Neurons in the Endbrain of Numerically Naive Crows Spontaneously Encode Visual Numerosity  Lysann Wagener, Maria Loconsole, Helen M.

Figure 1 Task Protocol and Example Stimuli (A) The crows performed a delayed match-to-sample task in which they discriminated the color of dot arrays. A trial was initiated by moving the head into a light barrier in front of the screen and keeping it in this position. After a short pre-sample phase, a sample stimulus (colored-dot array) was presented for 800 ms, followed by a delay of 1,000 ms. In the subsequent test phase, a match stimulus (same color as the sample) was shown as test 1 in 50% of the trials, in the other half a non-match stimulus (different color as the sample) was presented first and followed by a match stimulus. The crow was rewarded for responding by moving its head out of the light barrier whenever the color of a test stimulus matched the color of the sample. (B) Example stimulus displays. Each of the five colors was presented in five different numerosities and two different stimulus sets (standard and control).

Figure 2 Behavioral Performance of Both Crows (A) Performance in the color discrimination task during recording sessions (crow T: n = 50; crow V: n = 43). Chance level is 50%. Error bars indicate SEM across the sessions. (B) Performance in the numerosity-discrimination task in the generalization test sessions (crow T: n = 283 trials; crow V: n = 270 trials). Chance level is 50%. Current Biology 2018 28, 1090-1094.e4DOI: (10.1016/j.cub.2018.02.023) Copyright © 2018 Elsevier Ltd Terms and Conditions

Figure 3 Brain Area and Neuronal Responses (A) Lateral view of a crow brain with the nidopallium caudolaterale (NCL) located inside the telencephalon color coded. Cb, cerebellum; OT, optic tectum. (B–D) Neuronal responses of exemplary neurons to the number of presented dots in the sample stimulus. The neurons were selective to numerosity 1 (A), 2 (B), and 5 (C). Top: Dot-raster histograms with each line indicating one trial and each dot representing an action potential. Activity is separated for standard and control conditions. Bottom: Corresponding spike-density functions, representing the time course of the average response to each numerosity (smoothed by a 150 ms Gauss kernel). Colors of dot-raster histograms and spike-density functions correspond to the numerosity of the sample stimulus. Vertical line at 0 ms indicates onset of the sample that was shown for 800 ms. Tuning function insets indicate the average firing rate to numerosity in the standard (std) and control (cntr) condition. Error bars represent SEM. See also Tables S1 and S2.

Figure 4 Average Tuning Properties (A) Frequency distribution of the neurons’ preferred numerosities. (B) Average tuning functions for neurons preferring the same numerosity. (C) Average normalized activity of all numerosity-selective neurons as a function of numerical distance from the preferred numerosity. Error bars indicate SEM.
