The function of neurotransmitters in synaptic transmission is critical for communication between neurons. These chemicals are released from the presynaptic neuron into the synaptic cleft, where they bind to receptors on the postsynaptic neuron, leading to the initiation or inhibition of electrical signals. Neurotransmitters can modulate various functions, such as mood, cognition, and motor control, by influencing the excitability of neurons. The balance and regulation of neurotransmitters are essential for proper brain function, and imbalances can contribute to neurological disorders, highlighting their importance in neuroscience.
