Within the nervous system, the brain utilizes a variety of neurotransmitters to facilitate communication between neurons. One particular neurotransmitter, crucial for motor control and reward-related behaviors, is affected in neurological disorders such as Parkinson's disease and schizophrenia.

Which of the following neurotransmitters is primarily associated with these motor control issues and is known to be targeted by medications for treating schizophrenia?
