  • The major finding was that increased working memory capacity following training was associated with changes in brain biochemistry. Specifically, the researchers found changes in the density and binding potential of cortical D1 dopamine receptors in brain regions that are activated during working memory tasks.

Phasic Firing Of Dopamine Neurons Is Key To Brain's Prediction Of Rewards - 0 views

  • Our research findings provide a direct functional link between the bursting activity of midbrain dopamine neurons and behavior. The research has significant applications for the improvement of health, because the dopamine neurons we are studying are the same neurons that become inactivated during Parkinson's Disease and with the consumption of psychostimulants such as cocaine and amphetamine
  • Midbrain dopamine neurons fire in two characteristic modes, tonic and phasic, which are thought to modulate distinct aspects of behavior. When an unexpected reward is presented to an individual, midbrain dopamine neurons fire high frequency bursts of electrical activity. Those bursts of activity allow us to learn to associate the reward with cues in our environment, which may predict similar rewards in the future.
  • When researchers placed the mice in reward-based situations, they found that the mice without the NMDA receptor in their dopaminergic neurons could not learn tasks that required them to associate sensory cues with reward. Those same mice, however, were able to learn tasks that did not involve an association with rewards.

  • 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).

neurophilosophy brain LTP learning memory

shared by Tero Toivanen on 11 Mar 09 - Cached
  • Now referred to as long-term potentiation (LTP), this mechanism has since become the most intensively studied in modern neuroscience,and is widely believed to be the cellular basis of learning and memory, although this is yet to be proven unequivocally.
  • In the new study, Santiago Canals of the Max Planck Institute for Biological Cybernetics in Tübingen and his colleagues used the same protocol to induce LTP. But while the vast majority of researchers have investigated LTP in slices of hippocampal tissue, this study involved observing LTP in live animals.
  • This new research provides the first evidence that the local modifications in synaptic connections induced by LTP lead to long-lasting changes in the activity of a diffuse network of brain regions, and even to facilitated communication between the two hemispheres. The fMRI data showed that hippocampal LTP recruits higher order association areas, as well as regions involved in emotions and others subserving different sensory modalities, all of which are known to be involved in memory formation.

shared by Tero Toivanen on 23 Mar 09 - Cached
  • A Northwestern research group has found that people that solve anagram puzzles by sudden insight rather than by conscious search or analytic strategies have an EEG resting state that prefers the right over the left hemisphere.
  • How often it does seem that it's the highly creative child who is having the greatest struggles in the conventional classroom! It's nice finding research that backs up the association. From this Harvard study, a diffuse attentional style was much more common among individuals with high lifetime levels of creative achievement.
  • The study concludes with a final interesting finding that differences in this attentional style might account for why high IQ beyond a certain point doesn't correlate with higher levels of creative achievement (the threshold effect...e.g. that once one is beyond 120, higher numbers don't correlate with enhanced achievement). If a focused vs. diffuse attentional style is taken into account, then it becomes more evident that diffuse attentional style + high IQ are important factors that contribute to high levels of creative achievement.
