<p>Top 20 schools who made the cut for Biology (based on the Gourman Rankings) are: </p>
<p>MIT, Caltech, UC Berkeley, Northwestern, Harvard, Princeton, Cornell, and Penn. </p>
<p>To comment further on Penn, just because I go there and am familiar with it:</p>
<p>You can see more about the Penn major here

<p>and research opportunities for undergrads (there are a lot, as Penn is a huge research university and has the Hospital right on campus) here: <a href="http://psych.upenn.edu/%7Esschill/ra.html%5B/url%5D">http://psych.upenn.edu/~sschill/ra.html</a></p>
<p>Wherever you side to go, make sure there are ample research opportunities, as that's pretty much what you'll be doing with interests in Cog Sci.</p>
