The Brain that Changes Itself: Stories of Personal Triumph from the Frontiers of Brain Science by Norman DoidgeAn astonishing new science called neuroplasticity is overthrowing the centuries-old notion that the human brain is immutable. Psychiatrist and psychoanalyst, Norman Doidge, M.D., traveled the country to meet both the brilliant scientists championing neuroplasticity and the people whose lives they’ve transformed - people whose mental limitations or brain damage were seen as unalterable. We see a woman born with half a brain that rewired itself to work as a whole, blind people who learn to see, learning disorders cured, IQs raised, aging brains rejuvenated, stroke patients learning to speak, children with cerebral palsy learning to move with more grace, depression and anxiety disorders successfully treated, and lifelong character traits changed. Using these marvelous stories to probe mysteries of the body, emotion, love, sex, culture, and education, Dr. Doidge has written an immensely moving, inspiring book that will permanently alter the way we look at our brains, human nature, and human potential.
New insight into the brain's ability to reorganize itself
Unit 3 Questions. Describe all parts of the process. How do nerve cells communicate with other nerve cells? How do neurotransmitters influence behavior, and now do drugs and other chemicals affect neurotransmission? What are the main neurotransmitters and their functions? What happens if they malfunction?
Brain and Behavior
Brain plasticity, also known as neuroplasticity, is a term that refers to the brain's ability to change and adapt as a result of experience. When people say that the brain possesses plasticity, they are not suggesting that the brain is similar to plastic. - Shared Flashcard Set.
The frontal lobes, which are also called the cerebral cortex, are the seat of emotions and judgments related to sympathy, which is the ability to feel sadness. Chapter 2 Brain and Behavior The cerebral cortex outer layer of the cerebrum has the two largest hemispheres that covers the upper part of the brain which are divided into smaller portion called lobes. Corticalization is an increase in size of the wrinkling of the cortex and without this we would not be any smarter than any other animal. Cerebral hemispheres are divided into right and left halves of the cortex connected by thick band axon fibers called corpus. Hemispheric specialization, testing. Cognitive functions may be defined as the abilities of a person to process information and thoughts.
Alison Heather May 15, When the brain's primary "learning center" is damaged, complex new neural circuits arise to compensate for the lost function, say life scientists from UCLA and Australia who have pinpointed the regions of the brain involved in creating those alternate pathways — often far from the damaged site. The researchers found that parts of the prefrontal cortex take over when the hippocampus, the brain's key center of learning and memory formation, is disabled. Their breakthrough discovery, the first demonstration of such neural-circuit plasticity, could potentially help scientists develop new treatments for Alzheimer's disease, stroke and other conditions involving damage to the brain. For the study, Fanselow and Zelikowsky conducted laboratory experiments with rats showing that the rodents were able to learn new tasks even after damage to the hippocampus.
Scientists once thought that the brain stopped developing after the first few years of life. To learn more about neurons, click here. Because of this belief, scientists also thought that if a particular area of the adult brain was damaged, the nerve cells could not form new connections or regenerate, and the functions controlled by that area of the brain would be permanently lost. However, new research on animals and humans has overturned this mistaken old view: today we recognize that the brain continues to reorganize itself by forming new neural connections throughout life. This phenomenon, called neuroplasticity , allows the neurons in the brain to compensate for injury and adjust their activity in response to new situations or changes in their environment. How does neuroplasticity work?
