Celebrating MiNDS: Summer Successes
Author: Tegan Hargreaves

Sandhya successfully defended her PhD dissertation and has now begun Research and Clinical Training at McMaster. Congrats, Dr. Narikuzhy!

At the beginning of this summer, in May 2025, I had an incredible opportunity to attend the annual worldwide Vision Sciences Society (VSS) conference held in St. Pete Beach, Florida, United States. This five-day event brought together researchers, students, and professionals from around the world to share groundbreaking work in vision science. I was honored to present my thesis project titled “Position Specific Perceptual Learning”.
I explored whether improvements in perceptual tasks arise from finely tuned low-level visual neurons or from higher-level cortical processing. Using a texture identification task, I examined how learning transfers across different stimuli and spatial locations—research that deepens our understanding of how the brain adapts and refines visual perception, with promising applications to fields like radiology. We found that accuracy significantly dropped when the stimuli were altered, with a large additive effect when both texture and position changed, suggesting that learning was highly stimulus-specific.
Presenting this work at VSS was both an exciting and humbling experience and it sparked valuable conversations that will help shape the next stages of my research. I was fortunate to attend the conference with my wonderful lab co-workers—one a current master’s candidate and the other a PhD candidate. Sharing the experience with them made the week even more memorable, as we supported each other’s presentations, exchanged ideas, and connected with others in the vision science community.

First, she had a paper published in eNeuro titled “Calcium Dynamics in Hypothalamic Paraventricular Oxytocin Neurons and Astrocytes Associated with Social and Stress Stimuli”. Check it out here!

Finally, Katy organized a biweekly Neuro Writing Group for the summer – which will be running again this fall! Here, students set small, achievable goals that could be met within 45-minute chunks. It was hugely helpful in staying connected and getting things done over the summer season.
Continue to celebrate your fantastic achievements and wins from the summer. Here’s to many more successes in the fall term!
