Neuroplasticity: How the brain changes with learning

You cannot learn something without storing it in some form of memory for future use. From neuroscience, we know that memories are encoded by physical changes in the brain. In other words, your brain changes physically whenever you learn anything, and your brain continues to be moulded by experience and learning throughout your life.

Executive summary

        • Your brain is never fixed but continues to change with learning and experience throughout your life.

        • Most learning in the brain involves rewiring or making and strengthening connections between neurons, the cells of your brain most crucial for learning.

        • In most regions of the brain, the only neurons you will have throughout all of your life are already present at birth. Your brain does continue to grow new neurons in at least one very small but potentially important area for learning, but this is very new research and the role of these new neurons for learning is not yet known.

        • Neuroplasticity is important for all learning – much of the neuroscience research on neuroplasticity is related to how the brain recovers from injury or damage – but some of the same principles apply to how the brain changes with learning throughout all of life.

Learning and memory and changes in the brain

Let us start with a simple logical argument, to dispel myths and show that logically, of course, your brain is changing with learning:

Learning and memory are necessarily closely linked. You cannot learn something without storing it in some form of memory for use in the future, either for recall as new knowledge or improvement in skills. From neuroscience, we know that memories are encoded by physical changes in the brain (although we still debate exactly what it is that changes and how). Your brain therefore changes physically whenever anything is learnt, and so your experiences and learning throughout all of life change and mould your brain. 

There is a common brain myth or popular perception that the brain becomes fully developed sometime in early childhood, implying that nothing further changes, and that further changes in the brain with development in childhood and adolescence are somehow biologically determined, leading to a fully developed state at adulthood.

In reality, the way your brain develops is determined both by your genetics and by your learning and experiences. Biological does not mean predetermined. Your brain is shaped by your experiences and is never fixed but continues to change along with learning across the lifespan.

The Impact of the Gulf Oil Spill on the U.S.

www.freewebs.com/mathewstolte/oilspills.html. 21/06/2010

      Although the oil has been pouring into the Gulf of Mexico for months, the consequences of this larger than ever environmental disaster have yet to be fully examined and determined. Scientists and researchers have started to put together some of the puzzle pieces, and the impact of the Deepwater Horizon oil spill are likely to be big.

      North Americans will have fewer choices on the store shelves. The Gulf of Mexico is a huge shipping lane through which products of all shapes and sizes come into North America. From toys to clothes to cars to building materials, you may find that the selection at your local store begins to shrink as shipping lanes slow down as a result of the oil spill.

      Whether you’re taking a vacation or hoping to walk along the shore, you may be disappointed. Many beaches in the U.S.A. are now closing as clean-up efforts on removing oil slick from the sands. But the impact may be felt for quite some time as oil continues to wash up on shore.

      Many wildlife animals will be impacted by the oil spill. Oiled birds, otter, bald eagles, pelicans, turtles, fish, and dolphins are already washing up on shore, making the beach sights less than palatable for someone looking to see some pristine nature.

      Over time, molluscs like clams incorporate calcium into their shells throughout their lifetimes. But the heavy metals like nickel and vanadium from the petroleum industry and the resulting oil spill may be incorporated into the shells of these creatures. As other wildlife consumes these clams, they incorporate the toxins into their bodies, and on it goes as the heavy metals bio-accumulate in the food chain. This could have serious, long-term consequences for human health. 

      Environmentalists have been working on restoring the populations of oysters by reseeding certain reefs to boost their numbers. The Gulf of Mexico has been home-working on some of these projects, but with the massive oil spilling into that environment, the oysters could soon become tainted with chemicals, making them unsafe to eat.

      The Gulf of Mexico is also a nursery for species like shrimp that grow up in the estuaries. The oil that is taking over this natural environment will choke out the plants that make the estuaries so nutritious to shrimp. 

      According to the National Weather Service, a hurricane like Hurricane Katrina could have a devastating impact on New Orleans. Researchers expect 15 named storms to develop into 8 hurricanes, and with a well-placed hurricane, the oil could be pushed onto New Orleans shores, further impacting the already devastated region.
