This review reports on what has been learned about the network mechanisms that underlie abnormal delta oscillations.
This multicenter collaborative study explores whether biologically defined groups of genes are enriched in episodic memory performance across age, memory encoding–related brain activity, and Alzheimer disease.
This Neuroscience and Psychiatry article discusses the implications of relational memory deficits in schizophrenia and whether they are a reliable cognitive marker for the disease.
This positron emission tomographic functional magnetic resonance imaging study found in vivo evidence for a deficit in the capacity for dopamine release in the dorsolateral prefrontal cortex in schizophrenia.
This multicenter, prospective cohort study provides support for the deleterious effect of elevated amyloid-β levels on cognitive function in preclinical Alzheimer disease.
Rasetti and colleagues investigated whether altered brain responses, particularly in the hippocampus and parahippocampus, during the encoding phase of a simple declarative memory task were also observed in the unaffected siblings of patients with schizophrenia.
To examine the neural correlates of recall of life events judged to be of causal significance in conversion disorder (CD), Aybek et al performed an fMRI study of 12 patients with motor CD and 13 healthy control subjects. Stressful life events were assessed using the Life Events and Difficulties Schedule and rated for their likelihood to cause CD.
Young et al determine whether individuals at high familial risk for developing major depressive
disorder (MDD) show an autobiographic memory (AM) overgenerality bias. The authors use functional
magnetic resonance imaging to assess differences in functional correlates of AM recall across
high-risk, currently depressed MDD, and healthy control samples.
