ESR6 : Spatial maps in bats under visual and echolocation control

Supervisors: Nachum Ulanovsky and Misha Tsodyks

This position has been filled.

This project is in collaboration with SISSA. The hippocampus can encode multiple representations of the same spatial context, when different cues are available. This can be demonstrated in a powerful way in flying bats, which use both vision and echolocation. Spatial maps appear orthogonalised between vision and echolocation. We will extend these experiments by gradually changing the light levels, and observe the transition between vision- and echolocation-related regimes, to see whether it is a graded or abrupt one and whether the two regimes may coexist or show hysteresis.

The data will be analyzed based on SISSA’s expertise from previous work with NTNU, and used for theoretical models by other partners in M-GATE.
