Dopamine-driven synaptic credit assignment in neural networks
Saranraj Nambusubramaniyan, Shervin Safavi, Raja Guru +1
Solving the synaptic Credit Assignment Problem(CAP) is central to learning in both biological and artificial neural systems. Finding an optimal solution for synaptic CAP means sett…
A Minimal Quantitative Model of Perceptual Suppression and Breakthrough in Visual Rivalry
Christopher J. Whyte, Hugh R. Wilson, Shay Tobin +7
When conflicting images are presented to either eye, binocular fusion is disrupted. Rather than experiencing a blend of both percepts, often only one eye's image is experienced, wh…
TranCIT: Transient Causal Interaction Toolbox
Salar Nouri, Kaidi Shao, Shervin Safavi
Quantifying transient causal interactions from non-stationary neural signals is a fundamental challenge in neuroscience. Traditional methods are often inadequate for brief neural e…
Perceptual multistability: a window for a multi-facet understanding of psychiatric disorders
Shervin Safavi, Danaé Rolland, Philipp Sterzer +2
Perceptual multistability, observed across species and sensory modalities, offers valuable insights into numerous cognitive functions and dysfunctions. For instance, differences in…
