For example, let's talk about the two of us. There's my brain on the left. Is it different from yours? How would we know? We're in the same species, I assume. Does that mean our brains will look the same??
Most people assume that different animals have different structures and functions of brains. From where does that assumption arise? Well, different animals behave differently, so we can assume that their different brains are partly responsible for those behavioral differences. (Go here for more discussion about inter-species comparisons)
Okay, what about us? We're both humans . . . so we act the same, right? We both love and work and smile and scratch our itches. We both yawn when we're sleepy and, in the mornings, we both probably hit the snooze button as long as we can. Do you think that means our brains look the same? Does your brain function the same as your sister's? Does your grand-mother's brain have the same structure as your brother's?
Wow- what interesting questions. Keep that curiosity in mind as you go through this site . . . Think about how you and I are alike or different . . . Think about how you are different from your grandfather and aunt and cousin and brother. Let's explore whether the behavioral differences we see within our own species are associated with brain differences.
This site is organized into four main sections, where we will look at questions such as:
