  1. How the brain works 2003-03-27 - 15:30 - 16:30 [Workshop, Bio]Presenter: Dr. Martin Lindner-Effland (Ministry of Education, Kiel, Germany)New experiments dealing with recent scientific results about the function of the human brain will be shared. Most of these experiments are easy to do and some are computer aided.

  2. Themes • 90th as the decade of the brain • Biology, Psychology, Medicine, Mathmatics and Philosophy meets in search for the explanation of the brain´s function.

  3. Foreview (Content) • 1. How to get knowledge about anatomy and function of the brain • 2. Motor learning: a bow from exciting experiments to the cellular anatomy of the brain • 3. The Working memory-Concept - what psychology teaches about memory

  4. 1. How to get knowledge about construction and function of the brain 1. Anatomic section of a pig´s brain 2. A simple Method of getting micro-preparates for first investigations on brain cells 3. Modern methods to gain knowledge about form and function of brain cells 4. The view into the brain by methods of computer-tomography 5. How to show electric activity of the human´s body - e.g. how fast are our nerves?

  5. Anatomic section of a pig´s brain

  6. Examine the Brain

  7. A simple Method of getting micro-preparates for first investigations on brain cells Methylen-blue 10 Minutes Pyramidal cell From Cerebellum Smaller cells Glia cells

  8. Modern methods gain knowledge about form and function of brain cells

  9. The view into the brain by computer- tomography

  10. How to show electric activity of the human´s body

  11. Motor learning Explanation Cellular Structure of the Brain Experiment

  12. Motor learning: • Phenomenon • Interpetation of the phenomenon by a simple reflex-model • Organic deseases supressing the phenomenon • Architecture of the cerebellum • Function of the cerebellum-cells in an animal-model • Explanation on a cytologic level

  13. What do we observe?

  14. Interpretation by a simple reflex-model

  15. Architecture of the cerebellum

  16. Function of the cerebellum-cells in a animal-model

  17. Explanation on a cytologic level

  18. The concept of working memory - what psychology teaches about memory function

  19. Experiments 1. Demonstration of two pictures with faces - what do you remember? 2. Demonstration of different numbers of objekts - how many do you remember? 3. Remember a list of 10 syllables - with and without a following mathmatical exercise. 4. Remember the phone-number or the number of your account: the evidence of chunking. 5. Mental rotation - how fast is your brain?

  20. Results Existing Memory is checked in less than 1 second Limitation to 7-5 items Enlarge this contens by chunking Memory is troubeled through additional tasks Mental processes take time

  21. The working memory - Concept(BADDELEY) Input Central Executiv Phonological loop Visual scratch-pad Working Memory Memory
