A neurotransmitter and hormone involved in the body's 'fight-or-flight' response, affecting alertness, arousal, sleep-wake cycles, and attention.

What is norepinephrine?

The primary inhibitory neurotransmitter in the central nervous system, which reduces neuronal excitability and promotes calmness, helping to regulate anxiety and sleep.

Natural pain-relieving chemicals produced by the body, also associated with feelings of euphoria and well-being, often released during exercise or stress.

What are endorphins?

The primary excitatory neurotransmitter in the central nervous system, vital for learning, memory formation, and synaptic plasticity.

What is glutamate?

A neurotransmitter that plays a key role in muscle contraction, learning, memory, and attention, found in both the central and peripheral nervous systems.

What is acetylcholine?

neuropeptide that acts as a neurotransmitter and neuromodulator, primarily involved in transmitting pain signals from peripheral nociceptors to the central nervous system.
