“…The key point is that only a single brain-wide set of voxels is used for each subject). Increased brain-wide pattern separability was found to correlate with improved behavioural performance in two different tasks, from two different datasets: the /ra/-/la/ task examined in Raizada et al (2010) and a numerical distance-effect task from Holloway et al (2010).…”

Recent years have seen a strong growth of interest in multivariate approaches for analysing brain activity patterns. The primary goal of these approaches is to reveal the information represented in neuronal population codes. Here, we review how these methods have been used to relate neural activity patterns both to stimulus input and to behavioural output and how they might help to explain individual differences in behavioural performance. We examine the neuroscientific interpretation of different types of pattern-information analysis and highlight current challenges and promising future directions for this emerging field. The open challenges that we discuss are as follows: inferring the causal role of pattern information, seeking diagnostic power for functional Magnetic Resonance Imaging (fMRI) at the level of individuals, determining whether observed patterns have real functional significance, finding the structure underlying high-dimensional activation spaces and relating one person's neural patterns to another's.

“…To date a large body of evidence has demonstrated that the intraparietal sulcus (IPS) of the parietal lobe is consistently engaged whenever numerical magnitudes are processed. For instance, modulation of brain activation in the parietal lobe has been found in number comparison (Ansari et al 2005;Holloway et al 2010;Pinel et al 1999Pinel et al , 2001, in the context of calculation (e.g., Grabner et al 2007;Simon et al 2002Simon et al , 2004, in tasks in which the spatial position of a given number on a physical number line has to be estimated ) and in Fig. 4 Mean deviation scores of the HRP and NL condition as a function of "high-numeracy group" and "low-numeracy group" fMRI-Adaptation studies in which the neural signal recovery in response to numerical deviants has been investigated (Holloway et al 2012;Vogel et al 2015).…”

overestimated health risks. A comparison of brain activation between the groups demonstrated that the high-numeracy group expressed larger brain engagement during the health risk condition in regions that are commonly associated with conflict monitoring, decision-making and emotional processing. These results provide initial evidence that individuals with high-numeracy engage regions of the brain to a different extent compared to individuals with low-numeracy.

“…The activity of the angular gyrus is also frequently modulated during number processing [29], and involved in processes working memory [30] and cognition, as the results of linguistic and mathematical competence [31]. Passive viewing and perception of familiar symbols increased activation in the left angular gyrus to a greater extent than passing viewing of unfamiliar symbols did [32], and the left angular gyrus and superior temporal gyri activated more to the symbolic than the nonsymbolic [33]. In addition, ADHD subjects were found significance reduced volume of the right angular gyrus [34], Alzheimer's disease patients showed significant glucose hypometabolism in angular gyrus [35] and multiplayer online role-playing games showed a significantly decreased activations in the angular gyrus [36].…”

The purpose of this study was to compare the hemodynamic changes that occur during Mahjong game play in virtual and real-life settings. Fourteen healthy right-handed men (average age ± standard deviation; 36.7 ± 14.9 years) played: 1) a Mahjong solitaire game on a video console against virtual rivals; 2) a Mahjong game against human opponents without conversation; and 3) a Mahjong game against human opponents with conversation. We measured oxygenated hemoglobin concentration at 44 locations over both hemispheres during Mahjong game play in each setting using near-infrared spectroscopy. The increase in oxygenated hemoglobin concentration at several locations, including Broca's area, the somatosensory cortex, the somatosensory association cortex, the supramarginal gyrus part of Wernicke's area, the primary and auditory association cortex, the angular gyrus part of Wernicke's area, and the associative visual cortex was greater during game play in the real-life settings than during game play in the video game setting. There were no significant differences during game play in real-life settings without and with conversation. Each cortical area correlated with broad or specific areas. The common correlation areas were found at Angular gyrus part of Wernicke's area of left hemisphere during real-life settings without and with conversation, but not during game play in a video game setting. These results suggest that the brain responds differently to game play in real world and virtual world settings, and indicate that comparison of games played in the virtual world and the real world may be an effective model to enhance understanding of the effects of video game on the brain.
