Inline skating requires the acquisition of motor control and learning essay, coordination, planning and balance skills, but it is a sport that can be practiced just about anywhere.
In a new study, researchers pinpoint the brainwave frequencies and brain region associated with sleep-enhanced learning of a sequential finger tapping task akin to typing, or playing piano. How does sleep make that difference?
A new study helps to explain what happens in your brain during those fateful, restful hours when motor learning takes hold. We were trying to figure out the specific role of sleep.
The task was a sequence of key punches that is cognitively akin to typing or playing the piano. Here graduate student Aaron Berard models the cap.
Specifically, the results of complex experiments performed at Massachusetts General Hospital and then analyzed at Brown show that the improved speed and accuracy volunteers showed on the task after a few hours sleep was significantly associated with changes in fast-sigma and delta brainwave oscillations in their supplementary motor area SMAa region on the top-middle of the brain.
These specific brainwave changes in the SMA occurred during a particular phase of sleep known as "slow-wave" sleep.
The extent of reorganization that the brain accomplishes during sleep is suggested by the distinct roles the two brainwave oscillations appear to play. Meticulous measurements Possible roles for fast-sigma and delta brainwaves and for the SMA had suggestive support in the literature before this study, but no one had obtained much proof in part because doing so requires a complex experimental protocol.
To make their findings, Sasaki, Tamaki and their team asked each of their 15 subjects to volunteer for the motor learning experiments. For the first three nights, nine subjects simply slept at whatever their preferred bedtime was while their brains were scanned both with magnetoencephalography MEGwhich measures the oscillations with precise timing, and polysomnography, which keeps track of sleep phase.
By this time the researchers had good baseline measurements of their brain activity and subjects had become accustomed to sleeping in the lab. On day 4, the subjects learned the finger-tapping task on their non-dominant hand to purposely make it harder to learn.
Then the researchers woke them up. An hour later they asked the subjects to perform the tapping task. As a control, six other subjects did not sleep after learning the task, but were also asked to perform it four hours after being trained. Those who slept did the task faster and more accurately than those who did not.
Sasaki said she expected the most significant activity to take place in the "M1" brain region, which governs motor control, but instead the significant changes occurred in the SMA on the opposite side of the trained hand. What was especially important about the delta and fast-sigma oscillations was that they fit two key criteria with statistical significance: After performing the experiments, the team of Sasaki, Tamaki and co-author Takeo Watanabe moved from MGH to Brown, where they have set up a new sleep lab.
They have since begun a project to further study how the brain consolidates learning. The National Institutes of Health grants:Ericsson Paper: Motor Learning 03/08/97 The main point in Ericsson et.

In this paper we present theoretical and operational perspectives on the functions of motor learning with refer- ence to sport skills. The data available on this issue are largely from non-sport motor skills but inferences are drawn to the.
Motor Learning essaysFor my new motor skill I chose inline skating. Inline skating requires the acquisition of motor, coordination, planning and balance skills, but it is a sport that can be practiced just about anywhere.
I chose to dedicate about 1 to 2 hours per day to mastering this sport. Welcome to a set of courses and other learning material provided by Ericsson.
|Essay, term paper, research paper: Science Reports||Ericsson and his colleagues have taken the position that the major influence in the acquisition of expert performance is the confidence and motivation to persist in deliberate practice for a minimum of 10 years.|
|Deliberate practice for golf||Mr Gladwell has created a perception that expert performance is achievable after 10, hours of practice, which I believe to be untrue.|
