已建立安全可靠便攜易用

空間腦電測試平臺 

按計劃，空間站在軌腦電測試實驗將分為多個階段展開實施，目前已完成第一階段的目標任務，建立了安全可靠、便攜易用的空間腦電測試平臺，可供科學傢開展各類腦電研究實驗。

中國航天員科研訓練中心科技人員 王波：從神舟十一號開始，我們就開始了首次腦電實驗，通過腦控機器人驗證了腦機交互技術的在軌適用性。從空間站任務開始，我們陸續開展了數十次的在軌腦電測試，建成了一套平臺，發展了一些研究范式，實現了一些模型的檢驗，應該說達到了我們空間站建造期的預期的目標。

瞄準空間腦電測試研究的實際應用，研究團隊著力於數據建模和數據分析，目前已在腦力疲勞、腦力負荷、警覺度等數據模型建立方面取得多項成果。

多種創新手段提升空間腦電測試效率 

空間環境對腦功能有何影響？人腦在空間怎麼適應環境？在研究這些問題的基礎上，在空間站開展在軌腦電測試，還研究提升腦功能狀態的方法，為航天員長期駐留太空，維持良好的腦功能狀態、高效開展工作提供支撐。為了確保達到實驗目的，科研人員在實驗流程設計、采集硬件、分析算法上進行了大量的探索。

在中國航天員科研訓練中心，有一套空間人因測試地面模擬平臺，科研人員基於這一平臺開展地基相關測試。

中國航天員科研訓練中心科技人員 曹勇：這個實驗平臺它實際上是涉及多資源任務的一個平臺。它主要包括認知的一個思考記憶，包括我們的決策以及操縱等多種相關的資源，通過多任務的情況評估它綜合的復合的情況。在整個實驗的開始，航天員會被引導進入一個靜息的狀態，采集一段相對平穩的狀態的數據，作為我們後續任務數據的一個基線。在靜息完之後，航天員主要開展的操作就是根據我們這個任務的一個進程，操作操縱桿以及按鍵，對這個任務進行一個回應。此外我們會結合腦電采集的數據情況，綜合判斷航天員的腦力負荷的狀態。

針對空間站的環境約束，科研人員綜合比對不同測試方式的阻抗、信號質量和操作便捷性，改進了腦電電極形式，還對在軌實驗流程進行了優化設計。

航天員在軌腦電測試的數據下行之後，地面科研人員需要按照腦功能的不同狀態對數據進行對比分析。此外，科研人員還借助部分人工智能算法，創新了跨時間腦電特征分析方法，解決了小樣本腦功能狀態識別的難題。

空間腦電測試研究應用前景可期 

從遠期來看，在空間站開展在軌腦電測試研究，為的是探索宇宙對人腦演化的奧秘，揭示生命體演化過程中的重要機制，從而為開發類腦智能體提供新思路。那麼近期的應用目標又有哪些呢？

中國航天員科研訓練中心科技人員 王波：我們的研究目的其實有三個，一個是看空間環境對腦造成了什麼樣的影響。第二個也看一下人腦在空間怎麼適應環境，重塑自己的神經。第三個就是說我們要發展或者驗證一些腦能力提升的技術。

中國航天員科研訓練中心利用空間站科研平臺，與航天員共同開展的空間腦電測試研究，將期望在神經環路、認知基礎等方面取得突破。

中國航天員科研訓練中心科技人員 王波：通過在軌的一些技術去維持和提升人的腦部狀態，因為航天員在太空執行非常多復雜精細的作業，人腦保持一個良好狀態是一個關鍵，我們期望通過一些腦刺激等技術來提升人的這個能力，最大限度發揮人在太空中的作用。

腦機交互是目前科技前沿熱點，也有希望在空間環境得到重點應用。

中國航天員科研訓練中心科技人員 王波：這個有望在一些復雜的出艙，還有一些人機協同方面得到一些應用，最終還是提升這個系統的整體效率。

天津大學神經工程團隊是國內最先從事腦機接口領域研究的團隊之一，擁有領域內世界最大專利池，專利保有量居世界首位，大指令、快通訊、精辨識三項核心指標達國際最高水平，獲批首張“腦機人工神經系統”國傢醫療器械註冊證，佈局高性能無創腦機接口“器件-算法-系統-標準-應用”全鏈條國產化成果體系。

仰望星空，又腳踏實地。團隊以航天醫學領域的國傢重大工程項目需求為牽引，與中國航天員中心合作，十年磨一劍，設計開發五代中國空間站在軌腦機交互技術裝備，成功完成國際首次在軌腦機交互空間適應性測試並取得了良好的應用效果，中國載人航天的碩果首次得到《Science》專刊報道，‍為我國新一代航天醫學與人因保障系統提供了關鍵科學依據與技術支撐。

星辰大海的征途上

我們不會缺席！
