

•many specialized modules•integration/
broadcasting via subset of special workspace neurons
what makes the system conscious?

The hardwarehow to make the implant broadcast?
today’s brain-machine interfaces
electrode gridX only those neurons close to the surface
DBS electrode
X many connections
are not possible:•can
damage everything•procedure
too cumbersome

The hardwarea new hopes
“sprouting” brain-machine interfaces
Harnessing the blood supply network (R.
Llinas)
Growing up your own network of
neuroagents
![Page 18: Brain-Computer Interfacing, Consciousness, and the Global Brain: Towards the Technological Enlightenment](https://reader033.fdocuments.us/reader033/viewer/2022061300/54c781334a795934358b459d/html5/thumbnails/18.jpg)
neurons are grown on a
chip
their axons grow through
the brain
intermediate layer
between brain and
electronics
communication channel is natural
for the brain
The hardwareinterfacing in a brain-friendly way
![Page 19: Brain-Computer Interfacing, Consciousness, and the Global Brain: Towards the Technological Enlightenment](https://reader033.fdocuments.us/reader033/viewer/2022061300/54c781334a795934358b459d/html5/thumbnails/19.jpg)

![Page 20: Brain-Computer Interfacing, Consciousness, and the Global Brain: Towards the Technological Enlightenment](https://reader033.fdocuments.us/reader033/viewer/2022061300/54c781334a795934358b459d/html5/thumbnails/20.jpg)
Applicationsapproach to “cracking neural code”
conscious neural implants provide a fresh approach to the problem of transferring
information into the brain
1. transfer happens when brain-implant system becomes conscious
2. a mathematical tools for analyzing conscious systems are being developed
3. these tools finally allow to calculate optimal design for the implant enabling consciousness = information transfer
![Page 21: Brain-Computer Interfacing, Consciousness, and the Global Brain: Towards the Technological Enlightenment](https://reader033.fdocuments.us/reader033/viewer/2022061300/54c781334a795934358b459d/html5/thumbnails/21.jpg)
Going furtherexploring the minds of Others
would it be possible to join conscious
experience of another being with yours?
the major difficulty is provided by functional
aspects of consciousness
![Page 22: Brain-Computer Interfacing, Consciousness, and the Global Brain: Towards the Technological Enlightenment](https://reader033.fdocuments.us/reader033/viewer/2022061300/54c781334a795934358b459d/html5/thumbnails/22.jpg)
Going furtherthe Consciousness Singularity
all consciousness on the planet, living and artificial, merged to a
single one
the “functional problem” disappears at the global level

The end?nop, just the beginning!
