What are neuropeptides that affect a neuron's response to other neurotransmitters called?
Neuropeptides that affect a neuron's response to other neurotransmitters are called neuromodulators. They can enhance or inhibit the effects of neurotransmitters, thereby influencing neuronal excitability and synaptic transmission. By modulating the activity of neurotransmitters, neuromodulators play a crucial role in regulating various physiological processes, including pain perception, mood, and stress responses.

Is neurotransmitters transported by blood?
Neurotransmitters are not typically transported by blood; instead, they are released from neurons into the synaptic cleft, where they bind to receptors on neighboring neurons to transmit signals. While some neurotransmitters can affect the body when released into the bloodstream (like hormones), their primary function occurs locally within the nervous system. In the bloodstream, neurotransmitters can act more like hormones, but this is not their main mode of operation.
Does marijuana affect your neurones?
It is my understanding that marijuana slows down the connection between your neurotransmitters. This is the reason why it can be helpful against epileptic seizures as when these seizures occur, your neurons are being transmitted in uncontrolled rapid bursts (needs confirmation).
What would be the effect od a malfunctioning neurotransmitter?
A malfunctioning neurotransmitter can disrupt communication between neurons, leading to various neurological and psychological issues. For example, an imbalance in neurotransmitters like serotonin may contribute to mood disorders such as depression or anxiety. Additionally, issues with neurotransmitters like dopamine can affect motor control and are implicated in conditions like Parkinson's disease. Overall, such malfunctions can significantly impact behavior, cognition, and overall mental health.
A synapse consist of?
A synapse is the connection between two neurons. It consists of the synaptic cleft (the physical gap between one neuron's axon and the other's dendrite). Neurotransmitters cross the gap from the axon to the dendrite and affect whether the next neuron fires.
Does the number of neurons in a chain affect the signal speed?
Yes, the number of neurons in a chain can affect signal speed, but the relationship is not straightforward. While the speed of signal transmission along an individual neuron is primarily determined by factors like myelination and axon diameter, the overall processing time can increase with more neurons due to synaptic delays at each junction. Therefore, a longer chain of neurons can lead to slower overall signal propagation due to these additional processing times, despite individual neurons transmitting signals rapidly.
What are neurotransmitters that affect a neuron's response to other neurotransmitters called?
These are typically known as neuromodulators; they can either change the rate at which a neurotransmitter is released, or alter the response to a certain neurotransmitters.
Explain how neurotransmitters affect behavior?
Neurotransmitters are chemical messengers that transmit signals between neurons in the brain. They play a crucial role in regulating mood, emotions, and behavior. Imbalances in neurotransmitter levels can lead to various mental health disorders, such as depression, anxiety, and schizophrenia, impacting behavior and cognitive functions. By influencing communication among brain cells, neurotransmitters can modulate behavior by affecting processes like reward, motivation, and stress response.
How are the actions of sodium ions and neurotransmitters different?
Sodium ions are involved in generating action potentials in neurons by depolarizing the cell membrane, while neurotransmitters transmit signals between neurons by binding to receptors on the post-synaptic neuron. Sodium ions directly affect the electrical properties of the neuron, whereas neurotransmitters primarily modulate the chemical signaling between neurons.
Is neurotransmitters transported by blood?

What specific effects oes cafffine have on neurons?
The effect that caffeine has on neurons is to make them more sensitive to the effects of neurotransmitters. Caffeine lowers the threshold and makes the neurons more sensitive. This means it takes less of the neurotransmitter to affect another neuron.
What is the difference between a neuromodulator and a neurotransmitter?
A neuromodulator modifies or makes more or less efficient the synaptic action of a neurotransmitter. Whereas a neurotransmitters work as chemicals released from terminal vesicles into synaptic clefts to receptors depolarizing the next neuron and initiates an electrical charge.
If a persons brain had a low level of neurotransmitters how Would this affect the person?
Neurons would not be able to communicate across synapses. The different parts of the brain would not be able to communicate with each other as well.
What neurotransmitters does haldol affect?
Dopamine
Does marijuana affect your neurones?

How does caffeine affect the heart?
Well, caffeine (like most pyschoactive drugs) exerts its effect on us by altering the activity of some of our neurotransmitters. Neurotransmitters are the nervous system's way of conveying messages between neurons, and also to muscle tissue. Some neurotransmitters that caffeine is known to increase the activity of are norepinephrine, dopamine, and serotonin. The increase in norepinphrine is likely what causes the heart rate to increase, however each of these neurotransmitters has some stimulatory effects. Norepinephrine, however, is a powerfully stimulating neurotransmitter; it is associated with the 'fight or flight' response, which of course includes an increased heart rate. Caffeine can also cause ectopics (extra beats) in the heart if you have too much
Does exercise affect the production of neuropeptides?
Yes, exercise significantly influences the production of neuropeptides, which are small protein-like molecules that help transmit signals in the nervous system. Physical activity can enhance the release of various neuropeptides, such as endorphins, which are associated with pain relief and improved mood. Additionally, exercise has been shown to increase the levels of neuropeptides like brain-derived neurotrophic factor (BDNF), which supports neuroplasticity and overall brain health. These changes contribute to the positive effects of exercise on mental well-being and cognitive function.
Do chemotherapy drugs affect neurons?
some of the drugs can cross blood-brain barrier, so it can affect neurons too.
