- description: |
- The cerebellum contributes to spatial coding in the hippocampus.
- When PKC-dependent mechanisms are impaired in cerebellar Purkinje cells,
- hippocampal place cells indeed lose their spatial selectivity in the dark,
- when the animal relies mostly on self-motion cues to navigate.
- This impairment in PKC-dependent cerebellar functions additionally
- leads to behavioral deficits in using both external and self-motion
- cues when learning a goal-oriented navigation task. However, it is
- unclear how cerebellum influences the exploration strategy used by
- an animal during free foraging in an open environment.
- Here we recorded hippocampal place cells in mice with impaired PKC-dependent
- mechanisms (L7-PKCI) and in their littermate controls while they performed a
- foraging task where they were rewarded for visiting a subset of
- hidden locations. We found that L7-PKCI and control mice developed different
- foraging strategies: while control mice repeated reliable spatial sequences
- to maximize their rewards, L7-PKCI mice persisted to use a random foraging
- strategy. The sequence-based strategy was associated with more place cells
- exhibiting theta-phase precession and theta modulation. It was also correlated
- with a larger fraction of place cells that were modulated concomitantly by
- movement direction and speed. Finally, in the dark, the modulation of place
- cells by movement direction was markedly reduced in L7-PKCI mice, demonstrating
- that PKC-dependent cerebellar functions control how self-motion cues influence
- not only position but also direction coding in the hippocampus. Thus, the cerebellum
- contributes to the development of optimal sequential paths during foraging,
- possibly by controlling how self-motion and theta signals contribute to place cells coding.
-
- This data set includes behavioral tracking data corresponding to several
- navigational variables such as position, movement direction, speed and
- reward delivery. For sessions where behavior was combined with hippocampal
- recordings, it also includes spike times from hippocampal single units and
- LFP oscillations.
