01/09/2022 The paper "Natural switches in behaviour rapidly modulate hippocampal coding" is published in Nature.
The study, led by Ph.D students Ayelet Sarel and Shaked Palgi, asked how rapid switches in natural behaviors modulate hippocampal coding. Pairs of bats flew in a long tunnel, switching between navigation and collision-avoidance. Hippocampal neurons switched very rapidly from representing the animal’s own position when flying alone, to jointly representing the inter-bat distance x self-position when encountering another bat. Thus, hippocampal circuits are highly flexible and can rapidly change their core computation – to represent the relevant behavioral variable.

19/08/2021 Paper on locally-ordered 3D grid cells is published in Nature.
The study, led by Ph.D student Gily Ginosar, showed that 3D grid cells in flying bats exhibit fixed local distances between firing-fields -- a local metric for space -- but no hexagonal global lattice as predicted theoretically. We modeled grid cells as emerging from pairwise-interactions between fields, yielding hexagonal lattices in 2D but local order in 3D -- thus describing both 3D and 2D grid cells using one unifying model. These results argue against grid-cell models that rely on lattice-like periodicity.
 
28/05/2021 Paper on multiscale representation of very large environments is published in Science.
The study, led by Ph.D students Tamir Eliav and Shir Maimon, demonstrated a novel spatial code for very large environments. Using a wireless-electrophysiology system, we recorded hippocampus CA1 neurons of bats flying in a 200-meter long tunnel, and found a multifield multiscale code - whereby neurons exhibited multiple fields, and the fields of the same neuron differend up to 20-fold in size. A theoretical analysis showed that such a multiscale code dramatically reduces the decoding-errors.

07/11/2018 Nachum Ulanovsky wins the Kimmel Award for Innovative Investigation - with a 1M$ Research Prize.
01/11/2018 Paper on nonoscillatory phase-coding and synchronization is published in Cell.
The study, led by Ph.D student Tamir Eliav, demonstrated that hippocampal neurons encode the animal's position through temporal-coding (phase coding), in the absence of the theta oscillations observed in rodents. This unexpected type of neural coding - nonoscillatory phase-coding - dissociates the concept of phase-coding from the concept of oscillations; and it shows that coding but not oacillations is conserved across species (rodents, bats, and possibly primates).
12/07/2018 Nature published today a News Feature about the bat-lab and about Nachum - as well as a Video Interview with Nachum about the work done in the lab and the future vision for Natural Neuroscience.

12/01/2018 Paper on social place-cells in the bat hippocampus is published in Science.
The study, led by postdoc David Omer, describes the discovery of hippocampal neurons in bats that represent the spatial position of a conspecific bat, in allocentric coordinates. The representation of the other was very different for a live bat than for inanimate moving objects. We tremed these neurons "social place-cells", and proposed they may underlie social-spatial cognition in bats and other mammals.

07/11/2017 Nachum Ulanovsky wins the Andre Deloro Prize - from the Adelis Foundation.
13/01/2017 Paper on vectorial representation of spatial goals in the hippocampus of bats is published in Science.
The study, led by Ph.D student Ayelet Sarel, describes the discovery of hippocampal neurons in bats that represent the direction and distance to goals - a vectorial representation of navitational goals. This finding fills a central gap in the neurobiology of navigation - how are navigational goals represnted in the brain: We propose that these vectorial goal-direction and goal-distance cells may underlie goal-directed navigation across species.
15/11/2016 Ayelet Sarel wins the prestigious Boehringer Ingelheim Fonds Ph.D fellowship.  
Congratulations, Ayelet !
01/08/2016 Two papers from the lab are published in Annual Reviews of Neuroscience and in Nature Neuroscience.
The review in Annu Rev Neurosci, led by Ph.D student Arseny Finkelstein, discusses 3-D maps and compasses in the brain - focusing on the hippocampal formation of rodents and bats.   The study in Nature Neurosci, led by Ph.D student Maya Geva-Sagiv, was titled "Hippocampal global remapping for different sensory modalities in flying bats", and it demonstrated orthogonal hippocampal maps for the same space under two different sensory systems (vision vs. echolocation) - which argues against a hippocampal abstract map but suggests a "cognitive atlas" model.

22/01/2015 Review on the neural basis of spatial cognition in bats and rats is published in Nature Reviews Neuroscience.
The review, led by Ph.D student Maya Geva-Sagiv, describes the proposed transformations from incoming sensory information into spatial codes (place cells, grid cells, etc.), and how these cells in turn could underlie large-scale navigation. The review emphasizes the critical need to study the neural basis of long-distance natural navigation in mammals - which could be quite different from findings in 1x1-m boxes.
08/01/2015 Paper on 3D head-direction cells in bats is published a a full Article in Nature.
The study, led by Ph.D student Arseny Finkelstein, describes the first recordings of 3D head-direction cells in mammals. Surprisingly, head-direction was encoded in a toroidal rather than spherical coordinate system, making the representation of 3D head-direction both commutative and continuous. These neurons form a 3D neural compass that could underlie 3D navigation

The study, led by Ph.D student Michael Yartsev, provided the first direct demonstration of grid cells in a non-rodent mammalian species. Importantly, grid cells existed in bats without continuous theta oscillations in the local field potential or in spike trains - strongly arguing against theta-based computational models of grid cells.
