Neuralink

In News 
  • Elon Musk founded the Neuralink startup in 2017 with the goal of staving off what he considers to be an “existential threat”: artificial intelligence (AI) surpassing human intelligence.
Nuralink 
  • Neuralink is a gadget that will be surgically inserted into the brain using robotics by neurosurgeons.
  • In this procedure, a chipset called the link is implanted in the skull.
  • It has a number of insulated wires connected from the electrodes that are used in the process.
  • This device can then be used to operate smartphones and computers without having to touch it. 
Working 
  • The brain consists of neurons that transmit signals to cells in the body including muscle, nerve, gland and other neuron cells.
  • Every neuron is made up of three parts called the dendrite, the soma (cell body) and the axon. Each of this part has its own function.
  • The dendrite receives the signals. The soma processes these signals. The axon then transmits the signals to the other cells.
  • The neurons are connected to one another by the synapses which release neurotransmitters.
  • These chemical substances are then sent to another neuron cell’s dendrite causing the flow of current across the neurons.
  • The electrodes that are part of the Neuralink will read electrical signals that are produced by several neurons in the brain.
  • The signals are then outputted in form of an action or movement. 
Benefits 
  • Neuralink can be used to operate encephalopathy.
  • It can also be used as a connection between the human brain and technology.
  • This means that people with paralysis can easily operate their phones and computer directly with their brain.
  • Its main purpose is to help people to communicate through text or voice messages.
