Neurologists and neurosurgeons have an obligation to understand the structure, function and mind of the human brain. They also work with patients who have had brain injuries or who have been diagnosed with a disorder.
Understanding the Brain
Neuroscience is the study of the brain and how it works online neurologist. It focuses on how the brain creates thoughts and memories, and how the brain can react to certain stimuli or affect someone’s health or personality.
It is also the study of disorders that affect the brain. Those include stroke, Alzheimer’s disease, dementia and Parkinson’s disease.
There are many different types of neuroscience fields, including social, developmental and molecular. Researchers use these areas to better understand how the brain develops and how it works at different times in history.
The Structure of the Brain
The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision and all the processes that regulate our body.
The cerebrum, which makes up the largest part of the brain, is divided into two hemispheres (the left and right). They are connected by a thick bundle of nerve fibers called the corpus callosum.
Within each hemisphere, there are six areas or lobes that have different functions. The frontal lobe is associated with executive functions such as self-control, planning, reasoning and abstract thinking; the parietal lobe integrates sensory input; and the temporal lobe generates memories and emotions.
The cortical surface has folded appearance with hills and valleys and is made up of 16 billion neurons (the cerebellum has 70 billion). Beneath the cortex are long nerve fibers, called axons, that connect brain areas to each other — white latestforyouth matter.
The Function of the Brain
The brain interprets information from your five senses, gives meaning to what happens around you, and regulates automatic behavior such as breathing, heart rate and temperature. It also helps you remember events and actions, decide what’s important and control your emotions.
The human brain has three main parts: the cerebrum, the cerebellum and the brainstem (see Figure 1).
Your cerebral cortex lies on top of your brain, divided into two hemispheres that are joined at the bottom by a large groove called the interhemispheric fissure. The two hemispheres communicate with each other through a structure of white matter and nerve pathways called the corpus callosum.
Neurons are small cells that communicate with each other through a gap in their membrane, called a synapse. Each neuron has many arms called dendrites, which pick up messages from other nerve cells. The information is then sent to the cell body, which determines whether it should be passed on to other cells.
The Mind
The human brain is an incredible organ, it controls our body temperature, blood pressure, heart rate and breathing, it accepts a flood of information from the senses (seeing, hearing, smelling, tasting and touching) it allows us to think, dream and reason.
It also gives us the ability to experience emotions like fear, joy and anger.
Conclusion
There are billions of nerve cells arranged in patterns that coordinate thought, emotion, behavior, movement and sensation. This intricate architecture combines specialised functional processing in localised neural regions with global integration over longer distances between structures, which is what allows us to feel things, think and act.
