• ?• ??• ???• Many unsolved problems: Language,
consiousness
Simplification in the world of text processing: Reading imbedded in sensorimotor actions
Question: what happens in the brain „behind the eye“during reading ?

Copy-Paste between a Pdf-file and a Powerpoint slide: Instructions
1. Click on the Adobe buttom. Go to the page containing Figure 1. Enlarge the image, by clicking on the arrow on the right of the white window and selecting 100%. Center the image.
2. Click on ‚Werkzeuge‘ on the second Adobe control bar. Move to ‚Auswählen und Zoomen‘ and follow the arrow into the context window down to ‚Schnappschuss-Werkzeug‘.
3. Move the cross of the pointer to the left upper corner of Figure 1. Press the left mouse buttom, move it to the right lower corner and let go.
4. Change to Powerpoint,by clicking on its control buttom. Point into the slide and type ‚Ctrl+V‘. Click into Figure 1 and center it in the content field. Type ‚Architecture of the FEF model‘ in the title field.
5. Click on ‚Neue Folie‘. Move to Adobe Click on the ‚Single Page‘ button on the upper control bar and go to the page containing Figure 2. Repeat the same steps, without having to change again into the ‚Schnappschuss-Werkzeug‘.

Nur jedem das Seine (BWV 163)
Nur jedem das Seine! Muss Obrigkeit haben Zoll, Steuern und Gaben, Man weigre sich nicht Der schuldigen Pflicht! Doch bleibet das Herze dem Höchsten alleine.

Gott soll allein mein Herze haben (BWV 169)
Stirb in mir, Welt und alle deine Liebe, Dass die Brust Sich auf Erden für und für In der Liebe Gottes übe; Stirb in mir, Hoffahrt, Reichtum, Augenlust, Ihr verworfnen Fleischestriebe!
