Visual tasting. Center the image using the "arrow cross" in the top black strip! This series of images includes one starting stage and four working steps. The series shows a punched-out square area (a so-called cuboid) of the cerebellum. The punched out part comprises a layer of cerebellar cortex - here called the "bark prism" - and underlying white matter with a schematically inlaid core accumulation (the blue "egg"). It is important that you place and move the image around as you want it on the screen and that you use different magnifications (Help) . Do not forget about the identification function

Step 1.

Bark prism with white matter and core accumulation. The photo shows the outline of the punched cuboid block. The upper surface of the figure corresponds, in reality, to approx. 0.8 square millimeters of the small brain's total area of approx. 200,000 square-millimeters; Covered by Pia. Check the boxes in turn. Start with list 1, unfold it, "turn it off" and tick it from bottom to top! Do not forget to combine different image parts in ways that you find interesting! The Purkinje cells, which fill out the outer parts of the cerebellar cortex, are schematically depicted as seven-armed candlesticks (dendrites) with a round foot (cell body) and a thin axon wire to the nuclear accumulation. Cf. with "The Little Brain Cortex 1". The Purkinje cells are arranged in longitudinal (here 10 pcs.) and transverse rows (here 13 pcs.).

Step 2.

Bark prism with neurons and signal inflow. This is a step that requires movements and different degrees of strength! Examine lists 1 and 2 with "Mark out the ten Purkinjecell trails" alternately lit and alternately extinguished! Bark cells with excitatory action on the Purkinje cells are greenish, those with inhibitory action are reddish . NB. that the Purkinje cells that are inhibitory are black when they appear in the picture! Notice that the basket cells, Lugaro cells and star cells are oriented in harmony with the Purkinje cells. These cells are only marked in connection with the 1st limb Pukinje cells. The Golgi cells, on the other hand, spread out their dendrites and their extensive axon branches over several Purkinje cell joints. The 18 grain cells from step 1 are not affected here in step 2 by markings in list 1 below! The picture is complicated and slowly reacts to commands!

Step 3.

The reaction of the bark prism to the inflow of moss wire signals. Here, the target cells of the moss threads (two groups of grain cells) are already in place in the 1st Purkinje cell joint. The purpose of the picture is to give you an idea of the effects that moss wire signaling into the cerebellar cortex has. Tick the boxes in turn from top to bottom!! Note that four groups of grain cells are activated when 2/ is ticked and not just the two groups that are already in place when the step is opened. To repeat: Go back to Step 2 and then go up to Step 3 again. It's much easier than unchecking all the levels in step 3 and then restarting from scratch. The picture is complicated and slowly reacts to commands!

Step 4.

The reaction of the bark prism to the influx of climbing wire signals. The purpose of the picture is to give you an idea of the effects that the climbing wire signal ring into the cerebellar cortex has.
