Memory, Forgetfulness Help Hamsters Time Breeding

Date:
May 8, 2000

Johns Hopkins University
Summary:
A study shows that hamsters time their breeding by "remembering" whether days were longer or shorter in the recent past. The discovery provides a new experimental model for researchers seeking to undertstand human memory through studies of the simpler brains of animals.

A new study shows that the Siberian hamster, whose reproductive organs only become capable in spring and summer, temporarily retains information in its nervous system on the amount of daylight it experiences, and uses this information to make sure the reproductive organs become active at the right time of the year.
