Brain Memory

shared by isaac Mao on 28 Nov 08 - Cached
  • To remember a particular event, a specific sequence of neurons must fire at just the right time. For this to happen, neurons must be connected in a certain way by chemical junctions called synapses. But how they last over decades, given that proteins in the brain, including those that form synapses, are destroyed and replaced constantly, is a mystery.
  • Many genes are already coated with methyl groups. When a cell divides, this "cellular memory" is passed on and tells the new cell what type it is - a kidney cell, for example. Miller and Sweatt argue that in neurons, methyl groups also help to control the exact pattern of protein expression needed to maintain the synapses that make up memories.

brain iq learning memory

  • Most IQ tests attempt to measure two types of intelligence--crystallized and fluid intelligence. Crystallized intelligence draws on existing skills, knowledge and experiences to solve problems by accessing information from long-term memory. Fluid intelligence, on the other hand, draws on the ability to understand relationships between various concepts, independent of any previous knowledge or skills, to solve new problems. The research shows that this part of intelligence can be improved through memory training.

  • Only recently have scientists been able to learn how the neural network of the brain forms. Beginning in the womb and throughout life this vast network continues to expand, adapt, and learn.

  • Plasticity is the basic mental drive that networks your brain, giving you cognition and memory – fluidity, versatility, and adaptability.
  • Before birth you created neurons, the brain cells that communicate with each other, at the rate of 15 million per hour! When you emerged into the world, your 100 billion neurons were primed to organize themselves in response to your new environment – no matter the culture, climate, language, or lifestyle.
  • A healthy, well-functioning neuron can be directly linked to tens of thousands of other neurons,
  • A healthy, well-functioning neuron can be directly linked to tens of thousands of other neurons, creating a totality of more than a hundred trillion connections – each capable of performing 200 calculations per second!
  • Many neuroscientists believe that learning and memory involve changes at neuron-to-neuron synapses.
  • Travel is another good way to stimulate your brain. It worked for our ancestors, the early Homo sapiens. Their nomadic lifestyle provided a tremendous stimulation for their brains that led to the development of superior tools and survival skills. In comparison, the now-extinct Neanderthal was a species that for thousands of years apparently did not venture too far from their homes. (Maybe they were simply content with their lives – in contrast to the seldom-satisfied sapien.)
  • Exercise is a natural part of life, although these days we have to consciously include it in our daily routine. Biologically, it was part of survival, in the form of hunting and gathering or raising livestock and growing food. Historically, it was built into daily life, as regular hours of physical work or soldiering. What is now considered a form of exercise – walking –was originally a form of transportation.

  • Glucose metabolism naturally slows with age, and memory begins to decline in our 30s, says co-author Scott Small, an associate professor of neurology at Columbia University Medical Center in New York. The new study suggests a possible association between the two, because elevated blood sugar appears to damage the dentate gyrus, Small says.

  • Resilience is the ability to successfully manage life and adapt to stressful events. Resilience is developed in childhood, when there are loving people available to help during difficult times, but if a child feels alone, resilience is not developed just because challenging things are happening.
  • Due to recent brain research on neuroplasticity, we know that brains are growing and creating neural pathways during childhood and through adolescence. What's new in this book is the focus on a repetitive practice that strengthens these neural pathways and teaches young people concrete skills to calm themselves and focus their attention.
  • The interesting part of the connection between stress and learning is that the prefrontal cortex of the brain is the area for paying attention, calming, and focusing as well as the area for short- and long-term memory.

  • Also, when children are upset, nervous, or angry and cannot manage their distressing emotions, they are not in an optimal zone for learning and retrieving information. They may know something for the test, but they are not able to access it.
