The Genographic Project is a five-year effort to understand the human journey-where we came from and how we got to where we live today. This unprecedented effort will map humanity's genetic journey through the ages. If you choose to participate and add your data to the global research database, you'll help to delineate our common genetic tree, giving detailed shape to its many twigs and branches. Teachers can order Genographic Project Participation Kits at a special educator's discount, get free lesson plans related to the Genographic Project, and (coming soon) access other resources and discuss topics in forum boards.

CIESE sponsors and designs interdisciplinary projects that teachers throughout the world can use to enhance their curriculum through compelling use of the Internet.

A Punnett Square calculator, using the parental genotypes a student enters. Great for the ActivBoard.

The simplified mechanisms of drug action presented here are just a small part of the story. When drugs enter the body they elicit very complex effects in many different regions of the brain. Often they interact with many different types of neurotransmitters and may bind with a variety of receptor types in a variety of different locations. For example, THC in marijuana can bind with cannabinoid receptors located on the presynaptic and/or postsynaptic cell in a synapse.  Where applicable, this presentation primarily depicts how drugs interact with dopamine neurotransmitters because this website focuses on the brain's reward pathway. Mouse Party is designed to provide a small glimpse into the chemical interactions at the synaptic level that cause the drug user to feel 'high'.
