Reading population codes: a neural implementation of ideal observers.
Deneve S, Latham PE, Pouget A. Deneve S, et al. Among authors: pouget a. Nat Neurosci. 1999 Aug;2(8):740-5. doi: 10.1038/11205. Nat Neurosci. 1999. PMID: 10412064
Using simulations and analysis, we show that a close approximation to ML can be implemented in a biologically plausible model of cortical circuitry. Our results apply to a wide range of nonlinear activation functions, suggesting that cortical areas may, in ge …

Marginalization in neural circuits with divisive normalization.
Beck JM, Latham PE, Pouget A. Beck JM, et al. Among authors: pouget a. J Neurosci. 2011 Oct 26;31(43):15310-9. doi: 10.1523/JNEUROSCI.1706-11.2011. J Neurosci. 2011. PMID: 22031877 Free PMC article.
A wide range of computations performed by the nervous system involves a type of probabilistic inference known as marginalization. ...We show that when spike trains exhibit a particular type of statistics--associated with constant Fano factors and gain-invaria

Information-limiting correlations.
Moreno-Bote R, Beck J, Kanitscheider I, Pitkow X, Latham P, Pouget A. Moreno-Bote R, et al. Among authors: pouget a. Nat Neurosci. 2014 Oct;17(10):1410-7. doi: 10.1038/nn.3807. Epub 2014 Sep 7. Nat Neurosci. 2014. PMID: 25195105 Free PMC article.
Behavior and neural basis of near-optimal visual search.
Ma WJ, Navalpakkam V, Beck JM, Berg Rv, Pouget A. Ma WJ, et al. Among authors: pouget a. Nat Neurosci. 2011 Jun;14(6):783-90. doi: 10.1038/nn.2814. Epub 2011 May 8. Nat Neurosci. 2011. PMID: 21552276 Free PMC article.
The ability to search efficiently for a target in a cluttered environment is one of the most remarkable functions of the nervous system. ...In a target detection task, we randomly assigned high or low reliability to each item on a trial-by-trial basis. …

Optimal sensorimotor integration in recurrent cortical networks: a neural implementation of Kalman filters.
Denève S, Duhamel JR, Pouget A. Denève S, et al. Among authors: pouget a. J Neurosci. 2007 May 23;27(21):5744-56. doi: 10.1523/JNEUROSCI.3985-06.2007. J Neurosci. 2007. PMID: 17522318 Free PMC article.
Several behavioral experiments suggest that the nervous system uses an internal model of the dynamics of the body to implement a close approximation to a Kalman filter. This filter can be used to perform a variety of tasks nearly optimally, such as predicting …

Bayesian inference with probabilistic population codes.
Ma WJ, Beck JM, Latham PE, Pouget A. Ma WJ, et al. Among authors: pouget a. Nat Neurosci. 2006 Nov;9(11):1432-8. doi: 10.1038/nn1790. Epub 2006 Oct 22. Nat Neurosci. 2006. PMID: 17057707
Recent psychophysical experiments indicate that humans perform near-optimal Bayesian inference in a wide variety of tasks, ranging from cue integration to decision making to motor control. This implies that neurons both represent probability distributions and combine those …

Reference frames for representing visual and tactile locations in parietal cortex.
Avillac M, Denève S, Olivier E, Pouget A, Duhamel JR. Avillac M, et al. Among authors: pouget a. Nat Neurosci. 2005 Jul;8(7):941-9. doi: 10.1038/nn1480. Nat Neurosci. 2005. PMID: 15951810
A key issue is how VIP combines those inputs together. We mapped the visual and tactile receptive fields of multimodal VIP neurons in macaque monkeys trained to gaze at three different stationary targets. ...These findings are inconsistent with a remapping of all se

Neural correlations, population coding and computation.
Averbeck BB, Latham PE, Pouget A. Averbeck BB, et al. Among authors: pouget a. Nat Rev Neurosci. 2006 May;7(5):358-66. doi: 10.1038/nrn1888. Nat Rev Neurosci. 2006. PMID: 16760916 Review.
However, a complete understanding of neuronal variability, and, in particular, how it affects population codes, is missing. This is because variability in the brain is typically correlated, and although the exact effects of these correlations are not known, it is known tha …
