In three rats, microdrives were targeted simultaneously to LEC and the proximal part of CA1. A multi-tetrode parallel recording system (Neuralynx or Axona) was used to obtain local field ...

In the first rat, the stereotaxic coordinates (in mm) were −5.0 anteroposterior and 5.0 mediolateral; seven tetrodes hit CA1, one tetrode hit CA2 and three tetrodes hit CA3 (one tetrode did not ...
