Nanoscale adhesion and attachment oscillation under the geometric potential. Part 1: The formation mechanism of nanofiber membrane in the electrospinning

open access: yesResults in Physics, 2019
An electrospinning process is to produce nanofibers from a polymer solution by a high electrostatic force, which is used to eject jets from a Taylor cone formed on a nozzle.

Frequency dependence of CA3 spike phase response arising from h-current properties [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2013
The phase of firing of hippocampal neurons during theta oscillations encodes spatial information. Moreover, the spike phase response to synaptic inputs in individual cells depends on the expression of the hyperpolarisation-activated mixed cation current (

How DASPMI reveals mitochondrial membrane potential : fluorescence decay kinetics and steady-state anisotropy in living cells [PDF]

open access: yes, 2008
Spectroscopic responses of the potentiometric probe 2-(4-(dimethylamino)styryl)-1-methylpyridinium iodide (DASPMI) were investigated in living cells by means of a time- and space-correlated single photon counting technique.

Regulation of [Ca2+]i oscillations and mitochondrial activity by various calcium transporters in mouse oocytes

open access: yesReproductive Biology and Endocrinology, 2020
Oocyte activation inefficiency is one of the reasons for female infertility and Ca2+ functions play a critical role in the regulation of oocyte activation.

Theoretical foundations of the sound analogue membrane potential that underlies coincidence detection in the barn owl

open access: yesFrontiers in Computational Neuroscience, 2013
A wide variety of neurons encode temporal information via phase-locked spikes. In the avian auditory brainstem, neurons in the cochlear nucleus magnocellularis (NM) send phase-locked synaptic inputs to coincidence detector neurons in the nucleus ...

Dynamic response of model lipid membranes to ultrasonic radiation force. [PDF]

open access: yesPLoS ONE, 2013
Low-intensity ultrasound can modulate action potential firing in neurons in vitro and in vivo. It has been suggested that this effect is mediated by mechanical interactions of ultrasound with neural cell membranes.

Organelle calcium-derived voltage oscillations in pacemaker neurons drive the motor program for food-seeking behavior in Aplysia

open access: yeseLife, 2021
The expression of motivated behaviors depends on both external and internally arising neural stimuli, yet the intrinsic releasing mechanisms for such variably occurring behaviors remain elusive. In isolated nervous system preparations of Aplysia, we have
