neurotransmitterinä

Neurotransmitterinä is a term that appears to be a misspelling or a non-standard term. The widely recognized and correctly spelled term in neuroscience and biology is "neurotransmitter".

Neurotransmitters are chemical messengers that transmit signals across a chemical synapse, such as a neuromuscular junction, from one neuron (nerve cell) to another "target" neuron, muscle cell, or gland cell. For a substance to be classified as a neurotransmitter, it must meet a set of criteria. These include being synthesized in the neuron, being released from the presynaptic terminal upon stimulation, and producing a consistent response in the postsynaptic cell. Additionally, mechanisms for inactivation or removal from the synaptic cleft must exist.

The action of neurotransmitters is crucial for virtually all functions of the central and peripheral nervous systems. They are involved in everything from basic motor control and sensory perception to complex cognitive processes like learning, memory, mood, and emotions. Examples of common neurotransmitters include acetylcholine, dopamine, serotonin, norepinephrine, gamma-aminobutyric acid (GABA), and glutamate. Each neurotransmitter has specific receptors on the postsynaptic cell, and their binding triggers a particular cellular response, either excitatory (increasing the likelihood of the target cell firing an action potential) or inhibitory (decreasing the likelihood). Imbalances in neurotransmitter levels or function are implicated in a wide range of neurological and psychiatric disorders.
