Would that be a bad thing?</p> <p>16Does this mean:</p> <p>at any given time only 10% is active if so, what qualifies as active</p> <p>90% of your brain (anatomically) is blank or untapped resourceif so, does it fill up?</p> <p>90% of your mental capacity is unused?</p> <p>The Methods of Cognitive NeuroscienceHow many of you have heard the statement that you only use 10% of your brain?</p> <p>What do you suppose this means?

How could you know?17How could you know?</p> <p>Anatomical:</p> <p>Lesion studies - parts of the brain are removed or damaged in animals and people and there is almost always a loss of function-but that functional loss can be quite minimal and detectible with only the most sensitive of tests-doesnt really allow a one-to-one mapping of function onto structure</p> <p>PET, fMRI, electrical recordings can capture activation of brain tissue due to cognitive function-limitations of these techniques are substantial, they dont detect all brain activity!-you can only really proceed by throwing tasks at the brain and seeing what areas dont light up</p> <p>Capacity sense:</p> <p>Its hard to know what 100% capacity is if no-one ever acheives it!</p> <p>Engineering approach:</p> <p>You could measure the total energy output of a single active neuron, multiply by the number of neurons, then measure the heat output of the entire brain and subtract.</p> <p>W = V I = .007 V x .000000003 A = .00000000002 WW(total) = .00000000002 x 1000000000 = .021 W10% of that is .0021 W</p> <p>Brain uses ~10% of bodys energy = ~10 W!The Methods of Cognitive NeuroscienceNext time: Goals and Techniques18How could you know?</p> <p>Anatomical:</p> <p>Lesion studies - parts of the brain are removed or damaged in animals and people and there is almost always a loss of function-but that functional loss can be quite minimal and detectible with only the most sensitive of tests-doesnt really allow a one-to-one mapping of function onto structure</p> <p>PET, fMRI, electrical recordings can capture activation of brain tissue due to cognitive function-limitations of these techniques are substantial, they dont detect all brain activity!-you can only really proceed by throwing tasks at the brain and seeing what areas dont light up</p> <p>Capacity sense:</p> <p>Its hard to know what 100% capacity is if no-one ever acheives it!</p> <p>Engineering approach:</p> <p>You could measure the total energy output of a single active neuron, multiply by the number of neurons, then measure the heat output of the entire brain and subtract.</p> <p>W = V I = .007 V x .000000003 A = .00000000002 WW(total) = .00000000002 x 1000000000 = .021 W10% of that is .0021 W</p> <p>Brain uses ~10% of bodys energy = ~10 W!Your final Letter grade will be calculated as follows: </p> <p>PercentageLetter Grade</p> <p>90-100A+</p> <p>84-89A</p> <p>80-83A-</p> <p>77-79B+</p> <p>73-76B</p> <p>70-72B-</p> <p>67-69C+</p> <p>63-66C</p> <p>60-62C-</p> <p>55-59D+</p> <p>50-54D</p>
