Paria Mehrani presents “Learning a model of shape selectivity in V4 cells reveals shape encoding mechanisms in the brain” at Neuroscience 2021

By tech | November 10, 2021 | Category Presentations

Venues: Neurosciences 2021, Virtual Paper:Learning a model of shape selectivity in V4 cells reveals shape encoding mechanisms in the brain Abstract: The mechanisms of local shape information transformation from V1 to more abstract representations in IT are unknown. Studying the selectivities in intermediate stages of transformation suggest plausible mechanisms. For example, findings in Macaque V4 […]

Venue: CVR 2021, Virtual Paper: Learning a model of shape selectivity in V4 cells reveals shape encoding mechanisms in the brain Abstract: The mechanisms involved in transforming early visual signals to curvature representations in V4 are unknown. We propose a hierarchical model that reveals V1/V2 encodings that are essential components for this transformation to the […]

Media Mention: Professor John Tsotsos disproves 60-year-old Perception Theory

By tech | November 6, 2019 | Category Uncategorized

Vision researchers at York University have disproved a long-standing theory of how the human vision system processes images, using computational models and human experiments. A team led by John Tsotsos, professor in the Department of Electrical Engineering and Computer Science at the Lassonde School of Engineering, found that the human brain does not select interesting portions […]

Paria Mehrani presents “Multiplicative modulations enhance unique hue representation in V4” at Neuroscience 2019

By tech | October 25, 2019 | Category Presentations

Venue: Neuroscience 2019, Chicago, IL Paper: Multiplicative modulations enhance unique hue representation in V4 Abstract: Which region in the brain represents unique hues is unknown. We introduce a hierarchical model inspired by neural mechanisms in the visual system for local hue representation and with computational simulations suggest that cells in V4 have the capacity to […]

Paria Mehrani presents “Early Recurrence Enables Figure Border Ownership” at the Society for Neuroscience Meeting 2019

By tech | October 25, 2019 | Category Presentations

Venue: Neuroscience 2019, Chicago, IL Paper:Early Recurrence Enables Figure Border Ownership Abstract: Rubin’s face-vase illusion demonstrates how one can switch between two different interpretations depending on how the figure outlines are assigned [1]. This border ownership assignment is an important step in the perception of forms. Zhou et al. [2] found neurons in the visual […]

Lassonde Undergraduate Research Awards 2019

By tech | September 19, 2019 | Category Uncategorized

Since 2015 Lassonde has offered internal summer research awards to provide research experience for undergraduate students. The LURA program is run jointly with NSERC USRA and ends each summer with a professional conference that includes poster sessions, oral presentations, networking and awards. This year Dr. John Tsotsos supervised undergraduate researcher Brittany Danishevsky. She presented her […]

Paria Mehrani presents “Multiplicative modulations enhance unique hue representation” at CVR 2019

By tech | July 29, 2019 | Category Presentations

Venue: CVR 2019, York University Paper: Multiplicative modulations enhance unique hue representation Abstract: There is still much to understand about the color processing mechanisms in the brain and the transformation from cone-opponent representations to perceptual hues. Moreover, it is unclear which areas(s) in the brain represent unique hues. We propose a hierarchical model inspired by […]
