SHOCK TO THE SYSTEMS [ THE NERVOUS SYSTEM ( HARMONY ) ]

SHOCK TO THE SYSTEMS [ THE NERVOUS SYSTEM ( HARMONY ) ] When you’re startled, the two branches work together, regulating the body without any conscious thought needing to be involved. Thanks to these automatic responses, the brain’s cortex is allowed to remain free to do other things-process sensory information, register emotion, pursue rational thoughts,…

SEEING THOUGHTS [ LOOKING INSIDE ( THE AMAZING BRAIN ) ]

SEEING THOUGHTS [ LOOKING INSIDE ( THE AMAZING BRAIN ) ] SEEING THOUGHTS MAGNETOENCEPHALOGRAPHY ( MEG ) also relies on magnetism to examine the brain. In this case, it’s the body’s ambient magnetic fields, not those generated by an external machine, that form the basis of brain imaging. These magnetic fields are extremely weak-perhaps only…

FIRST GLIMPSE / A BETTER LOOK / COMPUTERIZED VISIONS [ THE AMAGING BRAIN ]

FIRST GLIMPSE / A BETTER LOOK / COMPUTERIZED VISIONS [ THE AMAGING BRAIN ] FIRST GLIMPSE The first technology to peer into the brain was the x-ray, invented by Wilhelm Rontgen (1845-1923) in 1895. The German scientist discovered a form of radiation that could penetrate the body; the rays were absorbed by dense bones, which…

OUTSIDE LOOKING IN [ THE AMAGING BRAIN ]

OUTSIDE LOOKING IN [ THE AMAGING BRAIN ] Scientists have long Dreamed of Exammmg how the brain works within a living body. The problem, though, was figuring out how to get inside the head without causing injury or even death. Doctors treating wounds from wars and accidents have been able to get glimpses of living…

LOOKING INSIDE [ SEEING THE BRAIN AT WORK ( THE AMAGING BRAIN ) ]

LOOKING INSIDE [ SEEING THE BRAIN AT WORK ( THE AMAGING BRAIN ) ] ONCE THE brain’s true purpose was ascertained, scientists began finding new ways to observe it and its functions. Starting with noninvasive methods, like IQ tests, they tried to learn more about the living brain and measure how it worked. These intelligence…

ANATOMY [ DIFFERENT PARTS DIFFERENT RESPONSIBILITIES ( THE AMAZING BRAIN ) ]

ANATOMY [ DIFFERENT PARTS DIFFERENT RESPONSIBILITIES ( THE AMAZING BRAIN ) ] THE FRONTAL LOBE A portion of the frontal lobe of each hemisphere called the precentral gyrus controls the body’s movements. Oddly, each hemisphere moves the opposite side of the body, as if the brain’s wiring some-how became crossed. Hence, the movements of the…

ANATOMY [ DIFFERENT PARTS & DIFFERENT RESPONSIBILITIES ( THE AMAZING BRAIN ) ]

ANATOMY [ DIFFERENT PARTS & DIFFERENT RESPONSIBILITIES ( THE AMAZING BRAIN ) ] FOUR DIVISIONS Moving inward, we come to the organ itself. The brain may appear to be a Ulllform mass of folded, pink tissue. But a closer look reveals different lobes, regions, structures, and parts that all help regulate body functions, interpret information…

NERVE CELLS – LIFE SPAN [ THE AMAZING BRAIN ]

NERVE CELLS – LIFE SPAN [ THE AMAZING BRAIN ] Amazingly, the cells that perform the complicated ballet of electrochemical transmission can live more than a hundred years, but they do not get replaced like most other body cells. Except for the hippocampus and the olfactory bulb, where new neurons have been shown to grow…
