Transformative potential of conservation actions

Biodiversity and Conservation, 2022
AbstractTransformative change can help achieve the 2050 vision of biodiversity, but concrete ways to achieve it are only being discovered. To contribute to the understanding of the practical options for concrete action to foster, accelerate and maintain the transformative change, we assessed the leverage potential of existing conservation actions using

Consequences of converting graded to action potentials upon neural information coding and energy efficiency [PDF]

, 2014
Information is encoded in neural circuits using both graded and action potentials, converting between them within single neurons and successive processing layers. This conversion is accompanied by information loss and a drop in energy efficiency.

Large and fast human pyramidal neurons associate with intelligence

eLife, 2018
It is generally assumed that human intelligence relies on efficient processing by neurons in our brain. Although grey matter thickness and activity of temporal and frontal cortical areas correlate with IQ scores, no direct evidence exists that links ...

Modulation of Functional Connectivity Between Dopamine Neurons of the Rat Ventral Tegmental Area in vitro

Frontiers in Integrative Neuroscience, 2019
Micro Electrode Arrays were used to simultaneously record spontaneous extracellular action potentials from 10 to 30 dopamine neurons in acute brain slices from the lateral Ventral Tegmental Area (VTA) of the rat.

Similarities between action potentials and acoustic pulses in a van der Waals fluid [PDF]

, 2018
An action potential is typically described as a purely electrical change that propagates along the membrane of excitable cells. However, recent experiments have demonstrated that non-linear acoustic pulses that propagate along lipid interfaces and ...

Ventricular voltage‐gated ion channels: Detection, characteristics, mechanisms, and drug safety evaluation

Clinical and Translational Medicine, 2021
Cardiac voltage‐gated ion channels (VGICs) play critical roles in mediating cardiac electrophysiological signals, such as action potentials, to maintain normal heart excitability and contraction.

Modulation of neural cell membrane conductance by the herbal anxiolytic and antiepileptic drug aswal [PDF]

, 2000
To evaluate the effects of aswal on ionic fluxes and neuronal excitation, we performed extracellular and whole cell patch clamp recordings on CA1 pyramidal neurons of guinea pigs and Long-Evans rats.

Parametric analysis of the ionic concentrations effects in the behavior of the sinoatrial node

Revista Facultad de Ingeniería Universidad de Antioquia, 2013
A sensibility study on the effect of ionic concentrations in the behavior of the sinoatrial node was carried out. The study was based on the model proposed by H. Zhang, A. V. Holden and M.R. Boyett.
