Neuralink Trial Enables Quadriplegic to Write Name by Thought

The milestone validates telepathic computer control, ushering in broader trial enrollment.

The handwriting was produced by Audrey Crews—paralyzed for over 20 years—using only her thoughts through Neuralink’s brain-computer interface.

Overview

  • Audrey Crews, identified as patient P9, used her Neuralink implant to type her name purely through thought for the first time in 20 years.
  • The coin-sized N1 device was implanted under her skull with 128 ultra-thin threads in her motor cortex to detect neural signals and transmit them wirelessly.
  • Neuralink achieved its first same-day dual implant surgeries by placing chips in both P8 and P9 during a single clinical session.
  • Crews emphasized that the implant enables digital interaction only and does not restore muscle movement or walking ability.
  • Neuralink is expanding its PRIME human trial, refining implant performance and moving toward a 2030 commercial launch of its Blindsight vision-restoring chip.
