Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.
A series of genetically-encoded fluorescent reporters that allow imaging of neuropeptide release in vivo, with sub-second temporal and nerve terminal-level spatial resolution are developed.
Fluorescence lifetime imaging microscopy, paired with fluorescent, voltage-sensitive dyes, provides a method for measuring and quantifying membrane potentials of living cells.
Similar to spontaneous eye blinks perceptual stability, despite small saccades, is related to actively silencing transients in the high-level ends of both ventral and dorsal visual cortices, while activity in low-level visual cortex remains unstable.
High-resolution live imaging analysis shows a constriction mechanism that drives zebrafish optic cup morphogenesis and highlights the role of the extracellular matrix in transmitting tensions beyond the cellular level.
The selective effect of local inhibition on diffuse patterns of brain connectivity can be accounted for by an intrinsic hierarchical ordering of cortical timescales.
TRPV4 channels in brain capillaries are suppressed by the phosphoinositide PIP2 and activated by receptor agonists implicated in neurovascular coupling.
