Behind the Brain Chip: An Inside Look at Blackrock Neurotech

Main summary

Key takeaways

Technology

BlackRock Neurotech / BCI overview (Salt Lake City HQ visit)

The video presents BlackRock Neurotech’s implantable brain-computer interface (BCI) technology, noting that their devices have been implanted in dozens of people since the early 2000s and used in major BCI research, including:

  • Neural prosthetics control
  • Sensory restoration / feedback to the brain (helping users “feel” via prosthetics)
  • Speech encoding/decoding and related advanced BCI functions
  • Direct communication/control tasks such as sending emails/texts and playing video games

Utah Array as flagship implant (historical + impact)

  • Origins: In 1989, Richard A. Norman (University of Utah) filed a patent for the Utah array.
  • Key technical claim: The Utah array enabled reliable 3D neural signal recording.
  • Early validation: By the late 1990s, it was used in primates to move a cursor, described as a watershed moment.
  • Milestone in 2004: Matt Nagel became the first person to have a Utah array BCI implant, associated with the “RaintGate” project (mentioned in subtitles).

From research to real-world medical device (BlackRock founded)

  • In 2008, Marcus Gerhart and Florian “Soulsbacher” (as transcribed) founded BlackRock Microsystems (later BlackRock Neurotech).
  • Their focus was medical use for paralysis, supported by acquired IP from Cyber Kinetics and others.
  • The video frames growth as a combined effort across engineering, collaboration with the neuroscience community, and translational deployment.

Beyond “100 channels”: more channels in practice

  • The Utah array is commonly described as a “100-channel” device, but the video emphasizes that many patient setups use multiple devices, resulting in ~400 channels or more.
  • In non-human primates, systems were described as reaching ~1000 channels.

System architecture: what parts of the BCI matter

The video stresses that converting brain signals into usable outputs requires multiple components:

  • Neural signals include:
    • Action potentials (neuronal “firing”)
    • Local field potentials (LFPs), extracted via different frequency band analysis
  • The implication is that spike rates plus LFPs provide a richer representation of cortical activity.

Electronics and data pipeline (described as hardware flow)

  • Head stage (“NeuroPlex E”): screws onto the Utah array pedestal; converts analog signals into digital ones and zeros.
  • Data transmission: digital data is sent via HDMI cable to digital hubs.
  • Fiber optic link: digital hubs convert the signal for fiber optic transmission.
  • Neural Signal Processor (NSP): performs core processing (“magic”), including:
    • Spike detection
    • Thresholding (a red-line threshold is shown)
    • Spike sorting into neural units (subtitles note built-in spike sorting methods)

Spike processing concept (tutorial-like visualization)

The video includes a visualization showing how, for a single channel, the NSP uses a threshold to extract spikes and then sorts them into units—highlighting that software-based processing is central to turning raw recordings into usable features.

Materials / fabrication expertise (engineering emphasis)

A speaker highlights fabrication processes tied to semiconductor microfabrication for Utah array electrodes, including:

  • Photolithography
  • Wet etching
  • Plasma etching

This is presented as core capability for fabricating the electrode structures (transcribed as “utahries”).

Clinical timeline + long-term efficacy claims

The video cites large-scale experience:

  • 32 BCI “Pioneers”
  • Over 30,000 patient days

It also emphasizes longevity:

  • Human use stated as ~8 years
  • Non-human primates stated as over 10 years

These are presented as evidence of durable functionality.

Training and application examples (patient stories / demonstrations)

  • Nancy / piano restoration: describes training where she controls a cursor toward highlighted targets via thought.
  • Jan / neuroprosthetic arm control: subtitles describe expert control by 2012, including grabbing objects of different sizes, and assistive feeding.
  • A quote-style narrative describes feeding herself (e.g., chocolate, string cheese, red pepper).

Next-generation interface: “Neuralace” (forward-looking product feature)

The company’s upcoming interface—announced around mid-November 2022 (Society for Neuroscience conference)—is the Neuralace.

Technical description:

  • A flexible hexagonal mesh that conforms to the brain surface
  • Initial configuration: ~10,000 electrodes
  • Designed to scale to more electrodes over time
  • Claimed advantages: improved biocompatibility, scalability, and better data quality than previous interfaces

Availability: expected for researchers in 2024.

Disclosure / format

  • The video explicitly states it is sponsored.
  • It also states the presenter does ongoing consulting work for BlackRock.
