The funniest, best-sung song by an epigenetic neuroscientist ever!

The singer, Dr. Rachel Yehuda showed that the gene expression of pregnant Holocaust & 9/11 survivors were altered by the experiences, as were those of their children. But here she’s just having fun!

‘Adult entertainment’ may be the ultimate misnomer.

[This is a great example of an article having little to so with neuroscience save the use of the word.]

Two hundred years ago in the U.K., if you said you were going to a “gentleman’s club,” it was understood you were going to a private upper-class establishment where you could relax, read, play parlor games, get a meal, and gossip with others of your class. Today, in the U.S., if you said you were going to a “gentleman’s club,” it is assumed you will be paying to see a striptease in a low-lit bar.

Is this really what should typify a “gentleman”?

Pornography is often classified, along with other sexually oriented businesses, as “adult” entertainment—something for “mature” audiences. If this meant that these kinds of entertainment are “not suitable for children” then few would protest.

The very thing in the brain that is the mark of adulthood and maturity is the thing that is eroded as we view more porn. It is as if the brain is reverting, becoming more childlike. “Adult” entertainment is actually making us more juvenile.

That said, it would be foolish to use this as an argument that pornography is suitable for adults. Heroin and methamphetamines are also “not suitable for children,” but this does not mean, ipso facto, that they are healthy for those over the age of 18.

#Neuroplasticity and Training the Older Brain #neuroscience #seniorsrock

Neuroplasticity is the brain and nervous systems ability to evolve and to repair deficits.
At a basic level it represents the ability to learn and develop a structural and functional system to interact with the environment.
The brain’s neuroplasticity is maximized during childhood and adolescence. This adaptability wanes with age. However, some neuroplasticity ability persists in the older brain.
This persistence was highlighted in a study from Hong Kong recently published in the journal Neural Plasticity.
Natalie Leung and colleagues studied a group of older adults with an average age of 70 years. Two hundred nine older adults were randomized to a cognitive training protocol or a control video education intervention.
The cognitive training protocol involved three one-hour training sessions for 13 weeks (39 hours total cognitive training). The training in this protocol was adapted from the Brain Fitness Program of Posit Science. Elements including tasks focusing on reaction time, visual discrimination, verbal memory, attention and working memory. All subjects completed neuropsychological assessment at baseline and at the end of the 13-week trial.
The active training groups demonstrated significant improvement in a variety of cognitive domains compared to the control group including:
  • Higher sustained attention scores on the Seashore Rhythm Test
  • Better performance on working memory digit span tasks
  • Better performance on visual-spatial cognition 
This study did not include a brain imaging component. However, the author’s note their findings suggest sensitive imaging tools might complement their results and provide better understanding of structural and functional elements of neuroplasticity in the older brain.
 
The role of brain training in modifying the effects of aging on the brain is still in early stages of research. However, the current study supports the ability of elderly individuals to respond to cognitive training interventions.

Can You Get Smarter? – The New York Times

YOU can increase the size of your muscles by pumping iron and improve your stamina with aerobic training. Can you get smarter by exercising — or altering — your brain?

This is hardly an idle question considering that cognitive decline is a nearly universal feature of aging. Starting at age 55, our hippocampus, a brain region critical to memory,shrinks 1 to 2 percent every year, to say nothing of the fact that over 40 percent of Americans age 74 and older have Alzheimer’s disease. The number afflicted is expected to grow rapidly as the baby boom generation ages. Given these grim statistics, it’s no wonder that Americans are a captive market for anything, from supposed smart drugs and supplements to brain training, that promises to boost normal mental functioning or to stem its all-too-common decline… read more: Can You Get Smarter? – The New York Times

#Neuroscience of #Chicago #Cubs Fans – YouTube

C2ST Artist in Residence Aaron Freeman pretends to interview Stanford University Neurobiology professor Robert Sapolsky on the difference between the brains of Chicago Cubs fans and those of lesser beings.  According to Sapolsky part of the difference may have  to do with higher sustained levels of the neurotransmitter dopamine.
