Happy to announce that the HSG protocol for segmentation of the hippocampal tail is now published in Hippocampus! 🎉
Developed together with the hippocampal imaging community, it complements the existing HSG body protocol for consistent segmentation of body and tail.

Unlike sight or hearing, which route through the thalamus, smell connects directly to the limbic system: the entorhinal cortex and hippocampus. When olfactory circuits degrade early in disease, these memory structures lose vital input and face accelerated disuse atrophy.

Dental health resulting in bleeding gums has been linked to Alzheimer's. It causes a bacteria to prenetrate the blood brain barrier and reach the hippocampus (memory). An inflammatory response leads to toxic enzymes that produce plaques found in the autopsies of 90% of Alzheimer's patients.

Andrea Hiott @lovephilosophy.substack.com has mastered "holding paradox" in neuroscience, pointing to the dual-natured history of the hippocampus as a prime case study.
We discuss her new book all about it (and much more).

KDS is correct. Night Shade released his complete works, restored as closely as possible to the original text, arranged by publication date. Hippocampus Press has been gathering the restored versions and publishing them by setting or theme—Averoigne, Zothique, etc. Same text, different arrangement.

The hippocampus of the chickadee grows in autumn that they may remember where the locations of the many seeds they stash for winter. I love watching them at the feeders this time of year as they load up on the goodies, darting in and darting out. Little cuties!
