Positron Emission Tomography (PET) with the tracer H215O was used to measure regional cerebral blood flow in 13 healthy volunteers during two experimental memory tasks, one of which was well-practiced and the other of which was novel. The materials used for the memory tasks consisted of two complex narratives (Story A and Story B from the Wechsler Memory Scale). Natural language materials were chosen because they similate experimentally the natural learning situation and permit study of the… 
Novel vs. Well-learned Memory for Faces: A Positron Emission Tomography Study
It is found that, unlike for verbal material, the retention interval and the familiarity level of the faces affected both the pattern and the size of activations in nonverbal memory.
Neural basis of novel and well‐learned recognition memory in schizophrenia: A positron emission tomography study
It is suggested that different neural pathways are engaged during novel recognition memory in patients with schizophrenia compared to healthy individuals and between‐ and within‐group differences.
Wechsler Memory Scale Revised Edition: Neural correlates of the visual paired associates subtest adapted for fMRI
The cerebellum showed significant activation in all conditions; its part in higher cognitive functions such as memory was thereby confirmed and the probability of thalamocortical connections during retrieval based on the Thalamus Connectivity Atlas was described.
Recalling word lists reveals "cognitive dysmetria" in schizophrenia: a positron emission tomography study.
Patients with schizophrenia fail to activate cortical-cerebellar-thalamic-cortical circuitry during recall of both well-learned and novel word lists.
A Common Language Network for Comprehension and Production: A Contribution to the Definition of Language Epicenters with PET
The present results provide conservative anatomofunctional definitions of the Broca, Wernicke, and basal language areas, which could be related to the interindividual variability of hemispheric language dominance.
Imaging Cognition II: An Empirical Review of 275 PET and fMRI Studies
Analysis of regional activations across cognitive domains suggested that several brain regions, including the cerebellum, are engaged by a variety of cognitive challenges.
Cortical networks for working memory and executive functions sustain the conscious resting state in man
The results suggest that brain activity during conscious REST is sustained by a large scale network of heteromodal associative parietal and frontal cortical areas, that can be further hierarchically organized in an episodic working memory parieto-frontal network, driven in part by emotions.
Visualizing how one brain understands another: a PET study of theory of mind.
A language-based TOM task activated distributed brain regions that are important for representing mental states of the self and others, retrieving memory of personal experiences, and coordinating and monitoring the overall performance of the task.
Neural enhancement and attenuation induced by repetitive recall
This study used event-related functional magnetic resonance imaging to investigate the effects of repetition on cued recall and found shifts in neural activity that occurred with repetition may reflect the dynamics of the retrieval process.
Effects of Level of Retrieval Success on Recall-Related Frontal and Medial Temporal Lobe Activations
It is argued that whereas the medial temporal lobe activation increased as the proportion of response words successfully recalled increased, the bilateral frontal lobeactivation increased in proportion to retrieval effort, which was greater when learning had been less good.
