LAA injection in the dentate gyrus reduced the expression of fear memory after contextual fear conditioning (a) Representative immunoblots for GFAP, NeuN and GAPDH in hippocampus for the control and LAA groups (n = 5). b Densitometric analysis of immunoblots for GFAP and NeuN (n = 5). c Immunofluorescence for GFAP, NeuN and DAPI in hippocampus for the control and LAA groups. d Schedule for contextual fear conditioning with control and LAA- injected mice. e During fear conditioning, the control and LAA groups displayed increased time freezing at 1st and 2nd electric shocks (1/2), the 2nd and 3rd (2/3) and after the 3rd electric shocks (3/E) (n = 10). f During fear expression, after 24 h the electric shock, the control and LAA groups showed increased time freezing (n = 10)
