An Acoustoelectric Approach to Neuron Function

Acoustics, 2023
An acoustoelectric approach to neuron function is proposed that combines aspects of the widely accepted electrical-circuit-based Hodgkin–Huxley model for the generation and propagation of action potentials via electric polarization with mechanical models

Presynaptic actions of 4-Aminopyridine and γ-aminobutyric acid on rat sympathetic ganglia in vitro [PDF]

, 1980
Responses to bath-applications of 4-aminopyridine (4-AP) and -aminobutyric acid (GABA) were recorded intracellularly from neurones in the rat isolated superior cervical ganglion.

Position-dependent patterning of spontaneous action potentials in immature cochlear inner hair cells

Nature Neuroscience, 2011
Spontaneous action potential activity is crucial for mammalian sensory system development. In the auditory system, patterned firing activity has been observed in immature spiral ganglion and brain-stem neurons and is likely to depend on cochlear inner ...

Knowledge as Potential for Action [PDF]

European Journal of Pragmatism and American Philosophy, 2017
Can we conceive cogently of all knowledge – in particular, all knowledge of truths – as being knowledge-how? This paper provides reasons for thinking not only that is this possible, but that it is conceptually advantageous and suggestive. Those reasons include adaptations of, and responses to, some classic philosophical arguments and ideas, from ...

Population and species neighbor identity impact trait–trait relationships and plant performance

Population Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...

The Soliton and the Action Potential – Primary Elements Underlying Sentience

Frontiers in Physiology, 2018
At present the neurological basis of sentience is poorly understood and this problem is exacerbated by only a partial knowledge of how one of the primary elements of sentience, the action potential, actually works.

Human induced pluripotent stem cell-derived cardiomyocytes as an electrophysiological model: Opportunities and challenges—The Hamburg perspective

Frontiers in Physiology, 2023
Models based on human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) are proposed in almost any field of physiology and pharmacology. The development of human induced pluripotent stem cell-derived cardiomyocytes is expected to become a ...

Deforming tachyon kinks and tachyon potentials

, 2006
In this paper we investigate deformation of tachyon potentials and tachyon kink solutions. We consider the deformation of a DBI type action with gauge and tachyon fields living on D1-brane and D3-brane world-volume.

Charging Symmetries and Linearizing Potentials for Einstein-Maxwell Dilaton-Axion Theory [PDF]

, 1998
We derive a set of complex potentials which linearize the action of charging symmetries of the stationary Einstein-Maxwell dilaton-axion theory.Comment: 10 pages in ...

Dendritic cells steering antigen and leukocyte traffic in lymph nodes

FEBS Letters, EarlyView.
Dendritic cells are key players in the activation of T cells and their commitment to effector function. In this In a Nutshell Review, we will discuss how dendritic cells guide the trafficking of antigen and leukocytes in the lymph node, thus influencing T‐cell activation processes. Dendritic cells (DCs) play a central role in initiating and shaping the
