“…A computational model of a VTA dopamine neuron was created in Genesis simulation software (Bower and Beeman, 2007). This model contains a fast sodium current (Na f ; Seutin and Engel, 2010;Tucker et al, 2012), a sodium leak current (Na L ), a delayed rectifying potassium current (Liu et al, 2012;Khaliq and Bean, unpublished data), an A-type potassium current I A , an I H current (Z. M. Khaliq, unpublished data;Migliore et al, 2008), and the calcium-activated potassium channels, SK and BK (Hirschberg et al, 1998;Maylie et al, 2004;Evans et al, 2013;Jaffe et al 2011). In addition, the model contains five calcium channels (T, R, N, L 1.2 , and L 1.3 ; Tuckwell, 2012;Evans et al, 2013; Table 1).…”
