Anatomical drawings (schemes)

We need two tasks for this project. I have attached a Powerpoint file Task 1. We need a drawing for publication about what is called evoked potentials or electrical signals recorded from the brain structures when sensitive stimulus is provided. We need four color individual drawings (brain + 3 slices) that has to be connected by lines in a very specific way. I have attached some examples of the slices that has to be modified because the originals are from internet and [login to view URL] the drawings cannot be difficult it is crucial that lines are precisely drawn to represent what we need and we expect to ask for a few modifications in the drawing (lines) before we decide is completed Task 2. This is quite simple. We had already one drawing did by a coder in Ai format. We need to modify the lines and add another pathway (green one). Although the drawings cannot be difficult it is crucial that lines are precisely drawn to represent what we need and we expect to ask for a few modifications in the drawing (lines) before we decide the task is completed. In the slide labeled task 2 we have an image on the left (availabe in AI file) and on the right a sketch of what we need to be done. The cider will be provided with the original AI file for this task. Both drawings need to be delivered in Adobe Illustrator file format and need to render fine both in color an grayscale and in high resolution for printing.
