Frequently asked questions

== Interactive images ==
Here, in the left, narrower part of the screen, is a row of images showing the nervous system and brain seen from different points of view. You select the image you want to examine by left-clicking on it or on its name.

You can then turn off and light the different parts of the image just as you want with the help of different headings and name lists.

In front of the headings and/or name lists, there is a box, which if "checked" (click with the left mouse button) activates the heading or name list. If a list of names contains multiple entries, it is preceded by an arrowhead (>). To open a list of names, click the arrow header. The arrowhead then rotates and points down (v), and the list has unfolded. At the top and bottom of the list you have the option to turn all the list names on or off. Note that this only works if the list has previously been enabled (the box before the list name must be "checked").

There are two list types here:

1/ lists related to the brain dissections (photographs). Here, boxes are missing in front of the structure names. If you point to a name in the list, the corresponding area/structure lights up (is colored) in the photo. The area/structure also lights up (is colored) when you point to it in the photo and its name is printed in the top black bar. If you click on the name in the list or on the illuminated part of the photo, a fact box will appear in the left column.
When you enter a new step, all marked/colored areas are shown for a moment and then disappear. This is a programming effect and can be experienced as disturbing, especially in Brain Dissection 4: "From top to bottom". If you want to avoid this disturbance, you do so that you directly and quickly click (arrow at the top right) through all the steps of the presentation and then in the last step with the help of the headings under "All steps", at the bottom of the left column, click on "Step 1" to calmly get through the presentation. 2/ lists in connection with the cartoon images. Each name in the list is preceded by a tickable box. If you check the box, the texture/color disappears in the image, if you check the box, the structure appears. If you point to a colored structure in the image, its name appears at the top of the frame's black bar.

By clicking on a name in the list or on part of the image, a current fact box will appear. You can return to the image list at any time and select a new image.

To move the image in the large screen field, click (left mouse button) on the arrows in the arrow cross that are at the top of the black bar.
You can also position the pointer anywhere in the large screen field, press the Alt key (the pointer changes to one hand), and hold it down while you move the pointer around with the mouse.
You change the magnification by clicking on the magnifying glasses that are up in the black bar. Plus = increase. Square = default.
You can also change the magnification (now in large increments) by right-clicking in the large screen field and then clicking "Zoom in" or "Zoom out" in the menu that appears in the large image field
A third variant is to place the pointer somewhere in the large screen field, hold down the Ctrl key (the pointer turns into a magnifying glass with + in it) and at the same time click with the left. mouse button. If you want to reduce instead, the Ctrl and Shift keys should be pressed simultaneously (- in the magnifying glass).

== 3-dimensional images ==
Here, as the first image in the large screen field, the entire brain is shown with transparent bark.

The narrower left screen bar shows a series of different brain sections - slicers from the first image. Here you choose the brain part you want to examine by clicking on the corresponding image!

Place the mouse cursor/cursor somewhere in the black area outside the colored/shaded brain part itself.
Press it in the left. mouse button and hold it while you slowly move the pointer up-and-down or back-and-forth on the screen. If you stop with the pointer but still hold the left button, the brain continues to rotate with the speed it had when you stopped.
Right-clicking in the image will bring up a menu where you can, among other things, choose the rotation speed (speed), the number of frames per time unit (preferences; frame rate) and, not to forget, choose the starting position for the rotation (viewpoints). The Viewpoints function does not work in the "first image" but otherwise.
It will be really good with low "speed" and high "frame rate" if you move the pointer really fast and then stop. Maximum "speed" is not bad either!
The menu's "Help" > "Users guide" provide an exhaustive instruction manual in English.

If the pointer is placed in the image, a name will appear and if you click on it, the corresponding fact box will appear in the left column.

The brain model is based on three series-sectioned, photographed and computer-reconstructed human brains.

== Encyclopedia ==
Here you can search for information directly using the first letter of the requested term (register). Or you can type the term name in the search box and press the "enter/return key" on your keyboard.
To the information text is (optionally) attached a series of thumbnails of the brain (on the right side of the screen). If the requested concept corresponds to a brain part, this is - sometimes - highlighted in the thumbnails (the function is under development).

Names marked in black in the register do not, so far, have a description.
