    The comprehensive connectome of a neural substrate for ‘ON’ motion detection in Drosophila

    Shin-ya Takemura et al.
    Connectomic analysis identifies the complex circuits of a visual motion-sensing neuron that qualify them to generate direction-selective motion sensing signals using both Hassenstein-Reichardt and Barlow-Levick models.

    Mushroom body output neurons encode valence and guide memory-based action selection in Drosophila

    Yoshinori Aso et al.
    Output neurons in the mushroom body of the fruit fly brain encode the positive or negative survival value of stimuli, enabling insects to choose adaptive approach and avoidance behaviors through associative learning.

    Identification of motor neurons and a mechanosensitive sensory neuron in the defecation circuitry of Drosophila larvae

    Wei Zhang et al.
    The neural circuit underlying defecation behavior in Drosophila larvae has been identified and characterized.

    Sequential selection of economic good and action in medial frontal cortex of macaques during value-based decisions

    Xiaomo Chen, Veit Stuphorn
    Whenever monkeys are required to choose between multiple options, neural responses indicate that they first select the desired outcome and then use this information to guide their actions.

    Motor selection dynamics in FEF explain the reaction time variance of saccades to single targets

    Christopher K Hauser et al.
    Oculomotor circuits are always busy planning the next eye movement, and this explains why, when a visual target appears, some eye movements toward it are produced very quickly whereas others take a long time to prepare.

    Deletion of a kinesin I motor unmasks a mechanism of homeostatic branching control by neurotrophin-3

    Thomas O Auer et al.
    Disrupting synapse formation between the retina and the brain in zebrafish larvae-by eliminating the molecular motor Kif5A-triggers a compensatory increase in the branching of retinal axons aimed at restoring synapse number.

    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.
    1. Neuroscience

    A suppression hierarchy among competing motor programs drives sequential grooming in Drosophila

    Andrew M Seeds et al.
    Gaining genetic control over neural modules that drive the grooming of each Drosophila body part reveals how mechanisms for selecting among competing behavioral choices are used to generate sequences of actions.
    1. Neuroscience

    A common directional tuning mechanism of Drosophila motion-sensing neurons in the ON and in the OFF pathway

    Juergen Haag et al.
    A common mechanism for computation of direction selectivity in the ON and OFF channel is demonstrated.
