What is synaptic communication?

Synaptic communication is the process by which neurons (nerve cells) interact with each other to transmit signals. Here are the key points explained by Andrew Huberman:

• Neurons and Synapses: Neurons communicate through structures called synapses, which are the small gaps between neurons 1 2. Neurons have an axon that ends in a region containing proteins that package neurotransmitters into vesicles.
• Neurotransmitter Release: These vesicles release neurotransmitters into the synaptic cleft (the space between neurons). This release can make the next neuron more or less likely to become electrically active.
• Electrical Activity: When neurotransmitters bind to receptors on the receiving neuron, they either excite the neuron, promoting electrical activity, or inhibit it, reducing electrical activity.

This process of synaptic communication is crucial for brain functions such as sleep, creativity, stress, and emotions. It involves complex machinery, but the main idea is that neurons use chemicals to relay electrical signals across synapses, enabling the brain and nervous system to function effectively 1 2.
