How does circadian rhythm disruption affect memory?
HONOURS THESIS 2023 / SNODGRASS BEST HONOURS CONFERENCE PRESENTATION AWARD
Circadian rhythms are commonly associated with sleep cycles, but they really refer to any biological cycle that spans 24 hours. Disrupted circadian rhythms are a mismatch between a biological cycle and time of day, like being jet-lagged or regularly up at night. In our modern day society - filled with all-nighters, night-shifts, and frequent travel across time zones - most everyone can relate to circadian disruption. But how might this near-constant disruption affect memory? Incé Husain, a PhD student at Western University, completed her Honours thesis in Psychology last year with Dr. Scott Deibel on how disrupted circadian rhythms affect memory. Incé analyzed gene expression in the hippocampus (the region of the brain associated with memory) of rats who had normal circadian rhythms versus those with abnormal circadian rhythms. She found that after only seven days of circadian rhythm disruption, the rats whose circadian rhythms were disrupted had altered activity in genes associated with learning and memory.

“I realized I did not know much about this population”: How the transition out of high school impacts youth with autism or intellectual disabilities
HONOURS THESIS 2023
Autism is a developmental disorder characterized by difficulties in social behaviour and communication. Curious to learn about the experiences of youth with autism, Yara Bayoumi, a graduate from the Bachelor of Arts program in Psychology, did her honours thesis on how quality of life in youth with autism or intellectual disabilities changes during their transition out of high school. Results from this type of study may help schools develop better resources for supporting this youth. She shares how she surveyed caregivers of youth with autism, her process for dealing with her data, and how fulfilling she found the unpredictable aspects of research.

“It is a debilitating disease”: Finding biomarkers for the early detection of Alzheimer’s disease
EXTERNAL RESEARCHER / MUN
Characterized by extreme deficits in memory and thinking, Alzheimer’s disease is a debilitating brain condition that currently has no cure. Mark Russell, a recent chemistry graduate from Memorial University of Newfoundland, completed his honours thesis on whether carotid arteries - the arteries that carry oxygen to the brain - change in structure and function when Alzheimer’s disease is beginning. Using a mouse model, he did ultrasounds to study differences in carotid arteries in diseased versus non-diseased mice. These differences may be useful in detecting Alzheimer’s disease sooner, and therefore in getting treatments started as soon as possible. Aspiring to study veterinary medicine, he shares how he enjoyed working with mice and the ultrasound machine, and recommends that all students try research.

“The satisfaction that comes with a perfect little spherical gel bead”: Preparing ingestible forms of psilocybin and CBD to treat mental health disorders
EXTERNAL RESEARCHER / ACADIA
Emily Sabean is completing a Master’s in Chemistry at Acadia University. Her research is about creating a drug delivery vehicle (i.e. a way to package medications so they can be ingested) containing CBD and psilocybin for the treatment of mental health disorders, like depression and anxiety. She discusses how current antidepressants are not sufficient for helping everyone who is managing a mental health disorder, how no novel medications have entered the market in over twenty years, her research method for creating delivery vehicles for CBD and psilocybin, and the satisfaction she gets from a successful result.

Why do adolescents have low intentions to seek help from professionals?
HONOURS THESIS 2023
Sof Mehlitz completed Honours in Psychology with a Specialization in Neuroscience (BSc), and a biology minor. Inspired by past research, they attempted to identify factors that might underlie why adolescents have low intentions to seek help from professionals, and how often adolescents intend to seek help from teachers and mental health professionals. They found it most interesting that these factors were different depending on whether a mental health professional or a teacher was considered for help, suggesting that help-seeking intentions are professional-specific.

“Picking up a fragile object, like an egg, can turn into a monumental task”: Improving perceptions of grip strength in prosthetic users
EXTERNAL RESEARCHER / ACADIA
Lincoln Inglis completed his Bachelor of Science in Psychology and a minor in computer science from Acadia University. His thesis studied how to improve prosthetic users’ perceptions of grip strength. Specifically, he studied whether accompanying a prosthetic hand with visual stimuli that changes with grip strength can help prosthesis users perceive how strongly they are gripping objects. Involving app development and programming, Inglis shares that his computational neuroscience project allowed him to explore topics that traditionally lie outside psychology, and enjoyed the creative problem-solving that came with them.
