That depends on what type of information is 'thought about'. For example, some people 'think' in images, others think in 'data' or the written word. Each uses different areas of the brain.
No, the brain is not actively "awake" in the same way when we are asleep. However, the brain is still processing information and carrying out essential functions during sleep, such as consolidating memories and regulating bodily functions.
Although the question appears to make sense, the questioner has not defined what they mean by 'a thought'. And does s/he mean 'conscious thoughts', 'unconscious thoughts', or both? Mind you, with our current level of technology, and knowledge about how the brain works, it is in any case more or less impossible to give a definitive answer. So here's "an" answer, which may or may not be relevant, depending on what the person asking the question had in mind: For example, about 10Mbits of information are transmitted along each optic nerve PER SECOND. But is transmission speed the same thing as processing speed? Research reported on the MIT website indicates that under certain circumstances, one measure of processing speed has registered as few as 60 bits per second. And on the other hand, the researcher has made it plain that he was not testing for the maximum processing speed across a variety of tasks. So we cannot assume that his results were representative of brain processing in general. An estimate on the University of Alberta website suggests that the average "clock speed" of neurons in the brain is a mere 200 firings per second - compare that with the clock speed of even a cheap desktop computer in 2010. But that's only part of the story, because the brain of an average healthy human being includes around 100 billion neurons, all connected to something like 1000 (or more) other neurons. 100 billion neurons all firing around 200 times per second gives a capacity of 20 million billion firings per second. Having said that, brain scans show only specific areas of the brain operating at a measurable level of activity at an given time. But does that necessarily mean that the other areas are doing nothing? What it may show is that the DEGREE of activity is related to the nature of the task, and therefore will be variable throughout the day (and night). So like I said, the question makes sense. But that doesn't mean we can give a nice neat answer right now.
A reflex action or reflex arc bypasses the brain as to decrease transmission time from detection to response, i.e. the time it takes for the body to initiate a response in relation to the effecting stimulus. This decrease in time allows for minimal damage to tissue or surrounding cells which may be affected by a certain stimulus.
Yes, a person's reaction time is controlled by the brain. The brain processes information received from the environment and sends signals to the muscles to respond accordingly. Faster reaction times can be influenced by factors such as practice, genetics, and overall health of the brain.
The notion that we only use some fraction of our brain is based on an oversimplification of an outdated understanding of how the brain actually works (in other words, it's wrong). It may be true that at any given time only a small fraction of your neurons are firing, but that's more because you don't often have a need for the neurons that govern, say, remembering exactly what benzaldehyde smells like (cherries, if you're interested). There's no reason to think that geniuses use a "higher percentage" of their brains than anyone else.... they just do it better, somehow, and we really don't understand exactly how. There is no secret, chemical or morphological, behind a genius using his brain more effectively and successfully than many others. He simply keeps his neurons free of other electrical and chemical impulses, impurities, disturbances, disruptions, cross-currents and short-circuits such as those caused by sudden or continuing erruptions of anger, hate, lust and so on. The ancient Indian philosophers have defined this state of the resultant chemical and electrical special balance as Cleanliness Of Conscience or Kundtalini. Where many people are prone to diverge in their thoughts, emotions and feelings, they are clear-conscious enough to make them converge, thereby reducing the need for using more neurons. Anyway complex thoughts result in the formation of more chemical combinations and more intense and intricate electrical discharges. The projecting of the fore head frontwards in the cource of evolution increased the internal volume of the skull by which more quantity of brain could it contain, which has been critical in the emergence of intellect in man. The erection of the backbone unlike in animals also has been a critical factor. When the backbone remained horizontal to the axis of the Earth, all the excess energy produced was being arrested and pulled down to earth by the gravitational force. But once it became erect, it was freed from the magnetic pull of the earth and all excess and unused energy went straight to the brain and it developed. It is not strange that a sitting sleeper is more conscious and alert than a lying sleeper. When compared to animals, all men are geniuses once they get rid of all rubbish in their brain and do not overcrowd it.
Dolphins only sleep using half of their brain at a time, so they will still be above water and conscious of what they are doing when half of their brain is asleep, so they will still be breathing
Its all electricity in a nueron in our brain. But the complex question is, how can electricity form what we see and store it in our brain for a life time. Electrons would have to be very smart. Wave links form houses, they form sound, smell. But we can not see our thoughts under a microscope. Thoughts area invisible but, energy is visible in waves. I believe thoughts area stored and transferred there Cartesian dualism.
Not many knew about them at the time.
The number of thoughts a person can have at one time varies widely and is difficult to quantify. While some studies suggest that the average person may have thousands of thoughts per day, they typically focus on a few key ideas or concerns at any given moment. The brain is capable of multitasking, but cognitive overload can hinder effective thinking. Ultimately, the capacity for simultaneous thoughts depends on individual cognitive processes and external distractions.
It's called "A Train of Thought" for a reason. Anytime you get more than one on the same set of tracks, "Someone's losing a caboose"! :-) Personally, I have been able to accomplish 1/2 thought at the same time!

The brain does not create consciousness, yet to some extent it creates thoughts within the realms of consiousness. Even a person in a coma might have conscoiusness. Read the recent article from time site
There is no time limit for such surgery. It could be 3 - 8 hours (generally no more than 8 hours.) It depends where the blood clot is and how difficult it is to contain.
They have a brain the whole time; as a matter of fact, they get to keep it!
Yes but ...Because of their undersea environment, whales and dolphins have to actively decide when to breathe - they are conscious breathers.As they have to be conscious to breath, this presents a problem for them to sleep and they solve this by letting one half of the brain sleep at a time and in this way, the animal is never completely unconscious, but it still gets the rest it needs.
Jocelyn has been on Brain Surge one time.
the brain is more active during the day because of thoughts,memories,and "brainfarts". these mostly happen during the day after a long period of time. such as if you write, you mostly see mistakes after a few days.
