Chromosome segregation in male spermatocytes exhibits anaphase A without shortening of autosome-associated microtubules and partitioning of an unpaired X chromosome that is initiated by an imbalance of attached kinetochore microtubules.
Postsynaptic MT1-MMP serves as a molecular switch to synaptogenesis by clearing the surrounding ECM environment that allows effective deposition of nerve-derived synaptogenic factors to induce postsynaptic differentiation at developing NMJs.
Structural brain plasticity is encoded in the topographic distribution of Toll receptors and their ability to switch between alternative signalling outcomes, thus translating diverse sensory experience into structural change.
Novel transgenic zebrafish lines allow selective ablation of neuronal mitochondria by far red light, providing a powerful tool for investigating mitochondrial homeostasis in neurons and mitochondrial mechanisms in neurological disease.
Accurate direction-selective information is present within small sections of the dendrites, raising the possibility that single dendrites utilize parallel processing schemes to process motion information.
