Table 2. Characteristics of the neuron tuning curves.
The Full Width at Half Maximum (FWHM), the peak impulse rate of each family of neurons and the activity amplitude measured as the range of firing rates are shown. Numbers are given as median and standard deviation. The activity of Delta7 neurons in Drosophila is approximately even, hence the corresponding FWHM measurement is not meaningful and marked as ‘N/A’.
