The fruit fly estimates visual motion by incorporating ON-OFF asymmetric processing that only improves performance when stimuli have light-dark asymmetries matched to natural scenes.
Neurons differ in their impact on collective cortical activity, with sensitive neurons forming a stable topological core, implicated in cortical-state transitions, while peripheral insensitive neurons are more responsive to stimuli.
The probability of occupancy of individual synaptic release sites at rest sets an upper limit to synaptic output when increasing action potential related calcium entry.
Association of curvature generating proteins to the Golgi membranes by sphingomyelin metabolism essentially controls the flatness of a Golgi cisterna that is necessary for efficient sorting and export.
Advanced microscopy techniques reveal that clusters of Pom1 kinase at the membrane represent the functional unit that shape the concentration gradients and modulate Pom1 mid-cell levels according to cell size.
Animals work in a world full of surprises, where using energy to position sensors proportional to the location's expected information avoids the pitfalls of positioning them at the information maxima.
Structural and functional analyses show that transverse tubule association with stacks of sarcoplasmic reticulum enhances Orai1-dependent Ca2+ entry to replenish Ca2+ stores, maintain Ca2+ release, and maximize force during exercise.
Computer simulations of the evolution of broadly neutralizing antibodies against HIV suggest that non-traditional pathways involving framework mutations which lead initially to increased antibody flexibility do occur, but can be avoided by appropriate vaccine design.
High-resolution live imaging reveals how and when the mouse heart first starts to beat during development and how the onset of beating impacts on heart muscle cell maturation and heart formation.
Increased spontaneous calcium activity in Rett syndrome astrocytes is a key cell-autonomous phenotype that affects synaptic function and network activity.
