    Neural encoding of task-dependent errors during adaptive learning

    Chang-Hao Kao, Sangil Lee ... Joseph W Kable
    Posterior parietal cortex encodes errors in a task-dependent manner while a large array of frontal regions predict subsequent behavioral changes in response to ambiguous errors.

    Behavioral training promotes multiple adaptive processes following acute hearing loss

    Peter Keating, Onayomi Rosenior-Patten ... Andrew J King
    Training enables adult humans to rapidly adapt their sound localization abilities to unilateral hearing loss by combining different strategies that rely on partially distinct neurophysiological substrates.

    Adaptive learning and decision-making under uncertainty by metaplastic synapses guided by a surprise detection system

    Kiyohito Iigaya
    Computational modeling offers an explanation for why animals learn more quickly or slowly when their environment becomes more variable or stable.

    Learning-related contraction of gray matter in rodent sensorimotor cortex is associated with adaptive myelination

    Tomas Mediavilla, Özgün Özalay ... Daniel J Marcellino
    Learning produces dynamic white matter volumetric changes in the rodent brain observed by voxel-based morphometry on longitudinal structural MRI for which estimated white matter volume reflects adaptive myelination in the cortex.

    Fixation-pattern similarity analysis reveals adaptive changes in face-viewing strategies following aversive learning

    Lea Kampermann, Niklas Wilming ... Selim Onat
    A novel approach based on eye-movement patterns reveals adaptive changes during viewing of faces and fear generalization.

    Rapid learning and unlearning of predicted sensory delays in self-generated touch

    Konstantina Kilteni, Christian Houborg, H Henrik Ehrsson
    The brain continuously updates the learned temporal relationship between motor commands and their associated somatosensory feedback, which determines the perceived intensity and ticklishness of self-touch.

    A unified neural account of contextual and individual differences in altruism

    Jie Hu, Arkady Konovalov, Christian C Ruff
    Individual and situational differences in altruistic behavior do not reflect use of fundamentally different decision mechanisms, but instead differences in early perceptual or attentional processing of the choice-relevant information.

    Detecting adaptive introgression in human evolution using convolutional neural networks

    Graham Gower, Pablo Iáñez Picazo ... Fernando Racimo
    Convolutional neural networks are an effective tool for detecting archaic adaptive introgression from genomic data.

    Shared mechanisms of auditory and non-auditory vocal learning in the songbird brain

    James N McGregor, Abigail L Grassler ... Samuel J Sober
    A novel, non-auditory learning paradigm reveals that songbirds can modify their vocal output based on somatosensory signals and that a common set of brain pathways underlies both this form of vocal learning and auditory-guided vocal learning.
    1. Neuroscience

    On the normative advantages of dopamine and striatal opponency for learning and choice

    Alana Jaskir, Michael J Frank
    A computational model of the opponent neural architecture the basal ganglia, in tandem with adaptive dopamine modulation, exhibits robust advantages over traditional learning algorithms and ties together seemingly aberrant behavioral patterns resulting from dopamine and environmental manipulations across species.
