Our nervous system processes all the sensory information that our organs receive and converts it into electrical and chemical signals that go to the brain and spinal cord. Memories are formed by specific chains of neurons that represent a particular experience, which leads to the bias in the likelihood that the same neurons will be activated in the same sequence again and again.
By incorporating a light source as simple as a transistor onto a silicon chip, processors could communicate through light above a certain distance. Though optical fibers currently utilize visible or near infrared wavelengths of light for transmitting messages, the potential for neuron-like flexibility with a small light source can revolutionize future communication systems.
The human mind is limited in its perception of reality, only able to perceive less than 1% of what's actually real. The coherent alpha state can allow individuals to tap into their inner world, which can become more real than their external world.
The speaker highlights the importance of understanding our mind and higher faculties, which can help us experience marvelous things. The speaker also mentions studying the mind, which is not limited to psychiatrists, psychologists, or behavioral scientists.
Humans can train their brains to navigate a three-dimensional world based on sound and ricochets, allowing for visual perception outside of their immediate surroundings. The perception of reality is based on the maps we create from our senses, and with synesthesia, the brain can reinterpret and expand that reality.
The challenge in brain computer interfacing lies in controlling a highly structured and non-linear system that is relevant to our lives and rests upon non-equilibrium dynamics, similar to weather patterns or active matter. The plastic potential of the brain allows it to remodel and augment sensory data, and the free energy principle plays a role in understanding its function in terms of inference.
