  • aFor each subject, the number of sample odors used in testing and the number of isolated CA1 pyramidal cells are reported. In addition, the number of neurons (and percentage of the total) that exhibited reliable temporal modulation in at least one odor trial type is shown for each of several types of analyses described in the text conducted separately.
