The Complexity of the Brain: Exploring Neurons and Synapses

🧠Mapping the brain is a huge challenge due to the vast number of connections and the limited knowledge of their exact locations.

💡Neurons receive inputs from other cells in the brain through dendrites and transmit signals through axons.

🎯Synapses are the connections between neurons where information is transmitted.

🔬Electron microscopy allows for high-resolution imaging of the brain, enabling researchers to study its substructures.

🧩Understanding the brain's structure and function is crucial for building models and simulating brain activity.
