The survival of Drosophila amacrine neurons is controlled by neurotrophic signaling mediated by interactions between the cell surface protein DIP-γ and its partner Dpr11, which is expressed on presynaptic photoreceptors.
The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.
Computational modeling and analysis of mouse neural population data finds that the excitation/inhibition imbalance theory of brain disorders is too limited to account for key changes in neural activity statistics.
Sensory neurons that monitor ambient oxygen control a cascade of responses across multiple layers of interneurons to switch the global state of the nematode C. elegans, reprogramming behavior and gene expression to enable escape from or adaptation to surface exposure.
The transcription factor CrebB mediates long-term memory formation in different neurons within the mushroom body learning circuit, including mushroom body intrinsic and output neurons but not dopaminergic input neurons.
