Cortical state transitions and stimulus response evolve along stiff and sloppy parameter dimensions, respectively

Ponce-Alvarez, Adrián; Mochol, Gabriela; Hermoso Mendizábal, Ainhoa; De la Rocha, Jaime; Deco, Gustavo (eLife, 2020)

Previous research showed that spontaneous neuronal activity presents sloppiness: the collective behavior is strongly determined by a small number of parameter combinations, defined as ‘stiff’ dimensions, while it is ...
Proactive and reactive accumulation-to-bound processes compete during perceptual decisions

Hernández-Navarro, Lluís; Hermoso Mendizábal, Ainhoa; Duque, Daniel; De la Rocha, Jaime; Hyafil, Alexandre (Nature Research, 2021)

Standard models of perceptual decision-making postulate that a response is triggered in reaction to stimulus presentation when the accumulated stimulus evidence reaches a decision threshold. This framework excludes however ...
Response outcomes gate the impact of expectations on perceptual decisions

Hermoso Mendizábal, Ainhoa; Hyafil, Alexandre; Rueda Orozco, Pavel Ernesto; Jaramillo, Santiago; Robbe, David; De la Rocha, Jaime (Nature Research, 2020)

Perceptual decisions are based on sensory information but can also be influenced by expectations built from recent experiences. Can the impact of expectations be flexibly modulated based on the outcome of previous decisions? ...
Stochastic transitions into silence cause noise correlations in cortical circuits

Mochol, Gabriela; Hermoso Mendizábal, Ainhoa; Sakata, Shuzo; Harris, Kenneth D.; De la Rocha, Jaime (National Academy of Sciences, 2015)

The spiking activity of cortical neurons is highly variable. This variability is generally correlated among nearby neurons, an effect commonly interpreted to reflect the coactivation of neurons due to anatomically shared ...
