Oh! I love this idea.
Hello, my lovely fellow science nerds.

I'm Liz, a third-year neuroscience & behavioral biology student. I'm studying to be a doctor--not sure which sort yet, but what with my being in love with brains and all I'll probably be in for neurology.
My favorite scientist? Galileo, not only for being the father of science as we know it but for having the strength of his convictions. Santiago Ramon y Cajal, for discovering the neuron, becoming sure that it was immutable, and then daring to hope that we'd one day figure out that was not the case. (“As long as our brain is a mystery, the universe, the reflection of the structure of the brain will also be a mystery.”) My favorite living scientists include Antonio Damasio and Richard Davidson, as well as Paul Ekman and Alan Wallace. Amazing stuff.
Edit: omggggg I nearly forgot Donald Hebb! D:
