Dopamine primarily targets neurons in various regions of the brain, including the striatum, prefrontal cortex, and limbic system. These areas are involved in regulating movement, reward processing, mood, and cognitive functions. Dopamine acts on specific receptors, such as D1 and D2 subtypes, influencing diverse physiological and behavioral responses. Additionally, it can affect peripheral tissues, including the cardiovascular system and gastrointestinal tract.
What else can I help you with?
What is the effect of dopamine on the cells of the GPi?
Dopamine has an inhibitory effect on the cells of the globus pallidus internus (GPi). Increased dopamine levels lead to decreased firing of GPi neurons, which ultimately results in decreased inhibition of the thalamus and increased movement initiation and execution.
How does crsyal methamphetamine work at a cellular level?
Crystal methamphetamine acts by increasing the release of neurotransmitters like dopamine, norepinephrine, and serotonin in the brain. It binds to the dopamine transporter proteins on nerve cells, preventing the reuptake of dopamine and leading to increased levels of dopamine in the brain. This surge in dopamine results in the intense feelings of euphoria and increased energy associated with crystal methamphetamine use.
What Peripheral cells sensitive to the presence of hormones are called?
Target Cells
Does alcohol affect the dopamine gland?
Alcohol does not directly affect the dopamine gland. However, alcohol can indirectly impact dopamine levels in the brain by altering neurotransmitter release and uptake, which can influence the brain's reward system and contribute to the pleasurable effects of alcohol consumption.
What is dopamine secreted by?
Dopamine is primarily secreted by nerve cells in the brain, specifically by cells in the substantia nigra and ventral tegmental area. It plays a role in various brain functions such as regulating mood, motivation, and movement.
Which substances are secreted at the endings of nerve cells?
Neurotransmitters are the substances that are secreted at the endings of nerve cells to transmit signals to other nerve cells or target cells. These neurotransmitters can include molecules such as dopamine, serotonin, and acetylcholine.
Body cells that react to particular hormone are called?
target cells
What is the effect of dopamine on the cells of the GPi?
Dopamine has an inhibitory effect on the cells of the globus pallidus internus (GPi). Increased dopamine levels lead to decreased firing of GPi neurons, which ultimately results in decreased inhibition of the thalamus and increased movement initiation and execution.
How does alpha GPC affect dopamine levels in the brain?
Alpha GPC is a compound that can increase dopamine levels in the brain by promoting the production of dopamine and enhancing the release of dopamine from nerve cells. This can lead to improved cognitive function and mood regulation.
How does crsyal methamphetamine work at a cellular level?
Crystal methamphetamine acts by increasing the release of neurotransmitters like dopamine, norepinephrine, and serotonin in the brain. It binds to the dopamine transporter proteins on nerve cells, preventing the reuptake of dopamine and leading to increased levels of dopamine in the brain. This surge in dopamine results in the intense feelings of euphoria and increased energy associated with crystal methamphetamine use.
How are stem cells done?
Stem cells are what make the neurotransmitter dopamine. Also it is what helps control movement.
What is the difference between Target cells and non-target cells?
Target cells are cells that have specific receptors for a hormone or external signal, allowing them to respond to the signal. Non-target cells do not have receptors for the hormone or signal, so they do not respond to it. Target cells are the primary sites of action for hormones, while non-target cells are unaffected by the hormone.
What Peripheral cells sensitive to the presence of hormones are called?
Target Cells

What type of cells were researchers hoping to replace in patients with Parkinson's disease?
Dopamine Neurons
The tremors of Parkinson's disease result from the death of nerve cells that produce the neurotransmitter?
dopamine
