noradrenaline necklace | sterling silver
The locus coeruleus is a brainstem nucleus smaller than a grain of rice. It contains roughly 50,000 neurons. Yet through noradrenaline, it modulates arousal, attention, vigilance, and threat response across the entire cortex. One tiny structure setting the brain's gain.
The Science Behind Noradrenaline
Noradrenaline (norepinephrine) is a catecholamine neurotransmitter synthesised from the amino acid tyrosine, produced almost exclusively by neurons in the locus coeruleus. Despite its small size, the LC projects axons to virtually every brain region and provides the primary noradrenergic input to the cortex, hippocampus, amygdala, and cerebellum. LC neurons fire tonically during waking, decrease during sleep, and burst in response to salient or novel stimuli. Noradrenaline modulates signal-to-noise in cortical circuits through alpha-2A and beta adrenergic receptors. Selective noradrenaline reuptake inhibitors (SNRIs) and atomoxetine treat depression, anxiety, and ADHD.
A Meaningful Gift for Science Lovers

FAQ
Would this resonate with someone studying stress and anxiety?
Absolutely. Noradrenaline is central to fight-or-flight responses and arousal. Clinicians working with anxiety disorders, cardiologists managing norepinephrine dosing, and psychologists interested in threat detection would all appreciate the specificity.
Why does the locus coeruleus matter so much in neuroscience?
The locus coeruleus is notable because a nucleus containing fewer than 50,000 neurons provides the primary noradrenergic input to virtually the entire forebrain. This small structure has outsized importance in wakefulness, attention, and the brain's response to stress. Damage to the LC is implicated in depression, ADHD, and Alzheimer's disease.
What are the size, material, and chain?
28 mm pendant in 925 sterling silver, nickel-free and hypoallergenic, high-polish finish. 45 cm sterling silver chain with a 5 cm extender and lobster clasp. Ships free worldwide via DHL Express in 1-5 business days. Comes in a ready-to-gift jewelry box with the 30-day “Love It or Return It” policy.
Is there a gold version?
Yes. Noradrenaline is available in 18K gold vermeil at the same 28 mm size. Many customers own both the silver and gold versions.
