大型腦部模型
Hemispheric 推出Descartes Foundation Model
Hemispheric 推出 Descartes，一款擁有 60 億參數的 AI 基礎模型，訓練數據涵蓋超過 25 萬小時的腦部活動記錄，這家 NeuroAI 公司同時公開亮相，並完成 5,200 萬美元的早期融資。此模型歷經六年開發，設計旨在解碼非侵入性腦部信號，並將其轉化為可實際應用的臨床及研究洞見。
此系統配合一款輕巧的乾式腦電圖頭戴裝置運作，於病人與應用程式互動約 15 分鐘期間，記錄腦部活動。Descartes 其後生成客觀結果，旨在支援診斷、治療方案選擇，以及中樞神經系統藥物及器械研究。初期應用將聚焦於創傷後壓力症候群、抑鬱症、阿茲海默症、思覺失調、焦慮症及輕度創傷性腦損傷等病症。
對臨床醫生及研究人員而言，此平台有望令腦部檢測變得更為客觀、更具個人化。Hemispheric 將運用此輪融資，擴大合作夥伴關係、壯大其腦部數據網絡、擴充美國團隊規模，並爭取監管審批。
英文原文
Hemispheric introduced Descartes, a six-billion-parameter AI foundation model trained on more than 250,000 hours of brain activity, as the NeuroAI company emerged from stealth with $52 million in early-stage funding. Developed over six years, the model is designed to decode non-invasive brain signals and translate them into actionable clinical and research insights.
The system works with a lightweight dry EEG headset that records brain activity while a patient interacts with an app for approximately 15 minutes. Descartes then generates objective results intended to support diagnosis, treatment selection and central nervous system drug and device research. Initial applications will focus on conditions including PTSD, depression, Alzheimer’s disease, schizophrenia, anxiety and mild traumatic brain injury.
For clinicians and researchers, the platform could make brain testing more objective and personalized. Hemispheric will use the funding to expand partnerships, grow its brain data network, scale its U.S. team and pursue regulatory approval.
