L-dopa acts as an antagonist for dopamine.

Single-celled protozoa were the first organisms to display a central nervous system.

Amphetamine and cocaine both prevent the reuptake of norepinephrine and dopamine.

The medulla is referred to as the "little brain" because it is extremely vital to basic life functions.

Alzheimer's disease is associated with a deterioration of serotonin-producing neurons.

The tectum and tegmentum are midbrain structures involved in the recognition of facial emotions.

Prozac acts as an antagonist for serotonin.

The parasympathetic nervous system is responsible for ejaculation in males.

The cerebral cortex, with its characteristic fissures, does not develop until the middle of pregnancy.

Twin studies have revealed that schizophrenia is determined completely by genes.

If shown the word "dog" in their left visual field, split-brain patients would have no problem drawing a picture of what they just saw with their left hand.

fMRI scans measure radioactive levels as a harmless radioactive substance is metabolized by active brain cells.

Only electrical stimulations that are above a threshold can initiate an action potential.
