Brain Anatomy 101 is a clear, beginner-friendly guide to brain anatomy, designed to help you recognize the brain's main regions and understand how they contribute to thought, movement, and feeling. From the cerebral cortex and hippocampus to the cerebellum and brainstem, this page offers a simple tour of the brain's structure and its functions. By relating anatomy to everyday tasks—remembering a name, coordinating a movement, or interpreting a sound—you can start exploring today with confidence. Key regions: the frontal lobes guide planning and decision-making, the parietal lobes handle sensation, and the occipital lobes process vision, while the temporal lobes contribute to hearing and memory. The limbic system, including the hippocampus and amygdala, links emotion and memory, and the cerebellum coordinates balance and precise movements. The brainstem controls vital autonomic functions like breathing and heart rate. Understanding these parts is the core of brain anatomy and helps explain why stress can affect memory or how practice shapes skill through neuroplasticity. To extend this kind of structured understanding beyond the brain, InnerBuddies offers a modular Gut Health Operating System that maps the gut microbiome with similar clarity. The platform provides a Gut Microbiome Health Index—a score from 0 to 100 indicating gut health, built on an exclusive IP deal with EAFIT University in Colombia. It also displays Bacteria Abundances, comparing your levels to a healthy cohort for a top 40 bacteria list, and Bacteria Functions, categorized and labeled as positive or negative, so you can see where you stand on each functional category. Target Group Analysis dives into how the microbiome supports themes like Healthy Aging, Endurance Sport, and Skin & Hair Health, providing pathway-level scoring for relevant groups. And with Personalized Nutrition Advice, drawn from your 3-day food diaries and stool samples, plus Personalized Probiotics and Prebiotics guidance, InnerBuddies helps tailor recommendations to your unique gut microbiome. InnerBuddies also offers gut test solutions directly to consumers, so you can access these insights without a business intermediary. All of the B2B capabilities are also available directly to consumers who want a more business-like approach to their health data.
