In 1944 in an issue of Science, he proposed the term «
echolocation» to cover not only «locating obstacles by means of echoes» in bats, but also by people, including
via radar, fathometers and submarines using «apparatus working on the same basic principles.»
Hippocampal representations remapped between vision and
echolocation via two kinds of remapping: subiculum neurons turned on or off, while CA1 neurons shifted their place fields.
