      The brain has two halves (hemispheres) and each hemisphere has lots of different parts, the outer layer (cortex) is split in to different lobes whose functions are indicated by their name: auditory (hearing), occipital (vision), motor (movement). Deeper inside the brain is the hippocampus, involved in memory and emotions (which are linked closely, as emotions are very similar to memory). And then there are very small key controllers deep in your brain like the pons, amygdala, thalamus, hypothalamus – important in processing information.

      However, we can split each region in to different areas again, I don’t know much about this detail, but scientists are still trying to figure out all the different types of cells in these regions involved in the input and outputs to/from them. It’s much like an electrical circuit, signals are sent around the brain through loads of circuits and we’re trying to piece together what goes where and why!
