The Art Of The Brain

1. Cajal’s labyrinth of the inner ear, which contains the sensory structures for hearing and balance.

2. Cajal summarizes many of the properties of astrocytes in this drawing of the hippocampus of a man three hours after death.

3. Here we see damaged Purkinje neurons of the cerebellum. Cajal has chosen to focus on the cell bodies, which have a bloated, empty appearance. The most swollen of these cells (G) has the appearance of a penguin, swimming among the other neurons. Did Cajal actually see a penguin as he gazed into his microscope? Hard to tell, as Cajal typically drew from memory.
