Discrete attractor dynamics underlies persistent activity in the frontal cortex

HK Inagaki, L Fontolan, S Romani, K Svoboda - Nature, 2019 - nature.com
Short-term memories link events separated in time, such as past sensation and future
actions. Short-term memories are correlated with slow neural dynamics, including selective …

Uncertainty, epistemics and active inference

T Parr, KJ Friston - Journal of the Royal Society Interface, 2017 - royalsocietypublishing.org

Noise in neural populations accounts for errors in working memory

PM Bays - Journal of Neuroscience, 2014 - Soc Neuroscience
Errors in short-term memory increase with the quantity of information stored, limiting the
complexity of cognition and behavior. In visual memory, attempts to account for errors in …

Internally organized mechanisms of the head direction sense

A Peyrache, MM Lacroix, PC Petersen… - Nature neuroscience, 2015 - nature.com
The head-direction (HD) system functions as a compass, with member neurons robustly
increasing their firing rates when the animal's head points in a specific direction. HD …
