Stimulation of inhibitory neurotransmitter receptors, such as gamma-aminobutyric acid type B (GABAB) receptors, activates G protein-gated inwardly rectifying K+ channels (GIRK) which, in turn, influence membrane excitability. Seizure activity has been reported in a Girk2 null mutant mouse lacking GIRK2 channels but showing normal cerebellar development as well as in the weaver mouse, which has ...

Currents through the inwardly rectifying K channel were studied under whole-cell clamp of collagenase-treated single ventricular cells of guinea-pigs. The inwardly rectifying K channel was fully activated by hyperpolarizing the membrane from the equilibrium potential for K+ (EK) by 30-40 mV. Following depolarization above EK, a decaying outward current was elicited. Prolongation of the hyperpol...

This paper is focused on a wireless energy harvesting system using a rectifying antenna (rectenna). The proposed device consists of a wideband cross-dipole antenna, a microwave low-pass filter and a doubling rectifying circuit using Shottcky diodes as rectifying elements. Previously, a few of wideband rectennas have been investigated at 1.7 to 2.5 GHz. The originality of this paper is on the ne...

Rectifying electrical synapses are commonplace, but surprisingly little is known about how rectification alters the dynamics of neuronal networks. In this study, we use computational models to investigate how rectifying electrical synapses change the behavior of a small neuronal network that exhibits complex rhythmic output patterns. We begin with an electrically coupled circuit of three oscill...

Interstitial cells of Cajal (ICC) undergo marked morphological changes on contraction of the musculature, making it essential to understand properties of mechanosensitive ion channels. The whole cell patch-clamp technique was used to identify and to characterize volume-activated Cl- currents in ICC cultured through the explant technique. Hypotonic solutions (approximately 210 mosM) activated an...

To solve the crosstalk problem when integration density of resistive random access memory (RRAM) devices increase, RRAM with self-rectifying function is required. Herein, Au/10 nm Al 2 O 3 /heavily doped p-type Si (p++-Si) structure was fabricated, and bipolar switching effect were investigated. A rectification 6.5 × 10 under ±5 V at low-resistive state (LRS) observed. The rectifying explained ...

Introduction B1 inhomogeneity in a human body increases as the strength of static magnetic field increases and the RF wavelength becomes smaller. Recently, various RF control methods have been developed to reduce B1 inhomogeneity. For example, some methods involve devices such as dielectric pads [1,2] or coupling coils [3,4], or techniques such as B1 shimming [5,6]. However, B1 inhomogeneity st...
