Unfortunately, we don't have photomicrographs at each magnification for every animal. However, we can start to see similarities between the neurons in many of these pictures...

In some cases, at the same magnification, the neurons of each animal look very similar and even identical. Why, then, do you suppose these animals behave in different ways if even the neurons look similar? If the building block of the brain (the neuron) is the same in every type of animal's brain, why don't all animals act the same????

No one has a true or certain answer to that question. However, often people generalize that one must look at the larger picture to get an answer. Others argue that more needs to be known about the neurons in particular. What do you think? Do we learn more by looking at the larger-scale structures of the brain or studying each individual neuron?? Learn more about neurons by clicking on the button below...

I want to learn more about neurons!!!

Huh? Can we start over?
