fMRI evidence for off-task replay predicts subsequent replanning behavior in humans, suggesting that learning from simulated experience during replay helps update past policies in reinforcement learning.
Building on previous work (Aso et al., 2014a; Aso et al., 2014b), cell-type-specific drivers and optogenetics are used to control the local release of dopamine and reveal that distinct learning rules are implemented in parallel memory units.
CaImAn is an open-software package that equips the neuroscience community with a set of turnkey, fast and scalable solutions to pre-processing problems arising in single cell calcium imaging data analysis.
Despite ongoing rewiring and continuous turnover of synapses, a computational model shows that memories can maintain and even strengthen their connectivity by self-reactivating during periods without sensory input.
By combining ultra-high-field imaging with physiological and saliva measures it is established that interactions between locus coeruleus, hippocampus and amygdala vary along emotional memory stages, putatively reflecting distinct cognitive states.
The readiness potential—a long-established neural precursor of voluntary action claimed to precede the onset of the conscious decision to move—is absent, or at least significantly reduced, for deliberate decisions.
