Stability of tuning parameters across 2 weeks. (A) Left, distribution of tracked neurons pooled from all 4 animals between two sessions spanning 14 ± 2 days. 118 neurons that were responsive and well-tuned in Session1 were tracked in Session2. 16 (14%) of the tracked neurons were not responsive in Session2 (orange) and 12 (10%) were not well-fit by a Gaussian (yellow). 90 (76%) were responsive and well-fit by a Gaussian in both sessions (blue). Right, means across animals (bars) for the 1 and 2-week data sets. Offset circles, in the 1-week data set (hashed markings), 170 neurons were tuned in Session2, and of those neurons 92.7 ± 0.08% were tuned in Session1. In the 2-week data set 102 neurons were tuned in Session2, and of those neurons 89.8 ± 0.03% were tuned in Session1. Error bars are ± std. (B) Comparison of preferred orientation of neurons between sessions spanning 14 ± 2 days. The solid and dashed black lines are identical to Fig. 2C. Pearson’s correlation r = 0.964 (p = 1.88e-52). 15/90 neurons (light gray, pie plot) had a shift in the preferred orientation that was larger than 9 degrees. (C) Comparison of preferred spatial frequencies of neurons between sessions spanning 14 ± 2 days. The solid and dashed black lines are identical to Fig. 3A. 22/90 neurons (light gray, pie plot) had a shift in the preferred spatial frequency larger than 0.0125 cpd. Pearson’s correlation r = 0.922 (p = 5.64e-38).
