Brain - Wikipedia
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing, and olfaction.

Brain Anatomy and How the Brain Works - Johns Hopkins Medicine
The brain is an important organ that controls thought, memory, emotion, touch, motor skills, vision, respiration, and every process that regulates your body.

Brain: Parts, Function, How It Works & Conditions
Your brain is a complex organ that regulates everything you do, like your senses, emotions, thoughts, memories, movement and behavior. It even controls body processes you don’t have to think about, like your breathing, body temperature and your heart rate.

Brain | Definition, Parts, Functions, & Facts | Britannica
The brain integrates sensory information and directs motor responses; in higher vertebrates it is also the center of learning. Learn more about the parts and functions of the brain in this article.

Human brain - Wikipedia
The brain can also be the site of tumours, both benign and malignant; these mostly originate from other sites in the body. The study of the anatomy of the brain is neuroanatomy, while the study of its function is neuroscience. Numerous techniques are used to study the brain.

Parts of the Brain and Their Functions - Science Notes and Projects
The brain is the central organ of the nervous system, responsible for thought, emotion, sensation, movement, and regulation of body functions. It has three main parts: cerebrum, cerebellum, and brainstem, each with distinct roles.

Brain Basics: Know Your Brain - National Institute of Neurological ...
This fact sheet is a basic introduction to the human brain. It can help you understand how the healthy brain works, how to keep your brain healthy, and what happens when the brain doesn't work like it should.

Parts of the Brain - Simply Psychology
The human brain is a complex organ, made up of several distinct parts, each responsible for different functions. The cerebrum, the largest part, is responsible for sensory interpretation, thought processing, and voluntary muscle activity.

Common Neurological Symptoms & Warning Signs

Persistent or Sudden Severe Headaches — Onset of unusually intense headaches, sudden thunderclap onset, or chronic pain accompanied by nausea and visual disruptions.
Numbness, Tingling, or Paresthesia — Loss of sensation, burning, or a "pins and needles" feeling in the extremities, often signaling peripheral neuropathy or nerve compression.
Focal Muscle Weakness or Paralysis — Sudden or progressive loss of muscle strength, facial drooping, or difficulty lifting objects, commonly associated with stroke or nerve disorders.
Seizures and Convulsions — Sudden, uncontrolled electrical disturbances in the brain leading to involuntary muscle spasms, loss of consciousness, or brief absence spells.
Vertigo, Dizziness, and Loss of Balance — Sensations of spinning, unsteady gait, or uncoordinated movement (ataxia), pointing toward vestibular or cerebellar dysfunction.
Cognitive Decline and Memory Impairment — Uncharacteristic confusion, difficulty retrieving words, disorientation, or short-term memory loss impacting daily functioning.
Visual Disturbances and Diplopia — Unexplained double vision, temporary loss of vision in one eye, or sudden blurred vision stemming from optic nerve issues or brain lesions.
Dysarthria and Speech Difficulties — Slurred speech, trouble articulating words, or difficulty comprehending spoken language due to motor speech pathway impairment.

Key Milestones in the History of Neurology

Edwin Smith Papyrus (c. 1600 BCE) — The earliest known medical document describing brain anatomy, cranial sutures, and meninges, detailing head trauma cases in ancient Egypt.
Hippocratic Corpus (c. 400 BCE) — Hippocrates challenged mystical beliefs by identifying the brain, rather than the heart, as the seat of human intelligence, sensation, and emotion.
Vesalius and De Humani Corporis Fabrica (1543) — Andreas Vesalius provided detailed anatomical drawings of the human nervous system, correcting centuries of Galenic anatomical errors.
Discovery of Cerebral Localization (1861) — Paul Broca demonstrated localized speech production functions in the frontal lobe through post-mortem studies of aphasic patients.
Establishment of the Neuron Doctrine (1891–1906) — Santiago Ramón y Cajal and Camillo Golgi revealed that the nervous system consists of discrete individual cells rather than a continuous net.
Invention of Electroencephalography (1924) — Hans Berger recorded the first human brain waves (EEG), revolutionizing epilepsy diagnosis and sleep cycle monitoring.
Development of Neuroimaging Techniques (1970s–1980s) — Godfrey Hounsfield developed Computed Tomography (CT) and Raymond Damadian pioneered MRI, transforming non-invasive brain visualization.
Discovery of Neuroplasticity (Late 20th Century) — Researchers demonstrated that the adult brain reorganizes neural pathways in response to learning, environmental changes, and injury recovery.

Current Neurology Research & Breakthroughs

Blood-Based Biomarkers for Early Alzheimer's Detection — Advances in blood tests tracking amyloid and tau levels allow for faster, non-invasive diagnosis before major cognitive decline occurs.
Adaptive Deep Brain Stimulation (aDBS) in Parkinson's — Closed-loop DBS systems now record real-time neural activity to dynamically adjust stimulation, significantly improving motor fluctuations.
Disease-Modifying Gene Therapies for Neurodegeneration — Novel viral vector therapies target genetic root causes to slow progression in rare conditions like Huntington's disease and ALS.
Precision Immunotherapies for Neuromuscular Disorders — Targeted monoclonal antibody treatments offer faster-acting, long-term disease management for autoimmune conditions like Myasthenia Gravis and CIDP.
Brain-Computer Interfaces (BCI) for Paralysis Recovery — High-density microelectrode arrays decode neural intent into real-time digital text and prosthetic movement for spinal cord injury patients.
Neuroinflammation and Microglial Modulation in Stroke — Investigational therapies focusing on microglial activation show promise in minimizing secondary brain injury following acute ischemic events.
Focused Ultrasound (FUS) Blood-Brain Barrier Opening — Non-invasive MRI-guided ultrasound temporarily opens the blood-brain barrier to deliver targeted chemotherapies directly into brain tumors.
Single-Cell RNA Sequencing in Epilepsy Therapeutics — Transcriptomic profiling identifies specific neuronal subpopulations causing drug-resistant seizures, opening pathways for targeted drug design.
