Holographic brain manipulation to create experiences
Inside our brain, there are nearly 100 billion neurons that are simultaneously firing 20 trillion synapses every second. Each neuron branches out and connects to other cells, and each synapse represents a different aspect of life, be it a smell, feeling, sound, sight, or otherwise. Together they dictate every action, thought, and memory within our mind.
But what if we could edit the activity within our brain? In April, researchers from the University of California Berkeley announced an essential first step toward this brave new world: they’ve created a holographic brain device that can simulate false sensations.
A paper submitted by researchers from the University of California Berkeley in October last year on “Precise multimodal optical control of neural ensemble activity” finally got published recently this year. They announced an essential first step towards creating of a holographic device in our brain which can distort and interpret reality in a completely different way, just like in “The Matrix” series.
The device works via a concept called optogenetics, which involves placing genes that produce light-responsive proteins into specific cells in the body. That way, researchers can use specially targeted light to alter the cells’ behavior.
