NTUs, or Neurotransmitters, are chemical messengers that transmit signals across synapses, the tiny gaps between neurons. They play a crucial role in various physiological processes, including mood regulation, memory formation, and motor control. Neurotransmitters are classified into several categories based on their chemical structure and function. The most common types include:

Amines: These include serotonin, dopamine, and norepinephrine, which are involved in mood regulation, reward pathways, and attention.

Acetylcholine: This neurotransmitter is essential for muscle movement, memory, and learning.

GABA (Gamma-Aminobutyric Acid): GABA is the primary inhibitory neurotransmitter in the brain, helping to regulate anxiety and sleep.

Glutamate: This is the most abundant excitatory neurotransmitter in the brain, crucial for learning and memory.

Neurotransmitters are synthesized in the neuron's cell body, packaged into vesicles, and then released into the synaptic cleft upon stimulation. They then bind to receptors on the postsynaptic neuron, triggering a response. After use, neurotransmitters are either reabsorbed by the presynaptic neuron or broken down by enzymes, a process known as reuptake and degradation. Dysregulation of neurotransmitter systems is associated with various neurological and psychiatric disorders, making them a significant area of study in neuroscience and medicine.
