Increased Hematopoietic Extracellular RNAs and Vesicles in the Lung during Allergic Airway Responses. [PDF]

, 2019
Extracellular RNAs (exRNAs) can be released by numerous cell types in vitro, are often protected within vesicles, and can modify recipient cell function. To determine how the composition and cellular sources of exRNAs and the extracellular vesicles (EVs)

Model of Low-pass Filtering of Local Field Potentials in Brain Tissue

, 2005
Local field potentials (LFPs) are routinely measured experimentally in brain tissue, and exhibit strong low-pass frequency filtering properties, with high frequencies (such as action potentials) being visible only at very short distances ($\approx$10 ...
