COMMENT This elegant study provides proof-of-principle evidence that the cascading component of the “amyloid cascade hypothesis” can be unhinged. The study shows that a lot of amyloid plaque accumulation does not necessarily lead to tau pathology and ...
COMMENT This duet of papers represents the swan song of one of the deepest thinkers into the fundamental biology of neurodegeneration, our recently departed friend Sue Lindquist, who sadly died a few months ago. The papers illustrate the magnificent creativeness ...
COMMENT “Where, oh where, is Aβ?” Menno Witter is a leading expert on the anatomical organization of the hippocampal formation, i.e., the entorhinal cortex plus hippocampus proper. This latest manuscript, typical of the Witter lab in its elegance and rigor, ...
COMMENT This is a fascinating paper, with three main points of interest: First, it is notable that H.M. has a near-complete ablation of the entorhinal cortex, yet there is remarkable preservation of many hippocampal regions (i.e., the dentate gyrus, the CA ...
COMMENT This work very much concords with our PNAS paper, which found that exercise causes a selective increase in dentate gyrus CBV (Pereira et al., 2007). One thing to note is that they find that the increase in hippocampal volume correlates with exercise ...
COMMENT The ability to visualize disease has long motivated and driven the history of Western medicine. The end of the nineteenth century represents a turning point in the ability to do so: At around the same time neuroanatomists perfected staining techniques ...
COMMENT Although little more that a decade old, fMRI already has an established pantheon of "giants in the field." Seiji Ogawa, one of these giants, was the first to observe that when rodents breathe, 100 percent oxygen-diminished contrast is observed ...
COMMENT When introduced as a clinical tool in the 1980s, MRI transformed the field of clinical neuroscience. Visualizing the brain with exquisite anatomical resolution was one thing, but to accomplish this feat noninvasively, so that human subjects could be ...
