Figure 3:
Schematic models depicting the ion currents present in each of 3 HVC model neurons based on the pharmacological identifications conducted in Daou et al (2013) as well as unpublished observations (particularly the expression of M-type K+ current in HVCRA neurons). Similar ion conductances across the 3 classes of HVC neurons are coded with the same colors. This shows indirectly the contributions of the various ion currents to shaping the firing properties of HVC neurons.
