Experiment: Spiking reliability of ChR2-EYFP-positive dorsal raphe neurons in response to trains of light pulses at different frequencies, using an irradiance = ~5 mW/mm2. This zip file contains a list of 14 .csv file. Each .csv file contains a table of spike times (time of occurrence of spikes, in seconds) measured for one neuron in response to trains of light pulses at different frequencies (1, 2, 5, 10, 20 and 50 Hz). Each column represents one frequency (the frequency is indicated in the first row). Columns are filled with NAs at the end so that they have the same length. These data were used to generate the plots in Fig. 1L, Supp. Fig. S1B and Fig. S1E1 to E3
