Understanding the Brain’s “Brake Pedal” in Neural Plasticity: Scientific American

Understanding the Brain’s Brake Pedal in Neural Plasticity: Scientific American 

wow! could my 60-year-old brain become more like it was when i was younger? when i could remember all of the words that i cannot pull out of memory while lecturing or just talking? when i could remember names (well, sort of remember them)? when i could work more efficiently, getting more done? when i could concentrate, pay attention, and hear better? as this article indicates, at my age the brake pedal has been pushed down — not pedal to the metal, as in senility. but enough to let me know that i am not the me i was at 28, which is the age i still imagine myself to be. but the mirror reminds me that the inevitability of age shows in the face and neck, the hands, and the extra-padded frame. what we know about the brain is so astonishing to me, because when i was a girl, all we knew was that aging caused an inevitable deterioration of brain cells. now we know that the brain is indeed plastic — reacting to changes in our environment, creating neurons and their magical paths from one part of the brain to another. if i were 12 today, i might decide to study the brain. from my perspective, the brain is the final frontier.

Bring Change 2 Mind

Media_httpwwwbringcha_xpzaf

actor glenn close has family members with mental illnesses, and she helped form this organization to erase the negative valence associated with mental disorders — depression, anxiety, bi-polar disorder, post-traumatic stress disorder, schizophrenia, and such. you can reach it at http://www.bringchange2mind.org.

— i have also had family members with problems like these, and i inherited unbalanced brain chemistry. it’s been nearly 40 years since i first sought help for depression. in addition, i was a victim of physical abuse a few years ago and experienced post-traumatic stress disorder as a result. downer, right?

— Medication 2010: it’s a new world, with a much more sophisticated understanding of the brain and how it works. now there are drugs targeted at achieving specific outcomes. you need to see a psychiatrist — hopefully someone under 40-45 — who understands the differences between the most recent medications and the therapeutic dosages. your family doctor or internist just doesn’t know enough to treat mental illness effectively. but this person can refer you to a psychiatrist.

— Talk therapy 2010: Flash — talk therapy actually causes changes in your brain. you may need a good psychologist and a good psychiatrist. they work in tandem. avoid psychologists who, after listening to your problems, just say “i feel your pain.”

— Insurance 2010: my employer’s medical insurance covers physical and mental illness in the same way. i just pay the co-pay that i pay for any specialist. prescriptions are also covered the same. this is a huge change and definitely overdue.

— if you need help, consult your doctor, talk with a friend who knows about treatment options, call in-crisis support 800-273-8255, or call 911. get help now.

— 1 in 6 adults experiences a mental illness in his or her lifetime. sometimes these last a few months or a few years, and sometimes they last a lifetime. there’s no shame in saying that you are being treated for a mental illness, and there’s no shame in seeking help.

Mind – Research Upends Traditional Thinking on Study Habits

Media_httpgraphics8ny_wjacc

Take a look at the article on how people learn. Psychologists have found that studying the same material in two different locations (e.g., inside, outside) increases retention of information compared with studying material twice in the same location.

Now, think about how people consume news. If they use more media to access the same information (e.g., about an election), do they know more than if they rely on one medium, even if the hallowed New York Times? If so, is it a matter of different, additional information being available in different media, OR is it merely because essentially the same information is “studied” twice in different media “locations”?

Food for research thought.

The Fear Factor: When the Brain Decides It’s Time to Scram: Scientific American

Media_httpwwwscientif_tjzgi

i like this idea of the duality of fear responses. first comes scanning the environment and identifying a potential threat. second comes taking action to avoid it. this fits my own bio-cultural theory of news. first, people continually scan the environment for potential threats, usually via the news. second, they may take action, such as political activism, discussing drugs with their kids or avoiding vacations in locales with lots of crime.

The Naked Truth: Why Humans Have No Fur: Scientific American

this Scientific American subscription teaser includes a statement that makes me wonder if it was written by the advertising staff and not an evolutionary scientist : “The evolution of hairlessness helped to set the stage for the emergence of large brains and symbolic thought.” i eagerly await the longer article (perhaps books?) that provide the logic behind this. we need to take care when making blatantly causal statements, even when couched as “setting the stage for.”
