How female flies know when to say ‘yes’

7 octubre 2014

A fundamental question in neurobiology is how animals, including humans, make decisions. A new study reveals how fruit fly females make a very important decision: to either accept or reject male courtship. This decision appears to be generated by a very small number of excitatory neurons that use acetylcholine as their neurotransmitter located in three brain regions. This study provides the framework to understand how decisions are generated.
