    MTL neurons phase-lock to human hippocampal theta

    Daniel R Schonhaut, Aditya M Rao ... Michael J Kahana
    Neural spiking throughout the MTL is synchronous with hippocampal theta phase during spatial memory and navigation experiments in humans, even after controlling for phase-coupling to local theta oscillations.

    Emotional learning retroactively promotes memory integration through rapid neural reactivation and reorganization

    Yannan Zhu, Yimeng Zeng ... Shaozheng Qin
    Emotional learning retroactively promotes memory integration for previously neutral events into episodic memory to foster future event predictions, through rapidly stimulating trial-specific reactivation of overlapping memory traces and reorganization of associated memories among the amygdala, hippocampal, and neocortical circuits.

    Principles for coding associative memories in a compact neural network

    Christian Pritz, Eyal Itskovits ... Alon Zaslaver
    A compact neural network can form various associative memories that are encoded in a distributed manner, where each neuron stores different components of the memory.

    Mechanical activation of TWIK-related potassium channel by nanoscopic movement and rapid second messenger signaling

    E Nicholas Petersen, Mahmud Arif Pavel ... Scott B Hansen
    Cells utilize a membrane-mediated mechanism for mechanosensation, which involves the disruption of lipid rafts and a signal relayed to an ion channel.

    Network structure of brain atrophy in de novo Parkinson's disease

    Yashar Zeighami, Miguel Ulla ... Alain Dagher
    The pattern of atrophy in Parkinson's disease is consistent with the disease spreading via intrinsic brain networks.

    The genetic factors of bilaterian evolution

    Peter Heger, Wen Zheng ... Thomas Wiehe
    Advanced orthology clustering of bilaterian and non-bilaterian sequences identifies 157 bilaterian-specific genes which are linked to key morphological features of this animal group.

    Amphetamine reduces reward encoding and stabilizes neural dynamics in rat anterior cingulate cortex

    Saeedeh Hashemnia, David R Euston, Aaron J Gruber
    Amphetamine reduces reward signaling by neurons in rat prefrontal cortex, but increases the stability of population dynamics, which account for animals’ increased task engagement, despite reduced reward motivation.

    Nucleus accumbens dopamine tracks aversive stimulus duration and prediction but not value or prediction error

    Jessica N Goedhoop, Bastijn JG van den Boom ... Ingo Willuhn
    The extracellular concentration of dopamine in the nucleus accumbens core is progressively diminished by white noise, an underutilized, easy-to-titrate aversive stimulus, but is unaffected by white-noise intensity, context valence, and associated probabilistic contingencies.

    Microbiota-driven transcriptional changes in prefrontal cortex override genetic differences in social behavior

    Mar Gacias, Sevasti Gaspari ... Patrizia Casaccia
    Gut microbiota can influence mPFC transcriptional profiles and myelin content, overriding the impact of genetic background in the development of social avoidance behavior.

    Thirst interneurons that promote water seeking and limit feeding behavior in Drosophila

    Dan Landayan, Brian P Wang ... Fred W Wolf
    Thirsty seeking interneurons in Drosophila differentially regulate water intake and feeding behavior.
