Fourth-year Neuroscience PhD student Tedy Markova recently returned form a six-month internship at Biogen. There, she worked with previously collected clinical trial data to examine how the pathological protein tau accumulated in the brain in individuals with Alzheimer's Disease. The goal is to use this information to create more nuanced methods to examine clinical trial results-allowing for a more rigourous assessment of drug efficacy and helping to design beneficial treatments for more patients!

The locus coeruleus (LC) produces catecholamines norepinephrine and dopamine. Our group has investigated the extent to which the PET tracer [18 F]Fluoro-m-tyrosine (FMT) can be used to assess the neurochemical health of the LC-catecholamine system. In her talk, Hsiang-Yu reviewed the research our group has done in cognitively unimpaired older adults, which demonstrates interactive effects between LC-catecholamine synthesis capacity and Alzheimer’s disease-related biomarkers on cognitive function. Specifically, we find that higher LC-catecholamine synthesis capacity is associated with lower temporal lobe tau cross-sectionally and longitudinally, and better-than-expected memory performance given one’s tau burden. Higher LC-catecholamine synthesis capacity is also associated with a reduced risk of dementia as indexed by lower trait neuroticism and fewer depressive symptoms. She also discussed our ongoing efforts to evaluate [ 18 F]FMT PET’s correspondence with LC MRI structural imaging measures and the limitations of the [18 F]FMT tracer. Despite limitations, our findings to date are promising and suggest that [ 18 F]FMT imaging of the LC can shed light on neurobiological mechanisms underlying individual differences in cognitive aging trajectories and vulnerability to Alzheimer’s disease.

More than 100 of our participants and their friends/family members joined us to celebrate 5 years of BABS! We all gathered on the Brandeis campus for food and drinks and great conversation. Dr. Berry gave a talk on cognition, memory, super-agers, current findings from our studies, and future research opportunities. We had an incredible amount of interest in our different active studies! Thank you to those who signed up for studies at the event! A video of Dr. Berry's talk is available - just click play on the picture!July 31, 2024
Teodora Markova's prested a poster on relationships between tau pathology and depressive symptoms across two independent datasets, with a particular focus on tau in the amygdala. Some evidence was identified for unique contributions of amygdala tau to depressive symptoms in a cognitively normal population, but stronger evidence for interactions between tau and the APOE E4 genotype on neuropsychiatric trajectories.
Dr Jennifer Crawford gave a presentation on the contribution of brain structure and tau pathology on memory ability and metamemory (i.e., how one thinks and feels about their memory). Among findings from this research was evidence that brain structure (i.e.,volume of the hippocampus) was related to memory ability, whereas tau pathology in the hippocampus was related to metamemory, suggesting that memory ability and metamemory are distinct processes supported by different neural mechanisms.

Jourdan Parent recently published a manuscript in Biological Psychology entitled "Pathological and neurochemical correlates of locus coeruleus functional network activity.” This paper reports evidence that increased signaling between brain regions that communicate with the locus coeruleus, a region vulnerable to early Alzheimer’s, are linked to a higher presence of Alzheimer’s disease-related pathologies. However, higher locus coeruleus neurotransmitter function may diminish these effects. Her findings support research focused on understanding how Alzheimer's-related tau pathology spreads throughout the brain.

Fourth year PhD Student Claire Ciampa was awarded an NIH NRSA F31 fellowship. The grant supports her research investigating dopaminergic mechanisms of reward memory in healthy aging. The project involves joint PET/fMRI scanning on and off the dopamine-enhancing drug methylphenidate. Current findings show that participants have better memory while on methylphenidate, and also have better memory if incentivized with a monetary reward. Future directions include testing whether dopamine function (measured using [11C]raclopride PET scans) supports memory performance, and analyzing whether fMRI pattern similarity measures are associated with dopamine and memory.June 10, 2024
The Brandeis Neuroscience PhD program awarded 4th year PhD student Claire Ciampa the Best First Talk award in Spring 2024 for her presentation on preliminary behavioral and neuroimaging results based on our Aging, Dopamine, and Decision Making (ADDM) study. Claire’s results demonstrated memory-enhancing effects of both a dopaminergic drug (methylphenidate) and monetary reward. She also found that hippocampal activation, which is measured with fMRI, supports better object-context associative memory, which is in line with previous work. This year, her talk will expand on these analyses by incorporating dopamine PET measures (using the PET tracer [11C]raclopride]) and fMRI pattern analyses to further investigate how an individual's dopamine function impacts reward memory and neural patterns of activity.

Jourdan Parent graduated with her PhD from the Psychology program after 5 years of working in the Neurochemistry & cognition Lab. She was extremely involved in the ADDM study, and has successfully authored and co-authored several papers on work in our lab, which can be found in our publications page. She is now a Post-Doctoral Fellow at Massachusetts General Hospital investigating network dynamics that underly cognitive symptoms of long-COVID and Chronic Fatigue Syndrome using multimodal neuroimaging. We celebrated her achievements with a cruise on the Boston Harbor. We'll miss you, Jourdan!April 29, 2024
This $450,000 grant will support research using behavioral, psychophysiological, neuroimaging, and naturalistic approaches to understand daily life activity and its connection to Alzheimer’s disease. Doing cognitively effortful activities has been associated with maintaining cognitive function and a decreased risk of developing Alzheimer’s disease pathology. It is critical to understand the relationship between motivation to do these activities and changes to neuromodulatory systems. .

The National Institutes of Health awarded Dr. Berry $437,000 to study the "Dopaminergic mechanisms of resilience to Alzheimer's disease neuropathology."
Brain structure and function can be maintained despite the development of neuropathology. Certain neural mechanisms have been identified as potential targets for clinical intervention. Dopamine D2 receptor function has been linked to cortical thickness, executive function, and memory, and could act as a moderator of Alzheimer's Disease related tau and beta-amyloid pathology. This study will investigate the extent to which “optimal” D2 genotypes confer resilience to Alzheimer’s disease pathology.
