A sexually dimorphic circuit node controls a persistent, internal state that promotes fighting and mating in Drosophila, revealing parallels with mammalian systems suggestive of a conserved circuit "motif" controlling social behaviors.
The auditory cortex temporarily stores task-relevant information by persistently changed neuronal activity of single neurons and of neuronal populations.
Building on previous work (Huang et al., 2016), we show that translational control by p-eIF2α is a defense mechanism that prevents persistent cocaine-induced synaptic synaptic potentiation underlying compulsive drug seeking.
Combination of in vitro and in vivo approaches reveal how learning suppresses the microRNA system to trigger de novo synthesis of plasticity proteins, a missing link in the current model of microRNA-mediated translation in persistent synaptic plasticity and memory.
Neural activity in the rat nucleus accumbens provides a rich task representation that includes not only expected outcomes, but also the specific identity of the cues that predict these outcomes.
A fundamental lower-bound on memory recall precision, which declines with storage duration and number of stored items, is derived, and human performance is shown to be well-fit by this theoretical bound.
The analysis of 18th century Y. pestis genomes reveals a bacterial lineage that might be responsible for the 400-year period of European plague epidemics from the Renaissance through early modern times.
When Rhesus monkeys plan reaching movements of which they are not fully confident, a particular area of the brain represents both the chosen action as well as alternate movements, perhaps as an aid for error correction or learning.
