neurolearning brain hemispheric creativity Right Hemispheric Thinking

  • 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.

  • The researchers found that by inducing repetitive high frequency firing of a single neuron they could switch the brain state from slow-wave sleep, to rapid-eye movement sleep.
  • Therefore, judging by these three high profile journal papers, a single neuron can make a difference - one neuron firing can change your sleep state, motor movement, or induce a behavior.

musicians' brain synchronize neuroscience brain waves unison

  • The researchers found that the guitarists' brain waves were aligned most during three pivotal times: when they were syncing up with a metronome, when they began playing the piece and at points during the composition that demanded the most synchrony.
  • The synchrony was most prominent in the frontal and central parts of the brain that regulate motor function. "Whenever synchrony of behavior was high, synchrony of brain waves were also high,"
  • While brain synchrony during a duet seems like a given, it's a mystery how it happens, says Lindenberger, a psychologist. "One could speculate that this may be related to mirror neurons, the capacity of primates and humans to imagine the action of the other person while performing actions yourself," he says. "The mirror neuron system could be active during synchronized guitar playing."

    Credit their brain waves: they synchronize before and while musicians play a composition, according to new research.

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

dopamine neurons brain learning rewards behavior

  • 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.

  • If you're taking a test of rote memorization, like words from a list, move your eyes from side to side for about 30 seconds before you start.
  • It may be that this quick activity helps facilitate interaction between the brain hemispheres.
  • any activity that encourages communication between the hemispheres is likely to increase recall.
  • ...6 more annotations...
  • people who have poorer interactions between the hemispheres should benefit more than others. Who has less interactions between hemispheres? People who are strongly right-handed.
  • Strongly right-handed students remembered significantly more words if they moved their eyes compared to keeping their eyes still. Non-strongly-right-handed students (including left-handers) remembered the same number of words regardless of whether they moved their eyes before the test.
  • strongly right-handed students had significantly fewer false alarms after they moved their eyes back and forth. But for non-strongly-right-handed people, the reverse occurred; moving their eyes caused them to falsely remember more words. So overall, while the eye-saccade exercise helped right-handers, for lefties and for those who didn't have a strongly dominant hand, the exercise actually harmed their performance.
  • You might think that only side-to-side movement would improve performance, but Lyle's team found that moving your eyes up and down caused the same effect.
  • researchers say that other studies have shown that any eye movements increase bilateral activity in the frontal eye field, so it's still possible that hemispheric connectivity can explain the improved performance after eye movements.
  • So why doesn't the exercise work the same way for left-handers? Left handers (and ambidextrous individuals) already have a high level of hemispheric connectivity. Lyle's team speculates that there might be such a thing as too much connectivity, which results in a decrease in performance.
