The effects of external cue overlap and internal goals on selective memory retrieval as revealed by electroencephalographic (EEG) neural pattern reinstatement

This study uses EEG to show how external cues and internal goals influence memory retrieval by analyzing neural pattern reinstatement during recall tasks.

Neural Evidence of Functional Compensation for Fluid Intelligence in Healthy Ageing

The paper examines brain activity and cognitive performance in older adults during a problem-solving task, finding increased cuneal cortex activity with age and performance, suggesting functional compensation for fluid intelligence.

Does Hemispheric Asymmetry Reduction in Older Adults (HAROLD) in motor cortex reflect compensation?

The paper investigates whether age-related hemispheric asymmetry reduction in motor cortex reflects compensation, finding no evidence for a compensatory mechanism.

Perceptual and Semantic Representations at Encoding Contribute to True and False Recognition of Objects

The paper uses fMRI and representational similarity analysis to show that both perceptual and semantic representations contribute to true and false recognition of objects, with fine-grained features aiding accurate recall and coarse categories linked to forgetting.

Cue overlap supports pre-retrieval selection in episodic memory: ERP evidence

The paper uses ERP data to show that pre-retrieval selection in memory is supported by cue overlap between retrieval cues and targeted memory traces, despite better memory for pictures.

Increased prefrontal activity with aging reflects nonspecific neural responses rather than compensation

The paper uses multivariate analysis to show increased prefrontal activity in older adults reflects reduced efficiency rather than compensation for cognitive decline.

Age-related changes in the neural networks supporting semantic cognition: A meta-analysis of 47 functional neuroimaging studies

This study uses a meta-analysis of 47 functional neuroimaging studies to examine age-related changes in neural networks supporting semantic cognition, finding a shift from semantic-specific to domain-general resources in older adults.
