The best combo for a stellar symposium! I wish I could be there!πŸ₯²πŸ§ 
Interested in speech neuroprostheses? Come to the #SfN24 minisymposium organized by @HerffC and I. We have a fantastic lineup chosen to survey the many directions this field can go in: different recording modalities, languages, and behaviors (e.g. attempted vs. imagined speech).

Out today in @NatureMedicine, groundbreaking work by Philip Starr MD, PhD, Simon Little MD, PhD (@littleneuro) and colleagues shows that adaptive DBS provides better symptom control than standard DBS in a real-world setting: nature.com/articles/s41591-0…

Absolutely! sEEG is great for localizing the seizure onset zone. However, ECoG offers broader spatial coverage, which is crucial for mapping in complex cases where the identification of eloquent areas has higher relevance. This ensures better surgical planning and patient safety.
While sEEG has rapidly become our β€œgo to” option for localization, grids still have a role - particularly in mapping. This is a pt with a left frontal dysplasia radiographically abutting Broca. While you can map with sEEG, imho grids give you greater spatial coverage.

20 years ago today, an extraordinary 24-year-old, unable to move his hands due to cervical spinal cord injury, volunteered to have a tiny sensor placed into his brain so that he could control a computer cursor, his room lights, and a robot arm just by thinking about it.

96% of published findings in psychology are statistically significant. There are 2 options. 1) We study effects with more than 90% power, and more than 90% probability of being true. 2) There is MASSIVE publication bias. Hint: the answer is 2 journals.sagepub.com/doi/10.…

Intriguing paper in this week's Science: a new, much cheaper approach for MRI scanning It's an MRI scanner that uses a 0.05 Tesla magnet (vs. the current 1.5 - 3 T) and operates at a fraction of the cost (~$22,000 for the hardware), time (<10 minutes), and noise of a current MRI scanner Unlike current MRIs, the prototype scanner plugs into a standard wall socket, and doesn't need specialist shielding equipment It uses a deep learning (AI) strategy to improve the low signal-noise ratio that's inherent to lower field strength MRIs Although the images from the 0.05 T approach aren't as good as from 3 T MRI, they don't seem to be far off Zhao et al: science.org/doi/10.1126/scie…

I’m looking for a postdoc researcher to work with me, on the cortical plasticity of blinds, with fMRI (3T, 7T, and potentially 11.7T). See details in the picture. Please spread the word to people interested πŸ™

Brain-To-Text Competition 2024 This is the most fascinating BCI competition yet, organized by Stanford. Everyone has time to develop the world's best brain-to-speech decoder! Deadline: June 2, 2024 Task: Predict attempted speech from brain activity. Dataset: They've recorded 12,100 sentences from a patient who can no longer speak intelligibly due to amyotrophic lateral sclerosis (ALS). """For each sentence, we provide the transcript of what the participant was attempting to say, along with the corresponding time series of neural spiking activity recorded from 256 microelectrodes in speech-related areas of cortex""" Link: eval.ai/web/challenges/chall… Just letting you know we're jumping into this challenge! @alex_timcenko and @koval_alvi, together with @alvilabs team, we're going to create something interesting. Like this post if you want to follow our updates❀️

New paper: managing-ai-risks.com Companies are planning to train models with 100x more computation than today’s state of the art, within 18 months. No one knows how powerful they will be. And there’s essentially no regulation on what they’ll be able to do with these models.
