Positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) have been extensively used to explore the functional neuroanatomy of cognitive functions. Here we review 275 PET and fMRI studies of attention (sustained, selective, Stroop, orientation, divided), perception (object, face, space/motion, smell), imagery (object, space/ motion), language (written/spoken word recognition, spoken/ no spoken response), working memory (verbal/numeric, object, spatial, problem solving… 
Verbal and spatial working memory in older individuals: A positron emission tomography study
TLDR
The design addresses the question of regions related to manipulation and representation, most particularly comparing spatial and verbal working memory, and largely confirmed conclusions from the review on the organization of working memory into dorsal prefrontal manipulation and ventrolateral prefrontal maintenance areas and representation in dorsal and ventral paths.
Dissociation of verbal working memory system components using a delayed serial recall task.
TLDR
fMRI was used to investigate the neural substrates of component processes in verbal working memory and found that left inferior frontal and supplementary motor regions showed patterns of stimulus and temporal sensitivity implicating them in distinct aspects of articulatory rehearsal, while no regions showed a pattern of sensitivity consistent with a role in phonological storage.
Neuroimaging studies of working memory:
TLDR
A potential fourth executive function is considered: selective attention to features of a stimulus to be stored in WM which leads to increased probability of activating the medial prefrontal cortex (BA 32) in storage tasks.
Dissociation of neural correlates of verbal and non-verbal visual working memory with different delays
TLDR
Right DLPFC seems to be engaged in non-verbal WM tasks especially for long delays, and the results indicate that even slightly different memory maintenance intervals engage largely differing networks and that this novel finding may explain differing results in previous verbal/non- verbal WM studies.
Functional imaging of memory processes in humans: positron emission tomography and functional magnetic resonance imaging.
TLDR
A PET-study on episodic memory in human volunteers will be used to illustrate design, analysis, and interpretation of functional imaging studies on memory to reduce the complexity of the data and to extract the processes of interest.
Functional MRI Studies on Human Declarative Memory
Declarative memory is defined as the conscious memory for facts and events. The medial temporal lobe (MTL) structures, i.e., the hippocampus with the adjacent parahippocampal region, are considered
An Event-Related fMRI Study of Phonological Verbal Working Memory in Schizophrenia
TLDR
These findings suggest that a wider network of frontal and parietal regions support WM maintenance in correct trials compared with error trials in both groups and underscore the value of parsing the sources of memory errors in fMRI studies because of the non-linear nature of the brain-behavior relationship.
Special issue on functional neuroimaging of memory
The introduction of functional neuroimaging techniques, such as positron emission tomography (PET) and functional MRI (fMRI), has had a tremendous impact in the development of cognitive neuroscience
Discrimination of temporal information at the cerebellum: functional magnetic resonance imaging of nonverbal auditory memory
TLDR
It is suggested that the storage of precise temporal structures relies on a cerebellar-prefrontal loop that allows for temporal organization of verbal sequences and phoneme encoding based on durational operations in a linguistic context.
Encoding-related brain activity during deep processing of verbal materials: a PET study
TLDR
This work has demonstrated that several regions, including the medial temporal lobe, play a role in episodic memory encoding, and used positron emission tomography to differentiate these two kinds of regions.

Imaging Cognition: An Empirical Review of PET Studies with Normal Subjects
TLDR
PET studies of higher-order cognitive processes, including attention (sustained and selective), perception (of objects, faces, and locations), language (word listening, reading, and production), working memory (phonological and visuo-spatial), semantic memory retrieval, episodic memory retrieval (verbal and nonverbal), priming, and procedural memory are reviewed.
Mapping cognition to the brain through neural interactions.
TLDR
The results suggest that activity in portions of the RPFC can reflect either memory retrieval mode or retrieval success depending on other brain regions to which it is functionally linked, and imply that regional activity must be evaluated within the neural context in which it occurs.
The neural correlates of intentional learning of verbal materials: a PET study in humans.
TLDR
The data are interpreted to suggest that when subjects use cognitive strategies of semantic processing and rote-rehearsal to learn words, they invoke discrete regions of the left prefrontal cortex which leads to a neurophysiological memory trace which can be used to guide subsequent memory retrieval.
A positron emission tomography study of the short-term maintenance of verbal information
TLDR
Based on converging results in this and previous studies, dorsolateral prefrontal cortical areas appear to contribute to the maintenance of both verbal and nonverbal information, whereas left frontal opercular regions appear to be involved specifically in the rehearsal of verbal material.
Dissociating verbal and spatial working memory using PET.
TLDR
Results of three experiments used position emission tomography to study the neural basis of human working memory indicate that verbal and spatial working memory are implemented by different neural structures.
Functional Anatomic Studies of Memory Retrieval for Auditory Words and Visual Pictures
TLDR
Findings suggest a pathway that is commonly used during the episodic retrieval of picture and word stimuli under these conditions, and many areas in this pathway overlap with areas previously activated by a different set of retrieval tasks using stem-cued recall, demonstrating their generality.
Brain systems for encoding and retrieval of auditory-verbal memory. An in vivo study in humans.
TLDR
The results of this study indicate that separate brain systems are engaged during the encoding and retrieval phases of episodic auditory-verbal memory, and engage a different, but overlapping, system to that engaged by retrieval from semantic memory.

TLDR
Three highly reliable findings linking memory-related cognitive processes to brain activity are discussed, illustrating how neuroimaging techniques can be used to study memory processes and can both complement and extend data derived through other means.
Spatial versus Object Working Memory: PET Investigations
TLDR
The results of the three experiments clearly imply that different working-memory buffers are used for storing spatial and object information.
Activation of the prefrontal cortex during judgments of recency: a functional MRI study.
TLDR
This study provides further evidence that memory for temporal context requires the prefrontal cortex and is the first to demonstrate this association in healthy humans and suggests the possibility that recognition of context and recognition of episodic content may involve similar brain systems.
