This review presents a critical appraisal of high-quality studies in the field of developmental cognitive neuroscience, focusing on design issues that are critical for establishing effective educational neuroscience. I argue that cognitive neuroscience studies of cognitive development need to respect important experimental constraints. The use of longitudinal and intervention designs is key. The field needs to move beyond simply studying patterns of brain activation to studying brain mechanisms of information encoding and information processing. Indeed, studies at multiple levels of description are required, combining the assessment of individual differences in neural learning, sensory processing, cognitive processing, and children's behavior. Current evidence suggests that the child brain has essentially the same structures as the adult brain, carrying out essentially the same functions via the same mechanisms. This review demonstrates that neural systems that learn the patterns or regularities in environmental input (via statistical learning) can, in principle, acquire complex cognitive structures like language and conceptual knowledge.

Abstract INTRODUCTION Recent developments in the biology of malignant gliomas have demonstrated that glioma cells interact with neurons through both paracrine signaling and electrochemical synapses. Glioma-neuron interactions consequently modulate the excitability of local neuronal circuits, and it is unclear the extent to which glioma-infiltrated cortex can meaningfully participate in neural computations. For example, gliomas may result in a local disorganization of activity that impedes the transient synchronization of neural oscillations. Alternatively, glioma-infiltrated cortex may retain the ability to engage in synchronized activity, in a manner similar to normal-appearing cortex, but exhibit other altered spatiotemporal patterns of activity with subsequent impact on cognitive processing. METHODS Here, we acquired invasive electrophysiologic recordings to sample both normal-appearing and glioma-infiltrated cortex during speech initiation in order to measure language task-related circuit dynamics of IDH-wild-type glioblastoma patients. We then applied an information theoretical framework to directly compare the encoding capacity and decodability of signals arising from these regions. RESULTS We find that glioma-infiltrated cortex engages in synchronous activity during task performance in a manner similar to normal-appearing cortex, but recruits a diffuse spatial network. On a temporal scale, we show that glioma-infiltrated cortex has lower capacity for information encoding when performing nuanced tasks such as speech production of monosyllabic versus polysyllabic words. As a result, temporal decoding strategies for distinguishing monosyllabic from polysyllabic words were feasible for signals arising from normal-appearing cortex, but not from glioma-infiltrated cortex. CONCLUSION These findings inform our understanding of cognitive processing in patients with malignant gliomas and have implications for patient survival, neuromodulation, and prosthetics in patients with malignant gliomas.

Ever since the 1980s, research on the cross-linguistic representation of spatial relations has burgeoned. Surprisingly, however, very little of this work has had any impact on cognitive neuroscience, and most researchers who study the cortical underpinnings of concrete conceptual knowledge have ignored spatial relations completely, preferring to focus on objects and actions instead. Due to this rather stark asymmetry, this chapter has a different organization than the previous two. The first section focuses entirely on cross-linguistic similarities and differences in the grammatical-semantic representation of three main types of spatial relations: topological, projective, and deictic. Then the last section addresses a number of neuroscientific issues, including a review of what has been learned so far about the implementation of these kinds of concepts in the brain, and a discussion of how the typological literature can both inspire and guide future research in this important but relatively neglected area of inquiry.

Functional magnetic resonance imaging studies of developmental disorders and normal cognition that include children are becoming increasingly common and represent part of a newly expanding field of developmental cognitive neuroscience. These studies have illustrated the importance of the process of development in understanding brain mechanisms underlying cognition and including children in the study of the etiology of developmental disorders.
