Beta-adrenergic antagonism alters functional connectivity during associative processing in a preliminary study of individuals with and without autism

Beta-adrenergic antagonism (e.g., propranolol) has been associated with cognitive/behavioral benefits following stress-induced impairments and for some cognitive/behavioral domains in individuals with autism spectrum disorder (ASD). In this …

Beta-adrenergic antagonism modulates functional connectivity in the default mode network of individuals with and without autism spectrum disorder

The beta-adrenergic antagonist propranolol benefits some social and communication domains affected in autism spectrum disorder (ASD), and these benefits appear to be associated with increased functional connectivity (FC) in the brain during task …

The effects of age on the neural correlates of recollection success, recollection-related cortical reinstatement, and post-retrieval monitoring

Functional magnetic resonance imaging (fMRI) was used to investigate whether age-related differences in episodic memory performance are accompanied by a reduction in the specificity of recollected information. We addressed this question by comparing …

Pattern reactivation co-varies with activity in the core recollection network during source memory

Neuroimaging studies of episodic memory have consistently demonstrated that memory retrieval involves reactivating patterns of neural activity that were present during encoding, and these effects are thought to reflect the qualitative retrieval …

Neural reinstatement and the amount of information recollected

Recent functional neuroimaging studies have attempted to understand the cognitive and neural bases of episodic memory retrieval, as well as the extent to which different retrieval judgments reflect qualitative as opposed to continuous changes in …

Recollection, familiarity, and content-sensitivity in lateral parietal cortex: A high-resolution fMRI study

Numerous studies have identified brain regions where activity is consistently correlated with the retrieval (recollection) of qualitative episodic information. This ‘core recollection network’ can be contrasted with regions where activity differs …

Dissociation of Recollection-Related Neural Activity in Ventral Lateral Parietal Cortex

fMRI responses to recognition memory test items in two regions of ventral lateral parietal cortex-the angular gyrus and temporo-parietal junction (TPJ)-are enhanced when recognition is accompanied by recollection. According to the 'episodic buffer' …

Encoding-retrieval overlap in human episodic memory: a functional neuroimaging perspective

The principle of transfer-appropriate processing and the cortical reinstatement hypothesis are two influential theoretical frameworks, articulated at the psychological and neurobiological levels of explanation, respectively, that each propose that …

Multiple repetitions reveal functionally and anatomically distinct patterns of hippocampal activity during continuous recognition memory

We used a continuous recognition procedure that included multiple presentations of test items, along with high-resolution functional magnetic resonance imaging (fMRI), to investigate the relationship between item novelty and recognition-related …

Recollection and the reinstatement of encoding-related cortical activity

The neural correlates of episodic memory retrieval (``recollection'') differ according to the type of information contained in the recollected episode. Such content-specific recollection effects have been hypothesized to reflect the reinstatement of …
