Alternating sequences of future and past behavior encoded within hippocampal theta oscillations
Science 107d 8 tweets
Adaptive behavior requires the ability to analyze experience both prospectively and retrospectively. How can forward-ordered neural activity facilitate the storage or expression of reverse-ordered sequences? Wang et al. used multitetrode recordings...

Abstract. A cognitive map, representing an environment around oneself, is necessary for spatial navigation. However, compared with its constituent elements suc
Polarity of uncertainty representation during exploration and exploitation in ventromedial prefrontal cortex
Nature Human Behaviour 145d 3 tweets
Trudel et al. find that the ventromedial prefrontal cortex carries multiple decision variables, the strength and polarity of which vary according to their relevance to the context of exploration, exploitation and the transition between these states.
