(a) Pseudo-plateau burst trajectories are projected onto the ( c , V )-plane for g _K = 4 nS and g _BK = 4 nS, and different values of C _m . Key structures from the desingularized system are also shown. WED (pink curve) is the line tangent to the weak eigendirection of the folded node. (b) Magnification of panel (a) in the vicinity of the weak eigendirection and fold curve L⁺.
