How Fast Can Neuralink Read the Brain? Speed Breakdown

• Neuralink participants reached a brain-computer interface record of 11.32 bits per second in 2026, and the median participant is at about 10 bits per second.
• Patient Noland Arbaugh (@ModdedQuad) once held the record and was later surpassed by other participants, who use the cursor for gaming, browsing, and work.
• Neuralink's roadmap targets about 10,000 channels in 2027, which would give decoders much more information to work with.

Bits per second: the key speed metric

Neuralink measures reading speed in bits per second (BPS), which captures how much information a user can send through a task like moving a cursor to targets. Able-bodied people using a mouse average about 8 to 10 BPS on the same test.

The N1 implant samples neural signals across 1,024 electrodes thousands of times per second. That raw stream is huge, and software reduces it to the commands the user intends. Elon Musk describes this as the foundation for high-bandwidth links, with spikes from motor cortex neurons carrying intent.

Participants have streamed over 50,000 hours of neural data, according to Neuralink's October 2026 update, which reports the 11.32 BPS record (the previous record was 10.39) and a median of about 10 BPS.

Patient results

Noland Arbaugh, the first implant recipient, reached about 8 BPS within months of his January 2024 surgery and later set a record of 9.5 BPS. He plays chess, browses Reddit, and studies neuroscience by thought. Early thread retraction cut his usable channels, but software updates restored and then raised his speed.

RJ hit 7 bps on day one. UK patient Paul controlled a cursor hours after his implant in October 2025. Alex Conley, in the CONVOY Study, controls robotic arms. In November 2025, Elon Musk shared a report that Noland hopes to receive a second implant below his spinal injury to help restore leg movement.

How the speed is achieved

The R1 robot inserts the threads a few millimeters into the cortex (64 threads in early implants and 128 thinner threads in later ones). Chips on the implant filter noise and detect spikes. Decoders map the spikes to movements, and Neuralink's 2026 decoders were pretrained on participants' combined data, which cut calibration time for some users from about 10 minutes a day to 10 minutes a week.

After changes made following Noland's surgery, Neuralink reported higher signal quality in 18 of the next 20 participants and says it is still improving thread retention.

Human limits

Researchers at Caltech have estimated that human behavior, from typing to speaking, runs at about 10 bits per second. Neuralink's median participant now matches that rate. Neuralink's roadmap called for about 3,000 channels in 2026, and a 3,000-channel implant was disclosed in September 2026.

What comes next

The roadmap targets about 10,000 channels in 2027 and 25,000 in 2028, along with multiple implants per person. Musk ties higher bandwidth to his goal of people working closely with AI. Jon Noble, a UK participant, wrote in December 2025 that more than 10,000 people were on the US waiting list.
