Neurons and Brain Communication
Your brain contains billions of specialized cells called neurons that are the building blocks of your nervous system. When active, neurons generate electrical pulses and release chemical secretions to communicate with each other.
Neurons pass information at junctions called synapses - tiny gaps where the axon of one neuron connects with the dendrite of another. This process, called neurotransmission, is how your brain cells talk to each other through chemical and electrical signals.
Brain chemicals play crucial roles in neural communication. Hormones can excite neurons, inhibit them, or change their sensitivity to other signals. Neurotransmitters like acetylcholine help with attention, GABA provides pain relief, while others like dopamine, serotonin, and endorphins regulate everything from mood to movement.
Brain Buzz: Did you know that your brain uses the same amount of power as a 10-watt light bulb? All those neurons communicating through neurotransmitters are incredibly energy-efficient!
