Neuralink's second brain implant operation, after several delays and radio silence for weeks, has been a success, according to CEO Elon Musk.

In a podcast last Friday, Musk shared that the eight-hour operation was a success as the patient, who suffered a spinal cord injury, was able to use 400 out of the 1,024 electrodes in the implant.

This is at the same level of electrodes being used by Neuralink's first patient, Noland Arbaugh, who Musk claimed had "roughly 10, 15% of the electrodes working."

Latest details on the second brain implant patient were first reported by Reuters.

Musk did not provide further information on the surgery to protect the patient's privacy, although Neuralink is expected to provide more details as soon as the patient has fully recovered.

Neuralink has previously postponed its second brain implant surgery after its first candidate exhibited health issues.

Musk later claimed that the company and its partnered health institution have already selected a new candidate with the surgery happening "next week." The statement was made in early July.

Neuralink to Ramp Up Brain Implant Surgeries in 2024

With the second brain implant touted as a success, Neuralink and Musk now pose to ramp up surgeries in the coming months after securing regulatory approvals.

Musk earlier signaled that the company is looking to complete at least eight brain implant surgeries this year as more potential candidates apply for Neuralink's human test operations.

The company has even reported having improved its brain implants' electrodes to prevent a huge decrease in the number of effective electrodes as it did on Arbaugh a few months after his surgery.
