Fast fluctuations of oxygen, linked to behavioral and neural dynamics in vivo, cause phasic transients is amperometry-measured cholinergic signals via the mechanism of non-steady-state enzyme kinetics in the choline-oxidase-based biosensor.
An atomic model of the bacterial chemosensory array obtained through the synthesis of cryo-electron tomography and large-scale molecular-dynamics simulations reveals a new kinase conformation during signaling events.
The spatial and dynamic properties of self-motion signals are acquired at the first stage of otolith signal transformation, which is in the brainstem and cerebellum, and conserved across brainstem, cerebellar and cortical areas.
An individual extracellular signal regulates multiple cellular actions through differences in the temporal dynamics of spatially distinct populations of the central signaling enzyme, extracellular-signal regulated kinase.
Genomic analysis of Xenopus gastrula reveal that the transcription factor Sox17 interacts with the Wnt signaling effector ß-catenin on enhancers to regulate the transcriptional program underlying endoderm germ layer formation.
In contrast to perception, during visual imagery, there are no clear time-locked processing stages and imagery specifically overlaps with perceptual processing around 160 ms after stimulus onset and from 300 ms onwards.
