The unity and diversity of executive functions and their contributions to complex “Frontal Lobe” tasks: a latent variable analysis
- COGNIT PSYCHOL
, 2000
"... This individual differences study examined the separability of three often postulated executive functions—mental set shifting ("Shifting"), information updating and monitoring ("Updating"), and inhibition of prepotent responses ("Inhibition")—and their roles in complex ..."

"frontal lobe" or "executive" tasks. One hundred thirty-seven college students performed a set of relatively simple experimental tasks that are considered to predominantly tap each target executive function as well as a set of frequently used executive tasks: the Wisconsin Card
Storage and executive processes in the frontal lobes.
- Science,
, 1999
"... The human frontal cortex helps mediate working memory, a system that is used for temporary storage and manipulation of information and that is involved in many higher cognitive functions. Working memory includes two components: short-term storage (on the order of seconds) and executive processes th ..."

and control tasks thus reveals activations due to the process of interest (6). These paradigms contrast with standard neuropsychological tasks that may have diagnostic value for patients with frontal cortical lesions but that do not reveal individual cognitive processes. Storage Processes and the Frontal
Frontal lobe contributions to theory of mind
- Journal of Cognitive Neuroscience
, 1998
"... n “Theory of mind, ” the ability to make inferences about others ’ mental states, seems to be a modular cognitive capacity that underlies humans ’ ability to engage in complex social interaction. It develops in several distinct stages, which can be measured with social reasoning tests of increasing ..."

dorsolateral prefrontal cortex (n = 5) on a series of theory of mind tasks varying in dif�culty. Bilateral orbito-frontal lesion patients performed similarly to individuals with Asperger’s syndrome, performing well on simpler tests and showing de�cits on tasks requiring more subtle social reasoning
Monitoring and control of action by the frontal lobes
- Neuron
, 2002
"... Success requires deciding among alternatives, controlling the initiation of movements, and judging the consequences of actions. When alternatives are difficult to distinguish, habitual responses must be over-come, or consequences are uncertain, deliberation is necessary and a supervisory system exer ..."

exerts control over the processes that produce sensory-guided movements. We have investigated these processes by recording neural activity in the frontal lobe of macaque monkeys performing a countermanding task. Distinct neurons in the frontal eye field respond to visual stimuli or control the production
Cortical networks for visual reaching: physiological and anatomical organization of frontal and parietal lobe arm regions
- Cereb. Cortex
, 1996
"... The functional and structural properties of the dorsolateral frontal lobe and posterior parietal proximal arm representations were studied in macaque monkeys. Physiological mapping of primary motor (Ml), dorsal premotor (PMd), and posterior parietal (area 5) cortices was performed in behaving monkey ..."

nonuniformly within the task-related areas in both frontal and parietal cortices. Within the frontal lobe, moving caudally from PMd to the Ml, the activity that signals for the visuospatial events leading to target localization decreased, while the activity more directly linked to movement generation increased
Staying on the job: the frontal lobes control individual performance variability
- Brain
, 2003
"... The causes of variability of performance by individual subjects have rarely been investigated, although exces-sive variability or inconsistency may be a functionally signi®cant factor for many real-life activities. Our objective was to determine whether patients with focal frontal brain lesions have ..."

lobe MRI morphology and frontal cerebral blood flow
"... The catechol-O-methyl transferase (COMT) gene is considered a leading schizophrenia candidate gene. Although its role in increasing schizophrenia susceptibility has been conflicting, recent studies suggest the valine allele may contribute to poor cognitive function in schizophrenia. V158M COMT genot ..."

analyses using [15O]H2O positron emission tomography (PET) cerebral blood flow data found Val/Val patients had higher frontal lobe activation than Met/Met patients while performing the one-back task. Overall, these findings do not support a major role for COMT in increasing susceptibility for schizophrenia
Different underlying impairments in decisionmaking following ventromedial and dorsolateral frontal lobe damage in humans
- Cerebral Cortex
, 2005
"... Ventromedial prefrontal cortex (VMF) damage can lead to impaired decision-making. This has been studied most intensively with the Iowa gambling task (IGT), a card game that asks subjects to overcome an initial attraction to high-payoff decks as losses begin to accrue. VMF subjects choose from the hi ..."

There is also conflicting evidence regarding the role of the dorsolateral prefrontal cortex (DLF) in this task. The present study examined whether poor
THEORY OF MIND AND THE FRONTAL LOBES

Its cerebral organization is not enough established, even though the literature suggests the relevant role of the frontal lobes. Objective: To evaluate frontal lobe patients and controls in To ..."

Twenty Questions Task and Frontal Lobe Dysfunction
