Q10 (17�C27��C) for normalized data.

Shown are mean��SD. Values were extrapolated from a smaller temperature range, using linear or exponential fits (details in Materials and Methods and Table S1). 1: As defined by the onset time of the impulse response, K1. 2: Characteristic time-constant defined as: �� = (f3dB)?1. 3: Information transfer rate (Shannon's formula). 4: Information transfer rate (triple extrapolation method).
