They are heavier than typical earrings, but that isn't a problem.” (Molly S., from a review of the silver version)\u003c\/p\u003e\n\n\u003ch2 style=\"margin-top:2em;\"\u003eThe Most Expensive Organ You Own\u003c\/h2\u003e\n\u003cp\u003eThe human brain makes up about 2 percent of body weight, yet at rest it uses roughly a fifth of the body's energy. Most of it goes to signalling between neurons. After a neuron fires, it has to pump sodium and potassium ions back across its membrane to be ready for the next signal, and those pumps run on ATP. The brain keeps almost no fuel in reserve, so it depends on a steady supply of glucose and oxygen from the blood, minute by minute.\u003c\/p\u003e\n\n\u003ch2 style=\"margin-top:2em;\"\u003eExplore Related Neuroscience Jewelry\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/brain-studs\"\u003ebrain studs | silver\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/brain-18k-gold-plated\"\u003ebrain necklace | gold vermeil\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/sagittal-brain-18k-gold-plated\"\u003esagittal brain necklace | gold vermeil\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/dopamine-studs-gold-vermeil\"\u003edopamine studs | gold vermeil\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003csection class=\"product-faq\"\u003e\n\u003ch2 style=\"margin-top:2em;\"\u003eFAQ\u003c\/h2\u003e\n\n\u003ch3 style=\"margin-top:1.75em;\"\u003eHow big are they, and how do they close?\u003c\/h3\u003e\n\u003cp\u003eEach stud is 12 by 9 mm (about half an inch by a third), smaller than a 1-cent euro coin or a US dime. They sit on the earlobe and close with ear nuts on gold vermeil posts. 18K gold vermeil means 2.5 microns of 18K gold over solid sterling silver, nickel-free and hypoallergenic.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-top:1.75em;\"\u003eIs there a silver pair?\u003c\/h3\u003e\n\u003cp\u003eYes. The brain studs also come in sterling silver, at the same 12 by 9 mm. Choose the finish the recipient already wears: the design is the same in both.

For decades the round number was repeated without anyone having counted. In 2009 the Brazilian neuroscientist Suzana Herculano-Houzel and her team dissolved donated brains into a uniform liquid of cell nuclei, counted samples under the microscope and scaled up. They found roughly 86 billion neurons and about as many other cells. The same method, first published in 2005, has since been used to count the neurons of dozens of other species.\u003c\/p\u003e\n\u003c\/section\u003e\n","brand":"sciencejewelry1824","offers":[{"title":"Default Title","offer_id":57028498948482,"sku":"ER0066-GV","price":255.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1411\/4806\/files\/brain-studs-gold-vermeil.png?v=1794388509","url":"https:\/\/sciencejewelry1824.shop\/products\/brain-studs-gold-vermeil","provider":"sciencejewelry1824","version":"1.0","type":"link"}
