Interaction between the amygdala and the medial temporal lobe memory system predicts better memory for emotional events. (2004, background): “This finding suggests that these regions interact (Amaral et al., 1992; Pitkanen et al., 2000) and with animal more intimately during the encoding of emotional stimuli evidence specifically identifying amygdalar modulation than during the encoding of neutral stimuli.”
Awake reactivation of emotional memory traces through hippocampal-neocortical interactions (2016, positive): “An interpretation of this finding in terms of increased connectivity is, however, in line with anatomical studies in rodents, which have indicated there are reciprocal connections between the amygdala and the hippocampus (Pitkänen et al., 2000), making it possible for these regions to functionally i”
Regional dissociations within the hippocampus--memory and anxiety. (2004, background): “It is closely connected to the bed nucleus of the stria terminalis (BNST) and the amygdala [57,72,102,105,123,129], as well as other subcortical structures which are associated with the hypothalamic-pituitary–adrenal (HPA) axis [3,62,118,123, 133].”
Allostasis: a model of predictive regulation. (2012, positive): “The central nucleus connects reciprocally with the hippocampus, to which it is adjacent, thus allowing efficient storage and retrieval of anxious memories [25].”
Anatomical gradients of adult neurogenesis and activity: young neurons in the ventral dentate gyrus are activated by water maze training (2009, neutral): “…and amygdala, structures involved in responding to anxiogenic, fearful and stressful stimuli (Swanson and Cowan, 1977; Risold and Swanson, 1996; Pitkanen et al., 2000; Petrovich et al., 2001), whereas the dorsal hippocampus receives input from the dorsolateral portion of the entorhinal cortex…”
Cognitive modulation of pain: how do attention and emotion influence pain processing? (2002, background): “…showing activation of entorhinal cortex during the modulation of pain by anxiety (Ploghaus et al., 2001) at least indirectly implicates this circuitry in anxietyrelated pain modulation, since there are strong reciprocal connections between amygdala and entorhinal cortex (Pitkanen et al., 2000).”
Plastic Synaptic Networks of the Amygdala for the Acquisition, Expression, and Extinction of Conditioned Fear (2010, neutral): “D: synchronized theta activity in LA and CA1 during retrieval of conditioned fear.”
Alcohol: Effects on Neurobehavioral Functions and the Brain (2007, background): “…of motivational significance of stimuli and to the mediation and control of major emotions such as love, fear, rage, anxiety, and general negative affective states (Aggleton 2000; Amaral et al. 2003; Breiter and Rosen 1999; Everitt et al. 2003; LeDoux 2003; Pitkänen et al. 2000; Rolls 2000).”
Multiple parallel memory systems in the brain of the rat. (2002, background): “The lateral and basolateral nuclei also project directly to the ventral hippocampus and subiculum, and to entorhinal cortex which, in turn, also projects to the hippocampus (Pikkarainen, Ronkko, Savander, Insausti, & Pitkanen, 1999; Pitkanen et al., 2000).”
