HSG Conferences

Date: 9-10 November
Location: Johns Hopkins University, Baltimore MD, USA

In the lead-up to SfN, the hippocampal head working group convened over two days to advance the development of the hippocampal head segmentation protocol. In addition to the official working group members Marshall Dalton and Renaud La Joie, the meeting welcomed the participation of HSG members Kim Nguyen, Ana Daugherty, Kelsey Canada, Carl Hodgetts, and Rosanna Olsen.

A special thanks to Arnold Bakker for hosting the meeting!

Date: 16-18 October, 2023

The MTL working group gathered in Lund to further their efforts in developing a unified MTL protocol. Additionally, a Marcus Wallenberg Symposium in the form of an online webinar was conducted to delve into the recent advancements made by the HSG working groups.

Date: 6-9 June, 2023
Location: University of Castilla-La Mancha, Albacete, Spain

This June, we held a HSG meeting in Albacete, Spain. The meeting consisted of a two-day neuroanatomy workshop, including a hands-on brain dissection session, and a two-day working group meeting continuing our efforts for both the hippocampal head and MTL cortex. More information about the event will be published shortly.

Organizers: Valerie Carr, Gustaf Rådman, Jenna Adams, Marshall Dalton, Laura Wisse, Ricardo Insausti, Mónica Muñoz López. Additionally, a special thanks to everyone else involved on part of the Human Neuroanatomy Laboratory at University of Castilla-La Mancha, Albacete!

Many thanks to Valerie Carr, Rosanna Olsen, and Manuella Yassa for organizing the meeting.

Date: November 11, 2017
Location: Washington, DC

Prior to the annual meeting of the Society for Neuroscience, we met to:

• Provide an update on harmonization efforts
• Encourage HSG members to participate in the first round of the questionnaire process
• Share research findings pertaining to hippocampal subfields

Many thanks to Arnold Bakker for organizing the meeting.

Date: July 14, 2017
Location: London, England

This was a smaller meeting of the Boundary Working Group to continue efforts to develop an initial protocol for segmenting the hippocampal head.

This meeting was made possible thanks to the financial support of the JPND 2016 call for “Working Groups for Harmonisation and Alignment in Brain Imaging Methods for Neurodegeneration” (see our project page here).

Many thanks to Martina Bocchetta for hosting the meeting.

Date: April 2-3, 2017
Location: Douglas Mental Health University Institute, Montreal

This was a smaller meeting of the Boundary Working Group, during which members:

• Provided an update on the harmonization effort for the hippocampal body
• Worked towards developing an initial protocol for segmenting the hippocampal head

This meeting was made possible thanks to the financial support of the JPND 2016 callfor “Working Groups for Harmonisation and Alignment in Brain Imaging Methods for Neurodegeneration” (see our project page here)

Thanks to Mallar Chakravarty for hosting the meeting

Date: November 11, 2016
Location: San Diego, CA

This was a two-part meeting, the first of which took place at UCSD and was a smaller meeting of the Boundary Working Group. The second day of the meeting was open to the broader HSG and any interested attendees of SfN.

Broadly, the aims of this meeting were to:

• Provide an update on the harmonization effort from the Boundary Working Group
• Engage the broader community about current and future directions
• Share research findings during an afternoon research symposium

See the program for a full list of presentations.

Thanks to all who attended this productive meeting! It was extremely encouraging to learn about the progress made by members of the Boundary Working Group (BWG). Specifically, the BWG provided updates regarding development of a protocol to define: the outer boundaries of the hippocampal body (anterior/posterior, medial/lateral, inferior/superior), the inner boundaries of the hippocampal body (subiculum, CA 1, 2, 3, and dentate gyrus), and preliminary efforts to define subfields within the hippocampal head. We also learned about efforts from the Questionnaire Working Group to put these protocols into writing, which will first be disseminated to the BWG and then to the broader subfield community for feedback. We had a productive group discussion regarding the progress of these groups, and also heard an exciting series of research talks in the afternoon.

Thanks to Christine Smith, Rosanna Olsen, and Valerie Carr for hosting the meeting.

Dates: October 15 - 16, 2015
Location: Northwestern University, Chicago

We would like to thank all the participants of this exciting and successful meeting. This intense two-day retreat was a major step forward: we succeeded at developing a first draft of an harmonized protocol for subfield segmentation of the hippocampal body.

The meeting started with presentations of the recent progress from multiple working groups.

- Outer boundary group (presentation by David Berron). How should we use and/or adapt existing harmonized protocols for hippocampal volumetry (see the EADC-ADNI Harmonized Protocol project website) to our specific high-resolution images? How should we handle white matter? CSF pools? How should we deal with the specific issues related to partial voluming? Where is the most medial boundary of the hippocampus/subiculum?

- Histology working group. Laura Wisse presented preliminary data on the behalf of the histology working group (J. Augustinack, R. Insausti, K. Amunts and O. Kedo), showing segmentation of hippocampal subfields on high-resolution histology slices from three expert groups. The goal of the group was to provide 'gold standard' histology segmentations of the hippocampal body from multiple individuals.

- Body ranging rules. Where is the hippocampal body? On which slice does it starts? Where does it end? Ana Daugherty presented preliminary data on the reliability of previously-determined landmarks. For that purpose, 9 volunteers had assessed the boundaries of the hippocampal body on high-resolution MR images nicely provided by several groups of the harmonization project.

Following these presentations, we constituted small working groups to discuss and make decisions about specific boundaries: i) CA1-Subiculum, ii) CA1-2-3 and, iii) CA3-DG. After multiple discussions, decisions were made regarding each of these boundaries.

Next steps will be necessary to carefully check these rules; for example to check them more thoroughly with histology and to discuss their generalization across individuals, ie. considering hippocampi with variable (flat, round) shapes. Then, we will initiate a small-scale reliability attempt with expert raters.
