The nervous system can learn to control standing balance with added sensorimotor delays by causally linking delayed whole-body sensory feedback, initially deemed as unexpected, to self-generated balance motor commands.
Animals work in a world full of surprises, where using energy to position sensors proportional to the location's expected information avoids the pitfalls of positioning them at the information maxima.

A fast spiking interneuron sub-type in medial and lateral prefrontal cortex fires and gamma-synchronizes prominently during adaptive learning of reward values when outcomes are uncertain and choice options have similar values.

Human path integration accuracy is strongly influenced by the underlying control dynamics, but less so when visual, rather than vestibular, feedback is available.
Combining 7 Tesla fMRI and MEG data collected during a challenging visual recognition task revealed distinct neural representational formats in ventral visual and frontoparietal regions, and the emergence of recognition-related signals prior to category-related information.
Movement biases due to recent action history involve both dynamically-evolving processes reflecting prediction of future actions, and temporally-stable processes induced by movement repetition.

Touch-mediated social interactions in human females elicited endogenous oxytocin and brain responses in a covariant manner, and these changes were modulated by the familiarity of the person delivering touch as well as the recent history of social interaction.
Stunning new scan data of an enigmatic fish from the Early Devonian of Australia, Ligulalepis, is identified as a stem osteichthyan, specifically, as the sister taxon to the 'psarolepids' plus crown osteichthyans.
Computational modeling, and empirical behavioral and EEG results show that learning relies not only on comparing current events to past experience, but integrates response-based outcome predictions and confidence.
