一篇新发表在 Science 的论文指出，在灵长类皮层组织中存在一个相反的分子梯度轴，为研究大脑结构提供了一个新的框架。
《科学》杂志 2026 年 3 月发表的一篇论文报道了丘脑在单突触水平对视觉皮层的激活，显示出对脑电路进行更精细测量的持续推进。
A new study in mice suggests psychedelic compounds make the brain prioritize stored memories over real sensory input — causing perception to be driven by internal models rather than present reality.
Researchers have found that Chlamydia pneumoniae, a widespread bacterium known for causing respiratory infections, can invade the brain and retina where it persists for years, triggering inflammation and amyloid-beta accumulation linked to Alzheimer's disease. The discovery opens new avenues for early detection through retinal imaging and potential antibiotic treatments.
Researchers from the University of Southern Denmark and Bern University Hospital found no evidence that the rat brain produces or stores DMT in serotonin-releasing neurons, undermining a decades-old hypothesis about the psychedelic compound's natural role in brain chemistry.
