πŸ” Wisdom Unpacked

Delving deeper into the key ideas.

Neuralink, a company focused on improving brain function and overcoming clinical challenges, combines neuroscience, neurosurgery, robotics, machine learning, and computer science. They aim to augment brain function for treating disease and improving brain performance, and are exploring the peripheral nervous system and implanting devices. Their mission is to reduce human suffering, with a focus on people with terrible medical problems, and they aim to implant electrodes in the brains of quadriplegics to enable them to control a computer with their thoughts. The technology being developed is a small crack in the door that allows for the exploration of full human expansion of cognition into AI and full immersion in the internet of cognitive abilities. Neuralink is a pioneering company in this field, being public-facing and transparent about their work, and is seeking bright and motivated individuals to join their team and help patients with quadriplegia.

2. Understanding the brain's functions and vulnerabilities is key to healthy brain maintenance.

The brain, as the seat of cognition and movement, is a complex organ that can be fixed and mended. Surgeons can use techniques like heat therapy to treat brain tumors, minimizing damage to surrounding tissue. Damage to the frontal lobes can reveal their normal functioning, including the regulation of impulsive behavior. The outer portions of the brain, known as the neocortex, are responsible for mood, hormone output, and sleep, while the inner portions control reasoning and problem-solving. The skull, though a biological adaptation, is vulnerable to traumatic brain injuries, often caused by car accidents and other environmental accidents. Alcohol consumption can lead to significant brain atrophy, while substance use can increase addiction. To keep the brain healthy, it's crucial to avoid head injuries and excessive alcohol consumption.

3. Neuroplasticity is influenced by factors, with limited potential for adult brain plasticity.

Neuroplasticity, the brain's ability to change and adapt, is influenced by various factors, including species, age, and redundancy in neural circuits. While classical psychedelics and machines like implanted electrodes and computers can increase neuroplasticity, the potential for plasticity in the adult brain without machines is limited. Pharmacologic agents like psychedelics have a broad impact on plasticity, while electrical stimulation targets in the brain are focused. Neuralink's devices may have a more broad ability to steer current to multiple targets, but it is unlikely that we will see coating the entire surface and depth of the brain with electrodes in our lifetimes.

Neuralink, a company focused on brain-machine interfaces, aims to help quadriplegics walk again by reconnecting their own muscle system to their motor cortex. This involves bypassing the damaged area of the spinal cord and connecting an implant in the spinal cord to an implant in the brain. This approach has the potential to reconnect the brain to the body in the future. The company is currently focused on decoding the brain through electrical stimulation and recording, with the goal of having patients control electronic devices with their motor intentions. The transformation of electrical signals from the motor cortex to muscles is a complex problem, but Neuralink is using smarter algorithms to decode motor intentions and has achieved world records in bitrate of information coming out of a monkey's brain. However, they cannot ask the monkey what it's thinking or tell it to try different movements. With humans, they expect to accelerate the process and get more interesting results, such as decoding speech from hand movement in the brain.

The Neuralink device, initially designed for people with medical problems, is a safe and convenient technology that can be used for various functions. It is powered wirelessly by a small RFID tag implanted in the hand, which can store data and be read by a phone or other device. The procedure to implant the RFID tag is an outpatient procedure with minimal pain and no immune response. Scientists have a history of conducting experiments on themselves to understand how intention and awareness of goals can shape outcomes in biology. This type of experiment can advance technology fastest.

6. Bluetooth headphones and EMFs are safe, but precautions are advised.

Bluetooth headphones and other devices with electromagnetic fields (EMFs) have raised concerns about their safety, but the energy levels involved are not a cause for concern. Our bodies have mechanisms to deal with constant exposure to EMFs and ionizing radiation. However, it's important to be aware of the potential risks and take precautions. In terms of heat, there is some heat generated by Bluetooth headphones, but the body's cooling system is capable of regulating temperature. It's not necessary to worry about the use of earbuds or other devices in terms of heat effects on the brain.

Blind people have been using canes to navigate the world by translating visual cues into somatosensory cues. Neuralink, a device similar to a cane, uses robotics and chips to learn and adapt to changes in firing patterns of the brain. By coupling human intelligence with software intelligence, the user can improve their ability to use the device. Video games can be used as a training environment to improve motor execution and visual detection, as shown by surgeons who play video games.
