個人簡介:

楊國春,研究員,認知神經(jīng)表征與調(diào)控研究組組長。2012年于武漢大學(xué)獲得醫(yī)學(xué)學(xué)士學(xué)位(醫(yī)學(xué)檢驗專業(yè))。2018年于中國科學(xué)院大學(xué)獲得理學(xué)博士學(xué)位(認知神經(jīng)科學(xué)專業(yè))。2018年7月至2025年2月,先后在中國科學(xué)院心理研究所和美國愛荷華大學(xué)心理與腦科學(xué)系從事博士后研究。其研究成果發(fā)表于PLOS Biology, eLife, Journal of Neuroscience, Neuroscience & Biobehavioral Review等期刊。

 

認知神經(jīng)表征與調(diào)控研究組(Laboratory of Cognitive Neural Representation and Regulation):

        復(fù)雜的高級認知功能(如執(zhí)行控制、注意、記憶等)是人類區(qū)別于其他生物的核心特征。例如,人類可以借助豐富的想象和嚴密的邏輯思維,對未來進行復(fù)雜的計劃,這是其他生物難以企及的。理解高級認知功能的機制,不僅有助于揭示人類智慧的奧秘,也將為類腦人工智能的發(fā)展提供重要啟示。

        本研究組綜合運用認知行為范式、腦電(EEG)、功能磁共振(fMRI)和計算建模等技術(shù),深入探索高級認知功能的神經(jīng)表征機制及認知策略調(diào)控機制。

主要研究方向和研究問題:

(1)高級認知功能的表征機制:高級認知功能(如認知控制)在不同情境下具有不同的狀態(tài)。這些狀態(tài)如何在大腦中被記憶和表征?這些表征又如何指導(dǎo)行為?

(2)認知策略的調(diào)控機制:人類對外界信息的加工不是被動的,而是會基于目標要求和主觀意圖進行主動調(diào)控,從而強化重要信息、抑制無關(guān)干擾信息。這一調(diào)控過程如何實現(xiàn)?其背后遵循哪些原則?

(3)行為/神經(jīng)表征的類腦計算模型:根據(jù)外界輸入,大腦產(chǎn)生特定的活動,最終決定了行為表現(xiàn)。三者之間有怎樣的映射關(guān)系?能否通過計算模型實現(xiàn)統(tǒng)一描述?

(4)執(zhí)行功能的發(fā)展變化與相關(guān)疾?。?/strong>執(zhí)行功能是實現(xiàn)目標導(dǎo)向行為的基礎(chǔ),但是在特定人群中會表現(xiàn)出不成熟、退化或受損。執(zhí)行功能對應(yīng)的腦機制在畢生發(fā)展過程中會發(fā)生怎樣的變化?如何設(shè)計有效的研究范式來測量疾病人群中的執(zhí)行功能異常?
