You can forget it later. It may seem like you've trained the brain to "read" with music, but not "comprehend" with music.<br /><br />>> Out brain is amazingly talented and it may not be possible to decide how it can be multitasking.<br /><br />Yes! The brain is so proficient that it makes us ask ourselves: <i>Is it really doing multitasking?!</i><br /><br />Even though our perception changes, the activities are same. May be that's why they say, perception makes a difference or where there is a will, there is a way :-)Harisha - ಹರೀಶhttps://www.blogger.com/profile/06053781336265673367noreply@blogger.comtag:blogger.com,1999:blog-11564855.post-91466916430474807002010-09-18T15:20:44.285+05:302010-09-18T15:20:44.285+05:30@Namitha & ಮನದಾಳದಿಂದ,

When I read a text book, I get disturbed by the music, but when I read some story, music never seems to bother me.<br />I guess, this may be because I am more interested in reading stories. <br /><br />When we learn driving, changing gears, brake, clutch and steering control seem to be individual activities. Once we say we learned driving, it means we have considered driving activities (gear, brake, clutch and steering control) as one instead of multiple activities. The perception changes and we focus on driving as a whole.<br /><br />Multitasking for computers may not actually mean doing things together, but it may be a context switch mechanism. Out brain is amazingly talented and it may not be possible to decide how it can be multitasking.Chaithrikahttps://www.blogger.com/profile/02731311200267214721noreply@blogger.comtag:blogger.com,1999:blog-11564855.post-81710613991692547712010-07-27T16:51:00.798+05:302010-07-27T16:51:00.798+05:30harishaaa,

I came across the following points:<br />* Voluntary actions involve Cerebrum, which is slow.<br />* Involuntary actions do not involve Cerebrum. It may involve due to nervous system and/or other parts of the brain and spinal cord.<br /><br />However, I couldn't get any reference which says that the brain does context switch as CPUs.Harisha - ಹರೀಶhttps://www.blogger.com/profile/06053781336265673367noreply@blogger.comtag:blogger.com,1999:blog-11564855.post-34662304409239625262010-03-25T22:23:53.040+05:302010-03-25T22:23:53.040+05:30@Harish,

I think you missed the point here. Although...@Suri,<br />I think you missed the point here. Although human brain and CPU seem to be doing their job in a similar way, they don't really do so. If you really want me to compare brain to CPU, then I would compare it to a multi-core processor, possibly a processor with infinite cores, each of which is capable of doing a task separately.<br /><br />When you talk about involuntary actions, again there should be some part of the brain dedicated to handle it: your hand should be aware of the burning sensation, that signal should it should reach some organ, and that organ should send a signal back to your hand and then the hand should retract. Here the organ which receives the signal & sends it back is, most probably, brain. Only difference is that the signal transfer happens between hand & brain ONLY, without interacting with your mind, conscious or subconscious.<br /><br />This is like a DMA transfer, if you ask me :-P<br /><br />To put it all together, since brain is an analog in nature, I don't really think there is a "context switch" at all.Harisha - ಹರೀಶhttps://www.blogger.com/profile/06053781336265673367noreply@blogger.comtag:blogger.com,1999:blog-11564855.post-5554352214869493702010-03-22T21:56:18.633+05:302010-03-22T21:56:18.633+05:30@Santosh:

Since it's very small, you hardly notice it.<br /><br />Apply the same to human brain, the brain switches to and fro between tasks, so fast that it hardly is recognizable.<br /><br />However when actions are involuntary, brain is not involved at all. E.g. You shy away from fire.<br /><br />IMHO, if a task requires brain, it can process only one thing at a time and never more than that.<br /><br />What training the brain actually does is that it helps the brain to manage the context switches very swiftly and efficiently.Suresh S Murthyhttps://www.blogger.com/profile/03282732422693045780noreply@blogger.comtag:blogger.com,1999:blog-11564855.post-49282862648002538692010-03-13T17:17:32.422+05:302010-03-13T17:17:32.422+05:30It's been many days.
