Creativity and the Aging Brain | Psychology Today Blogs - 0 views

  • So instead of promoting retirement at age 65, perhaps we as a society should be promoting transition at age 65: transition into a creative field where our growing resource of individuals with aging brains can preserve their wisdom in culturally-valued works of art, music, or writing.
  • Numerous studies suggest that highly creative individuals also employ a broadened rather than focused state of attention. This state of widened attention allows the individual to have disparate bits of information in mind at the same time. Combining remote bits of information is the hallmark of the creative idea.
  • Other studies show that certain areas of the prefrontal cortex involved in self-conscious awareness and emotions are thinner in the aging brain. This may correlate with the diminished need to please and impress others, which is a notable characteristic of both aging individuals and creative luminaries.

  • Finally, intelligence studies indicate that older individuals have access to an increasing store of knowledge gained over a lifetime of learning and experience. Combining bits of knowledge into novel and original ideas is what the creative brain is all about.

    The aging brain resembles the creative brain in several ways. For instance, the aging brain is more distractible and somewhat more disinhibited than the younger brain (so is the creative brain). Aging brains score better on tests of crystallized IQ (and creative brains use crystallized knowledge to make novel and original associations).

BBC NEWS | Science & Environment | Simulated brain closer to thought - 1 views

  • A detailed simulation of a small region of a brain built molecule by molecule has been constructed and has recreated experimental results from real brains.
  • While many computer simulations have attempted to code in "brain-like" computation or to mimic parts of the nervous systems and brains of a variety of animals, the Blue Brain project was conceived to reverse-engineer mammal brains from real laboratory data and to build up a computer model down to the level of the molecules that make them up.
  • The first phase of the project is now complete; researchers have modeled the neocortical column - a unit of the mammalian brain known as the neocortex which is responsible for higher brain functions and thought.

  • "It starts to learn things and starts to remember things. We can actually see when it retrieves a memory, and where they retrieved it from because we can trace back every activity of every molecule, every cell, every connection and see how the memory was formed."
  • "The next phase is beginning with a 'molecularisation' process: we add in all the molecules and biochemical pathways to move toward gene expression and gene networks. We couldn't do that on our first supercomputer."
  • Organised columns of neurons have been simulated molecule by molecule
  • "This is very interesting research and I'm not criticising it, but it doesn't help us in computer science in having the intelligent behaviour of humans replicated." Professor Markram believes that by building up from one neocortical column to the entire neocortex, the ethereal "emergent properties" that characterise human thought will, step by step, make themselves apparent.
