Correlations Between Neurogenesis and Behavior

Jason Snyder has compiled a very interesting list of 224 studies that have attempted to correlate neurogenesis with behavior while controlling for outside variables. Check out the full list here. Taking the author’s assertions at face value, it appears that 14/47 (29.8%) studies that correlated neurogenesis with depression / anxiety found a significant association, 0/12 studies that correlated neurogenesis with locomotion found a significant association, and  37/71 (52.1%) of studies that correlated neurogenesis with memory found a significant association, in some cases via reduced hippocampal dependence. So based on his cursory lit review the most consistent correlation between adult neurogenesis and behavior in adults can be found in differences in memory.
