Positive feedback between contractile ring myosin and compression-driven cortical flow can explain the exponential accumulation of contractile ring components and constriction rate acceleration that ensures timely cell separation during cytokinesis.

Cortical astrocytes play key roles in NREM sleep by regulating sleep depth and duration through separate GPCR pathways, and differentially control neuronal slow-wave activity in local and remote cortical circuits.

The different laminar profiles observed across the cortical depth for multisensory and attentional influences indicate partly distinct neural circuitries of information-flow control.

Experiments reveal mechanisms through which Caenorhabditis elegans zygotes depleted of Aurora A or lacking centrosomes spontaneously establish two posterior PAR-2 domains, one at each pole, in a curvature-dependent manner.

Oon and Prehoda discover cortical actomyosin dynamics that polarize asymmetrically dividing neural stem cells.

A neural circuit that can selectively induce sleep-like patterns in small regions of the brain demonstrates how sleep and arousal states may be controlled in local brain regions.

Patterns of communication between the thalamus and the cortex are correlated with anesthesia-induced loss of consciousness and recovery.

While perceptual content is encoded in non-oscillatory activity in the slow cortical potential (<5 Hz) range, perceptual stability is predominantly influenced by the amplitude fluctuations of alpha (~10 Hz) and beta (~20 Hz) brain oscillations.

Population cortical recordings and computational network modeling support a novel mechanism underlying spontaneous UP-DOWN dynamics consisting on non-rhythmic transitions between a silent attractor and a low-rate inhibition-stabilized attractor.

It is shown that fission yeast cells sense their size by measuring their surface area through a membrane-associated sizer protein cdr2p.
