How do thoughts originate in human brain ?

thoughts occur all over the brain. some are subconscious and available via dreams and some are conscious i.e. thinking about where u left your keys. While u think many of the millions an millions of neurons will fire in different areas. if your tryin to remember where the keys are, then the area where memory is located will be firing proportionally more.

This is what we spend all that time in school for... were you paying attention and doing the work? lol!\n\nIt is not the first impulse or first fleeting idea that we control, but what we do with it. If you let go of negative impulses and thoughts, and grab hold of positive impulses and thoughts, you will condition your mind to only produce the ones you want to have.

The brain controls "lower" or involuntary activities such as heartbeat, respiration, and digestion - these are known as autonomic functions. The brain also controls "higher" order, conscious activities, such as thought, reasoning, and abstraction. The human brain is generally regarded as more capable of these higher order activities than any other species.\n\nThe human brain is thought to be the source of the conscious, cognitive mind. The mind is the set of cognitive processes related to perception, interpretation, imagination, and memories, of which a person may or may not be aware. Beyond cognitive functions, the brain regulates autonomic processes related to essential body functions such as respiration and heartbeat.\n\nExtended neocortical capacity allows humans some control over emotional behavior, but neural pathways between emotive centers of the brain stem and cerebral motor control areas are shorter than those connecting complex cognitive areas in the neocortex with incoming sensory information from the brain stem. Powerful emotional pathways can modulate spontaneous emotive expression regardless of attempts at cerebral self-control. Emotive stability in humans is associated with planning, experience, and an environment that is both stable and stimulating, especially during early developmental years.\n\nThe 19th century discovery of the primary motor cortex mapped to correspond with regions of the body led to popular belief that the brain was organized around a homunculus. A distorted figure drawn to represent the body's motor map in the prefrontal cortex was popularly recognized as the brain's homunculus, but function of the human brain is far more complex.\n\nThe human brain appears to have no localized center of conscious control. The brain seems to derive consciousness from interaction among numerous systems within the brain. Executive functions rely on cerebral activities, especially those of the frontal lobes, but redundant and complementary processes within the brain result in a diffuse assignment of executive control that can be difficult to attribute to any single locale.\n\nMidbrain functions include routing, selecting, mapping, and cataloguing information, including information perceived from the environment and information that is remembered and processed throughout the cerebral cortex. Endocrine functions housed in the midbrain play a leading role in modulating arousal of the cortex and of autonomic systems.\n\nNerves from the brain stem complex where autonomic functions are modulated join nerves routing messages to and from the cerebrum in a bundle that passes through the spinal column to related parts of a body. Twelve pairs of cranial nerves, including some that innervate parts of the head, follow pathways from the medulla oblongata outside the spinal cord.\n\nA definite description of the biological basis for consciousness so far eludes the best efforts of the current generation of researchers. But reasonable assumptions based on observable behaviors and on related internal responses have provided the basis for general classification of elements of consciousness and of likely neural regions associated with those elements. Researchers know people lose consciousness and regain it, they have identified partial losses of consciousness associated with particular neuropathologies and they know that certain conscious activities are impossible without particular neural structures.

The heart simply pumps the blood to supply the brain with "power." The heart cannot live without the brain, and the brain cannot live without the heart. Along these lines of thinking, that the two work in perfect tandem, I believe that is why we say that some emotions come from the heart. \n\nUsually, we associate sentimental or sensual emotions with the heart and knowledge or intelligence/common sense with the brain, when really, they all originate in the brain. But I think it's a great metaphor to indicate emphasis on your feelings when you are trying to communicate how you feel. This heart vs. brain thing seems to be a phenonmenon across cultures and languages. \n\nJust a side note: the ancient egyptians thought that the heart was the main thinking and reasoning organ of the body so this was one of the only organs that they would leave IN the body during mummification. They would extract other organs that they felt weren't necessary for the afterlife (liver, kidneys....and the brain). They thought that the heart was the essential organ so that they could function in the afterlife.

Then, what is a thought??  We always try to separate the mind from the body.  For instance,  is something a mental or physical problem.  A thought in your mind is a really physical complex interaction that involves neurotransmitters and electrical signals.  So when someone feels pain whether its chronic or acute, yes it is a thought yes there is a specific chain of reaction  that is occuring in the body and head.

Actually, linguists postulate that we think in a kind of 'thought-language' that can process several concepts simultaneously. The question of whether that 'thought-language' is innate, and international, is one of the biggest in modern theoretical linguistics. So is just what that 'thought-language' is and how it works.\n\nFor myself, when I'm thinking quickly, I presume that I'm using that language but also 'translating' it to English. When I speak a second language, though, I find that I am capable of 'thinking in that language' - which probably means I'm translating directly from 'thought-language' to the second language. As I speak more than one language in my day-to-day life, I'll find that I have dreams wherein a conversation is held. I'll remember everything about the topic of conversation, but I can't quite recall what language we were speaking!

There are important structures in the base brain that control breathing, metabolism and other essential life sustaining issues.\n\nThe frontal is more Analytical thinking, refraining from saying odd things.  Emotional stuff.

One of the differences is in how much pre-frontal lobe cortex we have. The pre-frontal lobes have to do with "connecting the dots"...logical analysis, association...it allows us to visualize the future, make rationale judgments and plan. For this reason hey call it the "executive" part of the brain. In humans, 33% of the cortex, the thinking part of the brain, is frontal. In chimpanzees, it's only about 10%. That's a huge difference, signifying that humans have a whole lot more of the kind of brain function that produces higher level intelligence.

Interesting puzzle:\nfMRI studies have shown that neurons in the brain associated with a task begin to fire about 800 milliseconds before the person is even aware that they want to perform an action.\n\nIs this God? Do we have no free will? Is this our soul?\n\n\n                     Med Hypotheses. 2001 Mar;56(3):364-6. \n    If there were no free will: Fisher CM.\n\n\n    Electrophysiological findings in humans who are performing voluntary acts, indicate that the intention to act, follows brain activity rather than preceding it. This has implications for voluntary behavior and the doctrine of free will. This essay reviews the fields of human behavior, including medicine, in which this new thesis might have far-reaching significance. Copyright 2001 Harcourt Publishers Ltd.\n\nAn extract:\n\n...it should be pointed out\nthat somewhat the same conclusion may be reached on\nthe basis of rather elementary observation. Every thought,\nfeeling, inclination, intention, desire, every mental\nimpression no matter how brief or faint, must be created\nby nervous system activity. How else could they arise? Ideas would have to arise without a physical basis.\nNervous system activity must always precede. Every\nnuance of thought and feeling arises in and must be preceded\nby its own specific electrical configuration in the\nbrain. If one has the experience of ‘willing’ the nervous\nsystem to do something, the impression of ‘willing’ must\nhave been preceded by nervous system activity.\nOtherwise there would be no source and we are in the\nrealm of the supernatural. Before I think of anything, it\nmust first have taken form in my nervous system.\n\nAh yes, the nervous system... some may just call this the soul...\n\n\nEdit: in reference to the below answer, I've pulled out a (scientific) study that does not suggest that there is no soul.\n\n Hist Philos Life Sci. 2004;26(3-4):377-94. \n\n    'Show me your original face before you were born': the convergence of public fetuses and sacred DNA.\n\n    Gilbert SF, Howes-Mischel R.\n\n    Department of Biology, Swarthmore College, 500 College Avenue, Swarthmore, PA 19081, USA.\n\n    Embryology is an intensely visual field, and it has provided the public with images of human embryos and fetuses. The responses to these images can be extremely powerful and personal, and the images (as well as our reactions to them) are conditioned by social and political agendas. The image of the 'autonomous fetus' abstracts the fetus from the mother, the womb, and from all social contexts, thereby emphasizing 'individuality'. The image of 'sacred DNA' emphasizes DNA as the unmoved mover, the eidos, the soul of the human being. Since fertilization involves the forming of a new constellation of DNA in the zygote, the act of fertilization is being perceived as the secular and technical equivalent of ensoulment. This privileges fertilization above the other possible scientifically valued times when 'human life' begins.

I am not going to give you a lecture like others do.\n\ndreams are from our subconscious mind, based on our daily experience, they reveal your inner personalities like fear, desire.  They can be triggered by media effect, actual event and personal experience..

EDIT: Half of my answer didn't post for some reason.\n\nScientists have been studying this for years, but never have found an answer.\n\nWhen I spoke to a deaf woman about this idea, this is what she said: "When I think about what I am going to say, I think about it in sign and I sometimes sign in my sleep.  However, when I read something (because there is no written version of sign language) I think about it in English.  Concepts are created visually more often than in English."\n\nFor an actual study, when presented with a stimulus, the visual and language areas of the brain become active, whereas in a hearing person, the auditory and language areas of the brain become active.  While they are processed differently, the language area of the brain is used at all times.\n\nThe only other help I can offer is a study on Genie, a girl who was locked up and unsocialized until about the age of twelve.  While she was able to be somewhat rehabilitated and learn some basic vocabulary, she never figured out how to put complex sentences together, which was thought to show she was not capable of complex thought.  However, the data was compromised because it was thought that she may be mentally challenged.

Y'all are placing too much emphasis on the prefrontal cortex.  People with damage to that reason have trouble with things like planning and being socially aware, but the area is not the only one involved in higher thought.  the language centers, for instance, are also involved, and arguably the regions of the brain that might relate to the subject of the question are active.\n\nI don't think one can reasonably localize the process of asking questions to a single locus in the brain.

the brain is the largest consumer of oxygen in our body, though it is one of the smallest organs .......brain requires lot of oxygen every minute and the availability of oxygen therefore infleuences the working of brain\n\nwhen we retain our breath, level of oxygen entering our body is minimised.....As a result, the brain doent get sufficient oxygen and the thinking process slows down

Emotions originate from the limbic system in the brain.  The limbic system is actually several components within the brain that control the fight or flight response, hunger, thirst, fear, bliss, sadness, short and long-term memory, etc.\n  \nSensory perception, things we see and touch is linked to some part of our memory and we associate a response with the given object.  Fire is a good example, at an early age one is taught that fire burns and hurts, that is embedded into our memory so we behave and particular way around fire.  Emotions work the same way, one associates particular feelings(chemical reactions within specific parts of the limbic system) to events, people, places, things, etc.  Any adverse changes to that event, person, place, etc. causes stimulation and a resulting emotion.  I believe hormones(such as dopamine and serotonin) play a huge part in emotions through up or down regulation.\n\nOur emotions make us human, even though primates express emotions such a love, fear, and anger.\nWomen are more emotional than men and that is because there exists a physiological differences(possible?) in the brain and hormonal differences.
