SummaryThis paper reports evidence linking dorsolateral prefrontal cortex with one of the cognitive abilities that emerge between 7.5–12 months in the human infant. The task used was Piaget's Stage IV Object Permanence Test, known as AB (pronounced “A not B”). The AB task was administered (a) to human infants who were followed longitudinally and (b) to intact and operated adult rhesus monkeys with bilateral prefrontal and parietal lesions. Human infants displayed a clear developmental…

Working memory performance and neural activity in prefrontal cortex of peripubertal monkeys.
TLDR
The results show that in peripubertal monkeys the prefrontal cortex is capable of generating robust persistent activity in the delay periods of working memory tasks, although in general it may be more prone to stochastic failure than in adults.
Developmental progression of looking and reaching performance on the A-not-B task.
TLDR
Analysis of developmental progression of infants' performance on the looking and reaching versions of the A-not-B task suggests that performance differences between response modalities early in development can be attributed to major differences in the maturation of brain circuitry associated with the actual task response.
Development of working memory maintenance.
TLDR
It is indicated that brain processes supporting basic aspects of working memory across cortex are established by childhood, and evidence for continued immaturities in systems supporting working memory precision is found.
Freeze-Frame: a new infant inhibition task and its relation to frontal cortex tasks during infancy and early childhood.
TLDR
As expected, infants' ability to learn to selectively inhibit looks to the distractors at 9 months predicted performance at 24 months, however, performance differences in the two Freeze-Frame trial types early in the experiment also turned out to be an important predictor.
Frontal cortex functioning in the infant broader autism phenotype.
TLDR
Preliminary evidence for atypical frontal cortex functioning in the infant broader autism phenotype is provided through the study of infant siblings of children with an autism spectrum disorder (Sibs-ASD).
The neural mechanisms of object working memory: what is where in the infant brain?
TLDR
It is suggested that the development of a system involving the temporal cortex, thalamic and hippocampal structures and possibly the dorsolateral prefrontal cortex (later in development) can account for these behavioral results.
Off to a Good Start: The Early Development of the Neural Substrates Underlying Visual Working Memory
TLDR
Both the frontal-parietal control network and the posterior cortical storage areas are active from early infancy and this system undergoes focalization and some reorganization during early development, and the MTL plays a significant role in this process as well.
Is the Prefrontal Cortex Necessary for Establishing Cognitive Sets?
TLDR
The results suggest that the left rostral prefrontal cortex is indeed required for establishing a cognitive set but that the essential function is to support the functional connectivity among the task-related brain regions.
Infants' reaching in a multi-well A not B task
Abstract Forty-two infants aged 7.5–12.5 months were given two versions of a 7 well A not B task originally devised by Diamond, Neiderman, & Cruttenden (1994) . Diamond et al.’s task was confounded
Measures of frontal functioning and the emergence of inhibitory control processes at 10 months of age
TLDR
Electroencephalogram and electrocardiogram data provide insight into the development of integrated frontal functioning in infancy and show synchronized activity across distributed cortical regions appeared to be essential to inhibitory control processes during infancy.

Functional development of the prefrontal cortex in early life and the problem of neuronal plasticity.
TLDR
Two types of functional sparing after early brain damage are suggested: one, exemplified in the case of early dorsolateral lesions, in which the sparing becomes increasingly less impressive as the cortical area in question attains functional maturity; and the other, revealed in the monkeys with the early orbital ablations, inWhich a residual area may come to subsume the functions of the damaged cortex.
Operant behavioral analysis of memory loss in monkeys with prefrontal lesions
TLDR
The results support the idea that delayed-response deficits in monkeys with prefrontal lesions may be due in part to a defect in registering or encoding the correct spatial position in memory rather than to a loss in storage or retrieval processes.
Localization of function within the dorsolateral prefrontal cortex of the rhesus monkey.
TLDR
It is suggested that the cortex in the principal sulcus may be concerned with a form of spatial memory, whereas the arcuate cortex is concerned with some other, as yet unspecified function.
Functional development of the dorsolateral prefrontal cortex: An analysis utilizing reversible cryogenic depression
TLDR
The present study revealed that delayed-response and delayed-alternation performance are dissociable dorsolateral functions which achieve maturity at different rates, and provides strong validation for neurobehavioral analysis as a general approach to the study of regional maturation of the brain.

TLDR
It is suggested here that perseveration with immaturity or damage to the frontal lobe is better characterized as lack of inhibitory control, and tasks that are most likely to require frontal cortex function are those that demand both short-term memory and inhibitory Control.
The role of frontal and parietal cortex in cognitive processing: tests of spatial and sequence functions.
TLDR
The data support the view that a distinction between personal and extrapersonal spatial orientation is relevant to posterior parietal function but indicate that neither sequencing per se nor personal spatial orientation or spatial memory per se is dependent on intact frontal functioning.
Posterior parietal association cortex of the monkey: command functions for operations within extrapersonal space.
TLDR
A large proportion of area 5 neurons were relatively insensitive to passive joint rotations, as compared with similar neurons of the postcentral gyrus, but were driven to high rates of discharge when the same joint was rotated during an active movement of the animal.
Extrapersonal spatial orientation: The role of posterior parietal, anterior frontal, and inferotemporal cortex
TLDR
The present study indicates that the posterior parietal cortex is essentially involved in coding spatial relations between external objects, and the anterior frontal cortex mediates a function superordinate to a spatial factor.

TLDR
The FC-induced decrements in proportion of correct responses suggest a faster loss from short-term memory of both spatial and nonspatial information.
Delay-related activity of prefrontal neurons in rhesus monkeys performing delayed response
TLDR
Cellular evidence is provided that prefrontal neurons are responsive to temporal as well as spatial features of the delayed-response task and the involvement of a subset of these is particularly critical in the first few seconds of the delay.
