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

Orexin enhances firing activities of neurons in neonatal rat sublaterodorsal tegmental nucleus

open access: yesDi-san junyi daxue xuebao, 2020
Objective To investigate the effect and underlying mechanism of orexin in modulating the firing activties of sublaterodorsal tegmental nucleus (SLD) neurons and its possible role in mediating rapid eye movement (REM) sleep regulation.

Numerical Investigation of T-Shaped Microfluidic Oscillator with Viscoelastic Fluid

open access: yesMicromachines, 2021
Oscillatory flow has many applications in micro-scaled devices. The methods of realizing microfluidic oscillators reported so far are typically based on the impinging-jet and Coanda effect, which usually require the flow Reynolds number to be at least at

The ionic mechanism of membrane potential oscillations and membrane resonance in striatal LTS interneurons [PDF]

open access: yesJournal of Neurophysiology, 2016
Striatal low-threshold spiking (LTS) interneurons spontaneously transition to a depolarized, oscillating state similar to that seen after sodium channels are blocked. In the depolarized state, whether spontaneous or induced by sodium channel blockade, the neurons express a 3- to 7-Hz oscillation and membrane impedance resonance in the same frequency ...

Bacterial GDGTs in Holocene sediments and catchment soils of a high Alpine lake: application of the MBT/CBT-paleothermometer [PDF]

open access: yes, 2011
A novel proxy for continental mean annual air temperature (MAAT) and soil pH, the MBT/CBT-paleothermometer, is based on the temperature (T) and pH-dependent distribution of specific bacterial membrane lipids (branched glycerol dialkyl glycerol ...

Mixed mode oscillations in mouse spinal motoneurons arise from a low excitability state [PDF]

open access: yes, 2011
We explain the mechanism that elicits the mixed mode oscillations (MMOs) and the subprimary firing range that we recently discovered in mouse spinal motoneurons.

Dynamics of sodium current mediated early afterdepolarizations

open access: yesHeliyon, 2017
Early afterdepolarizations (EADs) have been attributed to two primary mechanisms: 1) recovery from inactivation of the L-type calcium (Ca) channel and/or 2) spontaneous Ca release, which depolarizes the membrane potential through the electrogenic sodium ...

Auditory Long-Range Parvalbumin Cortico-Striatal Neurons

open access: yesFrontiers in Neural Circuits, 2020
Previous studies have shown that cortico-striatal pathways link auditory signals to action-selection and reward-learning behavior through excitatory projections.

A design principle of spindle oscillations in mammalian sleep

open access: yesiScience, 2022
Summary: Neural oscillations are mainly regulated by molecular mechanisms and network connectivity of neurons. Large-scale simulations of neuronal networks have driven the population-level understanding of neural oscillations.

Electrophysiological Features of Neurons in the Mesencephalic Trigeminal Nuclei

open access: yesNeurosignals, 2015
Mesencephalic trigeminal nucleus (Mes V) neurons represent an uncommon class of primary sensory neurons. Besides receiving somatosensory information, Mes V neurons are also involved in regulating multisensory information.
