| summary | The work in our lab focuses on understanding the neural basis of
spatial memory and spatial cognition – using bats as our animal model.
In my talk I will present some of our recent studies, which explored
the following questions: (i) How does the brain represent positions
and directions in 3D ? A set of studies revealed 3D place cells and 3D
head-directions cells in the bat hippocampal formation. (ii) How are
navigational goals represented in the brain ? We discovered a new kind
of vectorial representation of spatial goals – whereby hippocampal
neurons encode the direction and distance to a spatial goal. (iii) I
will describe our very recent discovery of “social place-cells” in the
bat hippocampus – neurons that represent the position of other bats
(conspecifics). (iv) Finally, I will describe ongoing work towards
elucidating hippocampal neural codes in realistic, kilometer-scale
environments – where we discovered an unexpected multi-scale coding of
space. Our long-term vision is to develop a “Natural Neuroscience“
approach for studying the neural basis of behavior – tapping into the
animal's natural behaviors in complex, large-scale, naturalistic
settings. |
