    Orbital frontal cortex updates state-induced value change for decision-making

    Emily T Baltz, Ege A Yalcinbas ... Christina M Gremel
    Orbital frontal cortex projection neuron activity is necessary to update state-dependent value change to control model-based behavior.

    Coherent theta activity in the medial and orbital frontal cortices encodes reward value

    Linda M Amarante, Mark Laubach
    The more you want it or the better it is, the stronger is medial frontal theta (paraphrased from a retweet of the preprint by Dr James Hyman).

    Neural activity ramps in frontal cortex signal extended motivation during learning

    Josue M Regalado, Ariadna Corredera Asensio ... Priyamvada Rajasethupathy
    Motivated animals learn to put in more effort and ignore distractions to reach their goals due to increased neural activity in the frontal cortex.

    Mechanism for differential recruitment of orbitostriatal transmission during actions and outcomes following chronic alcohol exposure

    Rafael Renteria, Christian Cazares ... Christina M Gremel
    Chronic alcohol exposure results in a long-lasting, enhanced endocannabinoid signalling at orbitostriatal synapses that is expressed in a projection-, synapse-, and behaviorally computation-specific manner.

    Neural geometry from mixed sensorimotor selectivity for predictive sensorimotor control

    Yiheng Zhang, Yun Chen ... He Cui
    Target motion modulates monkey M1 neural dynamics during reaching, characterized by an orbital neural geometry composed of target-velocity-dependent tilting rings, suggesting that sensory information can be independently incorporated during motor generation.

    Broca’s area, variation and taxic diversity in early Homo from Koobi Fora (Kenya)

    Amélie Beaudet, Edwin de Jager
    A computer-assisted revision of a unique fossil from Kenya supports the hypothesis that the modern features of our brain emerged recently in the human evolutionary history.

    1. Neuroscience

    The shared and unique neural correlates of personal semantic, general semantic, and episodic memory

    Annick FN Tanguay, Daniela J Palombo ... Louis Renoult
    Four types of declarative memory rely on different weightings of similar component processes, according to fMRI and subjective ratings.
    1. Neuroscience

    When abstract becomes concrete, naturalistic encoding of concepts in the brain

    Viktor Nikolaus Kewenig, Gabriella Vigliocco, Jeremy I Skipper
    A novel deep-learning-based computational method using object recognition to quantify visual context in naturalistic, multimodal stimuli demonstrates that a concept's perceived abstractness or concreteness dynamically depends on its visual context.
    1. Neuroscience

    Dichotomous organization of amygdala/temporal-prefrontal bundles in both humans and monkeys

    Davide Folloni, Jerome Sallet ... Rogier B Mars
    Amygdala/temporal-prefrontal cortex fibers are organised in separate amygdalofugal and uncinate bundles in humans and macaques, shaping the anatomical foundation for decision-making and socio-emotional behaviour.
    1. Neuroscience

    Perceptual coupling and decoupling of the default mode network during mind-wandering and reading

    Meichao Zhang, Boris C Bernhardt ... Elizabeth Jefferies
    Functional neuroimaging in the human brain reveals the neurocognitive mechanisms that underpin the experience of mind-wandering during reading, explaining why comprehension is impaired.
