In this study, we used EPO and GAL as short-term treatment to detect its effect on spatial memory tested by Morris water maze and its effect on proliferation in dentate gyrus
We found transplanted cells located only in the vicinity of the implant location near the hippocampal fissure and did not see graft cells in the dentate gyrus

Because of the reduced NMDA receptor levels , reported reduction in AMPA/NMDA ratio in NL1 KOs  and observed involvement of NL1 in the recruitment of NMDARs , it was hypothesized that NL1 might be involved in the regulation of long-term synaptic plasticity in the dentate gyrus
. Indeed, in vivo recordings demonstrated that NL1 KOs displayed diminished LTP , in keeping with the previously reported reduced excitation and LTP upon microRNA-mediated knockdown of NL1 in the dentate gyrus

Brain-derived neurotrophic factor and antidepressant drugs have different but coordinated effects on neuronal turnover, proliferation, and survival in the adult dentate gyrus

250 [micro]m area was randomly selected in CA1, CA3, and CA4 subregions as well as upper blade of dentate gyrus
from each of the selected 5 [micro] thick hippocampal section and unbiased quantification was done manually using ocular micrometer scale.

To further explore the possible underlying mechanism of the memory-enhancing effect of MME, the plasticity of the hippocampus was assessed via the assessment of the neuron density in CA1, CA2, CA3, and the dentate gyrus
of the hippocampus (Figure 3).
Furthermore, the presence of a persistent neurogenesis has recently been discovered in a specific region of the hippocampus, the dentate gyrus
; it involves the main neuronal type present there, the granule cells (for a review see ).
PV-positive interneurons were located in all layers of the dentate gyrus
. They were the most abundant in the hilus and less in the stratum moleculare, and only several cells were visible in the granule cell layer.
