    Resting-state gamma-band power alterations in schizophrenia reveal E/I-balance abnormalities across illness-stages

    Tineke Grent-'t-Jong, Joachim Gross ... Peter J Uhlhaas
    Resting-state MEG-activity and MRS-GABA/Glx measurements reveal that there is a significant shift in excitability during the course of schizophrenia, involving hyperexcitability during the onset and a reduction at chronic stages.

    Beyond excitation/inhibition imbalance in multidimensional models of neural circuit changes in brain disorders

    Cian O'Donnell, J Tiago Gonçalves ... Terrence J Sejnowski
    Computational modeling and analysis of mouse neural population data finds that the excitation/inhibition imbalance theory of brain disorders is too limited to account for key changes in neural activity statistics.

    MicroRNA-138 controls hippocampal interneuron function and short-term memory in mice

    Reetu Daswani, Carlotta Gilardi ... Gerhard Schratt
    A new molecular mechanism involving microRNA, which controls synaptic transmission in a specialized type of inhibitory interneurons in the hippocampus and short-term memory in mice, was identified.
    1. Neuroscience

    Geometry and dynamics of representations in a precisely balanced memory network related to olfactory cortex

    Claire Meissner-Bernard, Friedemann Zenke, Rainer W Friedrich
    Computational modeling revealed that balanced assemblies of excitatory and inhibitory neurons shape representational manifolds in olfactory cortex-like recurrent networks, resulting in joint maps of sensory and semantic information.

    Assessing the balance between excitation and inhibition in chronic pain through the aperiodic component of EEG

    Cristina Gil Avila, Elisabeth S May ... Markus Ploner
    Multiverse analysis of the aperiodic component of the electroencephalography (EEG) power spectrum yielded robust evidence against a relationship to chronic pain, guiding further research on EEG biomarkers of chronic pain.

    Efficient analysis of mammalian polysomes in cells and tissues using Ribo Mega-SEC

    Harunori Yoshikawa, Mark Larance ... Angus I Lamond
    Translationally active polysomes from mammalian cells/tissues are successfully separated with rapidity, high efficiency and exceptional reproducibility by a SEC-based approach, an accessible alternative to the conventional sucrose density gradient analysis.

    The aperiodic exponent of subthalamic field potentials reflects excitation/inhibition balance in Parkinsonism

    Christoph Wiest, Flavie Torrecillos ... Huiling Tan
    The slope of the power spectrum of subthalamic local field potentials tracks pathological states in Parkinson’s disease and likely complements beta activity as a feedback marker for adaptive deep brain stimulation.

    Meta-analysis reveals glucocorticoid levels reflect variation in metabolic rate, not ‘stress’

    Blanca Jimeno, Simon Verhulst
    Glucocorticoids are assumed to reflect 'stress,' but they increase proportionally to the increase in metabolic rate induced by stressors, leading us to propose that glucocorticoids reflect metabolic rate, not stress.
    1. Neuroscience

    Optimal compensation for neuron loss

    David GT Barrett, Sophie Denève, Christian K Machens
    Spiking networks compensate the loss of neurons instantaneously, when restoration of excitatory/inhibitory balance becomes equivalent to restoration of functionality.
    1. Neuroscience

    Learning excitatory-inhibitory neuronal assemblies in recurrent networks

    Owen Mackwood, Laura B Naumann, Henning Sprekeler
    The synaptic structure in mouse V1 is explained by a synergy of homeostatic plasticity in incoming and outgoing synapses of inhibitory interneurons, establishing a stimulus-specific balance of excitation and inhibition.
