About the cover
February 2007 Volume 10 No 2

Bats use echolocation to navigate and find food. Ulanovsky and colleagues now show that the bat
hippocampus contains 'place' cells and exhibits ripple and theta oscillations, known to characterize the rodent hippocampus. The cover shows a big brown bat, the species studied in the paper, with a moth in its mouth. Superimposed is a spectrogram of an echolocation call.
