About ia-1

Summary.

This data contains recordings from the grasshopper (Locusta migratoria) auditory receptor cell done by Ariel Rokem (now at UC Berkeley) when he was at the Institute for Theoretical Biology, Humbolt University, Berlin, in the Laboratory of Andreas Herz (now at the LMU, Munich). There are two sets of recordings. The first ('Data1') was collected in the Spring of 2003. Analysis of this data has been published in the following journal articles:

A. Rokem, S. Watzl, T. Gollisch, M. Stemmler, A.V.M. Herz and I. Samengo (2006). Spike-Timing Precision Underlies the Coding Efficiency of Auditory Receptor Neurons. Journal of Neurophysiology 95: 2541-2552.

The second set or recordings ('Data2') was collected in the summer of 2004. This data has not been previously published. Similar experimental methods were used in collecting both of these data sets.
