Well, unfortunately I don't have a brain sitting here, so I can't pull the lobes apart and poke at the corpus callosum (which connects the hemispheres), but I can talk about the different lobes! Frontal lobe - the largest of the lobes in the brain. This part of the brain is responsible for "higher order" functions. Much of conscious thought has it's roots here. There are also sectors of the brain here that help suppress inappropriate behavior. Planning movement also occurs in this lobe (and many other places as well) Parietal lobe - this is often called the association lobe. The primary sensory cortex is here, so all the feelings from your skin make their way to this lobe. There's also parts here that help you integrate information related to the senses into thought. Vision and sound information (among others) make their way here after they are received in their primary areas. Occpital lobe - this is the visual lobe. A large majority of the part of this lobe is dedicated to handling the incredible amount of information coming from the eyes. Temporal lobe - this lobe is where smell and sound come into the brain. There's a part of this lobe that helps with language. This brain also helps integrate visual information into thought. The centers for short term memories often lie here as well. As science learns more about the function of different parts of the brain, these definitions are likely to change, but for now they're a good introduction to neuroanatomy! --SP
