A Marcus Wallenberg Symposium

Date: October 16 2023

HSGPod suggestions

The HSG have a podcast that plan to cover various topics related to us as a group, our larger community, as well as the work that we do and how it is applied. We are eager to know more about the topics you would like to see covered on the podcast. Please give us suggestions below!

Inside the HSG: Covers updates on working group(s) activities and progress as well as information on the structure, goals, and vision of the HSG.

HSG Methods: Covers topical research spanning multiple areas of study involving the hippocampus and MTL cortices. Also delves into new methods and resources for researchers investigating these regions.

HSG Clinical: Covers clinical considerations and potential applications of the research conducted by those in the HSG community and beyond.

HSG Community: Covers updates on opportunities to connect with the HSG as well as tips about networking, conferencing, and all things academia.

Resources and recommendations

Protocols and Sample Data

We provide here a single subject’s MRI dataset at reasonably high resolution to provide a common dataset on which to compare different protocols for subfield segmentation. Labeled datasets were formatted using a common scheme and served as the basis for comparison and discussion at the HSG meetings.

Please see the documentation for information about the imaging data included in the evaluation dataset, segmentation formatting requirements, and deadlines. The full dataset can be downloaded from here. You will first be asked to sign in and register for an account.

Please email Paul Yushkevich with questions regarding the quantitative component.

Acquisition recommendations

Early in our efforts we established guidelines for the type of MRI scans that are the most useful for delineating hippocampal subfields. This included recommendations on the degree to which segmentation is reasonable given a set of image data. Here we also provided basic descriptions and links to detailed descriptions of both manual and automatic segmentation protocols along with examples of lab work typifying each approach. These resources can be found on on their separate working group page here.

Publications and White Papers

At the August 2014 HSG meeting in Irvine CA, we put forward a vision for developing a harmonized segmentation protocol. The document below outlines the steps towards harmonization. Here is the white paper. It was followed by several collaborative publications listed below.
