Endovascular deep brain stimulation: Investigating the relationship between vascular structures and deep brain stimulation targets www.sciencedirect.com May 15, 2024, 2:30 p.m.
Endovascular brain stimulation using ‘stentrodes’ constitutes an appealing alternative to conventional deep brain stimulation. Success of endovascular stimulation will greatly depend on accurate targeting. The relationship between neurovascular structures and established surgical targets is poorly characterized to date. We investigated the neuroanatomical relationships between conventional DBS targets and associated vascular sites. Endovascular stimulation of select DBS targets using stentrodes seems feasible.
Neuralink Admits That Implant's Threads Have Retracted From First Patient's Brain, Possibly Due to Air in Skull futurism.com May 10, 2024, 11:46 a.m.
The company claims even with a reduced number of electrodes, it was able to actually increase the BPS, in the long run, thanks to adjustments made to the "recording algorithm" and improvements to "the techniques to translate these signals into cursor movements."

Musk's Neuralink says issue in brain implant fixed medicalxpress.com May 10, 2024, 11:42 a.m.
A company blog post on Wednesday said threads connecting the implant to Arbaugh's brain recently "retracted... resulting in a net decrease in the number of effective electrodes" and the patient's ability to operate the cursor. While offering no explanation for the receding threads, the company said it made modifications to make the implant more sensitive to neural signals. This, with other improvements, "produced a rapid and sustained improvement in bits-per-second, that has now superseded Noland's initial performance."
Neuralink Encounters Problem With First Brain Chip Implant www.itechpost.com May 10, 2024, 11:41 a.m.
In a blog post, the company shared that a number of connective threads have retracted. Neuralink did not give a specific number but it was enough to significantly affect the data speed and effectiveness of the chip. Despite the issue, the company assured that their team modified the recording algorithm to help improve the process between the signals. In addition, the increased sensitivity would enhance the user interface.

Neuralink didn't reveal how many specific threads have retracted from Arbaugh's brain tissue, but the company did explain a workaround was conceived. Modifications were made to the recording algorithm for the BCI, which led to improvements in Arbaugh's cursor movements. Most importantly, Neuralink considered removing the implant entirely but decided against it because it hasn't negatively impacted Arbaugh's health or safety.

What You Need To Know About Brain-Computer Interfaces www.forbes.com May 10, 2024, 11:36 a.m.
In my opinion, the least invasive technology will win out in the end. Similar to how the hybrid approach is winning with electric vehicles right now. People want the convenience and the flexibility. With brain and computer interfaces, the discreet strap or a hidden device will be most appealing. My prediction is that this will be very common in about 10 years to have this type of augmentation used as long as it isn't invasive. Meaning, it would be something worn outside the body rather than embedded inside. This will likely be possible as technology for detecting brain patterns continues to advance.
Paralysed Gamer Crushes 'Mario Kart' with Neuralink's Brain Chip www.ibtimes.co.uk May 10, 2024, 11:34 a.m.
Nolan Arbaugh, the first human with the Neuralink brain chip, claims he can consistently outmanoeuvre his friends in "Mario Kart" with mind control. This feat is awe-inspiring because he wins games most quadriplegics would struggle with. Early adopters of Neuralink's brain chip report using it for extended gaming sessions, with some logging up to 12 hours per day. The Elon Musk-led neurotechnology company unveiled results from the first 100 days of its groundbreaking PRIME Study.

Cortical Brain Stimulation with Endovascular Electrodes ieeexplore.ieee.org April 26, 2024, 6:10 a.m.
Electrical stimulation of neural tissue and recording of neural activity are the bases of emerging prostheses and treatments for spinal cord injury, stroke, sensory deficits, and drug-resistant neurological disorders. Safety and efficacy are key aspects for the clinical acceptance of therapeutic neural stimulators. The cortical vasculature has been shown to be a safe site for implantation of electrodes for chronically recording neural activity, requiring no craniotomy to access high-bandwidth, intracranial EEG.
Concept for intrathecal delivery of brain recording and stimulation device www.frontiersin.org April 26, 2024, 5:49 a.m.
The device described here was created with entirely off the shelf materials, but several alternative configurations exist. In general, the components are a long guidewire and expanding scaffold (here a stone retrieval basket was used); a guide catheter (here the sheath from the stone retrieval basket was used); electrodes attached to the scaffold and connected to the acquisition device (here platinum was used); and an acquisition component (here an Oscium mobile acquisition device was used). Any off the shelf existing devices could be used to make the device so long as the diameter of the scaffold and wire match the internal diameter of the guide catheter.

Also, the surface of neural devices can be chemically functionalized and coated with anti-inflammatory materials, which will show similar effects by minimizing foreign body responses. A surface modification technique can modify the surface of implants with a slippery surface inspired by the Nepenthes pitcher plant to achieve excellent repellency against bio-substances (Chae et al., 2020). Inspired by this, the surface of a fiber-based neural interface can be modified to achieve immune evasiveness and therefore reduce the decay of performance caused by immune responses.
Endovascular Neuromodulation: Safety Profile and Future Directions www.ncbi.nlm.nih.gov April 24, 2024, 4:04 a.m.
The intracranial venous system represents a promising conduit for neuromodulation devices. The ideal endovascular neuromodulation device would have low thrombogenicity, high biocompatibility without compromising durability, and carry a low infection risk. To achieve this goal, there are several areas in which further research is necessary.
