Differences in place field-width and information encoding along the hippocampal long axis.

(A) Place-field width defined as 20% of max firing rate and (B) spatial information in bits/spike are displayed using 25-50-75 percentile box plots with 10/90 percentile whiskers. Each region—anterior, middle, posterior—was computed separately. Significant differences are indicated with the starred horizontal black bars above the associated box plot pairs. (C) Population-vector autocorrelation analysis is shown for each of the 3 regions—anterior, middle, and posterior—ordered from left to right. Each point (i, j) in each matrix corresponds to the Pearson’s correlation coefficient between the activity vector constructed from all place-field firing rates at position i on the track with the activity vector of all place field firing rates at position j on the track. The color scale shown on the right applies to all 3 correlation matrices shown. The underlying data can be found at https://doi.org/10.5061/dryad.kk63d49.
