  • T did not reliably increase until training in session ne6 ( 

  • * ). The preceding session (ne5→SAL) was followed by a unilateral hippocampal saline injection, for the first time instead of TTX. Thus, ne6 was the first session after which the bilaterally learned avoidance could be consolidated with both hippocampi functioning. T was also increased on ne7 (*) after only saline was injected following training in session ne6.
