Identifying specific prefrontal neurons that contribute to autism-associated abnormalities in physiology and social behavior. [PDF]

open access: yes, 2017
Functional imaging and gene expression studies both implicate the medial prefrontal cortex (mPFC), particularly deep-layer projection neurons, as a potential locus for autism pathology.

The power of ionic movements in plants

open access: yesNew Phytologist, EarlyView.
Summary The movement of ion‐driven electrogenic events known as plant action potentials in the Venus flytrap Dionaea muscipula has first been recognized in Darwin's time. Besides electrophysiological techniques making use of current‐ and voltage‐recording electrodes, today an ever‐growing spectrum of tools has become available, that report online ...

Light and pH-induced Changes in Structure and Accessibility of Transmembrane Helix B and Its Immediate Environment in Channelrhodopsin-2 [PDF]

open access: yes, 2016
A variant of the cation channel channelrhodopsin-2 from Chlamydomonas reinhardtii (CrChR2) was selectively labeled at position Cys-79 at the end of the first cytoplasmic loop and the beginning of transmembrane helix B with the fluorescent dye ...

Models of cardiomyocyte–non‐myocyte electrical interactions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Cardiomyocyte–non‐myocyte (CM–NM) electrotonic coupling. Left: conceptual contact‐based interactions between CM and other NM via connexin (Cx) proteins. Three basic scenarios are proposed: (i) ‘zero‐sided coupling’ where there are no electrical connections between CM and NM, (ii) ‘single‐sided coupling’ where NM are connected to ...

Modeling Interference-Free Neuron Spikes with Optogenetic Stimulation [PDF]

open access: yes, 2019
This paper predicts the ability to externally control the firing times of a cortical neuron whose behavior follows the Izhikevich neuron model. The Izhikevich neuron model provides an efficient and biologically plausible method to track a cortical neuron'

Gap junctional and ephaptic coupling in cardiac electrical propagation: homocellular and heterocellular perspectives

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Intricate cellular electrical coupling networks in the heart. Various cell types couple the central cardiomyocyte through gap junctional contacts, with the exception of neurons. Whether ephaptic coupling (EpC) occurs in homocellular or heterocellular contexts beyond cardiomyocyte–cardiomyocyte interactions remains unclear ...

Reciprocal connectivity between mitral cells and external plexiform layer interneurons in the mouse olfactory bulb.

open access: yesFrontiers in Neural Circuits, 2013
Proper brain function relies on exquisite balance between excitation and inhibition, where inhibitory circuits play fundamental roles towards sculpting principle neuron output and information processing.

Neuromodulation: present and emerging methods. [PDF]

open access: yes, 2014
Neuromodulation has wide ranging potential applications in replacing impaired neural function (prosthetics), as a novel form of medical treatment (therapy), and as a tool for investigating neurons and neural function (research).

Optimal neuromuscular performance requires motor neuron phosphagen kinases

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Motor neuron (MN) terminals in fruit flies, mice and humans contain phosphagen kinases, a key enzyme in their energy storage and buffering system. Here we knocked down the primary phosphagen kinase in fruit fly larvae (arginine kinase 1 (ArgK1)) but were surprised to find that MN endurance was unaffected.
