    Central neural circuitry mediating courtship song perception in male Drosophila

    Chuan Zhou et al.
    Anatomical, behavioral and physiological evidence suggests that the aPN1-vPN1-pC1 pathway serves as a labeled line for the processing and transformation of courtship song in male Drosophila.

    A predictive focus of gain modulation encodes target trajectories in insect vision

    Steven D Wiederman et al.
    Visual neurons in the dragonfly predict the path of a moving target, even when it is occluded or crosses from one eye to the other.

    Evolutionary changes in transcription factor coding sequence quantitatively alter sensory organ development and function

    Simon Weinberger et al.
    The coding sequences of a very highly conserved family of neurogenic transcription factors from different species have evolved to generate proteins that have different life times causing them to display quantitatively different neural induction potentials.

    Cortex commands the performance of skilled movement

    Jian-Zhong Guo et al.
    Optogenetic inhibition demonstrates that the cortex is necessary and sufficient for the initiation and execution of a learned, skilled action.

    A frontal cortex event-related potential driven by the basal forebrain

    David P Nguyen, Shih-Chieh Lin
    Contrary to the common belief that cognitive event-related potentials are generated by local activity within the cerebral cortex, it is shown that some of these potentials are modulated by subcortical inputs.

    Cortex-wide BOLD fMRI activity reflects locally-recorded slow oscillation-associated calcium waves

    Miriam Schwalm et al.
    Locally recorded calcium events related to slow wave activity show a global cortical fMRI BOLD correlate, establishing a direct relation between a basic neurophysiological signal and the macroscopic perspective of pre-clinical fMRI.

    Neurophysiological evidence of efference copies to inner speech

    Thomas J Whitford et al.
    The silent production of words in one's mind generates an efference copy that is similar in nature to the efference copy associated with overt vocalization.

    Neurogenetic dissection of the Drosophila lateral horn reveals major outputs, diverse behavioural functions, and interactions with the mushroom body

    Michael-John Dolan et al.
    The generation and systematic characterisation of driver lines labelling a large number of neurons in the Drosophila innate olfactory processing centre bridges electron microscopy neuronal reconstructions, circuits and behaviour.

    Functional clustering of dendritic activity during decision-making

    Aaron Kerlin et al.
    In motor cortex pyramidal neurons, diverse task-related signals are distributed throughout the dendritic arbor and compartmentalized by dendritic distance and branching.

    Ventrolateral periaqueductal gray neurons prioritize threat probability over fear output

    Kristina M Wright, Michael A McDannald
    Single-unit activity in the ventrolateral periaqueductal gray, a brain region implicated in organizing fear output, is found to reflect threat probability, a more versatile threat signal.
