Differential expression of two-pore domain potassium channels in rat cerebellar granule neurons
(2014)
Two pore domain potassium (K2P) channels are mostly present in the central nervous system (CNS) where they play important roles in modulating neuronal excitability. K2P channels give rise to background K+ currents (IKSO) ...
Geographic variation in acoustic communication in anurans and its neuroethological implications
(2014)
Geographic variation of traits may represent the first step for evolutionary divergence potentially leading to speciation. Signals are behavioral traits of particular interest for the study of variation at a geographic ...
Genetic control of growth, biomass allocation, and survival under drought stress in Pinus radiata D. Don seedlings
