There is increasing interest in how the phase of local oscillatory activity within a brain area determines the long-range functional connectivity of that area. For example, increasing convergent evidence from a range of methodologies suggests that beta (20 Hz) oscillations may play a vital role in the function of the motor system [1-5]. The "communication through coherence" hypothesis posits th...

Perception routinely integrates inputs from different senses. Stimulus temporal proximity critically determines whether or not these inputs are bound together. Despite the temporal window of integration being a widely accepted notion, its neurophysiological substrate remains unclear. Many types of common audio-visual interactions occur within a time window of ∼100 ms. For example, in the sound-...

BACKGROUND The microtubule-dependent motility of endoplasmic reticulum (ER) tubules is fundamental to the structure and function of the ER. From in vitro assays, three mechanisms for ER tubule motility have arisen: the 'membrane sliding mechanism' in which ER tubules slide along microtubules using microtubule motor activity; the 'microtubule movement mechanism' in which ER attaches to moving mi...

Phase synchronization drives connectivity between neural oscillators, providing a flexible mechanism through which information can be effectively and selectively routed between task-relevant cortical areas. The ability to keep track of objects moving between the left and right visual hemifields, for example, requires the integration of information between the two cerebral hemispheres. Both anim...

Abstract Background The study aimed to establish a 68 Ga-FAPI-04 kinetic model in hepatic lesions, determine the potential role of parameters differentiation hepatocellular carcinoma (HCC) from non-HCC lesions. Material and methods Time activity curves (TACs) were extracted seven HCC lesions five obtained dynamic positron emission tomography (PET) scans eight patients. Three models applied TACs...
