Now we are looking at a cross-section of the hindbrain of a rat.

Can you tell what structure this is? Do you see the convoluted material that is dark purple? That is the cerebellum. What other structures do you see? What is beneath the cerebellum? Although it is difficult to tell exactly what level we are seeing, structures of the brainstem may be apparent. Do you remember what structures constitute the brainstem? It includes the pons, medulla oblongata, and spinal cord.

Now we are looking at a cross-section of the forebrain of a rat.

As with the human, monkey, and cat forebrains, this image is a good illustration of the cerebral cortex at the frontal lobe of the brain. The dark purple that looks like an outline is gray matter. The light purple inside the dark purple is white matter. You can also see the body of the corpus callosum, which is the structure connecting the two hemispheres of the brain. The white elliptical openings within the brain are ventricles, which are fluid-filled cavities that serve to cushion and protect the brain. You can also see midbrain structures in this image. What else do you notice about this image?

Now we are looking at a cross-section of the hindbrain of a cat.

Follow these steps to add your image to your post:

1. Create a new Post or Faculty Group Post if you have not already done so
2. Below the Body area, there is an area called Insert an Image
3. Click Browse, find the image file on your computer, then click Upload. After the file is uploaded, you will see a small (thumbnail) version of the image appear in the Insert an Image area.
4. Move the cursor to where you want the insert to happen in the Body area, and click there.
5. Click Insert in the Insert an Image area, and the image will be inserted in the Body area.

By default, what you will get is:

• a 350 pixel wide version of your image
• aligned left, with text wrapped on the right
• with 20 pixels of white space around it.

You can upload as many images as you like and insert them in this way.

You can resize them in the Body editing box by click-dragging on a corner of the image.

More Automatic Sizes Available

Before you click Insert (step 5 above), you have the option of selecting a different size to insert. It is a pulldown called Style, next to the Insert button, and the numbers in it are the width in pixels that you want (there are also words like small, medium, xlarge to help).
