Maureen and Rose will be in San Diego Nov 3-7 for the Society for Neuroscience meeting.
Rose will be presenting her poster on Sunday afternoon, HHH14: Brain networks supporting the composition and precision of episodic memory.
Hope to see you there!
We are pleased to welcome Helen Schmidt as our new lab manager. Helen recently completed her Masters at University College London, where she used MEG to study neural processing related to reward and punishment.
Unfortunately, this also means that we must say farewell to our inaugural lab manager, Max Bluestone. Max will be moving on to a Masters program in Health Data Science at Dartmouth. We could not have asked for a better first lab manager, and we wish Max the best!
To celebrate fond farewells and new beginnings, we did our first escape room as a lab– making it out with a cool 40 seconds to spare.
This position has now been filled.
The Memory Modulation Lab at Boston College is hiring a full-time Research Assistant/ Lab Manager for an anticipated start date in summer 2018. Our lab investigates the neural bases of episodic memory and emotion in healthy young adults. We use a combination of behavioral methods, functional magnetic resonance imaging (fMRI), and electroencephalography (EEG). For more information about the lab, please see: http://www.thememolab.org.
Duties include: recruiting and scheduling participants, maintaining lab IRB documents, preparing stimuli and experimental presentation scripts, collecting and analyzing behavioral and/or imaging data, and managing a team of undergraduate research assistants.
The successful applicant will have strong interpersonal and organizational skills, interest in cognitive neuroscience research, and experience or interest in learning one or more programming languages (e.g., Matlab, R, Python). Prior research experience is required, as is a Bachelor’s degree in psychology, neuroscience, computer science, mathematics/ statistics, or a related field. A two-year commitment is required.
To apply, please send a cover letter and CV detailing your research experience and qualifications to Dr. Maureen Ritchey, firstname.lastname@example.org. Boston College conducts background checks as part of the hiring process. Boston College is an Affirmative Action/Equal Opportunity Employer and does not discriminate on the basis of any legally protected category including disability and protected veteran status.

The MemoLab will be in DC Nov 11-15 for the Society for Neuroscience meeting.
- Monday afternoon, poster VV23 - Effects of contextual reinstatement on retrieval of item-emotion associations (Rosie) - POSTER
- Wednesday afternoon, poster UU18 - The neural dynamics of retrieving context-dependent emotional associations (Max) - POSTER
- Wednesday afternoon, poster UU11 - Retrieval-related memory enhancement and reactivation in the posterior medial/core recollection network (MR as co-author)
Hope to see you there!
There’s something about the fall– the crisp air, the anticipation of a new year– that makes me feel like I can do anything. This year, we tried to channel that energy into our first lab retreat. Together we hiked a mountain, toasted marshmallows, and contemplated the future of the MemoLab and, more generally, of cognitive neuroscience.

Contributions: M.R. chaired the program committee; R.S. chaired the food committee; R.C. chaired the hiking committee; M.B. chaired the fire committee; and K.K. chaired the guacamole committee.
We are delighted to welcome Dr. Rose Cooper to the Memory Modulation Lab. Rose completed her PhD at the University of Cambridge, where she studied the cognitive neuroscience of episodic memory in autism spectrum disorder. Her postdoc research will build on her expertise in memory precision and brain networks. We’re excited to begin this new collaboration!
We recently celebrated the end of our first semester by hosting a lab-warming party– hot cocoa, cider, and all. Many thanks to the rest of the BC Psychology department for such a warm welcome.
Stressful experiences can have a powerful influence on what we learn and remember. Prior work has shown that stress after learning can influence later memory, but until now, we knew very little about how the retroactive effects of stress interact with processes that were active during learning. In this study, we showed that the effects of post-encoding stress on memory depended on the level of hippocampal and amygdala activity during encoding. This means that, when stress followed encoding, it preferentially protected memories for information that had elicited a lot of activity in these important memory structures. In this way, stress was acting as a mnemonic filter, selectively keeping the memories that were “tagged” at encoding, compared to those that were not.
For more information, check out the paper linked below, as well as its companion behavioral paper.

The lab officially opened its doors on July 1st. I’m happy to report that lab renovations are done, IRBs are submitted, and R00 funding is pending final approval. Hiring felt a bit like assembling the dream team, and I’m looking forward to my lab members’ arrivals later this summer.
We are currently focused on starting strong, but we’re also looking to the future. If you’d like to join us, or know someone who would, we will be recruiting a graduate student and postdoc for start dates next summer/ fall 2017.
Now available online! This paper extends some of our prior work (Ritchey et al., 2014, JoCN) by using resting-state functional connectivity to parcellate the medial temporal lobes along the longitudinal axis. We found that a data-driven parcellation scheme split the parahippocampal gyrus into 3 clusters: one corresponding to the parahippocampal cortex, and two corresponding to anterior and posterior portions of the perirhinal cortex. These clusters had distinct patterns of connectivity with the rest of the brain, and importantly, these areas played different roles in associative memory encoding.
So what does this mean? First, the parahippocampal gyrus is not a homogeneous structure, but rather it comprises at least 3 areas with different connections. Second, the different connections seem to be related to differences in memory-related function– differences that we did not observe until we applied our parcellation algorithm. This speaks to the utility of connectivity measures for mapping out the functional organization of medial temporal lobe cortex.
Also - huge congrats to first author Shao-Fang (Pam) Wang! She completed this work as a research assistant at UC Davis, and this is her first first-authored publication.
Welcome to the official website of the Memory Modulation Lab! Our lab opens its physical doors at Boston College in July, but today marks the opening of our own little chunk of virtual space.
Building this website has been a hobby of mine for the past few months, and I hope you like the results. The website is powered by Jekyll and hosted by GitHub (more info here), so it should be super easy to maintain and update. Can’t find something you’re looking for? Let me know.
I traveled to Boston College this past week to meet with the lab renovation team. Our new space is going to have quiet office space for grad students and postdocs, two testing rooms, an area for group meetings, and- of course- an accent wall (color TBD, but you can take a guess).
