"Vivani’s wholly owned subsidiary Cortigent, formed to continue the business of Second Sight, is developing targeted #neurostimulation systems intended to help patients recover critical body functions" https://finance.yahoo.com/news/vivani-medical-reports-second-quarter-214500374.html As expected soon leaving the visual prosthesis field? $CRGT $VANI #Orion #BCI #NeuroTech

Of potential interest: Can you trust your stimulation electrode - really? We found el. stimulation is a less straight forward procedure than some players in #neuromodulation #neurostimulation #bioelectronicmedicine seem to believe. Platinum is not "just" an inert transfer channel! Its "history" and surface states play a crucial roles - might even drive the stimulation outside the water window...
Platinum is a diva - treat it as such! DOI 10.1088/1741-2552/acdd9d

Subjective signal strength distinguishes reality from imagination
https://www.nature.com/articles/s41467-023-37322-1

"... imagined and perceived signals are in fact intermixed, with judgments of reality being determined by whether this intermixed signal is strong enough to cross a reality threshold. A consequence of this account is that when virtual or imagined signals are strong enough, they become subjectively indistinguishable from reality... "

"... While currently the most common driver of top-down signals is imagination, in near-future scenarios in which brain stimulation and/or virtual reality technology is used to drive sensory signals we might be less able to tell apart reality from unreality than we would like to believe. Our model provides a framework within which to investigate these issues, and offers a route towards ensuring our reality thresholds remain well-calibrated in the face of technological advances. .."

To verify this threshold hypothesis it would interesting to see if people with with psychosis have strong internal signals?

hello #brainstim folk. If you aim to stimulate #somatosensory cortex, please ignore the '2cm rule' for finding #S1-hand. This heuristic appears in the majority of #TMS papers. We know this heuristic is wrong (papers below), for example (red=M1-hand, blue=S1-hand) 1/6:

How can we manage and treat chronic pain?

Most pain medications have side effects. Neurostimulation could be the answer!

The #EUFunded project, CAPRI, has developed a new, invasive approach to #neurostimulation that treats pain earlier in the pathway👉 https://europa.eu/!4x64PN

In order to address this challenge, we release an #pensource phenomenologically realistic #cortical phosphene simulator and #machinelearning pipeline!! Our simulator has in account most of the common #neurostimulation parameters used by researchers, and biological constraints 5/

Improved working memory by non-invasive light stimulation of right prefrontal cortex, plausibly by modulating connectivity with superior intraparietal sulcus.

Selective for right side and at 1064 but not 852 nm.

Young adults, n=90 split across 4 studies.

heute habe ich an der ag #ethik der initiative #d21 teilgenommen. besonders spannend fand ich die diskussion über das thema #web30. außerdem haben wir uns mit #neurostimulation und der zukunft der #robotik befasst.
