A study on mice found that interventions increasing the creation of new neurons in the hippocampus (hippocampal neurogenesis) weaken memories of traumatic events and reduce PTSD symptoms.

Stationed within the meninges, squads of immune cells lie in wait, ready to unleash an inflammatory assault within the brain if needed. Holding these trigger-happy troops back during peacetime falls ...

and their colleagues wanted to search for evidence of neurogenesis in human brains and test a different technique compared with what had been used in the past. The team collected postmortem and ...

In adolescent male mice, hippocampal neurogenesis regulates dominance behavior independently of anxiety, revealing a novel function for this cellular process. Natural variations in hippocampal ...

Within the irradiated hippocampus, precursor proliferation is reduced by 62% and neuro-genesis is almost entirely ablated. The absence of neurogenesis could be due to the dysfunction and/or loss ...

but the animals lacking hippocampal neurogenesis kept drinking. When the team ran the experiment without the water bottle, both sets of rats looked around right away to figure out where the sound was ...

Research has also shown that environmental enrichment enhances neurogenesis in the dentate gyrus, a part of the hippocampus in which the birth of new neurons and glia continues in adulthood.

Regular aerobic exercises like walking or swimming can increase the size of your hippocampus by up to 2%. This growth ...
