15 p, 1.7 MB Flexible categorization in perceptual decision making / Prat-Ortega, Genís (Centre de Recerca Matemàtica) ; Wimmer, Klaus (Centre de Recerca Matemàtica) ; Roxin, Alex (Centre de Recerca Matemàtica) ; de la Rocha, Jaime (Institut d'Investigacions Biomèdiques August Pi i Sunyer)
Perceptual decisions rely on accumulating sensory evidence. This computation has been studied using either drift diffusion models or neurobiological network models exhibiting winner-take-all attractor dynamics. [...]

13 p, 1.9 MB Sensory integration dynamics in a hierarchical network explains choice probabilities in cortical area MT / Wimmer, Klaus (Institut d'Investigacions Biomèdiques August Pi i Sunyer) ; Compte, Albert (Institut d'Investigacions Biomèdiques August Pi i Sunyer) ; Roxin, Alex (Centre de Recerca Matemàtica) ; Peixoto, Diogo (Stanford University. Department of Neurobiology) ; Renart, Alfonso (Champalimaud Centre for the Unknown. Champalimaud Neuroscience Programme) ; de la Rocha, Jaime (Institut d'Investigacions Biomèdiques August Pi i Sunyer)
Neuronal variability in sensory cortex predicts perceptual decisions. This relationship, termed choice probability (CP), can arise from sensory variability biasing behaviour and from top-down signals reflecting behaviour. [...]

33 p, 2.5 MB UP-DOWN cortical dynamics reflect state transitions in a bistable network / Jercog, Daniel (Institut d'Investigacions Biomèdiques August Pi i Sunyer) ; Roxin, Alex (Centre de Recerca Matemàtica) ; Barthó, Peter (MTA TTK NAP B. Research Group of Sleep Oscillations) ; Luczak, Artur (University of Lethbridge. Canadian Center for Behavioural Neuroscience) ; Compte, Albert (Institut d'Investigacions Biomèdiques August Pi i Sunyer) ; de la Rocha, Jaime (Institut d'Investigacions Biomèdiques August Pi i Sunyer)
In the idling brain, neuronal circuits transition between periods of sustained firing (UP state) and quiescence (DOWN state), a pattern the mechanisms of which remain unclear. Here we analyzed spontaneous cortical population activity from anesthetized rats and found that UP and DOWN durations were highly variable and that population rates showed no significant decay during UP periods. [...]

108 p, 4.1 MB Attractor dynamics in perceptual decision making : from theoretical predictions to psychophysical experiments / Prat-Ortega, Genís ; de la Rocha, Jaime, dir. ; Roxin, Alex, dir. ; Alarcón Cor, Tomás, dir. ; Universitat Autònoma de Barcelona. Departament de Matemàtiques
De tant en tant, els humans i els animals en general hem de respondre a certs estímuls, que poden ser ambigus. Fa uns anys, abans que s'introduís el videoarbitratge (VAR; video assistant referee), els àrbitres de futbol no ho tenien fàcil. [...]
From time to time humans and animals must respond to a certain stimulus that can be ambiguous. In the old days, before the creation of video assistant referee, football referees had a very hard life. [...]
