NCBI ROFL: Shocking study finds it's hard to learn without a brain.

Unsuccessful reinforcement of a discrete action in paramecia, P. caudatum.

“Previous research into the possibility of learning in paramecium in this laboratory has shown that these organisms can learn to remain in a specific location based on cathode shock reinforcement. The present experiment was designed to assess whether paramecium could learn a discrete action as opposed to remaining in a specific area, using cathode shock as a reinforcer. Results for a sample of 40 indicate that such learning did not take place. It is possible that the learning of discrete actions requires a nervous system.”


Just for fun – an awesome movie of paramecium:
