	Delayed onset, adapting
	Regular spiking(n = 12)	Fast spiking(n = 5)	Irregular spiking(n = 4)	Immediate onset, adapting(n = 6)	Strongly adapting(n = 5)
	group 1	group 2	group 3	group 4	group 5
Roundness soma	0.6±0.2	0.8±0.04	0.6±0.1	0.6±0.1	0.7±0.2
Aspect ratio soma	2.2±0.8	1.5±0.3	2.1±1.1	2.0±0.7	1.6±0.3
Verticality of dendrites	0.8±0.4	1.1±0.3	1.1±0.5	1.4±0.6	0.8±0.3
Orientation (degrees)*	59±31	61±27	37±37	24±25	71±19
Number of primary dendrites	4.1±1.2	4.2±1.6	5.5±2.6	4.4±0.9	4.2±0.4

*Tangential cells have an orientation close to 90 degrees; 0 degrees reflect radially oriented cells (similar to pyramidal cells).

No significant differences in morphological parameters between groups were detected (ANOVA). Values are given as mean ± standard error.
