ERP C250 shows the elderly (cognitively normal, Alzheimer's disease) store more stimuli in short-term memory than Young Adults do
2016, Clinical NeurophysiologyCitation Excerpt :When manipulated by a cognitive task with separable task conditions, ERPs and their underlying components can provide direct, quantitative brain indices of abstract cognitive processes. The behavior of ERP components under varied task conditions has been related to memory processes (Chapman et al., 1978a, 1981; Friedman et al., 1978; Ruchkin et al., 1990; Begleiter et al., 1993; Polich, 2007; Rugg and Curran, 2007; Fukuda et al., 2010), recognition and familiarity (Pfütze et al., 2002; Trenner et al., 2004; Morgan et al., 2008), semantic meaning (Chapman et al., 1978b), stimulus expectancy (Walter et al., 1964; Arbel et al., 2011), executive functioning (Begleiter and Porjesz, 1975), and stimulus relevance (Chapman and Bragdon, 1964; Chapman, 1965; Chapman et al., 2013a), among others. ERP components have also proven useful in measuring age-related versus dementia-related changes in cognition and memory (Chapman et al., 2007, 2011; Missonnier et al., 2007; Rossini et al., 2007; Jackson and Snyder, 2008; Olichney et al., 2008; Cespón et al., 2013; Friedman, 2013).
Infant visual attention and object recognition
2015, Behavioural Brain ResearchCitation Excerpt :Most of these models propose that the hippocampus and surrounding areas of medial temporal lobe are associated with novelty preferences and likely play a key role in recognition memory in infancy (e.g., [20,27,47,64,65,94]). These proposals are largely influenced by electrophysiological recordings with nonhuman primates and neuroimaging studies with adults indicating the presence of a medial temporal lobe circuit involved in recognition memory processes, which includes: the hippocampus and parahippocampal cortex; entorhinal cortex and perirhinal cortices; and additionally the visual area TE [54,55,57,66–72]. However, some authors have concluded that although the hippocampus and other medial temporal areas are functional in early infancy and likely play a role in early recognition memory, this early responsiveness to novelty may be a form of implicit or pre-explicit memory which does not mature into explicit memory until at least 8–12 months of age (e.g., [65,73]; but see, [3]).
Memory timeline: Brain ERP C250 (not P300) is an early biomarker of short-term storage
2015, Brain ResearchCitation Excerpt :However, how and when items are stored immediately after initial sensory processing is not well-defined. While retrieval is an important aspect, the processes by which stimuli are first transferred from fleeting sensory registers (Begleiter et al., 1993; Chapman et al., 1981; Dick, 1974; Sperling, 1960) into a less transient short-term memory store is equally important and often over-looked. This step, where pertinent information is identified and preserved at least for a short time, is essential in successful problem-solving.
Brain ERP components predict which individuals progress to Alzheimer's disease and which do not
2011, Neurobiology of AgingCitation Excerpt :Our research has developed methods with cognitive ERPs that are sufficiently robust to predict MCI individuals who will develop AD with associated probability of progression for each individual. Brain ERP components related to memory (Düzel et al., 1999; Farah et al., 1988; Missonnier et al., 2003, 2004), vision (Begleiter et al., 1993, 1995; Friedman et al., 1981), and stimulus expectations (Donchin, 1981; Hagen et al., 2006) may be useful in understanding the cognitive deterioration seen in some MCI patients as they progress to AD. ERP components have been used to discriminate between normal aging and AD (Chapman et al., 2007), and it has been reported that ERPs may have important predictive power in measuring degeneration from MCI to AD (Missonnier et al., 2005, 2007; Olichney et al., 2002, 2008).
Brain event-related potentials: Diagnosing early-stage Alzheimer's disease
2007, Neurobiology of AgingCitation Excerpt :C145 may reflect perceptual processing of the stimuli [31], suggesting that very early aspects of neural processing may be affected in AD. C250 is the ERP component we have called the “Storage” component, because it has a larger amplitude when a stimulus is stored in short-term memory [2,9,10]. Finding that the median C250 amplitude is smaller for the AD group than the Control group suggests that AD deficits may include storage in short-term memory.
