本研究通过测量中脑顶盖板（tectal plate）长度和面积，评估其在多种进行性核上性麻痹（PSP）临床变异型（如PSP-RS、PSP-P、PSP-SL等）中的诊断价值。结果表明，顶盖板长度能有效区分PSP变异型与健康对照及帕金森病（PD），且与疾病严重程度相关，为PSP的临床诊断提供了新型影像学生物标志物。

The study suggests that external cues, including morphogens and synaptic environment, influence the differentiation and specialization of tectal neurons beyond their genetic identity.

Kevin Eaise was once a pediatric patient at Children's Hospital of Philadelphia with a brain tumor, but he's now working alongside the doctor who performed his surgery years earlier.

The Tectal Race will set buyers back $210. Upgrades over the standard Tectal include a google retention strap on the rear of the helmet, a full aramid liner and the inclusion of a RECCO reflector.
