Neuronal signaling is the process by which neurons communicate with each other using electrical and chemical signals. Neurons are the basic building blocks of the central nervous system, and their ability to send and receive signals is essential for various brain functions, including cognition, memory, and movement. Neuronal signaling involves the transmission of signals along the length of a neuron and the release of neurotransmitters at the synapse, where two neurons meet. This complex process is tightly regulated and involves a variety of proteins, ion channels, and signaling molecules. Understanding neuronal signaling is crucial for gaining insights into normal brain function and the mechanisms underlying neurological disorders such as Alzheimer's disease, Parkinson's disease, and epilepsy.
