Neurotransmitters are super important for how our brain connects and sends signals. They help our brain cells talk to each other, which affects how we learn and remember things.

1. Important Neurotransmitters:

   • Glutamate: This one helps make lasting connections stronger. It can boost the strength of these connections by up to 200%! That's a big jump and is essential for learning.
   • GABA: This neurotransmitter does the opposite. It helps decrease the strength of connections by about 30%. This is important for letting go of memories we might not need anymore.

2. How They Work:

   • When there's more calcium inside brain cells, it can strengthen these connections (this is called long-term potentiation, or LTP).
   • On the other hand, when GABA is active, it usually means less neurotransmitter is released, making connections weaker (this is known as long-term depression, or LTD).

These building blocks show how flexible our brain connections are, which is really important for learning and remembering things!
