Reilly Marian Tsanov 10.1371/journal.pbio.2002365.g003 https://plos.figshare.com/articles/figure/Navigation_preference_correlates_with_the_place_field_assembly_distribution_/5398960 <p>(A) Spatial distribution of the spikes (colored dots) from the reward loop cells (represented by different colors) recorded from 3 preference group animals and (B) from 3 nonpreference group animals. The straight red line denotes the weighted spatial population vector (SPV) between the southwest (SW) corner at 0° and the northeast (NE) corner at 90°. (C) Spatial distribution from all cells recorded from the same animals from the preference and (D) nonpreference groups, respectively. (E) Weighted SPV (left) for the preference group (<i>n</i> = 10 rats) and the nonpreference group (<i>n</i> = 10 rats), 2-tailed independent <i>t</i> test, <i>t</i>(18) = −6.116, ***<i>p</i> < 0.001; and averaged SPV (right), 2-tailed independent <i>t</i> test, <i>t</i>(18) = −7.283, ***<i>p</i> < 0.001, for reward loop cells. Error bars, mean ± SEM. (F) Weighted SPV (left), 2-tailed independent <i>t</i> test; <i>t</i>(18) = −5.048, ***<i>p</i> < 0.001; and averaged SPV (right), 2-tailed independent <i>t</i> test, <i>t</i>(18) = −5.208, **<i>p</i> = 0.006, for all cells. Error bars, mean ± SEM. (G) Comparison of the weighted SPV (left), <i>n</i> = 10, paired <i>t</i> test; <i>t</i>(9) = 5.043, ***<i>p</i> < 0.001; and averaged SPV (right), <i>n</i> = 10, paired <i>t</i> test; <i>t</i>(9) = 4.331, **<i>p</i> = 0.002 between the reward loop cells and all cells for the preference group. (H) Comparison of the weighted SPV (left), <i>n</i> = 10, paired <i>t</i> test; <i>t</i>(9) = −1.823, <i>p</i> = 0.102; and averaged SPV (right), <i>n</i> = 10, paired <i>t</i> test; <i>t</i>(9) = −1.740, <i>p</i> = 0.116 between the reward loop cells and all cells for the nonpreference group. (I) Correlation between the SW/NE passes ratio and the weighted SPV of the reward loop cells (left), <i>n</i> = 20 rats, Pearson’s <i>r</i> = −0.92, <i>p</i> < 0.001; and all cells (right), <i>n</i> = 20, Pearson’s <i>r</i> = −0.90, <i>p</i> < 0.001. (J) Correlation between the SW/NE passes ratio and the averaged SPV of the reward loop cells (left), <i>n</i> = 20, Pearson’s <i>r</i> = −0.91, <i>p</i> < 0.001; and all cells (right), <i>n</i> = 20, Pearson’s <i>r</i> = −0.75, <i>p</i> < 0.001. <i>Files dataset is available at Figshare public repository in Tsanov 2016 data / Continuous T-maze folder</i> <a href="https://figshare.com/s/b86a9a111353ba04bd32" target="_blank"><i>https</i>:<i>//figshare</i>.<i>com/s/b86a9a111353ba04bd32</i></a> <i>and Tsanov 2017 data / Continuous T-maze CA1 folder</i> <a href="https://figshare.com/s/5c5ba9b2811f3d7b7696" target="_blank"><i>https</i>:<i>//figshare</i>.<i>com/s/5c5ba9b2811f3d7b7696</i></a>.</p> 2017-09-12 17:25:55 ventral tegmental area remap parallels encode locations hippocampu context reward value support future adaptive behavior experience-dependent value reward context experience-dependent place field assembly distribution show place field memory formation tegmental dopaminergic activity place fields hippocampal neurons Hippocampal place cells place cells reward-driven navigation preference CA 1 region Optogenetic manipulation place field assembly distribution encodes population code
