Tracing the formation of long-term memory
December 07, 2006The formation of long-term memory in fruit flies can be demonstrated by the influx of calcium into cells called mushroom body neurons that occurs after special training that includes periods of rest, said researchers from Baylor College of Medicine (BCM) in a report that appears in the current issue of the journal Neuron.
"We have strong evidence that this is really a molecular change that is involved in long-term memory," said Dr. Ronald Davis, professor of molecular and cellular biology at BCM. "This appears to be an authentic memory trace for long-term memory."
Davis and his colleagues used spaced training to teach the flies to associate an odor with a mild electric shock. This method gives the fly a training trial, then a rest and then another trial. The rest is critical in inducing long-term memory that can last days. In this study, the five spaced trials produced a memory that lasted for more than a day. They then used a technique called "functional imaging" to see when the memory formed in the fly's brain.
"Before training, we could see some calcium flowing into the mushroom body neurons when the flies were exposed to odor," said Davis. When they exposed the fruit flies or Drosophila to the odor 24 hours after spaced training, they saw much more calcium flowing into the mushroom body neurons. The increased calcium influx paralleled the long-term memory of the flies. Using special laboratory techniques, he and others in the lab showed that they could block the calcium influx by blocking the function of a protein critical to making the new synapses associated with long-term memory.

This is your brain on fatty acids
Saturated fats have a deservedly bad reputation, but Johns Hopkins scientists have discovered that a sticky lipid occurring naturally at high levels in the brain may help us memorize grandma's recipe for cinnamon buns, as well as recall how, decades ago, she served them up steaming from the oven.
Why one way of learning is better than another
A new study from the Montreal Neurological Institute and Hospital (The Neuro) of McGill University reveals that different patterns of training and learning lead to different types of memory formation.

Is there long-term brain damage after bypass surgery? More evidence puts the blame on heart disease
Brain scientists and cardiac surgeons at Johns Hopkins have evidence from 227 heart bypass surgery patients that long-term memory losses and cognitive problems they experience are due to the underlying coronary artery disease itself and not ill after-effects from having used a heart-lung machine.

Brain Based Teaching: Making Connections for Long-Term Memory and Recall by Dr. Robert K. Greenleaf (Author) "Brain Based Teaching: Making Connections for Long-Term Memory and Recall" seeks to explore teaching and learning through three overarching lenses: Question #1 - How can I "frame" (design) the learning circumstance or activity so that it INVITES ALL learners to get involved, to participate? Question #2 - How can I design the learning experience such that it will CAUSE learners to process, to do the work required for sustained learning and recall to take place? Question #3 - How do I engineer tasks that create opportunities for multiple PATHWAYS to be formed (connections made) for integrated learning, applications and recall? Brain research, though historically focused on abnormalities and pharmaceuticals, has evidenced levels of attention in education and learning endeavors. We have come... |

Native Remedies MemoRise for Short and Long Term Memory Loss by Native Remedies As we grow older, we sometimes begin to notice that our memories are not as good as they used to be. Fall off of cognitive functioning, including memory, can begin from as young as the mid-thirties and is greatly affected by genetic makeup, stress and other health-related factors such as diet, exercise and lifestyle. It has also been discovered that the more active we are mentally, the better our minds work for all age groups. A healthy lifestyle can help keep the mind functioning at its peak by eating lots of fresh fruit and vegetables and whole grain foods, getting plenty of fresh air and sunshine and exercising regularly. Avoid smoking, excessive alcohol intake and other drugs. MemoRise is a 100% natural remedy that has been scientifically shown to improve memory loss linked to aging... |
