The Power of Synapses: Understanding the Communication Between Neurons

TLDRSynapses, the tiny communication links between neurons, are 1000 times thinner than a piece of paper and more numerous than grains of sand on a beach. They are crucial for turning the structure of your nervous system into an actual system. This comprehensive summary explores the incredible characteristics and functions of synapses and how they allow us to learn, remember, and experience the world.

Key insights

⚡️Synapses are the meeting points between neurons that allow for communication and turning the structure of the nervous system into a functional system.

🧠The human brain contains around 100 billion neurons, with each neuron having thousands of synapses, resulting in trillions of synapses in total.

💻Synapses are like tiny computers, capable of running different programs simultaneously and adapting based on neuron firing patterns.

🔌Electrical synapses allow for fast communication between neurons, while chemical synapses provide more control and precision.

🌿Neurotransmitters play a crucial role in chemical synapses, determining whether the postsynaptic neuron gets excited or inhibited.
