Fig 7. Three physiological parameters produce good separation of the two main pyramidal neuron subtypes.
(A) Representative membrane potential responses to somatic current injections for three pyramidal neurons from each subtype (green/A and magenta/B). Input currents ranged from 50 to 70 pA. (B) Partial separation between the two main pyramidal neuron subtypes is observed in a plot of clustered data points (green/A and magenta/B) within the space spanned by the resting membrane potential (Vrest), the input resistance (IR), and the action potential frequency adaptation ratio (AP FAR).
