In honor of Brain Awareness Week, here are five fun facts about the cerebrum you may not know.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. Your Brain Could Power a 25-Watt Light Bulb<\/h2>\n\n\n\n<p>The metaphorical light bulb over your head might be closer to the truth than you realize. The brain\u2019s billions of neurons consume <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC2816633\/\">20% of the body\u2019s energy<\/a> even when at rest, enough to power a small light bulb.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. The Brain Is Mostly Fat.<\/h2>\n\n\n\n<p>Move over neurotransmitters, lipids are the new hot molecule in brain research. The brain is <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/20329590\/\">approximately 60% fat<\/a>, and neuroscientists are just beginning to unravel how fatty acids play a role in brain performance and other critical functions. &nbsp;<\/p>\n\n\n\n<p>\u201cWhen most people think of molecules in the brain, they think of neurotransmitters,\u201d said WSU Elson S. Floyd College of Medicine molecular neuroscientist <a href=\"https:\/\/medicine.wsu.edu\/directory\/wsu-profile\/j.gerstner\/\">Jason Gerstner<\/a>, PhD. He studies fatty acid binding proteins found in astrocytes, star-shaped brain cells he found play an essential <a href=\"https:\/\/www.science.org\/doi\/full\/10.1126\/sciadv.1602663\">role in sleep regulation<\/a>. \u201cLipids are an underappreciated area of study, but modern neuroscience is now considering how cells in the brain operate with lipid signaling.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. The Brain Can Store as Much Information as 20,000 iPhones.<\/h2>\n\n\n\n<p>Your neural networks may be capable of storing up to <a href=\"https:\/\/www.scientificamerican.com\/article\/what-is-the-memory-capacity\/\">2.5&nbsp;petabytes<\/a> of information, equivalent to about 20,000 iPhones with 128 gigabytes of storage. Researchers note that brains <a href=\"https:\/\/aeon.co\/essays\/your-brain-does-not-process-information-and-it-is-not-a-computer\">are more flexible<\/a> than computers when it comes to storing memories and other information, but the rough metaphor captures the brain\u2019s extraordinary capacity.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">4. Brains Are Unique, like Fingerprints.<\/h2>\n\n\n\n<p>Every brain has a unique <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC8519575\/#:~:text=Therefore%2C%20an%20individual%27s%20functional%20brain,her%20or%20his%20connectivity%20profile.\">functional connectivity profile<\/a>, or pattern of how different areas of the brain connect. These profiles are distinct enough to identify an individual from a group solely using fMRI technology, imaging that measures blood flow to show activity in the brain.<\/p>\n\n\n\n<p>The nonmedical term \u201c<a href=\"https:\/\/journals.sagepub.com\/doi\/10.1177\/13623613241237871\">neurodiversity<\/a>\u201d was developed in the 1990s to describe how all brains develop differently. Activist Kassaine Asasumansu later coined \u201c<a href=\"https:\/\/www.psychologytoday.com\/us\/blog\/along-the-care-path\/202309\/the-term-neurodiversity-is-good-but-not-good-enough\">neurodivergent<\/a>\u201d to describe individuals whose brains work in an unexpected way, and the term has been embraced by people with autism spectrum disorder, ADHD, and other conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">5. Human Brains Have Shrunk Since the Last Ice Age.<\/h2>\n\n\n\n<p>Our brains have decreased in size by about 10% in the last 100,000 years, <a href=\"https:\/\/www.frontiersin.org\/journals\/ecology-and-evolution\/articles\/10.3389\/fevo.2023.1191274\/full\">research shows. <\/a>Anthropologists debate <a href=\"https:\/\/www.bbc.com\/future\/article\/20240517-the-human-brain-has-been-shrinking-and-no-one-quite-knows-why\">various possible explanations<\/a> for this shrinkage, from the invention of language enabling more symbolic and thus efficient thinking to a warming climate making smaller, quickly cooling brains more adaptive. Still, the average adult brain today <a href=\"https:\/\/www.hopkinsmedicine.org\/health\/conditions-and-diseases\/anatomy-of-the-brain\">weighs 3 pounds<\/a> and more than pulls its weight.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Learn more about the organ once described as \u201ca jet engine on an ancient horse cart\u201d this Brain Awareness Week.<\/p>\n","protected":false},"author":25158,"featured_media":33114,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[15],"tags":[107,29],"wsuwp_university_location":[],"wsuwp_university_org":[],"_links":{"self":[{"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/posts\/33113"}],"collection":[{"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/users\/25158"}],"replies":[{"embeddable":true,"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/comments?post=33113"}],"version-history":[{"count":4,"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/posts\/33113\/revisions"}],"predecessor-version":[{"id":33138,"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/posts\/33113\/revisions\/33138"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/media\/33114"}],"wp:attachment":[{"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/media?parent=33113"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/categories?post=33113"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/tags?post=33113"},{"taxonomy":"wsuwp_university_location","embeddable":true,"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/wsuwp_university_location?post=33113"},{"taxonomy":"wsuwp_university_org","embeddable":true,"href":"https:\/\/medicine.wsu.edu\/news\/wp-json\/wp\/v2\/wsuwp_university_org?post=33113"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
