These include a relatively depolarized resting membrane potential, long-lasting action potential, high input resistance, prominent afterhyperpolarization (AHP) current, and hyperpolarization-activated cation current (Ih; Bolam et al. , 1984; Wilson et al. , 1990; Kawaguchi, 1993; Aosaki et al. , 1995; Bennett and Wilson, 1998; Bennett et al. , 2000; Zhou et al. , 2002).
