Neuroanatomy — Simply Explained (Hub)
This hub page brings together short, patient-friendly neuroanatomy guides. Each page focuses on one core concept and uses clear wording and illustrations to help non-medical readers understand how the brain and nervous system are built and how they work. These explanations are intended to support patients who are learning about a specific neurological condition and want to better understand the structures involved.
If you are reading medical reports, imaging notes, or hospital discharge summaries, these guides can help you recognize key terms and follow the logic behind common neurological symptoms.
