Basics and Scope of Neuroscience

Image
Neuroscience is the scientific study of the nervous system, particularly the brain, spinal cord, and peripheral nerves, encompassing their anatomy, physiology, functions, and pathologies. It is an interdisciplinary field that integrates knowledge from biology, psychology, physics, chemistry, computer science, and medicine to understand how the brain and nervous system influence behavior, cognition, emotion, and overall bodily function. The primary goal of neuroscience is to uncover how neurons and neural circuits produce mental and physical activities. From understanding how we perceive the world to uncovering the mechanisms of consciousness and memory, neuroscience explores the very foundation of what makes us human. Modern neuroscience emerged from centuries of curiosity about the brain, but it gained scientific rigor in the 19th and 20th centuries through advancements in neuroanatomy and electrophysiology. Today, it continues to grow rapidly, powered by new technologies and cross-...

Methods of Studying The Brain

Image
Understanding the brain—one of the most complex organs in the human body—requires a variety of research methods that examine its structure, function, chemistry, and activity. Over time, scientists have developed both invasive and non-invasive techniques to study the brain at multiple levels, from single neurons to entire brain systems. These methods allow researchers and clinicians to explore how the brain operates normally, how it develops, and what goes wrong in neurological and psychiatric disorders. The choice of method depends on the research question, the species being studied, and whether the study involves healthy individuals or patients. Below are the major methods used to study the brain, categorized by their primary approach. Neuroimaging Techniques   Neuroimaging provides non-invasive ways to visualize the structure and activity of the living brain. Structural imaging methods, such as Magnetic Resonance Imaging (MRI) and Computed Tomography (CT), are used to produce h...
