 Hola a todo el mundo

La organización del ciclo de Seminarios Científicos En Neurociencia (SPIN) os recuerda que este próximo miércoles día 29 de Enero a las 12:00 en el centro de instrumentación de la UGR tendrá lugar el seminario inaugural de dicho ciclo de conferencias que será impartido por la Dra. Serena di Santo del Departamento de Electromagnetismo y Física de la Materia de la UGR. Os animamos a que asistais a este interesante seminario en neurociencia y cuyos detalles son:

Ponente: Dr. Serena di Santo

Titulo: Contextual modulation: towards bridging perception and the formation of neural representations

Abstract: Sensory systems rely on contextual cues to interpret sensory input, filling in gaps and resolving ambiguities to construct a coherent perception. Optical illusions exemplify this process, highlighting how the brain interprets visual information based on surrounding elements and prior experiences. Accordingly, in the visual cortex, context profoundly shapes neural responses to sensory stimuli, yet the circuit mechanisms underlying these effects across diverse stimulus conditions remain poorly understood.

I will introduce some key aspects of the anatomy and physiology of the visual cortex, outline the three most studied forms of contextual modulation, and present a data-driven unified circuit model. This model is designed to be analytically tractable (read: simple enough), while incorporating biologically realistic features, such as length scales and inhibitory cell types, and successfully capturing all three phenomena. First I will highlight a previously unrecognized feature of the neural representation of visual stimuli and discuss its perceptual correlates. Then, I will show how bottom-up, top-down, and recurrent inputs are integrated across retinotopic space to produce contextual effects.

By establishing causal links between neural responses, input geometry, and connectivity patterns, the model reveals how a single canonical cortical circuit differently modulates sensory responses depending on context. Additionally, it generates multiple testable predictions, offering broader insights into the principles governing neural circuit function.
