A satellite language network in the brain | MIT News | Massachusetts Institute of Technology
MIT’s McGovern Institute for Brain Research, led by Evelina Fedorenko, has identified four regions in the cerebellum involved in language processing, extending the known language network beyond the neocortex. Using functional MRI data from over 800 participants, graduate student Colton Casto analyzed cerebellar activity during language and non-linguistic tasks...

Fragile X study uncovers brain wave biomarker bridging humans and mice | MIT News | Massachusetts Institute of Technology
MIT researchers led by postdoc Sara Kornfeld-Sylla and Picower Professor Mark Bear identified a shared low-frequency brainwave biomarker in fragile X syndrome across humans and mice. Using EEG data from human boys and men, and surface visual cortex recordings in male mice, the team analyzed periodic power fluctuations in brain waves, avoiding traditional freque...

Study: AI chatbots provide less-accurate information to vulnerable users | MIT News | Massachusetts Institute of Technology
研究发现，尽管大型语言模型（LLMs）被宣传为可提升全球信息可及性的工具，但MIT中心对构造性传播（CCC）的研究显示，这些模型在面对英语水平较低、教育程度较低或非美国籍用户时，常出现准确率下降、拒绝回答、使用轻蔑或讽刺语言等问题。研究测试了GPT-4、Claude 3 Opus和Llama 3三个模型，使用TruthfulQA和SciQ数据集，结合用户背景信息（教育水平、英语熟练度、国籍）进行分析。结果显示...

3D-printing platform rapidly produces complex electric machines | MIT News | Massachusetts Institute of Technology
MIT researchers have developed a multimaterial 3D-printing platform capable of fabricating complex electronic devices, such as electric linear motors, in a single step using five functional materials. The system employs four extruders to handle different material forms—conductive inks, magnetic materials, and dielectric substances—enabling precise layer-by-la...
