Tuning In

In a previous post i made the analogy that our brain can be likened in many ways to a Smartphone.

 

In this post i would draw your attention to some similarities between our brain and a radio or television.

Radio TV

Our brain is a lump of structured and organised organic matter. It comprises of many, many billions of individual cells of different kinds, some of which build up the structure and help retain it’s basic form, some of which provide avenues for the supply of nutrients to those cells and to take away the wastes each cell generates; in this the brain is not much different to any other part of our bodies.

But some cells are very, very special (and specialised) indeed – they are the brain’s neurons. Cells which can generate and transmit electro-chemical signals and which form circuits and connections to other neuron cells, in some cases many thousands of other cells, directly. Although our brain is only about 1/50th of our total body mass and does not physically move anything directly, as do our muscles, it uses up approximately 20% of the energy our body generates, including while we ‘sleep’. Our brain cells produce electric currents and even generate their own electric field.

An instrument called an electro-encephalograph (EEG) is the device scientists and doctors use to measure these currents and fields within the brain by means of electrodes  placed on the outside of our head in fixed locations which can detect them and then display the resulting electrical activity onto a display device, such as a monitor screen. The monitor may show a dozen or more individual records as horizontal tracks of realtime variations in electric potential (the voltage difference over time) which are usually recording a specific frequency of electrical activity which is measured in units called hertz. This is the number of times per second a signal varies between higher and lower voltage in the electrode receivers. It is the electrical frequency of an area of electrical activity in the brain at any particular moment. (Something that might be important to remember is that in our homes in Australia, and other parts of the world, are encased in a wiring system that brings electricity for us to draw on any time we choose. When we draw some of that current for whatever device, ‘fridge, air-con, TV, computer, re-charger, lights, etc, etc, current flows and electric fields are formed. This electricity ‘cycles’ at 50-60 hertz and can have a total energy of several kilowatt/hours per day, for which we pay big bucks – those who don’t have solar panels or wind turbines anyway)

These individual tracks of an EEG show what is now commonly referred to as ‘brain waves’.

We believe we know what they are and how they are generated and we have given them a name, but we are by no means certain of what they do and how they do it. Basically, they are an indication of brain activity such as thinking or sensory reception from our sense organs, but they also indicate dreams, belief patterns and who knows what else? Could we be ‘seeing’ our consciousness in action?  They show our (very) limited awareness, of ‘all’ that is going on, both inside and outside of our bodies.

They are us as we dream, create,  write and speak, when we understand and analyse,  make decisions for ourselves, or even when we make ‘automatic’ decisions that take place seemingly without us doing anything, such as breathing at the rate we do or making our heart beat faster, or our face to flush if we feel embarrassed.

So think of all these many different waves as concerning certain thoughts or ‘trains’ of thought that may last for a brief second or might hold our attention for hours. There are many different and constantly changing waves but they also operate within certain sets of frequency ranges. We have so far identified 5-6 major groupings of waves and they are named after the Greek alphabet, for want of anything better.

They are the Alpha, Beta, Gamma, Delta and Theta waves. (Not sure what happened to Epsilon Zeta and Eta, the three letters in order between Delta and Theta?) Each one is identified with a specific type of our state of awareness. (See image).

brainwaves

 

The lower frequency range (Delta) is identified with deep sleep while the higher frequency one (Gamma) is identified as being in a state of heightened awareness/alertness. Gamma is the most recent set to be given it’s own classification. We spend most of our waking hours with our brains predominantly in the Beta range of  activity, however our brain makes waves of all kinds, all the time.

Except… what if we are seeing this picture from one of two ‘ends’?

What if, besides our brain seemingly ‘making’ these waves, in fact, our brains are receiving them?

Perhaps our incredibly intricate net of inter-connected neurons in our brains are specially formulated to pick up and amplify certain external frequencies of some form of wave radiation and the resultant activation of these neurons forms into the observed electrical wave activity/responses?

In this sense they would be behaving like a radio or TV antenna that receives and sends to an amplifier in the set the variations in radio wave frequency or amplitude ( FM or AM signals) so as to allow information (music/pictures/data) to be observed from a particular location other than the broadcast source.

Perhaps the received waves are of a different frequency to the ones when our brains are ‘awake’ or maybe they are of lesser amplitude (energy) which results in us largely not noticing the information they are presenting us with? Perhaps we better absorb them when our brains are in the Delta or Theta states. Or, they may be of a high frequency that we are mostly unfamiliar with in the times we are processing the information in our Beta state?

Remember the point about our electrical supply to the house having a frequency of 50-60 hertz? This is covering the range of brain wave frequencies that some have associated with ‘Compassionate meditation’ as practiced by Buddhist priests that is believed to allow us to receive higher levels of our conscious thought and helps achieve a blissful state of well-being and greater awareness. Could these frequencies be being ‘masked or prevented in our brains because of the power supply’s electrical field frequency?

Or maybe when we meditate (in the Alpha state) we can better notice and recall/hear the outside information and we can use it to our advantage somehow?

Perhaps this is a way we might ‘connect’ to some form of non-physical world/state of being?

Could it be an explanation of some ‘paranormal’ events? Spiritual ones even?

On another tack, what if in our train of thought we are most aware of as each second passes in our day is but one of several ‘tracks’ or radio stations that are all playing concurrently? When we tune a radio or TV to one channel we don’t suddenly stop broadcasting all the other stations/channels do we? We just focus and tune our set (attention) to one of many of hundreds of simultaneous broadcasts.

That being the case, then if we are presently paying attention to a track of  a remembered event in our past that might be making us sad could we learn to ‘switch channels’ and become aware of a track that anticipates a time of future happiness to compensate and lift our overall mood that has been building while on the ‘other channel’??

Remote

Could the key to  a permanent state of happiness or self-control be as simple as learning to turn a dial on your radio (or punch a button on your remote)??

 

Maybe there should be more research into the possibility? 🙂

Our Brain Is Like A… Smartphone!

Some people have compared a computer to a human brain, but if you take the time to think about it for a while you might see that our brain and a smartphone have quite a bit (more) in common with each other…

Nokia-7.1

Both are mostly thought to be single objects yet both are useless without ‘external’, seemingly unconnected, objects upon which they depend to perform their various different functions.

Both objects are actually comprised of many different sub-objects all wrapped up in a single package (with attachments) with very specific functions, many of which operate ‘automatically’ such that we do not have to consciously make an effort to use them. We may not even be aware* that some functions are being performed by the brain or by the smartphone.

Both objects have capacities that far exceed the average ‘user’s’ ability to utilise them all and to the fullest. Both can increase their memory storage capacity allocation.

Almost all users of either object largely try to work out what it can do by trial and error and rarely learn how to use it the way the manufacturer intended it should be used. They learn ‘how to get by’ and do not spend time studying what each specific function is and the best way to get the most out of it for all possible applications.

Both require a constant renewal of energy and will refuse to function effectively if their energy levels are below a certain level.

Both are subject to the occasional annoying breakdown and an expert may be required to be called upon to get it back into working order – this is usually expensive! Only one however, can be replaced and upgraded to a newer model in the event of a breakdown!

Both have almost unlimited memory storage these days although the smartphone recalls it’s memory far faster and more reliably.

People use both to tell them where they want to go although males are less inclined to ask for directions from their brain for this (or other people’s brains for that matter).

Both spend portions of their day when they are not being used (that we are aware of!!!) Both actually continue to function on some levels even if we think they are turned off!

Both can now recognise your own face, but only a smartphone can recognise your own thumbprint. Both can give you a very rough approximation of what the weather is going to be like today and for a few days into the future – neither are more than 90% accurate.

Both have to be programmed (taught) what to do by someone smarter than them although the brain is sometimes capable of learning by self-observation and very rarely by observing others (especially others’ mistakes!)  It will be a matter of a VERY short time indeed before our phones can do this better than our brains currently do.

This brings us to what has previously been a point of difference between the two objects… Consciousness!

Few people have a clear understanding of just what consciousness actually IS, other than to distinguish it from it’s opposite – unconsciousness.

I will suggest that a better term might be ‘Awareness*’. The brain is capable of developing something called ‘self-awareness’ – that it is an organic object located in a physical body comprised of squillions of individual cells and that it exists along a timeline from the moment of conception to the moment of death – and some would even say beyond that.

This awareness extends to the understanding that there also exist other objects such as ourselves that have their own version of self-awareness and that sometimes these things can have considerable difference to us while theoretically being largely constructed of the same things.

This awareness (consciousness) is not a continuous thing – it has regular ‘gaps’, periods of ‘un’ consciousness or non-awareness! Like a smartphone this is known as ‘sleep’ mode. (Or sometimes “switching off”). Once the brain comes out of sleep mode/being switched off or into a ‘stand-by’ state, it almost instantly returns to it’s previous level of awareness prior to being switched off – we do not have to retrain the brain, nor do we reprogram our smartphone once a day. The awareness is able to be added to during it’s ‘awake’ state and can acquire and retain new data to it’s accumulated total since becoming aware in the first instance and can use this to modify it’s behaviours. As mentioned in a previous paragraph, smartphones will soon possess this ability; it will learn from it’s own observations and will not require so much ‘updating’ from external sources/other people. It will teach itself certain things about it’s owner/operator and become more ‘user-friendly’, able to offer you better and easier choices in how to maintain your brain’s relationship with it.

So once this point is reached can we say that the smartphone has developed an ‘awareness’ or as we have compared it – consciousness.

Who says that human consciousness is the only kind that exists?
