The functional anatomy of planning was investigated using the Tower of London task. Activation was observed in a distributed network of cortical areas incorporating prefrontal, cingulate, premotor, parietal and occipital cortices. Activation in corresponding areas has been observed in visuospatial working memory tasks with the exception of the rostral prefrontal cortex. This area may be identified with the executive components of planning comprising response selection and evaluation. Enhanced… Expand

Frontostriatal system in planning complexity: a parametric functional magnetic resonance version of tower of london task
TLDR
Investigation of which brain structures are recruited in planning tasks of increasing complexity found increasing task complexity was correlated with activity in the left anterior prefrontal cortex, a region supposed to be specifically involved in third-order higher cognitive functioning. Expand
The special involvement of the rostrolateral prefrontal cortex in planning abilities: An event-related fMRI study with the Tower of London paradigm
TLDR
Current findings suggest that planning involves an extensive fronto-parieto-thalamic network and the rostrolateral prefrontal cortex seems to be the only region that is exclusively reactive to planning specific processes. Expand
Individual differences in prefrontal cortical activation on the Tower of London planning task: implication for effortful processing
TLDR
It is shown that healthy subjects with different levels of performance in the Tower of London planning task exhibit different patterns of brain activation, and Superior performers showed a significantly more spatially extended activation in the left dorsolateral prefrontal cortex than did standard performers. Expand
Frontal and parietal participation in problem solving in the Tower of London: fMRI and computational modeling of planning and high-level perception
TLDR
This study triangulates executive planning and visuo-spatial reasoning in the context of the Tower of London (TOL) task by using a variety of methodological approaches, which converge on a deepening understanding of the combination of perceptual and conceptual processes in this type of visual problem solving. Expand
Dynamic functional changes associated with cognitive skill learning of an adapted version of the Tower of London task
TLDR
Improved performance on the TOL task was associated with a significant decrease of activity in the medial orbitofrontal and frontopolar cortices over the course of learning, areas thought to be involved in decision making, guessing, and monitoring of feedback information. Expand

TLDR
Patients with frontal damage are shown to have deficits in their use of strategies to improve performance in a spatial working memory task and capacity to make an extra-dimensional shift due to a high-order failure of inhibition in an attentional set-shifting paradigm. Expand
Neural mechanisms of planning: A computational analysis using event-related fMRI
TLDR
A novel adaptation of the Tower of Hanoi task and event-related functional MRI revealed brain areas in which the time course of activity varied as a function of goal-processing events, and two distinct time courses of activation were identified. Expand
Application of a neuropsychological activation probe with SPECT: the ‘Tower of London’ task in healthy volunteers
TLDR
The present study reports on the TOL task under classical neuropsychological test conditions using single photon emission computed tomography (SPECT) activation in 10 healthy subjects, validating the use of the T OL task in a SPECT activation paradigm. Expand
A fronto-parietal network for rapid visual information processing: a PET study of sustained attention and working memory
TLDR
The functional anatomy of the RVIP task is investigated using positron emission tomography derived measures of regional cerebral blood flow (rCBF) in eight healthy volunteers and it is suggested that these data are consistent with the existence of a right fronto-parietal network for sustained, and possibly selective, attention, and a left frontospecific network for the phonological loop component of working memory. Expand
The role of the anterior prefrontal cortex in human cognition
TLDR
The results indicate that the fronto-polar prefrontal cortex selectively mediates the human ability to hold in mind goals while exploring and processing secondary goals, a process generally required in planning and reasoning. Expand

Neural correlates of planning ability: Frontal lobe activation during the tower of London test
TLDR
The level of rCBF was significantly increased in the left pre-frontal cortex during the Tower of London task, and subjects who took more time planning their moves, and less moves to complete a problem had a significantly higher level. Expand
Coactivation of prefrontal cortex and inferior parietal cortex in working memory tasks revealed by 2DG functional mapping in the rhesus monkey
TLDR
These are the first results showing concurrent metabolic activation of the prefrontal and parietal cortex in monkeys performing working memory tasks and they support the suggestion that these cortical regions represent two important nodes in a neural network mediating spatial working memory in the monkey. Expand
Functional mapping of brain areas implicated in auditory--verbal memory function.
TLDR
Brain regions showing increases in rCBF in these comparisons included the thalamus, left anterior cingulate, right parahippocampal gyrus, cerebellum and the superior temporal gyrus. Expand
Spatial working memory in humans as revealed by PET
TLDR
P positron emission tomography studies of regional cerebral blood flow in normal humans that reveal activation in right-hemisphere prefrontal, occipital, parietal and premotor cortices accompanying spatial working memory processes begin to uncover the circuitry of a working memory system in humans. Expand
Practice-related changes in human brain functional anatomy during nonmotor learning.
TLDR
Examination of the functional anatomy of the human brain with positron emission tomography during the naive and practiced performance of a simple verbal response selection task indicates that two distinct circuits can be used forverbal response selection and normal subjects can change the brain circuits used during task performance following less than 15 min of practice. Expand
Brain regions associated with acquisition and retrieval of verbal episodic memory
TLDR
The results provide clear evidence that episodic memory involves a network of specific prefrontal and posterior structures which can be fractionated into different component processes. Expand

An information-processing model is outlined that predicts that performance on non-routine tasks can be impaired independently of performance on routine tasks. The model is related to views on frontalExpand
Role of the human anterior cingulate cortex in the control of oculomotor, manual, and speech responses: a positron emission tomography study.
TLDR
The localization of output-specific rCBF changes within the human ACC is consistent with the known somatotopic organization of the cingulate cortex in the monkey, and it is tentatively proposed that the ACC participates in motor control by facilitating the execution of the appropriate responses and/or suppressing the Execution of the inappropriate ones.

Dissociation of human mid-dorsolateral from posterior dorsolateral frontal cortex in memory processing.
TLDR
These findings provide direct evidence that, just as the monkey brain, the human lateral frontal cortex is functionally heterogeneous and that comparable anatomical areas underlie similar functions in the two species. Expand
Willed action and the prefrontal cortex in man: a study with PET
TLDR
Willed acts in the two response modalities studied (speaking a word, or lifting a finger) were associated with increased blood flow in the dorsolateral prefrontal cortex (Brodmann area 46) and decreases in blood flow were also associated, but the location of these decreases was modality dependent.
