The Top 10 Challenges for Brain Science in 2013 - Forbes - 0 views

shared by David McGavock on 31 Dec 12 - No Cached
  • 1. Figure out what fMRI can truly tell us about our brains. 
  • There’s little question fMRI is valuable, but too many disparate forces are out there spinning brain scans in too many ways. Perhaps one solution, or start of a solution, is a summit hosted by a credible, well-respected institute or organization to gather the best of the best minds in the field to establish a game plan moving forward.
  • 2. Determine what role, if any, neuroscience should play in the courtroom.
  • ...12 more annotations...
  • . Continue crafting a constructive consilience between disciplines.
  • Neuroscience, behavioral science, evolutionary biology, economics, engineering, and even the humanities have all come to the proverbial table in the last few years
  • Produce more applicable knowledge and less curious meanderings.
  • 7. Join forces with more public health sources to engender broader awareness of critical issues. 
  • Again, what is truly “solid applicable knowledge” is frequently debatable (see #1 above), but every year the field–and by that I mean the interdisciplinary field (#3)–has more to offer the public.
  • How about we spend more time trying to solve the problems and less time concocting clever catch phrases?
  • Shine the light on how far the forces of marketing have exploited brain science advances (this is a genuine public service).
  • I am an unwavering advocate of making sure people understand how the forces of marketing are using the field to sell more products.
  • Try to fight the urge to spin off more headline pablum like “Brain Porn.”
  • 8. Put the brakes on “building a brain” — we already have plenty of them.
  • in my opinion we have enough to do with respect to figuring our how our organic brain works without spending massive resources on trying to recreate one.
  • 9. Turn the corner from “what’s wrong with our brains” to “what we can really do about it.”

    Using a simple True/False Learning Styles questionnaire(like this, see below), researchers found that people could reliably predict whether they are predominantly visual or verbal learners.

  • There was no real difference between the early birds and the night owls in their performance on the morning test. But the evening test was a different story: night owls were less sleepy and had faster reaction times than early birds.
  • So even though both groups were sleeping and waking according to their preferred schedule, night owls generally outlasted early birds in how long they could stay awake and mentally alert before becoming mentally fatigued. The fMRI supported the behavioral results: 10.5 hours after waking up, the early birds had lower activity in brain regions linked to attention and the circadian master clock, compared to night owls.

    A new study, in the journal Science, reports some intriguing differences between the brain-activity patterns of the two types that underlie the behavioral differences.

neurophilosophy brain LTP learning memory

shared by Tero Toivanen on 23 May 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.
