Distinct forms of structural plasticity of adult-born interneuron spines in the mouse olfactory bulb induced by different odor learning paradigms.

The difference between the learner and control groups in terms of success rate was highly significant after block 13 (Fig. 1e , significant p values: 0.047, 0.043, 0.002, 0.032, 0.004, 0.003, <0.001 for blocks 9, 14, 17, 18, 20, 21, 22 respectively) Interestingly, the assessment of the spine density of adult-born GCs revealed that, unlike the simple discrimination task, the complex task led to an increase in spine density after training (control group: 0.73 ± 0.19 spines/μm, n = 97 cells from 4 mice vs. learner group: 0.84 ± 0.25 spines/μm, n = 104 cells from 4 mice, p = 0.001 with the Student t -test, Fig. 1f, g ).
