“…Developments in imaging technology are accompanied by continuing improvements in analysis methods. For example, two-source dipole modelling approaches have been proposed (Richards, 2004;Johnson et al, 2001) which can be based on independent and principal components analyses to improve accuracy of the source localisation of ERP signals. In order to accomplish this, investigators require head models appropriate for normal infants, which should include conductivity and volumetric estimates for scalp, skull, and liquid.…”

Recent advances in cognitive neuroscience have allowed us to begin investigating the development of both structure and function in the infant brain. However, despite the rapid evolution of technology, surprisingly few studies have examined the intersection between brain and behaviour over the first years of life. Even fewer have done so in the context of a particular research question. This paper aims to provide an overview of four domains that have been studied using techniques amenable to elucidating the brain/behaviour interface: language, face processing, object permanence, and joint attention, with particular emphasis on studies focusing on early development. The importance of the unique role of development and the interplay between structure and function is stressed throughout. It is hoped that this review will serve as a catalyst for further thinking about the substantial gaps in our understanding of the relationship between brain and behaviour across development. Further, our aim is to provide ideas about candidate brain areas that are likely to be implicated in particular behaviours or cognitive domains.

“…First, ERPs have a good temporal resolution, which enables us to examine the detailed time-course of the gaze processing. Secondly, ERPs are the most feasible way to measure brain activity from awake human infants (de Haan, Johnson & Halit, 2003;Johnson, de Haan, Oliver, Smith, Hatzakis, Tucker & Csibra, 2001). The aim of Experiment 1 was to extend the study of Pelphrey et al (2003) to ERP measurement.…”

Infants are sensitive to the referential information conveyed by others' eye gaze, which could be one of the developmental foundations of theory of mind. To investigate the neural correlates of gaze-object relations, we recorded ERPs from adults and 9-month-old infants while they watched scenes containing gaze shifts either towards or away from the location of a preceding object. In adults, object-incongruent gaze shifts elicited enhanced ERP amplitudes over the occipito-temporal area (N330). In infants, a similar posterior ERP component (N290) was greater for object-incongruent gaze shifts, which suggests that by the age of 9 months infants encode referential information of gaze in a similar way to adults. In addition, in infants we observed an early frontal ERP component ( anterior N200), which showed higher amplitude in response to the perception of object-congruent gaze shifts. This component may reflect fast-track processing of socially relevant information, such as the detection of communicative or informative situations, and could form a developmental foundation for attention sharing, social learning and theory of mind.

“…The examination of auditory event-related potentials (ERPs) is a useful tool of studying cognitive functions in infants because non-invasive methods available for assessing brain psychophysiological functions at this early age are very rare and behavioral methods provide rather limited information of central sensory processing [1]. It has been shown that with the increase of age, infant ERP waveforms gradually become complex.…”

“…In adults, early brain response components, such as P 1 and N 1 components, are thought to be exogenous and are associated with neural activity involved in the lateral lemniscus nuclei, the inferior colliculus and the thalamic nuclei, whereas activations underlying adult P 2 component may involve unspecific projections to auditory cortex. Relatively longer latencies of ERP components are measured in infants and children.…”

Maturation of auditory perceptual and discrimination process within the first two years of life is investigated in healthy infants by examining event-related potentials (ERPs). High-density EEG signals were recorded from the scalp monthly between 3 and 24 months of age. Two types of stimuli (100 vs. 100 Hz for standard stimuli; 100 vs. 300 Hz for deviant stimuli; occurrence rate: 85:15%) were presented using an oddball paradigm. Latencies and amplitudes were compared across development. The results showed that latencies of P 150 , N 250 , P 350 , and N 450 components gradually decreased with increasing age. Amplitudes of the N 250 and P 350 components gradually increased and reached the maximum at 9 months, and then gradually decreased with the increase of age. Mismatch negativity was not obvious at 3 months of age, but was seen at 4-5 months and became robust after 6 months. Robust late positivity was recorded at all ages. These mismatch responses were noticeable in the frontal, central, and parietal areas, and the maximal MMN amplitude distribution gradually moved from the parietal area to the frontal area across the age range. Two important periods-one around 6 months and the other around 9 months are suggested in the maturation of auditory central system. Dynamical changes in the underlying source strengths and orientations may be principal contributors to ERP morphological changes in infants within the first 24 months.
