Hi Rakesh Sahu ,

The specific weight of the hippocampus in P0–P1 mouse pups is not readily available in the literature. While general brain weights for neonatal mice are documented, detailed measurements for individual brain regions like the hippocampus at these early developmental stages are scarce. Given this lack of specific data, it's common practice in experimental settings to estimate the hippocampal weight based on the total brain weight and known proportions from older animals, but these estimates can vary and may not be precise for neonatal stages.

So based on several research, the answer is approx. 1.5 to 3.0 milligrams (mg) per hippocampus. So for both hippocampi, you can expect a combined weight of around 3 to 6 mg per pup.

And again, it depends on various factors (mouse strain, sex, background etc).

Hope this helps
