Some Electrical Measurements of Motoneuron Parameters

Some electrical measurements of motoneuron parameters.

Electrical properties of the membrane of cat spinal motoneurons have been studied using pulses of current and sinusoidally varying currents applied with intracellular microelectrodes. Hyperpolarization of the motoneuron membrane produces time and voltage dependent changes in membrane resistance and E. M. F. The voltage transients produced by steps of current have been analyzed in order to deter...

Heritability parameters for some body measurements in Turkish Arabian foals

The aim of the present study was to estimate genetic parameters of body measurements in TurkishArabian foals. Records of wither height, front cannon circumference, heart girth, and body length were usedfor body measurements at birth, 6 months of age, 1-year-old and 2-year-old. Heritability of bodymeasurements of Turkish Arabian foals was estimated by using records of foals sired by stallions wh...

Determining Electrical and Heat Transfer Parameters Using Coupled Boundary Measurements

Let Ω ⊂ R, n ≥ 3, be a smooth bounded domain and consider a coupled system in Ω consisting of a conductivity equation ∇ · γ(x)∇u(t, x) = 0 and an anisotropic heat equation κ(x)∂tψ(t, x) = ∇ · (A(x)∇ψ(t, x)) + (γ∇u(t, x)) · ∇u(t, x), t ≥ 0. It is shown that the coefficients γ, κ and A = (ajk) are uniquely determined from the knowledge of the boundary map u|∂Ω 7→ ν ·A∇ψ|∂Ω, where ν is the unit ou...

Electrical measurements

In this module we will learn the most important principles of making electrical measurements in general, i.e., to obtain voltages and currents using the appropriate instruments and connections, and to understand and minimize sources of error. Furthermore, we will discuss selected electrical measurement methods used to obtain chemical and physical information of liquids, solids, and interfaces. ...
