Introduction to Cybernetics in Edgerunners [0:00]

The Cyberpunk Edgerunners universe features characters who upgrade their bodies with cybernetic implants, leading to varying outcomes. Dr. Maddie, a UK doctor, analyzes the science behind these implants, focusing on the character David's transformation. The video also covers cyberpsychosis and immune modulators.

Neck Chip Implants and Nerve Stimulation [1:01]

The series shows characters with neck slots for chips that grant preset movements, similar to "Kung Fu" uploads.

• Mechanism: For such chips to work, they would need access to the spinal cord and peripheral nervous system to control limbs.
• Real-world comparison: While not as sophisticated, real-world nerve stimulators exist to restore function in patients with stroke, nerve damage, or Parkinsonism, by causing muscles to contract.

  

• Limitation: Current technology is far from enabling complex, preset combat movements.

David's Spinal Implant (Sandevistan) and its Effects [2:20]

David acquires a full bionic spine, the Sandevistan, which enhances his reflexes and speed.

• Advantages of a bionic spine:
  • The spine acts as a highway for electrical signals from the brain to the body.
  • Unlike organic structures that degrade with age, a bionic spine could maintain or even increase the efficiency and speed of signal transmission.
  • This could lead to quicker reaction times and reduced time loss between thought and action.

    

• Physical limitations:
  • Moving at extreme speeds, as seen in David's "bullet time" mode, demands immense oxygen and nutrient supply to muscles, which the human circulatory system may not sustain.
  • Muscles can perform anaerobic respiration for short bursts but lead to lactic acid buildup, requiring a robust circulatory system for recovery.
• Brain overload:
  • David frequently collapses due to his brain being overwhelmed by the new spinal implant, likened to a computer crashing from excessive demands.

    

  • The brain receives feedback signals from the body for recalibration, and a super-powered spine would generate an overwhelming amount of information.
  • Prolonged exposure to such high signaling could cause mental breakdowns and permanent brain damage, necessitating a bionic brain to process the information.

Immuno-Modulators and Immune System Response [5:34]

To tolerate cybernetic implants, characters in Cyberpunk Edgerunners use immune modulators.

• Function: These drugs suppress the body's natural immune response, which typically identifies and attacks foreign objects like implants.
• Mechanism: The immune system is constantly on alert for anything it deems "not belonging," such as foreign proteins, bacteria, or foreign bodies, and activates defense mechanisms to eliminate them.

  

• Real-world application: Immuno-modulators are real drugs used by patients who have received organ transplants or are being treated for chronic inflammatory conditions.
• Dosing challenges: In the real world, precise dosing is crucial and monitored with regular blood tests to ensure the body tolerates the implant without suppressing the immune system to a dangerous level, leaving the patient vulnerable to infection. David, however, seems to lack this oversight.

Cybernetic Lungs and Circulatory System Needs [7:14]

David opts for cybernetic lungs to enhance his oxygen intake and exercise tolerance, aiming to extend his "bullet time" capabilities.

• Lung benefits: Improved oxygenation allows for longer periods of activity and better anaerobic respiration.

  

• Systemic needs: The doctor emphasizes that a heart upgrade would also be necessary to efficiently pump super-oxygenated blood to muscles and remove waste products like lactic acid, which accumulate during prolonged anaerobic activity.

  

The Onset of Cyberpsychosis [8:51]

As characters accrue more implants, they show detrimental neurological effects, including tremors and disorientation.

• Causes of tremors: Can be due to insufficient dopamine, abnormal reflex pathways, or high levels of metals in the bloodstream.
• Wilson's Disease parallel: A real medical condition, Wilson's disease, involves high levels of copper (a metal) in the blood, which deposits in the brain and liver, causing neurological symptoms like tremors and psychosis.

  

• Definition of Psychosis: Psychosis is a severe mental disorder where thoughts and emotions are so impaired that one loses contact with external reality.

  

• Maine's case: Maine, another character, succumbs to cyberpsychosis, becoming detached from reality. This is attributed to a combination of factors:
  • Side effects from immune modulators.
  • Brain overload from cybernetics.
  • Potential metal seepage from implants into the bloodstream.

Maine's Cybernetic Arms and Signal Speed [10:47]

David, becoming the group leader, integrates Maine's cybernetic arms.

• Mechanical advantage: These arms likely operate on wires rather than nerves, offering significantly faster signal transmission.
  • Nerve signals: ~50 meters per second.
  • Electrical signals over wires: 90% the speed of light (250,000 kilometers per second).
• Functional consequence: This speed allows David to better keep up with his "bullet time" abilities, overcoming the previous limitations of his organic nervous system. He also integrates lower limb implants for mechanical consistency.

  

David's Cyberskeleton and Final Stages of Cyberpsychosis [13:02]

David installs a full cybernetic skeleton, gaining immense weaponry and power.

• Increased burden: This further intensifies the load on his nervous system and remaining human parts, pushing him closer to cyberpsychosis.
• Immuno-modulators as a temporary fix: The immuno-modulators become the only thing providing temporary consciousness, but at an increasingly dangerous dose (9 times the usual).

  

• Medical dosage principle: Doctors work within a "safe therapeutic window." Too little is ineffective; too much risks severe side effects and overdose, comparable to taking nine times the dose of paracetamol.
• Irreversible decline: The doctor warns that these high doses are the last resort, and David will not return to sanity, losing his humanity due to overwhelming physical and mental burden, eventually hallucinating.

Adam Smasher and the Limits of Human Modification [16:04]

Adam Smasher, a fully cybernetic villain, is presented as David's potential future if he completely abandons his humanity.

• Full cyborg benefits: A fully cybernetic being, especially with a bionic brain, would think in a binary fashion, unhindered by human emotion or indecisiveness.
• David's fate: David's ultimate end, battling Adam Smasher, is seen as an inevitable outcome of excessive body modification without fully replacing organic parts. The video concludes by pondering the ethical and medical line between beneficial cybernetics and losing one's humanity.
