TLDR
Surface splines are mathematical tools for interpolating functions of two variables that are smoother, give more precisely located extrema and converge faster toward the 'true' potential surface when the number of recording electrodes is increased.About:

Spherical splines for scalp potential and current density mapping
TL;DR: Description of mapping methods using spherical splines, both to interpolate scalp potentials (SPs) and to approximate scalp current densities (SCDs) with greater accuracy in areas with few electrodes.

EEG source imaging

TL;DR: It is shown that modern EEG source imaging simultaneously details the temporal and spatial dimensions of brain activity, making it an important and affordable tool to study the properties of cerebral, neural networks in cognitive and clinical neurosciences.

Topographic ERP Analyses: A Step-by-Step Tutorial Review
TL;DR: This tutorial review detail both the rationale for as well as the implementation of a set of analyses of surface-recorded event-related potentials (ERPs) that uses the reference-free spatial information available from high-density electrode montages to render statistical information concerning modulations in response strength, latency, and topography both between and within experimental conditions.

Brain generators implicated in the processing of auditory stimulus deviance: a topographic event-related potential study.
TL;DR: The results showed that, in all cases, the negative wave elicited by the deviant stimuli showed the highest amplitudes over the right hemiscalp irrespective of the ear of stimulation or the direction of attention, and this asymmetric potential distribution could be attributed to the sum of activities of two sets of neural generators.

Dissociation of the neural correlates of implicit and explicit memory
Michael D. Rugg,Ruth E. Mark,Peter Walla,Astrid M. Schloerscheidt,Claire S. Birch,Kevin Allan +5 more
TL;DR: Sc scalp-recorded event-related brain potentials are used to identify neural activity associated with implicit and explicit memory during the performance of a recognition memory task and show that when task and memory contamination effects are eliminated, the neural correlates of explicit and implicit memory differ qualitatively.

Interpolation using surface splines.
TL;DR: A surface spline is a mathematical tool for interpolating a function of two variables as discussed by the authors, which is based upon the small deflection equation of an infinite plate and requires the use of a digital computer.

Brain electrical activity mapping (BEAM): a method for extending the clinical utility of EEG and evoked potential data.
TL;DR: A sensitivity to the functional component of a neurological lesion suggests that BEAM may provide complementary information to the anatomical definition provided by the CT scan, and a method for condensing and summarizing the spatiotemporal information contained in recordings from multiple scalp electrodes is described.

Location of Sources of Evoked Scalp Potentials: Corrections for Skull and Scalp Thicknesses
TL;DR: It is shown that the position of the source in a head modeled by a sphere surrounded by two concentric shells of differing conductivities representing the skull and the scalp can be inferred from source localization calculations made on a homogeneous model.

Scalp distribution of human auditory evoked potentials. II. Evidence for overlapping sources and involvement of auditory cortex.
TL;DR: The scalp distributions of human auditory evoked potentials between 20 and 250 msec were investigated using non-cephalic reference recordings and demonstrate a stable scalp distribution of dipolar form that is consistent with sources in primary auditory cortex on the superior temporal plant near the temporoparietal junction.
