n. [生理] 超極化,過極化
Hyperpolarization and repolarization both describe increased electronegativity within the cell.
超極化及再極化都表明細胞内負電性的增強。
Most of these neurons showed a prominent slow after - hyperpolarization potential or current in response to depolarizing pulse.
大多數神經元在接受去極化刺激時出現明顯的慢後超極化電位或電流。
Recently, a family of hyperpolarization-activated and cyclic nucleotide-gated cation(HCN) channels comprising at least four members (HCN1-HCN4) has been cloned.
新近,一類被命名為超極化激活及環化核苷酸調控的陽離子(HCN)通道被克隆。
AIM: to research the reactivity of substantia gelatinosa neurons of the spinal dorsal horn of rats after hyperpolarization pulse stimulations and to reveal the intrinsic properties.
目的:研究脊髓背角膠質層神經元在超極化脈沖刺激下的細胞膜反應性,揭示神經元在超極化狀态下膜的基本性質。
The results showed that HCG depolarised membrane potential of toad oocytes, while tyrosine directly caused membrane, hyperpolarization, and inhibited the depolarization induced by HCG.
結果表明,HCG對卵母細胞膜電位有去極化作用,酪氨酸可以使膜電位呈現超極化反應,并能抑制HCG的去極化作用。
Hyperpolarization(超極化) 是生物學和神經科學中的術語,指細胞膜内外的電位差進一步增大的過程,表現為膜内電位比靜息狀态更負(或膜外更正)。以下是詳細解釋:
