Dopamine Dynamics
Understanding how sympathomimetics like Adderall enhance dopamine and norepinephrine levels reveals the intricate workings of synapses, the crucial communication points between neurons. When neurotransmitters are released into the synaptic cleft, they bind to receptors on neighboring neurons, activating them and allowing signals to propagate. This process, while seemingly straightforward, involves complex machinery and transporters that manage neurotransmitter levels, highlighting the sophistication of our neural communication.In this clip

When you say "Neurons communicate at synapses, which are small gaps between them. When a neuron sends a signal, it releases neurotransmitters into this gap, affecting the activity of the next neuron (either exciting or inhibiting it)," is inhibition achieved through sending neurotransmitters that inhibit, or is it simply the lack of neurotransmitter transmission?
If I got it right, the neurochemical dynamics of dopamine are as follows: every activity releases dopamine from antecedent neurons into the synapses. Some activities release a small quantity of dopamine, while others release large quantities. There are dopamine receptors in those synapses, which activate according to the quantity of dopamine released by the antecedent neurons. If a lot of dopamine is released, there will be a lot of activation. However, the sensitivity, or the quantity of activation of the downstream neurons, is regulated by the sensitivity of the receptors. Did I summarize that correctly?
