Neural Circuits of Fair Play Discovered in the Human Brain

“Listen to your conscience,” my mother would say.But where does that mysterious urge to do what is right come from? Scientists have now pinpointed the brain circuitry that compels us to behave according to social norms; moreover, researchers can boost a person’s fairness by exciting this brain region, and promote cheating by inhibiting this bit of brain tissue.

Design a Brain Experiment Competition Is Back!

Now in it’s the third year, the Dana Foundation is once again calling on the future neuroscientists of America to submit their most creative brain experiment ideas to the “Design a Brain Experiment Competition.” Last year the number of submissions tripled and we received some great experiment ideas, topped off by the winning submission, “The Use of Acetylcholinesterase Inhibitors in the Treatment of Schizophrenia,” from Charltien Long of the Head-Royce School in Oakland, California.

A Conscious Dying Brain?

Following a car accident, a heart attack, or any other life-threatening event, there have been many instances documented where people that were near death, experienced something vivid, something that to them was real. Something that not only felt real, but for some, maybe even changed their lives. This might have been an interaction with deceased family members, a god they believe in, or something else.

Voluntary control over pupil size

There is a fascinating report in the levitra dosage and side effects Journal “Current Biology” that patient’s with “locked in syndrome” online cialis can communicate by pharmacy week controlling the size of their pupils. This raises a number of questions:

  • What is “locked in syndrome”? What can these patients do and not do?
  • What parts of the brain are necessary for consciousness and how are they affected by the locked in syndrome.
  • What are the mechanisms for brain control over the muscles that control pupil size and other muscles?
  • Is there conscious control online levitra over the Autonomic Nervous System?
  • Is there a relation to “biofeedback”? What is biofeedback?
  • What pathway from the cerebral hemispheres to the ANS could be responsible for conscious control of pupillary dilation?

Can a Parkinson’s Patient Ride a Bike?*

Three years ago the New England Journal of Medicine published a remarkable case study: “Cycling for Freezing Gait”. The report from doctors in the Netherlands describes a man with severe Parkinson’s disease who was virtually unable to walk, but, when put on a bike, rode beautifully, including the ability to turn, raise off the seat for power, and comfortably dismount. Continue reading
