    Perception as a closed-loop convergence process

    Ehud Ahissar, Eldad Assa
    Perception is proposed to be a dynamic motor-sensory closed-loop process in which information flows through the environment and the brain in continuous loops, converging towards steady-state percepts.

    Closed-loop auditory stimulation method to modulate sleep slow waves and motor learning performance in rats

    Carlos G Moreira, Christian R Baumann ... Daniela Noain
    Delivery of auditory triggers as unique slow waves-targeting approach yields efficient, stable, and precise modulation of slow-wave activity in rats.

    Interactions between circuit architecture and plasticity in a closed-loop cerebellar system

    Hannah L Payne, Jennifer L Raymond, Mark S Goldman
    A comprehensive modeling approach reconciles experimental observations with classic plasticity mechanisms in the cerebellar cortex, demonstrating how learning-related changes in neural activity can appear to contradict the sign of the underlying plasticity when feedback is present.

    Analogue closed-loop optogenetic modulation of hippocampal pyramidal cells dissociates gamma frequency and amplitude

    Elizabeth Nicholson, Dmitry A Kuzmin ... Dimitri Michael Kullmann
    Neurons can synchronize, supporting flexible communication among brain areas; closed-loop optogenetics allows the frequency and power of population oscillations to be dissociated, providing a tool to interrogate how networks couple.

    Real-time classification of experience-related ensemble spiking patterns for closed-loop applications

    Davide Ciliberti, Frédéric Michon, Fabian Kloosterman
    A brain–computer interface for real-time identification of transient neural activity patterns enables causal inference of the role of these patterns in cognition through closed-loop manipulation.

    The ribosomal protein Asc1/RACK1 is required for efficient translation of short mRNAs

    Mary K Thompson, Maria F Rojas-Duran ... Wendy V Gilbert
    Asc1/RACK1 promotes the translation of mRNAs associated with the translational closed loop complex, which have short open reading frames and encode proteins required for core metabolic processes.

    Closed-loop neuromodulation restores network connectivity and motor control after spinal cord injury

    Patrick D Ganzer, Michael J Darrow ... Robert L Rennaker II
    Precisely-timed bursts of closed-loop vagus nerve stimulation during rehabilitation restore neural connectivity and substantially improve recovery of motor function after SCI.
    1. Neuroscience

    Coding of latent variables in sensory, parietal, and frontal cortices during closed-loop virtual navigation

    Jean-Paul Noel, Edoardo Balzani ... Dora E Angelaki
    Primates use their eyes to keep track of spatial goals, and this strategy is reflected by the functional connectivity between a traditionally considered optic flow area (dorsomedial superior temporal area) and prefrontal cortex.

    Disruption of awake sharp-wave ripples does not affect memorization of locations in repeated-acquisition spatial memory tasks

    Lies Deceuninck, Fabian Kloosterman
    Hippocampal sharp-wave ripples are not required for rats to successfully perform spatial tasks that rely on memorization of locations at short timescales.
    1. Neuroscience

    optoPAD, a closed-loop optogenetics system to study the circuit basis of feeding behaviors

    José-Maria Moreira, Pavel M Itskov ... Carlos Ribeiro
    The optoPAD system combines real-time behavioral analysis with optogenetic manipulations to study how animals adapt to dynamic gustatory environments and to identify the circuit basis of feeding.
