Is it bad to have thoughts racing in our mind?

‘Racing of thoughts’ is a typical phrase used by medical professionals like doctors especially those dealing with the mental health problems of people. It means that a lot of thoughts of various types are coming to and from in the brain very rapidly. The question is if it’s abnormal to have such thought race inside our brain.

The answer according to this author is ‘no’ unless the high speed flow of thoughts are disturbing our daily working life and social life miserably. Otherwise, it’s unlikely to be abnormal.

Here are 2 excerpts  from the web  to know it better-

Racing thoughts refers to the rapid thought patterns that often occur in manic, hypomanic, or mixed episodes. While racing thoughts are most commonly described in people with bipolar disorder and sleep apnea, they are also common with anxiety disorders, OCD, and other psychiatric disorders such as attention deficit hyperactivity disorder.

The phenomenon called racing thoughts is distinct from “hearing voices,” which is a symptom of schizophrenia, schizoaffective disorder, severe mania or other psychotic disorders. Racing thoughts can be a symptom of mania or hypomania, but unlike some other symptoms of these moods, they can also occur with depression or an anxiety disorder. Sometimes racing thoughts are accompanied by a pounding heart or pounding pulses, including drumming in the ears.

Various individuals may get various types of thoughts rushing in their brains depending upon their profession, social life, thought preferences etc. For example, a receptionist of a hotel who is on his way to his workplace may be preoccupied with thoughts of guests whom he is expecting to meet on reaching his office or the food he is going to have in the dinner or may be the gift which he should present to his girlfriend and so on. It is very hard to predict the spectrum of ideas that can run in a individual’s brain at one time.

I feel that racing of thoughts occur more at times when we are going through some type of stress or when there is no work to do with the active use of mind.

During morning hours while I am waiting at a traffic signal anxiously for the signal light to turn green, variety of thoughts start flowing in my brain like a storm and I try to pick some of those to sketch my posts, alike the one you are reading now.

Most authors in this world , I suppose, get various unique thoughts blooming in their brain at certain times of their life or day and they pluck some of those to write their story or article.

Therefore, it may be not always bad to have racing of thought inside our mind. May be it’s the dawn of an author’s next best writing!

What is love: a chemistry or biology?

It is not uncommon to find people referring love and sex as a ‘CHEMISTRY’ that plays between a couple, which finally leads to the emotional and physical bondage between them. But have you ever wondered if the word ‘CHEMISTRY’ is a misnomer with respect to love and sex.

When we talk about pure chemistry, technically it means either organic or inorganic chemistry. Inorganic chemistry primarily deals with various raw materials like iron, arsenic, cobalt etc. It’s less likely that inorganic chemistry has any major relation with love, may be organic chemistry might have some relations. Every sex related hormone have some sort of chemical structure, which have chemical bonds. So in this way we may relate love and sex with a branch of ‘CHEMISTRY’ called ‘organic chemistry’.

However, biology also seems to be important for love and sex. Sensations perceived via various sensory pathways (like visual, auditory, tactile (i.e. touch), olfactory (i.e. smell) etc.) are probably the first few sparks that are required to ignite the engine of love and passion in our brain which finally gears up the reproductive (genital) organs to complete the purpose of mating.

For the process of love making, two hormones known as testosterone and oestrogen have very important roles. Estrogen give females their lady contour by throwing more fat to specific sites of their body to squeeze out man’s passion. Similar is testosterone, takes care of the masculine features of male which makes women wild.

For rotating the wheel of love effectively the role of our nervous system can’t be undermined. Our nervous system can actually drive you crazy during the act of orgasm. Male depend solely on this system from erection to ejaculation.

Hypothalamus of our brain have a structure called septal nucleus which is responsible for our sexual urges. Besides that, we have a system in our brain called ‘limbic system’ which is too responsible for the sexual act.

One part of the brain, the Limbic System deals with and regulates emotions, memory, and sexual arousal. When it is not working properly, you will have feelings of depression and lethargy.

Therefore, it does not seem to be totally correct to define love and sex as a chemistry between two individuals, rather it’s more of raw hardcore BIOLOGY amalgamated with organic chemistry.

Before concluding I would love to leave this job into the reader’s hand to decide if love and sex is chemistry or biology. Whichever it may be, it should probably give us the eternal feeling of liveliness.

Which side of brain is involved in talking?

Our body does a complex group of actions to produce speech. Although, it might seem that we speak just because of movements of our lips, tongue and vocal cords, but much more is involved in production of speech. A complex set of nerves are required to fire and work in perfect harmony, to produce effective speech. This process of speech production starts from our brains, and like flow of river from hill top to sea, speech too flows down the nerves and produces vibration and movement of structures in oral cavity and throat which produces speech.

For long time people believed that speech is produced due to the function of left side of brain, which is probably not true any more. Recent findings show that speech production is due both sides of the brain.

Read an excerpt in this regard:

This new study directly examined the link between speech and brain activity. Patients in the study had specialized electrodes implanted directly inside and on the surface of the brain.

The researchers focused on parts of the brain used during speech. The participants were asked to repeat two “non-words” — “kig” and “pob.” Using non-words to trigger brain activity enabled the researchers to isolate speech from language.

The results showed that the participants used both sides of the brain for speech, according to the study published Jan. 15 in the journal Nature.

Effects of social networking on human brain

In today’s era there is hardly an individual who probably don’t know about face-book. For many people today, these social networking sites are just like some other essential commodities for life like oxygen or water. In present day society, may be in office or a bus stop people seem to be hauled on to these websites. But have you ever wondered why or what make people so crazy about these websites.

To answer it lets glue this fact with a little bit of human anatomy. According to a small new study a region in human brain called ‘nucleus accumbens’ is related to a person’s attraction to the such social networking pages. This particular region of our brain serve as reward center, when we are rewarded this center generally glows with happiness. After receiving positive responses on facebook this region becomes active. Those who get lot of positive feedback in face-book probably have more active nucleus accumbens. If you browse through most popular social networking websites you may find that they generally have ‘like’ or ‘favorite’ button only. Interestingly the ‘dislike’ type negative response buttons are disappearing from various social web pages and prime cause of such may be that these websites try to feed our reward centers only; because at the end of the day all that matters for a web hosting company is its ‘share prices’ and bucks and for that they need to please you. In real life too there are many individuals who are sensitive to or proud about how many likes they got for a particular facebook post, and invest significant amount of time to cherish.

These are probably called ‘tech-health’ days.

How ballet dancers spin so fast?

Three ballet dancers performing a grand jeté jump

Are you ever concerned about how ballet dancers can make so many spins in a go without feeling dizzy.

We feel dizzy primarily because of our inner ear. Our ear consists of 3 parts- outer, middle and inner. The inner ear is responsible for our balance and position senses. So when we spin our inner ear sends signal to our brain which makes us feel dizzy. But with practice this reflex can be suppressed.

New research in this matter evidences that, the dancers can spin without getting dizzy simply by doing a lot of practice. They practice this art for years and finally are able to suppress the dizzy feeling.

This new finding might help experts understand the dizziness problem better and may be able to help people suffering with chronic dizziness.

Coming back to the ballet dancers issue, the old proverb appears to remain true for them i.e. practice makes a man perfect.

Obesity and migraine

Cautious migraine sufferers do a lot to help their headaches. From avoiding of bright sunlight and chocolate to use of pain medications, almost all are tried but prevention is mostly like a never achievable type task. But what if, we had a list of things which we could have avoided to lessen the chance of a migraine attack. Confused? For example when a pregnant female learns smoking is bad for herself and her baby, she tries to stop the habit for her self and the fetus’s benefit. Similarly if concrete information about various things that can precipitate a migraine were available migraine sufferers could have combated their headache better.

Researchers in John Hopkins found irrespective of the type of migraine (an episodic migraine or a chronic migraine) it has significant link with obesity. It appears to be that obesity is the evil of all. Obese people are more prone to such headaches than non- obese individuals. Therefore a weight loss program may benefit to avoid those painful episodes and also shred some of the long term side effects of the pain medications by decreasing their requirements.

Note: an episodic migraine causes less than 14 headaches a month whereas a chronic migraine causes more than 15 a month.

Reading a felon’s mind

Can machine’s predict what is in a felon’s minds? Of course they can do so in movies and stories but probably not in real life. In real life till date we can’t predict accurately if a felon is going to re-participate in criminal activities. According to a recent research finding using fMRI (a type of MRI scan that studies brain activity by monitoring brain blood flow) we might now be able to predict if a convict is going to redo the criminal activities.

The felon’s with higher chance of repeating crime and getting arrested again showed lesser activity in brain regions related to decision-making and action. To achieve this findings fMRI scans were done on prisoner while they were subjected to some computer based tasks involving quick decision making and avoiding doing certain impulsive activities.

If you read the post  ‘Felt pain? Now you can view it too!‘ this is just a small addition to it. We talked there about what are fMRI’s are and how can they be used to visualize pain activity in brain. It appears fMRI’s are going to play important role in choosing which felons are to be followed in future to track down before they commit crime.

Overall it sounds like criminal mindedness can be revealed easily and police can do job more easily by focusing on the population more likely to do crime. But probably these are not tests what we can call reading machines of the mind of a man/woman.

However, human brain is not like a computer which run following the path of a software program, so how hard may a machine may try predicting what the person is going to do the machine can always fail since, human’s can decide new options, computers can’t. Forget about humans, even the best animal trainers fail to understand the animal’s nature and behavior (with whom they spend their whole life) and sometimes become the victim of the animal. Probably if such complete human brain reading devices are available apart from its benefits it may bring back the dark days of slave and master relation.
