What is neurophenotyping?
Neurophenotyping simply means trying to identify how genes influence behaviour. A genotype is all of the genes that you have; a phenotype is which of those genes get expressed. I think of the genotype as being a blueprint to build something. The phenotype is the actual building that comes out. What we do, once that building gets produced, is we test it behaviourally. We ask how it behaves. Neurophenotyping is really about identifying the behavioural consequences of changes in genes and to see how different drugs might influence that relationship.
