Change in R_in at a common membrane potential (−73 mV) in dorsal and ventral CA1 neurons after 50 μM Ba²⁺ wash-in experiments (related to Fig. 1)

Dorsal CA1	Baseline	50 μM Ba2+	Ventral CA1	Baseline	50 μM Ba2+
Rin, MΩ, at −73 mV	60.0 ± 3.5 (n = 6)	72.1 ± 4.2* (n = 6)	Rin, MΩ, at −73 mV	69.1 ± 5.1 (n = 7)	72.6 ± 7.2 (n = 7)

Statistically significant (

^*P < 0.05, paired t-test compared with baseline).
