    Peripheral optogenetic stimulation induces whisker movement and sensory perception in head-fixed mice

    Sunmee Park, Akhil Bandi ... David J Margolis
    Light can be used to trigger the contraction of facial muscles and movement of the whiskers in transgenic mice, aiding the study of active sensation.

    Distinct forms of synaptic plasticity during ascending vs descending control of medial olivocochlear efferent neurons

    Gabriel E Romero, Laurence O Trussell
    In a fast brainstem relay controlling hearing sensitivity, descending synaptic control from midbrain provides the dominant source of excitation, due to a distinct form of synaptic plasticity.

    Synapse-specific opioid modulation of thalamo-cortico-striatal circuits

    William T Birdsong, Bart C Jongbloets ... Tianyi Mao
    By differentially modulating the two major excitatory inputs to the striatum, mu- and delta-opioid receptors regulate the balance between thalamic and cortical inputs to the striatum.

    The crystal structure of bromide-bound GtACR1 reveals a pre-activated state in the transmembrane anion tunnel

    Hai Li, Chia-Ying Huang ... John L Spudich
    Substrate-induced structural changes in GtACR1 provide new insight into the chemical mechanism of natural light-gated anion conductance and facilitate its optimization for photoinhibition of neuron firing in optogenetics.

    Hippocampal low-frequency stimulation prevents seizure generation in a mouse model of mesial temporal lobe epilepsy

    Enya Paschen, Claudio Elgueta ... Carola A Haas
    Optogenetic and electrical low-frequency stimulation in the sclerotic hippocampus prevents the emergence of spontaneous focal and evoked generalized seizures in a mouse epilepsy model.

    Respiratory alkalosis provokes spike-wave discharges in seizure-prone rats

    Kathryn A Salvati, George MPR Souza ... Mark P Beenhakker
    Respiratory alkalosis recruits the midline thalamus to provoke absence seizures.

    Experience-dependent weakening of callosal synaptic connections in the absence of postsynaptic FMRP

    Zhe Zhang, Jay R Gibson, Kimberly M Huber
    Postnatal, postsynaptic loss of FMRP specifically weakens callosal synaptic inputs onto L2/3 pyramidal neurons, in requirement ofnormal sensory experience, through downregulating AMPA receptor transmission and without affecting local synaptic inputs during cortical circuit development.

    Cerebrospinal fluid-contacting neuron tracing reveals structural and functional connectivity for locomotion in the mouse spinal cord

    Yuka Nakamura, Miyuki Kurabe ... Masaki Ueno
    Newly developed methods to genetically target cerebrospinal fluid-contacting neurons reveal unique caudorostrally extended projections and recurrent connections in the spinal motor circuitry to control locomotion in mice.

    Dynamical feature extraction at the sensory periphery guides chemotaxis

    Aljoscha Schulze, Alex Gomez-Marin ... Matthieu Louis
    A computational model for the control of chemotaxis in the Drosophila larva clarifies the link between the peripheral encoding of naturalistic olfactory stimuli and action selection.
