Neuronal Signaling encompasses the complex processes by which neurons communicate and transmit information throughout the nervous system. It involves the release, detection, and interpretation of chemical signals known as neurotransmitters, which traverse the synaptic cleft to bind with receptors on neighboring cells. This signaling underlies fundamental brain functions such as learning, memory, and cognition, and is a critical aspect of synaptic plasticity, where neural connections are strengthened or weakened in response to experience or environmental stimuli. By elucidating the mechanisms of neuronal signaling, researchers aim to better understand the neural basis of behavior and develop novel therapeutics for neurological disorders.
