Figure 4. Changes of membrane input resistances, action potential thresholds, and resting membrane potentials in not-for-cold-sensing neurons at the cold temperature of 15°C.
A) Right panel, summary data of membrane input resistances at 24°C (open bars) and 15°C (closed bars) for each cell type. Left panel, summary data of input resistance at 24°C (open bars) for cells displaying multiple AP firing pattern (n = 65) and phasic firing pattern (n = 44), and input resistance at 15°C (closed bars) for cells displaying multiple firing pattern (n = 70) and phasic firing pattern (n = 39). The neurons of each firing pattern are pooled together from all subtypes in left panel. B) Summary data of AP thresholds at 24°C (open bars) and 15°C (closed bars) for each cell type. C) Summary data of resting membrane potentials (RMP) at 24°C (open bars) and 15°C (closed bars) for each cell type. Sample sizes: type 1a cells, n = 36; type 1b cells, n = 15; type 1c cell, n = 25; type 2a cells, n = 8; type 2b cells, n = 15; type 3a cells, n = 5; type 3b cells, n = 5. Data represent Mean ± SEM, * P < 0.05, *** P < 0.001; ns, no significant difference.
