A saliency-based bottom-up visual attention model for dynamic scenes analysis
Ramirez-Moreno DF, Schwartz O & Ramirez-Villegas JF. Biological Cybernetics. 2013 107(2): 141-160
Research & Publications
The Ramirez Lab investigates the system-level neural mechanisms underlying memory formation and maintenance. Our work bridges brainstem, thalamic, hippocampal, and cortical circuits — combining in vivo electrophysiology, optogenetics, computational modelling, and mesoscopic imaging in rodents and humans.
