Brain necklace | sterling silver Eighty-six billion neurons, organised into folds you can see at the surface, gyri rising, sulci dividing them, the architecture of thought you learn in your first neuroscience lecture. The pendant captures the cerebral cortex from a superior view, with both hemispheres divided by the longitudinal fissure and the gyri-sulci pattern rendered to scale in sterling silver. The Science Behind the Cerebral Cortex The folded surface visible on the pendant is the cerebral cortex, the outermost layer of the brain and the seat of higher cognition, perception, language, planning, decision-making. The folding is what allows roughly 1,500 cm² of cortical sheet to fit inside a skull only a third of that surface area. The deep grooves are sulci; the raised ridges between them are gyri. From above, the longitudinal fissure runs front to back as the deep central groove that divides the brain into its left and right hemispheres. The central sulcus arches across each hemisphere from the medial edge toward the lateral edge, separating the frontal lobe (anterior, with primary motor cortex along its posterior border in the precentral gyrus) from the parietal lobe (with primary somatosensory cortex in the postcentral gyrus immediately behind). The temporal lobes sit below the lateral surface and are not visible from this superior angle, but the cortical landmarks the pendant does show, gyri-sulci pattern, longitudinal fissure, central sulcus, frontal-parietal-occipital relationship, are the ones any neuroscientist will name on sight. At 22 mm the pendant is anatomically faithful: the major surface features read as themselves rather than as decoration. The Audience neuroscientists, neurologists, and neurosurgeons neuroscience and psychology students through their first systems neuroscience course doctors and medical researchers across specialties science educators and communicators who teach the cortex weekly anyone whose professional life or personal history runs through the nervous system Most often the everyday lab piece for working neuroscientists. Silver because gold reads as the gift version, and this is the one you wear to seminars, supervisions, and the SfN poster session.

Mostly working neuroscientists, neurologists, neurosurgeons, and the students and partners who cross paths with them every day. It also lands well with psychology and psychiatry, with science educators teaching neuroanatomy, and with people for whom the brain has become personal, through a diagnosis, a recovery, or a life shaped by someone else's. Strong as a gift for a neuroscience graduation, a board certification, or a milestone publication. Less of a generic medical-symbol piece than a stethoscope or caduceus. Recipients usually identify with the brain specifically, not medicine in general. What anatomy does the pendant show? A superior view of the cerebral cortex, looking down at both hemispheres from above. The longitudinal fissure runs front to back as the deep central groove dividing the hemispheres; the central sulcus arches across each hemisphere from the medial edge toward the lateral edge; the gyri-sulci pattern is rendered to scale. Lateral landmarks (lateral fissure, temporal lobe surface, Broca's and Wernicke's areas) sit below the visible surface and are not shown from this angle. It is the cortex specifically, not a midsagittal section, not a coronal slice, not a deep-brain rendering. Subcortical structures (basal ganglia, thalamus, hippocampus) are not visible on a surface view by definition. What size is the pendant and what does it ship with? The pendant is 22 mm in sterling silver (925), nickel-free and hypoallergenic, on a 45 cm sterling silver chain (1.8 mm width, lobster clasp) with a 5 cm extender, so it sits at the collarbone or a little below.

The anatomy is identical: same superior view, same 22 mm scale, same gyri-sulci pattern. Material is the only difference. The silver tends to be the everyday lab piece, worn to seminars, clinic, conferences, the daily run of neuroscience life. The gold reads as the more deliberate piece, more often picked as a milestone gift, a graduation marker, or a self-purchase after a long stretch of work. Both ship on a 45 cm chain in matching material.
