How our brain is working?

The human brain is the key regulator of the human body. All the voluntary and involuntary actions required by any human to live are controlled by the brain. From the functioning of the various organs of the body to the basic movements of the body parts, all are governed by the nerve impulses transmitted by the brain. 

However,  the  brain  also  manages  much  tougher  tasks  that  include  functions  related  to  learning, memorizing,  creating  ideas,  recall  incidents  and  many  more.  The different parts of the brain take command of these functions and enable humans to learn and interact. 

Some interesting fact about our brain

ØThe human brain has around 100 billion neurons equal to a computer with a 1,000,000,000,000 bit per second processor.

Ø  Brain consumes around 17% of the body’s energy in spite of being just 3 per cent of the body’s weight.

Ø  The feeling of fear is processed in the amygdale, a section of the brain also responsible for storing intense, personal, long-term memories.

Human Memory

Memory essentially is a function used to get, store, retain and retrieve when required the information. This functioning of the memory involves three major steps i.e. encoding, storage and retrieval. 

What affects the human memory?

The human memory can be affected by reasons like disease, injury, abnormal development or stress.  Living with problems related to the brain can be difficult as it may be difficult to complete daily activities stored in the memory.

Diseases like Dementia, Alzheimers disease, ADHD and ADD directly affect the brain cells causing them to deteriorate resulting in slow loss of memory.  In such a case the person forgets events happened a few  minutes  ago,  children  find  it  difficult  to  cope  with  school  and  adults  face  problems  at  work.  Disorders like Dementia and Alzheimers disease even affect the speech of the person as they forget commonly used words.

Stress also takes a toll on our retention ability. Stress distracts our course of concentration and makes it difficult to retrieve the memory.  As  per  a  research,  people  facing  too  much  of  stress  can  develop Alzhiemers disease in the later stage of life.

Our brain requires a constant supply of oxygen to keep functioning. If by any reason this does not happen, the brain will not store or recall memories. Many a times when oxygen is not provided to the brain it causes the particular area of the brain to be undeveloped. This affects the functioning of the memory.

There are lots of things we need to study about the human brain. My next article will provide how to improve our memory.
