Neurotransmitter Systems
Complex networks of chemical signaling molecules in the nervous system that regulate brain function, behavior, and consciousness through specialized receptor interactions and neural pathways.
Neurotransmitter Systems
Neurotransmitter systems form the chemical foundation of neural communication and play a crucial role in modulating Consciousness, Behavior, and Mental States. These systems consist of intricate networks of signaling molecules, receptors, and regulatory mechanisms that work in concert to maintain neural homeostasis and enable various states of consciousness.
Major Neurotransmitter Classes
Monoamines
- Serotonin - Regulates mood, sleep, and perception
- Dopamine - Controls reward, motivation, and motor function
- Norepinephrine - Manages attention and arousal
- Epinephrine - Coordinates stress response
Amino Acids
- GABA - Primary inhibitory neurotransmitter
- Glutamate - Main excitatory neurotransmitter
- Glycine - Spinal cord regulation
Other Categories
- Acetylcholine - Attention and arousal
- Neuropeptides - Complex behavioral responses
- Endocannabinoids - Retrograde signaling and mood regulation
