Unilateral hippocampal lesion does not impair ipsilateral RSC place cell activity. (A) (Top) Raw calcium time courses of 229 simultaneously imaged RSC neurons in the intact hemisphere of an example unilesion mouse. Neurons were sorted by the positions that elicited their maximum responses. (Bottom) Real (blue) and Bayesian decoded (red) position traces. (B) The same as A but for the lesioned hemisphere RSC of the same mouse. (C) Mean place cell fractions and position decoding errors in unilesion mice. Note that two mouse lines were used here (Thy1 and Ai93). Error bars are SEM over sessions. For unknown reasons, there were intrinsic differences between these lines in the observed place cell fractions.
