Basic Memory Mechanisms
Functional neuroimaging studies have associated episodic memory with activations in medial temporal lobe (MTL), prefrontal cortex (PFC), posterior parietal cortex (PPC), and other brain regions (Cabeza et al., 2008; Cabeza & Nyberg, 2000; Dew & Cabeza, 2011). We investigae the contributions of these regions and their subregions to different memory encoding and retrieval processes. For more information, click on the projects listed on the right.

Emotion can enhance or impair memory processes (Dolcos et al., 2006; LaBar & Cabeza, 2006). The modulatory effect of emotion on memory may reflect direct effects of the amygdala (i.e., an emotion region) on the MTL memory system (i.e., a memory region) or indirect effects mediated by attentional, working memory, and semantic processes mediated by PFC and parietal regions. We investigate these effects both during encoding and during retrieval. For more information, click on the projects listed on the right.

The goal of the new discipline of cognitive neuroscience of aging (Cabeza, Nyberg, & Park, 2004) is to reveal the neural mechanisms of age-related changes in cognition (Dennis & Cabeza, 2008). At a broader level, we investigate age-related compensatory mechanisms shared across cognitive domains (Cabeza & Dennis, in press), and white matter changes, measured with DTI (Davis et al., 2008), that have a general impact on cognition . At the domain level, we investigate age effects on the neural mechanisms of memory (Daselaar & Cabeza, in press) and emotion (St. Jacques et al., in press).
