Statistically optimal perception and learning: from behavior to neural representations
Human perception has recently been characterized as statistical inference based on noisy
and ambiguous sensory inputs. Moreover, suitable neural representations of uncertainty …

Neuromodulation of the feedforward dentate gyrus-CA3 microcircuit
The feedforward dentate gyrus-CA3 microcircuit in the hippocampus is thought to activate
ensembles of CA3 pyramidal cells and interneurons to encode and retrieve episodic …

An effect of serotonergic stimulation on learning rates for rewards apparent after long intertrial intervals
Serotonin has widespread, but computationally obscure, modulatory effects on learning and
cognition. Here, we studied the impact of optogenetic stimulation of dorsal raphe serotonin …

Forward and backward inference in spatial cognition
This paper shows that the various computations underlying spatial cognition can be
implemented using statistical inference in a single probabilistic model. Inference is …

Bayesian models of brain and behaviour
W Penny - International Scholarly Research Notices, 2012 - Wiley Online Library
This paper presents a review of Bayesian models of brain and behaviour. We first review the
basic principles of Bayesian inference. This is followed by descriptions of sampling and …

Top-down feedback in an HMAX-like cortical model of object perception based on hierarchical Bayesian networks and belief propagation
S Dura-Bernal, T Wennekers, SL Denham - PloS one, 2012 - journals.plos.org
Hierarchical generative models, such as Bayesian networks, and belief propagation have
been shown to provide a theoretical framework that can account for perceptual processes …

Optimal recall from bounded metaplastic synapses: predicting functional adaptations in hippocampal area CA3
A venerable history of classical work on autoassociative memory has significantly shaped
our understanding of several features of the hippocampus, and most prominently of its CA3 …

Associative memory of phase-coded spatiotemporal patterns in leaky Integrate and Fire networks
S Scarpetta, F Giacco - Journal of Computational Neuroscience, 2013 - Springer
We study the collective dynamics of a Leaky Integrate and Fire network in which precise
relative phase relationship of spikes among neurons are stored, as attractors of the …
