Aron Keith Barbey (born January 6, 1977) is an American cognitive neuroscientist, who investigates the neural architecture of human intelligence and brain plasticity. [1] [2] Barbey is the Emanuel Donchin Professorial Scholar of Psychology and a Professor of Psychology, Neuroscience, and Bioengineering at the University of Illinois. [3] [4] [5] He is director of the Decision Neuroscience Laboratory at the Beckman Institute for Advanced Science and Technology, [6] [2] and founding director of the Center for Brain Plasticity at the Beckman Institute, where he leads the Intelligence, Learning, and Plasticity (ILP) Initiative. [3]
He has used both classical lesion methods and functional magnetic resonance imaging (fMRI) techniques to better understand neural architecture and its relationship to intelligence. [3] Barbey used lesion mapping to study Vietnam veterans who had suffered brain trauma. He was able to record diagnostic images of their brains and relate this anatomical data to their documented problems, creating a "brain atlas" linking cognitive functions to neural organization. [6] [7] He has suggested a framework called “structured event complex theory” that describes the inferential architecture of the prefrontal cortex. [8]
His research group examines the effects of physical fitness, [9] nutrition [10] [11] [12] [13] and cognitive neuroscience interventions (including TDCS) [6] on brain health and intelligence across the human lifespan. In 2019, Barbey was awarded the Mensa Foundation Prize for his neuroscientific work studying human intelligence. [3] [14] [15]
Aron Barbey received a B.A. from the University of Texas at Dallas in 1999, and a Ph.D. in Psychology from Emory University, Atlanta, Georgia, in 2007. [16]
From 2007-2011 Barbey was a Postdoctoral Fellow in the Cognitive Neuroscience Section of the National Institute of Neurological Disorders and Stroke at the National Institutes of Health, Bethesda, Maryland. [16] [1] There he studied Vietnam veterans affected by brain trauma. They experienced differential deficits depending on the locations and size of their injuries. [6] Barbey also served as an adjunct professor of psychology at Georgetown University, Washington, D.C., beginning in 2008. [16]
In 2011 Barbey was appointed to the College of Applied Health Sciences at the University of Illinois, and became an Institute Affiliate of the Beckman Institute for Advanced Science and Technology. [16] By 2012, he was the director of the Decision Neuroscience Laboratory at the Beckman Institute. [2] In 2018, the Center for Brain Plasticity at the Beckman Institute was formed, under the leadership of co-directors Aron Barbey and Neal J. Cohen, leaders of the center's Intelligence, Learning, and Plasticity (ILP) Initiative. [17]
Aron Barbey is Associate Editor of Frontiers in Human Neuroscience . [18] Barbey is also on the Editorial Boards of NeuroImage , [19] Intelligence , [20] and Thinking & Reasoning. [21] He is a co-editor of the Cambridge Handbook of Intelligence and Cognitive Neuroscience (2021). [22]

Barbey's research investigates the effects of human brain damage on intellectual and social functions, with particular emphasis on the prefrontal cortex. [6] [1]
Studies of patients with frontal lobe damage have a long history in the neuroscience of intelligence and provide a direct way to test whether regions in the prefrontal cortex are necessary for specific intellectual abilities. However, it was only recently that the limited applicability and specificity of small sample studies of focal brain damage were overcome by contemporary lesion mapping approaches. [23] [24]
In a series of studies, [1] Barbey's research group investigated almost 200 patients with focal brain injuries and mapped the architecture of executive, social, and emotional brain systems. His research has helped to identify and characterize the neural systems underlying general intelligence, [25] [6] [10] [26] emotional intelligence, [6] [27] [28] social intelligence, [29] fluid intelligence, [30] [31] working memory, [32] cognitive flexibility, [33] and discourse comprehension. [34]
Barbey's research has also revealed molecular genetic markers that predict general intelligence following traumatic brain injury. [35] [36]
A central goal of Barbey's research is to establish and validate cognitive neuroscience-directed interventions to enhance human intelligence. Barbey is the Principal Investigator of the IARPA-sponsored INSIGHT project, along with co-investigators Arthur F. Kramer, Neal J. Cohen, and Charles H. Hillman. [37] [38] [6]
Barbey has proposed a network neuroscience theory of human intelligence that emphasizes brain plasticity, in which "general intelligence reflects individual differences in the efficiency and flexibility of brain networks" [14] and "the capacity to integrate information across the brain as a whole". [14] According to this view, "crystallized intelligence" involves the ability to rapidly access existing representations of knowledge and experience while "fluid intelligence" involves the ability to solve novel problems in ways that are adaptive and flexible. [14] [39]
Barbey's Decision Neuroscience Laboratory is supported by large-scale private and federal research grants and contracts, including the Air Force Research Laboratory (AFRL), [6] President Obama's White House BRAIN Initiative, [40] the Director of National Intelligence's research agency, IARPA, [41] and contracts for $10 million from Defense Advanced Research Projects Agency (DARPA) for the study of individual optimization of human performance in the U.S. military using artificial intelligence.

Cognitive neuroscience is the scientific field that is concerned with the study of the biological processes and aspects that underlie cognition, with a specific focus on the neural connections in the brain which are involved in mental processes. It addresses the questions of how cognitive activities are affected or controlled by neural circuits in the brain. Cognitive neuroscience is a branch of both neuroscience and psychology, overlapping with disciplines such as behavioral neuroscience, cognitive psychology, physiological psychology and affective neuroscience. Cognitive neuroscience relies upon theories in cognitive science coupled with evidence from neurobiology, and computational modeling.
The amygdala is a paired nuclear complex present in the cerebral hemispheres of vertebrates. It is considered part of the limbic system. In primates, it is located medially within the temporal lobes. It consists of many nuclei, each made up of further subnuclei. The subdivision most commonly made is into the basolateral, central, cortical, and medial nuclei together with the intercalated cell clusters. The amygdala has a primary role in the processing of memory, decision-making, and emotional responses. The amygdala was first identified and named by Karl Friedrich Burdach in 1822.
Brodmann area 9, or BA9, refers to a cytoarchitecturally defined portion of the frontal cortex in the brain of humans and other primates. Its cytoarchitecture is referred to as granular due to the concentration of granule cells in layer IV. It contributes to the dorsolateral and medial prefrontal cortex.
Behavioral neuroscience, also known as biological psychology, biopsychology, or psychobiology, is the application of the principles of biology to the study of physiological, genetic, and developmental mechanisms of behavior in humans and other animals.
Neuroscience and intelligence refers to the various neurological factors that are partly responsible for the variation of intelligence within species or between different species. A large amount of research in this area has been focused on the neural basis of human intelligence. Historic approaches to studying the neuroscience of intelligence consisted of correlating external head parameters, for example head circumference, to intelligence. Post-mortem measures of brain weight and brain volume have also been used. More recent methodologies focus on examining correlates of intelligence within the living brain using techniques such as magnetic resonance imaging (MRI), functional MRI (fMRI), electroencephalography (EEG), positron emission tomography and other non-invasive measures of brain structure and activity.
The insular cortex is a portion of the cerebral cortex folded deep within the lateral sulcus within each hemisphere of the mammalian brain.
In psycholinguistics, language processing refers to the way humans use words to communicate ideas and feelings, and how such communications are processed and understood. Language processing is considered to be a uniquely human ability that is not produced with the same grammatical understanding or systematicity in even human's closest primate relatives.
Neuroplasticity, also known as neural plasticity or brain plasticity, is the ability of neural networks in the brain to change through growth and reorganization. It is when the brain is rewired to function in some way that differs from how it previously functioned. These changes range from individual neuron pathways making new connections, to systematic adjustments like cortical remapping or neural oscillation. Other forms of neuroplasticity include homologous area adaptation, cross modal reassignment, map expansion, and compensatory masquerade. Examples of neuroplasticity include circuit and network changes that result from learning a new ability, information acquisition, environmental influences, pregnancy, caloric intake, practice/training, and psychological stress.
Retinotopy is the mapping of visual input from the retina to neurons, particularly those neurons within the visual stream. For clarity, 'retinotopy' can be replaced with 'retinal mapping', and 'retinotopic' with 'retinally mapped'.
Richard J. Haier is an American psychologist who has researched a neural basis for human intelligence, psychometrics, general intelligence, and sex and intelligence.
Theresa A. Jones is a researcher and professor at the University of Texas at Austin and the Institute for Neuroscience. Her interests are in neural plasticity across the lifespan, motor skill learning, mechanisms of brain and behavioral adaptation to brain damage, and glial-neuronal interactions. Her research is on the brain changes following stroke, in particular rehabilitation strategies and the brain changes associated with them. She primarily tests rats and uses the Endothelin-1 stroke model. Her most recent work has expanded into the field of microstimulation mapping of the rat cortex.
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain. The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans. It also plays a role in the inhibition of emotional responses, and in the process of decision-making and self-control. It is also involved in the cognitive evaluation of morality.
The dorsolateral prefrontal cortex is an area in the prefrontal cortex of the primate brain. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts into adulthood. The DLPFC is not an anatomical structure, but rather a functional one. It lies in the middle frontal gyrus of humans. In macaque monkeys, it is around the principal sulcus. Other sources consider that DLPFC is attributed anatomically to BA 9 and 46 and BA 8, 9 and 10.
April A. Benasich is an American neuroscientist. She is the Elizabeth H. Solomon Professor of Developmental Cognitive Neuroscience, director of the Infancy Studies Laboratory at the Center for Molecular and Behavioral Neuroscience, and director of the Carter Center for Neurocognitive Research and Professor of Neuroscience at Rutgers University. She is also a principal investigator within the National Science Foundation-funded Temporal Dynamics of Learning Center headquartered at the University of California, San Diego’s Institute for Neural Computation.
The parieto-frontal integration theory (P-FIT) considers intelligence to relate to how well different brain regions integrate to form intelligent behaviors. The theory proposes that large scale brain networks connect brain regions, including regions within frontal, parietal, temporal, and cingulate cortices, underlie the biological basis of human intelligence. These regions, which overlap significantly with the task-positive network, allow the brain to communicate and exchange information efficiently with one another. Support for this theory is primarily based on neuroimaging evidence, with support from lesion studies. The P-FIT is influential in that it explains the majority of current neuroimaging findings, as well as increasing empirical support for cognition being the result of large-scale brain networks, rather than numerous domain-specific processes or modules. A 2010 review of the neuroscience of intelligence described P-FIT as "the best available answer to the question of where in the brain intelligence resides".

He is a professor of psychology at Stanford University, associate director of Stanford Data Science, member of the Stanford Neuroscience Institute and director of the Stanford Center for Reproducible Neuroscience and the SDS Center for Open and Reproducible Science.
Neuromorality is an emerging field of neuroscience that studies the connection between morality and neuronal function. Scientists use fMRI and psychological assessment together to investigate the neural basis of moral cognition and behavior. Evidence shows that the central hub of morality is the prefrontal cortex guiding activity to other nodes of the neuromoral network. A spectrum of functional characteristics within this network to give rise to both altruistic and psychopathological behavior. Evidence from the investigation of neuromorality has applications in both clinical neuropsychiatry and forensic neuropsychiatry.
Arthur F. Kramer is an academic, research scientist, and administrator in cognitive and brain health. The majority of his career has been spent at the Beckman Institute for Advanced Science and Technology, which he helped to establish at the University of Illinois in 1989. As of May 2, 2016, Kramer became senior vice provost for research and graduate education at Northeastern University in Boston, Massachusetts.
Social cognitive neuroscience is the scientific study of the biological processes underpinning social cognition. Specifically, it uses the tools of neuroscience to study "the mental mechanisms that create, frame, regulate, and respond to our experience of the social world". Social cognitive neuroscience uses the epistemological foundations of cognitive neuroscience, and is closely related to social neuroscience. Social cognitive neuroscience employs human neuroimaging, typically using functional magnetic resonance imaging (fMRI). Human brain stimulation techniques such as transcranial magnetic stimulation and transcranial direct-current stimulation are also used. In nonhuman animals, direct electrophysiological recordings and electrical stimulation of single cells and neuronal populations are utilized for investigating lower-level social cognitive processes.
