• amplitude
  • Changes in the amplitude of P300 [ Time Frame: 15 min after and 120 min after the 1st tDCS, 15 min after and 120 min after the 5st tDCS, and at the follow up 1 week after the 5th tDCS. (clinicaltrials.gov)
  • However, uncertainty about the relationship between N1 amplitude and attention was resolved by Haider, Spong, and Lindsley's (1964) groundbreaking study in which levels of attention were found to systematically relate to variation in the amplitude of the N1. (wikipedia.org)
  • N200
  • With the rapid proliferation of high-density EEG methods, and interdisciplinary interest in its application as a prognostic, diagnostic, and investigative tool, an understanding of the underpinnings of P300 and N200 physiology may support its application to both the basic neuroscience and clinical medical settings. (medsci.org)
  • sensory
  • Neuroprosthetics is an area of neuroscience concerned with neural prostheses, that is, using artificial devices to replace the function of impaired nervous systems and brain related problems, or of sensory organs. (wikipedia.org)
  • elicit
  • Generally speaking, improbable events will elicit a P3b, and the less probable the event, the larger the P3b. (wikipedia.org)
  • However, in order to elicit a P3b, the improbable event must be related to the task at hand in some way (for example, the improbable event could be an infrequent target letter in a stream of letters, to which a subject might respond with a button press). (wikipedia.org)
  • reaction time
  • Participants (n = 58) were assessed on antisaccade reaction time (RT) to examine executive-related oculomotor control and self-reported physical activity (PA) at pre-intervention (V0), post-intervention (V1), and 52-weeks follow-up (V2). (iospress.com)
  • Visual
  • P300-based acuity estimation with optotypes may thus be particularly useful with visual impairments that differentially affect grating and optotype acuity. (arvojournals.org)
  • 8 Visual evoked potential recordings, often implemented in the form of sweep VEPs, can demonstrate that signals from the eyes reach the cortex and have successfully been used to estimate visual acuities. (arvojournals.org)
  • In line with this hypothesis, we suggest that, while the classical explanation of reduced visual processing of emotions in ADI focuses on emotional areas' [amygdala, orbitofrontal cortex (OFC)] dysfunction, this impairment might also be related to alterations of early visual processing and/or connectivity between visual and emotional areas. (frontiersin.org)
  • The M100 discussed here is the magnetic equivalent of the visual N1 potential-an event-related potential linked to visual processing and attention. (wikipedia.org)
  • participants
  • Chapman and Bragdon speculated that this differential response to the numbers, which came to be known as the P300 response, resulted from the fact that the numbers were meaningful to the participants, based on the task that they were asked to perform. (wikipedia.org)
  • cognition
  • Treatment-related sedation and its effect on cognition are a major concern. (aappublications.org)
  • Studies in germ-free animals and in animals exposed to pathogenic microbial infections, antibiotics, probiotics, or fecal microbiota transplantation suggest … a role for the gut microbiota in host cognition or AD-related pathogenesis. (iospress.com)
  • These early studies encouraged the use of ERP methods to study cognition and provided a foundation for the extensive work on the P300 in the decades that followed. (wikipedia.org)
  • thought
  • A form of prediction is also thought to occur in some types of lexical priming, a phenomenon whereby a word becomes easier to process if it is preceded by a related word. (wikipedia.org)
  • mechanism
  • From an evolutionary perspective, this mechanism is useful in reacting quickly to events that call for immediate action. (wikipedia.org)
  • Influences
  • Their eye movements are recorded, allowing the experimenter to understand how language influences eye movements toward pictures related to the content of the sentence. (wikipedia.org)
  • include
  • These major conferences occur every other year and include activities such as keynote lectures, workshops, posters, satellite events, and demonstrations. (wikipedia.org)
  • Computational models of eye movements during reading, which model data related to word predictability, include Reichle and colleagues' E-Z Reader model and Engbert and colleagues' SWIFT model. (wikipedia.org)
  • people
  • Ginkgo may also be helpful for improving normal age-related memory loss, and even for enhancing mental function in younger people. (doctors-hospital.net)
  • Set against these positive findings is a large (214 people) 24-week study that found no benefit in ordinary age-related memory loss. (doctors-hospital.net)
  • function
  • Thresholds were estimated by fitting a sigmoid curve to P300 amplitudes as a function of Landolt C size or grating coarseness, respectively. (arvojournals.org)
  • international
  • Grants can be used for international conference travel or if a conference is directly related to the proposed project and if college travel funds are not available. (drake.edu)
