Our ability to focus attention on task-relevant information and ignore distractions is reflected by differential enhancement suppression of neural activity in sensory cortex (i.e., top-down modulation). Such selective, goal-directed modulation may be intimately related memory, such that the biases likelihood successfully maintaining relevant limiting interference from irrelevant stimuli. Despite recent studies elucidating mechanistic overlap between relationship visual processing during...
Normal aging is associated with a degradation of perceptual abilities and decline in higher-level cognitive functions, notably working memory. To remediate age-related deficits, training programs are increasingly being developed. However, it not yet definitively established if, by what mechanisms, ameliorates effects aging. Furthermore, major factor impeding the success frequent failure to transfer benefits untrained abilities. Here, we offer first evidence direct transfer-of-benefits from...
Hexanucleotide repeat expansions in
Temporal cues guide attentional resources toward relevant points in time, resulting optimized behavioral performance. Although deficits aspects of attention have been documented older adults, it remains unknown whether the critical ability to orient time is affected by normal aging. To address this, younger and adults participated a temporally cued target–response experiment while electroencephalographic data were recorded. Three conditions (one detection two discrimination tasks) used...
Expectations generated by predictive cues increase the efficiency of perceptual processing for complex stimuli (e.g., faces, scenes); however, impact this has on working memory (WM) and long-term (LTM) not yet been investigated. Here, healthy young adults performed delayed-recognition tasks that differed only in stimulus category expectations, while behavioral functional magnetic resonance imaging data were collected. Univariate functional-connectivity analyses used to examine...
The aim of this study was to explore the role attention in pulse and meter perception using complex rhythms. We used a selective paradigm which participants attended either auditory rhythm or visually presented word list. Performance on reproduction task gauge whether were attending appropriate stimulus. hypothesized that rhythms - contain no energy at frequency would lead activations motor areas involved perception. Moreover, because multiple repetitions are needed perceive pulse,...
Abstract Musical instrument training has been linked to improved academic and cognitive abilities in children, but it remains unclear why this occurs. Moreover, access is not always feasible, thereby leaving less fortunate children without opportunity benefit from such training. Although music‐based video games may be more accessible a broader population, research lacking regarding their benefits on performance. To address gap, we assessed custom‐designed, digital rhythm game as proxy for...
Noninvasive transcranial electrical stimulation (tES) research has been plagued with inconsistent effects. Recent work suggested neuroanatomical and neurophysiological variability may alter tES efficacy. However, direct evidence is limited.We have previously replicated effects of alternating current (tACS) on improving multitasking ability in young adults. Here, we attempt to assess whether these parameters comparable older adults (aged 60-80 years), which a population known greater...
Temporal orienting of attention plays an important role in our day-to-day lives and can use timing information from exogenous or endogenous sources. Yet, it is unclear what neural mechanisms give rise to temporal attention, debated whether both forms share a common source. Here, older adult nonmusicians ( N = 47, 24 female) were randomized undergo 8 weeks either rhythm training, which places demands on word search training as control. The goal was assess (1) the basis (2) training-induced...
Temporal expectancy is thought to play a fundamental role in the perception of rhythm. This review summarizes recent studies that investigated rhythmic by recording neuroelectric activity with high temporal resolution during presentation patterns. Prior event-related brain potential (ERP) have uncovered auditory evoked responses reflect detection onsets, offsets, sustains, and abrupt changes acoustic properties such as frequency, intensity, spectrum, addition indexing higher-order processes...
Working memory (WM) performance is impaired by the presence of external interference. Accordingly, more efficient processing intervening stimuli with practice may lead to enhanced WM performance. To explore role on impact that interference has performance, we studied young adults electroencephalographic (EEG) recordings as they performed three motion-direction, delayed-recognition tasks. One task was presented without interference, whereas two tasks introduced different types during interval...
Multitasking is associated with the generation of stimulus-locked theta (4-7 Hz) oscillations arising from prefrontal cortex (PFC). Transcranial alternating current stimulation (tACS) a non-invasive brain technique that influences endogenous oscillations. Here, we investigate whether applying within frequency band would affect multitasking performance, and explore tACS effects on neurophysiological measures. Brief runs bilateral PFC theta-tACS were applied while participants engaged in...
A frontoparietal network has long been implicated in top-down control of attention. Recent studies have suggested that this might communicate through coherence the alpha band. Here we aimed to test effect coherent (8-12 Hz) stimulation on network. To end, recorded behavioral performance and electroencephalography (EEG) data while participants were engaged a spatial attention task. Furthermore, received transcranial alternating current (tACS) over right frontal parietal cortex, which...
Alzheimers disease (AD) presents a critical global health challenge, with current therapies offering limited efficacy and safety in halting progression. Gamma sensory stimulation (GSS) has emerged as promising non-invasive neuromodulation technique that enhances gamma neural synchrony, potentially counteracting AD pathology by reducing neuroinflammation, promoting glymphatic clearance, improving synaptic plasticity. However, existing GSS delivery methods rely on simplistic stimuli lack user...
