Neural circuits are networks of interconnected neurons that work together to process information in the brain and nervous system. These circuits enable various functions, such as movement, sensation, and decision-making. Each neuron communicates with others through synapses, allowing signals to be transmitted and processed efficiently. Different types of neural circuits are responsible for specific tasks. For example, reflex arcs are simple circuits that control automatic responses to stimuli, while more complex circuits are involved in higher cognitive functions, such as memory and learning. Understanding these circuits is essential for studying brain function and addressing neurological disorders.
