In most cases, it is practically impossible to measure neurotransmitter levels in the brain or body at any given moment. Neurotransmitters regulate each other's release, and weak consistent imbalances in this mutual regulation were linked to temperament in healthy people.
Generally speaking, antidepressants help balance the neurotransmitters in the brain, so when you stop taking them, your system needs time to balance itself out again.
The vesicular monoamine transporter (VMAT) is a transport protein integrated into the membranes of synaptic vesicles of presynaptic neurons.It transports monoamine neurotransmitters – such as dopamine, serotonin, norepinephrine, epinephrine, and histamine – into the vesicles, which release the neurotransmitters into synapses, as chemical messages to postsynaptic neurons.
Analytes may include endogenous molecules (e.g. neurotransmitter, hormones, glucose, etc.) to assess their biochemical functions in the body, or exogenous compounds (e.g. pharmaceuticals) to determine their distribution within the body. The microdialysis technique requires the insertion of a small microdialysis catheter (also referred to as ...
Storage of the neurotransmitter in storage granules or vesicles in the axon terminal. Calcium enters the axon terminal during an action potential, causing release of the neurotransmitter into the synaptic cleft. After its release, the transmitter binds to and activates a receptor in the postsynaptic membrane. Deactivation of the neurotransmitter.
Wellbutrin prevents your brain from reabsorbing the neurotransmitters dopamine and norepinephrine. This can lessen symptoms of depression and anxiety. Because of this, Wellbutrin may also be used ...
A synapse during re-uptake. Note that some neurotransmitters are lost and not reabsorbed. Reuptake is the reabsorption of a neurotransmitter by a neurotransmitter transporter located along the plasma membrane of an axon terminal (i.e., the pre-synaptic neuron at a synapse) or glial cell after it has performed its function of transmitting a neural impulse.
One particular chemical, serotonin, is believed to be especially important in the regulation of our moods — which is why you may have heard it referred to as the “feel good” neurotransmitter.
