Description

Four (CAL1S and CAL1V), three (CAL2S and CAL2C) and four (e070528spont and e070528citronellal) Cockroach (Periplaneta americana) antennal lobe neurons (putative projection neurons) were recorded simultaneously and extracellularly during spontaneous activity and odor (vanilin and citronellal) responses from three different animals. The data sets contain the sorted spike trains of the neurons.

Format

CAL1S is a named list with 4 components ("neuron 1", "neuron 2", "neuron 3", "neuron 4"). Each component contains the spike train (ie, action potentials occurrence times) of one neuron recorded during 30 s of spontaneous activity. Times are expressed in seconds.

CAL1V is a named list with 4 components ("neuron 1", "neuron 2", "neuron 3", "neuron 4"). Each component is a named list with 20 components: "stim. 1", ..., "stim. 20". Each sub-list contains the spike train of one neuron during 1 stimulation (odor puff) with vanilin. Each acquisition was 10 s long. The command to the odor delivery valve was on between sec 4.49 and sec 4.99.

CAL2S is a named list with 3 components ("neuron 1", "neuron 2", "neuron 3"). Each component contains the spike train (ie, action potentials occurrence times) of one neuron recorded during 1 mn of spontaneous activity. Times are expressed in seconds.

CAL2C is a named list with 3 components ("neuron 1", "neuron 2", "neuron 3"). Each component is a named list with 20 components: "stim. 1", ..., "stim. 20". Each sub-list contains the spike train of one neuron during 1 stimulation (odor puff) with vanilin. Each acquisition was 14 s long. The command to the odor delivery valve was on between sec 5.87 and sec 6.37.

e070528spont is a named list of with 4 components ("neuron 1", "neuron 2", "neuron 3", "neuron 4"). Each component is a spikeTrain object (ie, action potentials occurrence times) of one neuron recorded during 60 s of spontaneous activity. Times are expressed in seconds.

e070528citronellal is a named list with 4 components ("neuron 1", "neuron 2", "neuron 3", "neuron 4"). Each component is a repeatedTrain object with 15 spikeTrain objects: "stim. 1", ..., "stim. 15". Each spikeTrain contains the spike train of one neuron during 1 stimulation (odor puff) with citronellal. Each acquisition was 13 s long. The command to the odor delivery valve was on between sec 6.14 and sec 6.64.

Details

The data were recorded from neighboring sites on a NeuroNexus (http://neuronexustech.com/) silicon probe. Sorting was done with SpikeOMatic with superposition resolution which can AND DOES lead to artifcats on cross-correlograms.
