Aging paragons

We all know a few older-aged paragons, individuals who are still storming through life in their 9th or 10th or 11th decade. I was delighted to read two articles in the New York Times last week that featured two such individuals who have crossed my own path in life. David Perlman is a 90-year-old science…

Brain plasticity and criminal behavior; part 4

A young adult American – usually male – has committed a crime. He stands in the dock. As we sit as courtroom observers, what, in the overwhelming majority of the cases, do we see before us? As we’ve discussed in earlier blogs: 1. We see a young man who has failed at school. There is…

A little more neuroplasticity help is on the way!

I’ve spent the past 2 days participating in a workshop at the National Institutes of Health titled “Harnessing Neuroplasticity for Human Applications”. You would probably have enjoyed – and learned from — listening in on these discussions. The participants at this meeting (including many top American gurus and practitioners in neuroplasticity) outlined the state or…

Perception, illusion, prediction, magic, autism

There is an enjoyable article in the current issue of Wired in which the magician Teller (the silent, smaller and more sneaky chap on the Penn and Teller team) engages in a conversation with the science writer Jonah Lehrer about the neurological bases of magic. Reading this article led me to a review on this…

Brain plasticity origins of PTSD

John Woo, a fellow University of California professor and self-identified neurological expert on methods of interrogating prisoners argued that recommended methods of interviewing prisoners (like ‘water-boarding’, sustaining a detainee in an agonizing posture for extended periods of time, or long bouts of sleep deprivation) were acceptable, because experience with former prisoners of war have shown…

Genetics explanations for neurological & psychiatric illness

There is an interesting set of commentaries in the current issue of The New England Journal of Medicine in which scientists reflect on why genetic screening strategies have had such limited value, for explaining the risks of onset of the great human diseases and disorders. There has been a longstanding presumption (most strongly held by…

Seeing fast-moving things at an older age

Dr. John Andersen recently visited our research group from his laboratory at the University of California at Riverside, to help us understand important studies conducted in his laboratory documenting some aspects of change in the visual perceptual abilities of older individuals. He and his colleagues have conducted a number of important and provocative studies that…

Brain plasticity and criminal behavior; part 2

This post is a continuation of my previous post, Brain plasticity and criminal behavior part 1 Now, let’s consider the child in which “all does NOT go well”. 1) What if the schedules of interaction between the child and his primary caregiver(s) are sparse? 2) What if interactions are more often negative than positive? 3)…
