Why do neuroscientists study weird animals?: A primer on neuroethology
Why do neuroscientists study weird animals? And I don’t mean borderline weird; I mean the kind of extraordinary animals that can create electric fields and lift 100 times their body weight. The sort of animals that can camouflage despite being colorblind and can capture flying prey in fractions of a second. The kind of creatures […]
