Signalaing in Neuroscience

There are three types of signaling in neuroscience. Neurocrine signaling, also known as synaptic transmission, is when neurotransmitters are released by a presynaptic neuron into the synapse, and bind to the postsynaptic neuron. The presynaptic neuron fires an action potential for the neurotransmitters to be released, and to postsynaptic neuron depolarizes when the neurotransmitters bind. Endocrine signaling is when endocrine glands release hormones into the bloodstream. Hormones may have differing effects, and effect any cell type that expresses their receptor. This type of signaling results in slower, widespread effects. The third type of signaling is neuroendocrine signaling. This is when neurons integrate postsynaptic potentials, fire action potentials, and release hormones into the bloodstream.
