Shared and distinct contributions of rostrolateral prefrontal cortex to analogical reasoning and episodic memory retrieval

Andrew Westphal, Nicco Reggente, Kaori Ito, Jesse Rissman Abstract: Rostrolateral prefrontal cortex (RLPFC) is widely appreciated to support higher cognitive functions, including analogical reasoning and episodic memory retrieval. However, these tasks have typically been studied in isolation, and thus it is unclear whether they involve common or distinct RLPFC mechanisms. Here, we introduce a novel […]

Decoding fMRI Signatures of Real-world Autobiographical Memory Retrieval

Jesse Rissman, Tiffany E. Chow, Nicco Reggente, and Anthony D. Wagner Abstract: Extant neuroimaging data implicate frontoparietal and medial-temporal lobe regions in episodic retrieval, and the specific pattern of activity within and across these regions is diagnostic of an individual’s subjective mnemonic experience. For example, in laboratory-based paradigms, memories for recently encoded faces can be […]

Decoding cognitive task-sets from rostral prefrontal cortex functional connectivity patterns

Westphal, A.J., Reggente, N., Ito, K., Fortuna, W., & Rissman, J. HBM_2013_Poster  HBM 2013 Abstract Resting state fMRI connectivity analyses have identified a number of distinct functional brain networks, including the fronto-parietal task control network (FPTCN), the dorsal attention network (DAN), and the default mode network (DMN) (e.g., Vincent et al., 2008, Power et al., […]

MVPA (Multi Variate/Voxel Pattern Analysis): The Basics

Often times I feel restrained by the unfortunate, inherent shortcomings of medical and functional imaging data. The entire process is subject to a vast array of variability, assumptions, and “warpings” in many senses of the word. These, however minute the calculations and interpolations may be, carry an overarching sentiment of being haphazard. However, differences between […]
