Outward currents through Kir2.1 channels play crucial roles in controlling the electrical properties of excitable cells, and such currents are subjected to voltage-dependent block by intracellular Mg(2+) and polyamines that bind to both high- and low-affinity sites on the channels. Under physiological conditions, high-affinity block is saturated and yet(More)
Outward currents through inward rectifier K+ channels (Kir) play a pivotal role in determining resting membrane potential and in controlling excitability in many cell types. Thus, the regulation of outward Kir current (IK1) is important for appropriate physiological functions. It is known that outward IK1 increases with increasing extracellular K+(More)
This study demonstrates that carbon nanotubes (CNTs) can be fabricated into probes directly, with which neural activity can be monitored and elicited not only extracellularly but also intracellularly. Two types of CNT probes have been made and examined with the escape neural circuit of crayfish, Procambarus clarkia. The CNT probes are demonstrated to have(More)
