Fields are more frequently seen in control than in lesioned animals. This Table therefore includes the proportion of fields in comparison to the total number of units and in comparison to the number of fields in the baseline condition. The total number of complex spike cells that were recorded in both conditions (total) and the number of complex spike cells that had place fields in any of the conditions (fields) are indicated in parentheses. Identical, Fields were observed on the same maze arm in the baseline light condition and in darkness. Different, The peak activity of the field was located on different maze arms for each of the conditions. Unique, Fields were only observed in either the light or the dark condition. A χ2 test comparing the fields of the control and lesioned group in the three conditions (identical, different, unique) did not reveal a significant difference in responses across conditions (df = 2, χ2 = 1.79, p > 0.4).
