Neuroscience has given us some of the most elegant structures in all of biology. The branching architecture of a neuron. The molecular geometry of dopamine. The folded complexity of the cerebral cortex. These are not just diagrams in a textbook. They are forms worth looking at, worth thinking about, and, it turns out, worth wearing.
This guide walks through the science behind each piece of neuroscience jewelry in our collection. If you are a neuroscientist, a psychology student, a psychiatrist, or someone who simply finds the brain fascinating, you will find something here that speaks to what you study, what you treat, or what you cannot stop reading about.
Neurotransmitter jewelry: the molecules that shape how you feel
Neurotransmitters are small molecules that carry signals between neurons. They are the chemical language of the nervous system. Each one has a distinct molecular structure, and each one plays a specific role in cognition, mood, movement, and perception.
Dopamine
Dopamine is a catecholamine neurotransmitter synthesized from tyrosine. It is central to the mesolimbic reward pathway, where it modulates motivation, reinforcement learning, and the anticipation of reward. But dopamine is not "the happiness molecule," despite what popular science often claims. It is more accurately described as the molecule of wanting. It drives you toward goals. It is the reason a deadline feels galvanizing and a notification feels urgent.
Outside the reward system, dopamine plays critical roles in motor control (its loss in the substantia nigra defines Parkinson's disease), working memory (via the prefrontal cortex), and endocrine regulation (as prolactin's primary inhibitor in the tuberoinfundibular pathway).
Our dopamine necklace renders the full molecular structure of dopamine. Available in sterling silver and 18k gold vermeil, in both horizontal and vertical orientations. Also available as a ring, studs, and bracelet.
Serotonin
Serotonin (5-hydroxytryptamine, or 5-HT) is an indolamine neurotransmitter derived from tryptophan. Roughly 90% of the body's serotonin is produced in the gut, not the brain, but the fraction that operates in the central nervous system has outsized influence on mood regulation, sleep-wake cycles, appetite, and social cognition.
The serotonergic system involves at least 14 receptor subtypes, which is part of why manipulating it pharmacologically is both powerful and unpredictable. SSRIs (selective serotonin reuptake inhibitors) remain first-line treatment for depression and anxiety, but the full picture of how serotonin shapes mood is still being written.
The serotonin necklace captures the complete molecular structure. Available in silver and gold vermeil. Also as a ring, studs, earring hoops, and bracelet.
Dopamine and serotonin together
In the brain, dopamine and serotonin are not opponents. They are collaborators with different emphases. Dopamine drives pursuit. Serotonin supports contentment. The interplay between them shapes everything from decision-making to impulse control, and disruptions in their balance are implicated in conditions ranging from depression to addiction.
Our dopamine-serotonin necklace interlocks both molecular structures into a single pendant. It is one of the most popular pieces in the collection, and for good reason: it represents something real about how the brain works. Available in silver, gold vermeil, mixed silver and gold, and as rings in silver and 14K solid gold.
GABA
Gamma-aminobutyric acid is the principal inhibitory neurotransmitter in the mammalian central nervous system. If the brain were an orchestra, GABA would be the conductor telling instruments when not to play. Without sufficient GABAergic tone, neural circuits fire excessively, which in its most extreme form manifests as seizures.
GABA acts primarily through two receptor classes: GABA-A (ionotropic, fast inhibition) and GABA-B (metabotropic, slow inhibition). Benzodiazepines, barbiturates, and general anesthetics all modulate GABA-A receptors, which tells you something about how central this molecule is to the pharmacology of sedation, anxiety, and anesthesia.

Oxytocin
Oxytocin is a nine-amino-acid peptide hormone produced in the hypothalamus and released by the posterior pituitary. It is often called "the love hormone" or "the bonding molecule," and for once, the popular label is not entirely wrong. Oxytocin facilitates social bonding, maternal behavior, pair bonding, and trust. It is released during physical touch, breastfeeding, and orgasm.
But oxytocin is also more complex than its reputation suggests. It can increase in-group favoritism and out-group suspicion. It plays a role in wound healing, inflammation, and cardiovascular function. The molecule does not simply make you feel warm. It makes social signals louder.
The oxytocin 3D necklace renders the peptide in three dimensions. Also available as a flat necklace, in gold vermeil, and as a ring.
Noradrenaline
Noradrenaline (norepinephrine) is the neurotransmitter of alertness and arousal. Released by the locus coeruleus, it sharpens attention, enhances memory consolidation under stress, and mobilizes the body's fight-or-flight response. It is chemically almost identical to adrenaline, differing by a single methyl group, but its primary domain is the brain rather than the periphery.
Dysregulation of noradrenergic signaling is implicated in PTSD, ADHD, and panic disorder. SNRIs (serotonin-norepinephrine reuptake inhibitors) target this system alongside serotonin.

Glutamate
Glutamate is the most abundant excitatory neurotransmitter in the vertebrate nervous system. It is involved in virtually every excitatory brain function: learning, memory, synaptic plasticity. The NMDA receptor, one of glutamate's primary targets, is the molecular gatekeeper of long-term potentiation, the cellular mechanism most closely associated with memory formation.
Excessive glutamate signaling causes excitotoxicity, a process implicated in stroke, traumatic brain injury, and neurodegenerative diseases. The balance between glutamate (excitation) and GABA (inhibition) is one of the most fundamental regulatory axes in the brain.

Orexin
Orexin (also called hypocretin) is a neuropeptide produced by a small cluster of neurons in the lateral hypothalamus. It regulates wakefulness, appetite, and arousal. The loss of orexin-producing neurons is the cause of narcolepsy type 1, one of the clearest examples of a single molecular deficit producing a specific neurological disorder.
Dual orexin receptor antagonists (DORAs) are a newer class of sleep medications that work by blocking orexin signaling, offering a mechanistically distinct approach to insomnia compared to traditional GABAergic drugs.

Neuron jewelry: the cell that started it all
The neuron is arguably the most recognizable cell in biology. Its morphology tells you its function: dendrites receive, the soma integrates, the axon transmits. Santiago Ramón y Cajal first drew neurons in the late 19th century, and his drawings remain some of the most beautiful images in the history of science. The branching form of a neuron is not decoration. It is information architecture.
Our collection includes several neuron types:
The neuron necklace is the classic multipolar neuron, the type most people picture when they think of a nerve cell. Available in silver and gold vermeil, and as earrings.
The DRG neuron necklace represents the dorsal root ganglion neuron, a pseudounipolar sensory neuron that relays pain, temperature, and touch from the periphery to the spinal cord. Its distinctive single-process morphology sets it apart from other neuron types. In silver and gold vermeil.
The spindle neuron necklace depicts the Von Economo neuron, a large bipolar neuron found in the anterior cingulate and frontoinsular cortex. These neurons are thought to play a role in social awareness, empathy, and rapid intuitive assessments. They are found only in a handful of species with complex social behavior: humans, great apes, elephants, and cetaceans. In silver and gold vermeil.
Brain jewelry: the whole organ
The human brain contains roughly 86 billion neurons and at least as many glial cells. It consumes about 20% of the body's energy despite being about 2% of its mass. It is the most complex object we know of in the universe, and we carry it around without thinking about it. Which, when you think about it, is the most brain thing possible.
The brain necklace shows the lateral view with the sulci and gyri of the cerebral cortex. In silver and gold vermeil. Also available as studs and cufflinks.
The sagittal brain necklace shows the midsagittal section: corpus callosum, thalamus, cerebellum, brainstem. The view you draw in neuroanatomy class and never forget. In silver and gold vermeil.
The limbic system necklace isolates the structures most associated with emotion and memory: amygdala, hippocampus, cingulate gyrus, and hypothalamus. In sterling silver.
Neuropharmacology jewelry: the molecules that change the brain
Some of the most important molecules in neuroscience are not made by the brain. They are made by chemists and given to patients. Each one tells a story about how we have learned to intervene in neural circuits.
Ketamine
Ketamine is an NMDA receptor antagonist originally developed as an anesthetic. Its rapid antidepressant effects, discovered serendipitously, have reshaped how we think about treating depression. Unlike SSRIs, which take weeks to work, ketamine can reduce suicidal ideation within hours. The mechanism appears to involve BDNF release and rapid synaptogenesis in the prefrontal cortex.
The ketamine necklace in gold vermeil. Also in silver, and as an interlocked ketamine-propofol necklace for anesthesiologists.
Fluoxetine
Fluoxetine (marketed as Prozac) was the first SSRI to achieve widespread clinical use. It selectively inhibits the serotonin transporter, increasing serotonin availability in the synaptic cleft. Its introduction in 1987 changed the landscape of psychiatric treatment and, for better or worse, shaped public understanding of depression as a chemical imbalance.

Psilocybin
Psilocybin is a tryptamine prodrug found in over 200 species of fungi. In the body, it is rapidly dephosphorylated to psilocin, a potent 5-HT2A receptor agonist. Clinical trials have shown promising results for treatment-resistant depression, end-of-life anxiety, and addiction. Its mechanism appears to involve a temporary increase in neural entropy, essentially loosening the brain's habitual patterns and allowing new connections to form.

Who wears neuroscience jewelry?
Neuroscientists, obviously. But also psychiatrists, neurologists, psychologists, neurosurgery residents, pharmacy students, neuroscience undergraduates, mental health advocates, and people who have a personal relationship with one of these molecules because it changed their life or the life of someone they love.
A serotonin necklace means something different to a pharmacologist than it does to someone who found the right SSRI after years of searching. Both meanings are real. That is what makes these pieces work.
