In 1962 Milner showed that STM was impaired in patients with hippocampal
lesions.
Lesions of Hip cause:
- loss of passive evasive behavior though do not affect active evasive
behavior (in some experiments it becomes even better); 
- also, re-education is almost impossible;
- animals could not locate objects in space correctly;
- long-term conditioning is entirely impossible.
Thus Hip is really vital to the STM ---> LTM conversion.
