The paper shows that locust swarming evolves through diverse molecular pathways rather than shared genes, highlighting flexible regulatory architectures and modular systems.

The paper maps retinal ganglion cell functional diversity in the mouse superior colliculus and identifies specialized response types for collision detection.

This study compares phenotypic plasticity effects on jump escape behavior and LGMD neuron properties in locusts and grasshoppers, finding behavioral differences but not physiological or transcriptomic ones.

The paper characterizes a Shaker potassium channel in a grasshopper neuron involved in visual object segmentation through electrophysiology and computational modeling.

The paper compares how grasshoppers and goldfish detect collisions with accelerating vs. constant-speed stimuli, finding differences in neural sensitivity but similar escape behavior outcomes.

The paper tests how neuronal collision-avoidance models respond to accelerating versus constant-speed approaching objects, finding that predictions hold for some models but not others.

The paper shows that the synaptic mapping of excitatory inputs in a grasshopper neuron affects its ability to discriminate stimulus coherence and influences escape behavior.

The paper investigates the role of ON and OFF motion detection pathways in Drosophila's escape behavior to looming stimuli, finding that inactivating these pathways selectively reduces escape responses to light or dark looming.

The paper investigates how active membrane conductances and dendritic morphology in a grasshopper neuron influence synaptic integration and membrane synchrony.

The paper demonstrates the use of Semliki Forest virus to deliver channelrhodopsin into locust optic lobe neurons, enabling optogenetic manipulation and activation of medullary neurons and their postsynaptic targets.

The paper investigates the role of M-current in a collision detecting neuron, showing it regulates firing mode and spike reliability to enhance collision detection.

The paper shows feed-forward inhibition in a locust collision detection circuit encodes time-varying stimulus information, contributing to firing rate dynamics critical for escape behavior.

The paper investigates presynaptic circuits that contribute to visual object segmentation during collision avoidance by identifying muscarinic lateral excitation as a key mechanism.

The paper shows a collision-detecting neuron in grasshoppers uses dendritic channels to segment objects and guide escape behavior.
