Planar cell polarity-mediated induction of neural stem cell expansion during axolotl spinal cord regeneration.

abstract：:An individual may need to take different actions to the same stimulus in different situations to achieve a given goal. The selection of the appropriate action hinges on the previously learned associations between stimuli, actions, and outcomes in the situations. Here, using a go/no-go paradigm and a symmetrical reward...
