NEUROD1 and Cognitive impairment: The strong link between Neurod1 and neurogenesis combined with the marked deficit in the expression of hippocampal Neurod1 in this study further suggest a potential role of Neurod1 in mediating early life stress induced alterations in neurogenesis and associated cognitive deficits such as those recently reported (Suri et al., 2013; Naninck et al., 2015).
