Estimating relative velocity in the natural environment is challenging because natural scenes vary greatly in contrast and spatial structure. Widely accepted correlation-based models for elementary motion detectors (EMDs) are sensitive to contrast and spatial structure and consequently generate ambiguous estimates of velocity. Identified . . . → Read More: Motion Adaptation and the Velocity Coding of Natural Scenes

Background

Breaking cell symmetry, known as polarization, requires dynamic reorganization of microtubules (MTs) and is essential to many cellular processes, including axon formation in neurons. A critical step in polarization is believed to be the “selective stabilization” of MTs, which hypothesizes a spatial and/or temporal shift . . . → Read More: Cell-Length-Dependent Microtubule Accumulation during Polarization

Background

Total food intake is a function of meal size and meal frequency, and adjustments to these parameters allow animals to maintain a stable energy balance in changing environmental conditions. The physiological mechanisms . . . → Read More: The Leucokinin Pathway and Its Neurons Regulate Meal Size in Drosophila
