“…Here the perirhinal cortex plays more of an associative role compared to its role in recognition memory (Kholodar-Smith et al, 2008b). Based on the anatomical projections described in Sections 3.2 and 3.3, it is not surprising that the perirhinal cortex is required for such associational learning as it forms a significant reciprocal connections with the amygdala Price, 1974, 1977;Ottersen, 1982;McDonald and Jackson, 1987;Pitkä nen et al, 2000;Pikkarainen and Pitkä nen, 2001;Furtak et al, 2007b), thalamus (Cornwall and Phillipson, 1988;Wouterlood et al, 1990;Shibata, 1993;McIntyre et al, 1996;Van Groen et al, 1999;Vertes et al, 2006), medial prefrontal cortex (Deacon et al, 1983;Sesack et al, 1989;Burwell and Amaral, 1998b;Delatour and Witter, 2002;Heidbreder and Groenewegen, 2003;Jones and Witter, 2007;Agster and Burwell, 2009) and hippocampus (Swanson and Cowan, 1977;Deacon et al, 1983;Kosel et al, 1983;Van Groen and Wyss, 1990;McIntyre et al, 1996;Naber et al, 1999;Shi and Cassell, 1999;Witter et al, 1999;Kloosterman et al, 2003b); regions of the brain which have been strongly linked with fear conditioning (Milad et al, 2006;Rosen and Donley, 2006).…”
