let’s enrich this experience with new technologies!

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 broadcast
Information Integration Theory
Tononi & Edelman
• differentiation consist of many specialized modules• integration each module profoundly affects activity of others• consciousness can be measured mathematically
Global Neuronal Workspace Theory
Dehaene
• 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 electrodeX 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 - Alexandra Elbakyan - H+ Summit @ Harvard](https://reader033.fdocuments.net/reader033/viewer/2022051412/54c7813a4a7959681b8b4610/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 - Alexandra Elbakyan - H+ Summit @ Harvard](https://reader033.fdocuments.net/reader033/viewer/2022051412/54c7813a4a7959681b8b4610/html5/thumbnails/19.jpg)
Applicationsartificial bodies
tactile and proprioceptive
feedbackfor neuroprostheses
![Page 20: Brain-Computer Interfacing - Alexandra Elbakyan - H+ Summit @ Harvard](https://reader033.fdocuments.net/reader033/viewer/2022051412/54c7813a4a7959681b8b4610/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 - Alexandra Elbakyan - H+ Summit @ Harvard](https://reader033.fdocuments.net/reader033/viewer/2022051412/54c7813a4a7959681b8b4610/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 - Alexandra Elbakyan - H+ Summit @ Harvard](https://reader033.fdocuments.net/reader033/viewer/2022051412/54c7813a4a7959681b8b4610/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!
Thank you!
