Are the Lobes the Only Parts of the brain?

No! There are many parts of the brain. We start the BrainReach year by describing the 4 lobes of the brain, as well as the cerebellum and brainstem. However, if we were to slice the brain in half lengthwise, we would see many other structures that are deep inside the brain. For example, you would see the corpus callosum (which connects the left and right hemisphere of the brain), and structures of the limbic system (involved in emotions, learning and memory). Every single part of the brain is connected. For example, injuring a part of the limbic system can impact connections it has with the frontal lobe.
