The Impact of Neurotransmitters on Behavior

Study Notes

Neurotransmitters

Main function is to transmit signals across synapses between neurons, influencing various bodily functions and behaviors.
Serve as chemical messengers that facilitate communication in the nervous system.

Dopamine and the Body

Lack of dopamine can lead to motor control issues, mood swings, and cognitive impairments.
It plays a critical role in reward, motivation, and regulating mood.

Parkinson's Disease

Caused by the death of dopamine-producing brain cells in the substantia nigra region.
Symptoms include tremors, rigidity, bradykinesia (slow movement), and postural instability.
Affected individuals may exhibit mood disorders, including depression and anxiety.

Neurons and Message Transmission

Neurons transmit messages through electrical impulses and chemical signals, allowing communication across the nervous system.
They receive input from other neurons, process it, and send out responses.

Lack of Dopamine and Parkinson's Disease

Individuals with Parkinson's Disease have a deficiency of dopamine, leading to significant motor and non-motor symptoms.
Low dopamine levels can negatively affect mood, potentially leading to depression and reduced motivation.

Symptoms Not Associated with Parkinson's Disease

Certain symptoms like loss of appetite or visual hallucinations are not considered classic signs of Parkinson's Disease.

Impact of Low Dopamine on Mood

Low dopamine levels can result in feelings of apathy, lack of motivation, and contribute to the development of mood disorders.
