Final answer:
The neurotransmitter released during learning processes like watching video lectures is dopamine, which increases cAMP levels in the brain, aiding in memory and learning.
Step-by-step explanation:
As you watched the video lectures for this section, your brain likely released lots of dopamine to help you learn this new information. Dopamine is a neurotransmitter that not only contributes to the pleasure and reward system, but also plays a critical role in the learning and memory process.
The binding of dopamine to its receptors in the brain increases the concentration of cyclic adenosine monophosphate (cAMP), an important secondary messenger involved in signal transduction. Regarding memory consolidation, repeated neuronal activity can increase neurotransmitter levels at synapses, enhancing synaptic connections and efficiency. Acetylcholine is another neurotransmitter that's strongly linked to memory and learning, and is known to be involved in the processes leading to memory consolidation as well.
