Memory and the Brain

"Nothing is  more responsible for the good old days than a bad memory."

-Franklin P. Adams or Robert Benchley

A bad memory is the last thing we'd want. We scold ourselves for forgetting to buy an important ingredient after we've come back from the supermarket. We scold ourselves because we forget our wedding anniversary and hence got a severe reprimand and a scold in return. 

We scold ourselves because we forget our dental appointment and then got fined 200 Rs for a no-show. Unfortunately, even dentists act like policemen nowadays. One fines you for speeding, and the other penalizes you for not showing up.

That does not bode well for our financial future; nor does it bode well for the future of our minds.

What is memory?

It depends on what perspective we look at it. In psychology, memory is a human being's ability to store and remember bits and pieces of information and eventually to use such information when the need arises. 

Memory is used to fall under the field of philosophy, but in the early 20th century, it was integrated into cognitive psychology. Today, memory now property belongs to a branch of science that combines cognitive psychology and neuroscience. Thus, it is now under the realm of cognitive neuroscience. 

For our purposes, we will take first classification-by duration and explain it briefly before we deal with ways to improve our memory. Under memory by duration, we have three types:

  1. Sensory memory
  2. Short-term memory
  3. Long-term memory
According to Wikipedia, sensory memory corresponds to the first instant that a person or object is noticed. This observation sometimes moves into the sensory state, and qualities of short-term memory. 

Sensory memory means that the observation or perception lasts from milliseconds to seconds. Short-term memory, in turn, corresponds to memory that occurs from seconds to minutes.

Immediate interaction with things, objects, and persons constitutes our sensory memory as they are information produced by our five senses. Touching, smelling, or seeing are faculties that enable us to remember more easily.

Long-term memory is a memory that is stored and then retrieved after days and years. 

An example may help us understand this system of classification better: supposing someone gives us his number. We remember it for a few seconds maybe even up to a minute or two but soon forget it. This is short-term memory.

On the other hand, we remember certain phone numbers that we use frequently. our baby sitter's number, the pharmacist's, our husband's office-these numbers are stored in our long-term memory. 

In the next blogs, I will talk more about nutrition, exercises to keep our memory fast and agile. stay tuned!!!

The accountability mirror challenge by David Goggins

  The only way to improve yourself is to hold yourself accountable for the choices you made in your life.   This forces you to look at the things you have an influence on and take responsibility for. It frees you from any factors outside of your control. So how does this concept work and how can you apply it to your life? Like a lot of other concepts I discuss on this blog, this one is free of charge as well and very easy to start. This concept by David Goggins is another take on the affirmation exercise. Where you put post-its on the mirror of things that you are grateful for. How to start with David Goggins’s accountability mirror challenge? Stand in front of the mirror and look yourself in the eye for five minutes straight. What is going through your head? What do you think about the person you see in the mirror? Write those things down and make sure you discuss those with yourself later on. Now there are a lot of personal things you can hold yourself accountabl...

❤️⏺️ Keeping the love tank full ⏺️❤️

Love is the most important word in the English language and the most confusing. Both secular and religious thinker agree that love plays a central role in life. Love has a prominent role in thousands of books, songs, magazines and movies. We need love before we " fell in love" and we will need it as long as we live . I am convinced that keeping the emotional love tank full is as important to a marriage as maintaining the proper oil level is to an automobile. Running your relationship on empty "love tank" may cost you even more than trying to drive your car without oil. With all the help available from experts, why have so few couples found the secret to keeping love alive??  The answer to this question is people speak different love languages. Most of us grown up learning the language of our parents, siblings, which becomes our primary language. Later we learn additional languages, but with much more efforts. These becomes our secondary langu...

|| Misleading Descriptions Of a Woman’s Beauty ||

    Beauty is a mental concept Though a lady appears to be gentle and soft, yet she becomes rude, rough and distinctly masculine when she becomes angry. The feminine grace vanishes when she comes under the influence of wrath, indignation, fury and resentment. Have you ever seen women fighting in the streets? Women are more jealous than men. They have more Moha and passion also. They are eight times more passionate than men. Women have more power of endurance.  Maya havocs through the imagination of the mind. Woman is not beautiful, but the imagination is beautiful. Sugar is not sweet, but the imagination is sweet. Food is not palatable, but the imagination is palatable. Man is not weak, but the imagination is weak. Understand the nature of Maya and mind and become wise. Curb this imagination of the mind by Vichara or right thinking and rest in Brahman wherein there is neither imagination nor thought. Beauty and ugliness are false imaginations of the mind. ...
