The unity and diversity of executive functions and their contributions to complex “Frontal Lobe” tasks: a latent variable analysis

by Akira Miyake, Naomi P. Friedman, Michael J. Emerson, Alexander H. Witzki, Amy Howerter, Tor D. Wager - 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.

by Edward E Smith , John Jonides - 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 ..."

Example-based learning for view-based human face detection

by Kah-kay Sung, Tomaso Poggio - IEEE Transactions on Pattern Analysis and Machine Intelligence , 1998
"... Abstract—We present an example-based learning approach for locating vertical frontal views of human faces in complex scenes. The technique models the distribution of human face patterns by means of a few view-based “face ” and “nonface ” model clusters. At each image location, a difference feature v ..."

Frontal lobe contributions to theory of mind

by Valerie E. Stone, Simon Baron-cohen, Robert T. Knight - 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 ..."

The medial temporal lobe memory system

by Larry R. Squire, Stuart Zola-morgan - Science , 1991
"... Studies ofhuman amnesia and studies of an animal model of human amnesia in the monkey have identified the anatomical components of the brain system for memory in the medial temporal lobe and have illuminated its function. This neural system consists of the hippocampus and adjacent, anatomically rela ..."

lobe is a large region that includes the hippocampal formation (6), the amygdaloid complex, and adjacent cortical areas (Fig. 1). It has therefore been difficult to determine from human cases precisely which structures and connections within the medial temporal lobe are important for memory.

Monitoring and control of action by the frontal lobes

by Jeffrey D. Schall, Veit Stuphorn, Cognitive Neuroscience - 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

lobe MRI morphology and frontal cerebral blood flow

by unknown authors
"... 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 ..."

The problem of the frontal lobe: a reinterpretation

by Walle J. H. Nauta - Journal of Psychiatric Research , 1971
"... THE FRONTAL lobe, despite decades of intensive research by physiologists, anatomists and clinicians, has remained the most mystifying of the major subdivisions of the cerebral cortex. Unlike any other of the great cerebral promontories, the frontal lobe appears not to contain a single sub-field that ..."

Staying on the job: the frontal lobes control individual performance variability

by Donald T. Stuss, Kelly J. Murphy, Malcolm A. Binns, Michael P. Alex - 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 ..."

Disturbances in consistency of per-formance were observed primarily in patients with frontal lesions. Damage to the frontal lobes impairs

Cortical networks for visual reaching: physiological and anatomical organization of frontal and parietal lobe arm regions

by Paul B. Johnson, Stefano Ferraina, Luigi Bianchi, Roberto Caminiti - 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 ..."
