研究方向

李晟研究員主要從事的研究包括視覺分類與知覺決策的神經機制，知覺決策與高層認知功能的互動，以及功能性腦成像的數據分析方法與建模。主要研究手段包括將功能性磁共振成像(fMRI)，腦電(EEG)，與心理物理相結合的方式，並輔以機器學習等多種計算方法。李晟研究員在國際學術刊物上發表論文多篇，包括Neuron，Journal of Neuroscience，IEEE Transactions on Neural Networks等權威性雜誌。

研究興趣：

1. 視覺分類與知覺決策的神經機制。

2. 功能性腦成像的方法與建模，多模態功能性腦成像（fMRI, EEG, MEG）技術。

3. 視覺神經編碼機制。
