“…In contrast, an increase is alpha power specifically was seen for the spatial reproduction task in the posterior region of interest. More generally, these findings provide continuing support for the involvement of theta, alpha and beta oscillations in the measurement of temporal and spatial intervals (Bischof and Boulanger, 2003;Hsieh, Ekstrom, & Ranganath, 2011;Liang, Starrett, & Ekstrom, 2018;Samaha et al, 2015;Vilhelmsen et al, 2015;Kononowicz & Rijn, 2015;Kulashekhar, Pekkola, Palva, & Palva, 2016;Javadi, et al 2019).…”

The perception and measurement of spatial and temporal dimensions have been widely studied. However, whether these two dimensions are processed independently is still being debated. Additionally, whether EEG components are uniquely associated with time or space, or whether they reflects a more general measure of magnitude remains unknown. While undergoing EEG, subjects traveled a randomly predetermined spatial or temporal interval and were then instructed to reproduce the interval traveled. In the task, the subject's travel speed varied for the estimation and reproduction phases of each trial, so that one dimension could not inform the other. Behaviorally, subject performance was more variable when reproducing time than space, but overall, just as accurate; notably, behavior was not correlated between tasks. EEG data revealed during estimation the contingent negative variation (CNV) tracked the probability of the upcoming interval, regardless of dimension. However, during reproduction, the CNV exclusively oriented to the upcoming temporal interval at the start of reproduction. Further, a dissociation between relatively early frontal beta and late posterior alpha oscillations was observed for time and space reproduction, respectively. Our findings indicate that time and space are neurally separable dimensions, yet are hierarchically organized across task contexts within the CNV signal.

“…In recent years, there has been an increase in behavioral work querying aspects of navigation using a hybrid VR-real world approach, where natural motion is yoked to movements within virtual environments (e.g., Chen X. et al, 2015 ; Chen et al, 2017 ; He and McNamara, 2018 ; Sjolund et al, 2018 ), which more closely parallels work carried out with rats. However, this hybrid approach is not generally combined with imaging techniques (although see Ehinger et al, 2014 ; Gehrke et al, 2018 ; Liang et al, 2018 ), so from a theoretical perspective, how the brain integrates sensory perception of environmental features and self-motion information from visual (optic flow), vestibular, proprioceptive and motor systems to support spatial navigation in humans remains an open question. VR will remain a powerful method for studying neural activity during active navigation, as it facilitates manipulations that are difficult or impossible to realize in the real-world.…”

A central question in neuroscience and psychology is how the mammalian brain represents the outside world and enables interaction with it. Significant progress on this question has been made in the domain of spatial cognition, where a consistent network of brain regions that represent external space has been identified in both humans and rodents. In rodents, much of the work to date has been done in situations where the animal is free to move about naturally. By contrast, the majority of work carried out to date in humans is static, due to limitations imposed by traditional laboratory based imaging techniques. In recent years, significant progress has been made in bridging the gap between animal and human work by employing virtual reality (VR) technology to simulate aspects of real-world navigation. Despite this progress, the VR studies often fail to fully simulate important aspects of real-world navigation, where information derived from self-motion is integrated with representations of environmental features and task goals. In the current review article, we provide a brief overview of animal and human imaging work to date, focusing on commonalties and differences in findings across species. Following on from this we discuss VR studies of spatial cognition, outlining limitations and developments, before introducing mobile brain imaging techniques and describe technical challenges and solutions for real-world recording. Finally, we discuss how these advances in mobile brain imaging technology, provide an unprecedented opportunity to illuminate how the brain represents complex multifaceted information during naturalistic navigation.

“…For example, eye closure induces alpha power increases both at occipital sites and in hippocampus (Geller et al, 2014). Our current results would suggest differing roles in navigation for frontal midline theta (4-8 Hz) and occipital alpha (8-12 Hz), which were both found relevant to movement (Liang, Starrett, & Ekstrom, 2018), and frontal midline theta and occipital alpha oscillations can cooperate to support task-dependent spatial or temporal processing. Therefore, a helpful next step would be to determine how these signals coordinate between hippocampus and cortex in our task using ECoG.…”

Judging how far something is and how long it takes to get there are critical to memory and navigation. Yet, the neural codes for spatial and temporal information remain unclear, particularly how and whether neural oscillations might be important for such codes. To address these issues, participants traveled through teleporters in a virtual town while we simultaneously recorded scalp EEG. Participants judged the distance and time spent inside the teleporter. Our findings suggest that alpha power relates to distance judgments while frontal theta power relates to temporal judgments. In contrast, changes in alpha frequency and beta power indexed both spatial and temporal judgments. We also found evidence for fine-grained temporal coding and an effect of past trials on temporal but not spatial judgments. Together, these findings support partially independent coding schemes for spatial and temporal information, and suggest that low-frequency oscillations play important roles in coding both space and time.
