The identification of a neural circuit that drives a specific grooming movement in Drosophila reveals that it may also control movement parameters, such as duration.
Neuron ensembles in the medial prefrontal cortex gradually develop codes for relevant, latent variables common across multiple experiences while – apparently independently – losing information about irrelevant, contextual variables unique to each experience.
Midbrain dopamine neurons in rats signal discrepancies between predicted and actual rewards, regardless of whether the rewards are predicted on the basis of experience or inference.
Anatomically and physiologically distinct subpopulations of mechanosensory neurons on the fruit fly antennae elicit both common and distinct behavioral responses.
Zfp106 functions as an RNA binding protein, binds directly to GGGGCC RNA repeats, is required in motor neurons to prevent ALS-like neurodegeneration in mice, and can suppress neurotoxicity in an established fly model of ALS.
The neural circuit that regulates egg-laying behavior in nematode worms is activated by egg production, coupled to the circuit that generates movement, and inhibited by sensory feedback from egg release.
