The team did not study fly brains themselves, but rather read through the existing literature on fly olfaction and brain circuitry.

Now scientists know why: the stimuli overload their brain circuitry.

The brain circuitry responsible for processing rhythms and melodies appears to be one of the last regions to succumb to the physical damage associated with the disease.

Brain circuitry also evolved to favor monogamous attachment around the same time that our ancestors developed upright bipedal abilities.

It typically investigates at the level of neurons, neurotransmitters, brain circuitry and the basic biological processes that underlie normal and abnormal behavior.
