Touch screen storybooks turn reading into an interactive multimedia experience, with hotspot-activated animations, sound effects, and games. Positive and negative effects of reading multimedia stories have been reported, but the underlying mechanisms which explain how children's learning is affected remain uncertain. The present study examined the effect of storybook format (touch screen and print) on story comprehension, and considered how level of touch screen interactivity (high and low) and shared reading behaviors (cognitive and emotional scaffolding, emotional engagement) might contribute to comprehension...

Alzheimer's disease (AD) is the most common form of dementia that mainly affects the cognitive functions of the aged populations. Trigonella foenum-graecum (L.) (fenugreek), a traditionally well utilized medicinal plant ubiquitously used as one of the main food additive worldwide, is known to have numerous beneficial health effects. Fenugreek seed extract could be able to inhibit the activity of acetylcholinesterase (AChE), a key enzyme involved in the pathogenesis of AD, and further shown to have anti-parkinsonic effect...

Rishikesan Kamaleswaran, Carolyn McGregor
BACKGROUND: Physiological data is derived from electrodes attached directly to patients. Modern patient monitors are capable of sampling data at frequencies in the range of several million bits every hour. Hence the potential for cognitive threat arising from information overload and diminished situational awareness becomes increasingly relevant. A systematic review was conducted to identify novel visual representations of physiologic data that address cognitive, analytic, and monitoring requirements in critical care environments...

: Calcium homeostasis plays a major role in maintaining neuronal function under physiological conditions. Amyloid-β (Aβ) initiates pathological processes that include disruption in intracellular calcium levels, and therefore amelioration of the calcium alteration could serve as an indirect functional indicator of treatment efficacy. Thus, calcium dynamics was used as a measure of functional outcome. We evaluated the effects of the anti-Aβ antibody aducanumab, on calcium homeostasis and plaque clearance in aged Tg2576 mice with in vivo multiphoton imaging...

OBJECTIVE: Parent use of mobile devices (e.g., smartphones, tablets) while around their young children may be associated with fewer or more negative parent-child interactions, but parent perspectives regarding this issue have not been explored. We aimed to understand parent views regarding their mobile device use to identify actionable targets of potential intervention. METHOD: We conducted 35 in-depth semi-structured group and individual interviews with English-speaking caregivers of children 0 to 8 years old, purposively sampled from diverse ethnic backgrounds, educational levels, and employment statuses...

Vaccinations and the controversy around them always go in parallel. We identified four categories blending in various amounts of truth and imagination: history, myths, shams and frauds. Over the years, they have alternated and sometimes transformed into one another. This sharp separation into categories is certainly academic and forced. In fact, the line between these aspects is not clear enough to allow a rigid and well-defined division. Our work starts from the category containing the most truthfulness: history, and goes on to analyze two categories that add fantasy to facts: myths and shams (or better, "old wives' tales")...

Space flight factors (SFF) significantly affect the operating activity of astronauts during deep space missions. Gravitational overloads, hypo-magnetic field and ionizing radiation are the main SFF that perturb the normal activity of the central nervous system (CNS). Acute and chronic CNS risks include alterations in cognitive abilities, reduction of motor functions and behavioural changes. Multiple experimental works have been devoted to the SFF effects on integrative functional activity of the brain; however, the model parameters utilized have not always been ideal and consistent...

The findings of a study by Cahn and Polich (2009) suggests that there is an effect of a meditative state on three event-related potential (ERP) brain markers of "low-level" auditory attention (i.e., acoustic representations in sensory memory) in expert meditators: the N1, the P2, and the P3a. The current study built on these findings by examining trait and state effects of meditation on the passive auditory mismatch negativity (MMN), N1, and P2 ERPs. We found that the MMN was significantly larger in meditators than non-meditators regardless of whether they were meditating or not (a trait effect), and that N1 amplitude was significantly attenuated during meditation in non-meditators but not expert meditators (an interaction between trait and state)...

BACKGROUND: Research on cooperative behavior and the social brain exists, but little research has focused on real-time motor cooperative behavior and its neural correlates. In this proof of concept study, we explored the conceptual notion of shared and complementary mental models through EEG mapping of two brains performing a real-world interactive motor task of increasing difficulty. We used the recently introduced participative "juggling paradigm," and collected neuro-physiological and psycho-social data...

CONTEXT: Fidelity is widely viewed as an important element of simulation instructional design based on its purported relationship with transfer of learning. However, higher levels of fidelity may increase task complexity to a point at which novices' cognitive resources become overloaded. OBJECTIVES: In this experiment, we investigate the effects of variations in task complexity on novices' cognitive load and learning during simulation-based procedural skills training...

Mitochondrial abnormalities are well-known to cause cognitive decline. However, the underlying molecular basis of mitochondria-associated neuronal and synaptic dysfunction in the diabetic brain remains unclear. Here, using a mitochondrial single channel patch clamp and cyclophilin D (CypD)-deficient mice (Ppif (-/-)) with streptozotocin (STZ)-induced diabetes, we observed an increase in the probability of Ca(2+)-induced mitochondrial permeability transition pore (mPTP) opening in brain mitochondria of diabetic mice, which was further confirmed by mitochondrial swelling and cytochrome c release induced by Ca(2+) overload...

Aging is associated to cognitive decline and susceptibility to neuron death, two processes related recently to subcellular Ca(2+) homeostasis. Memory storage relies on mushroom spines stability that depends on store-operated Ca(2+) entry (SOCE). In addition, Ca(2+) transfer from endoplasmic reticulum (ER) to mitochondria sustains energy production but mitochondrial Ca(2+) overload promotes apoptosis. We have addressed whether SOCE and ER-mitochondria Ca(2+) transfer are influenced by culture time in long-term cultures of rat hippocampal neurons, a model of neuronal aging...

BACKGROUND: Combining strategies and techniques from different therapeutic approaches is a common procedure in routine mental health practice. It has been claimed that the integration of systemic brief therapies offers useful psychotherapeutic alternatives, especially in our overloaded public mental health services. However, this claim has rarely been put to the test, and comparison with well-established empirically-based treatments has been scarce. METHOD: Of 419 patients referred to an Adult Ambulatory Mental Health Service, 212 were allocated to Cognitive-Behavioral Therapy (CBT), and 207 to an integrative Brief Systemic Therapy (BST)...

Iron-overload can cause cognitive impairment due to blood-brain barrier (BBB) breakdown and brain mitochondrial dysfunction. Although deferiprone (DFP) has been shown to exert neuroprotection, the head-to-head comparison among iron chelators used clinically on brain iron-overload has not been investigated. Moreover, since antioxidant has been shown to be beneficial in iron-overload condition, its combined effect with iron chelator has not been tested. Therefore, the hypothesis is that all chelators provide neuroprotection under iron-overload condition, and that a combination of an iron chelator with an antioxidant has greater efficacy than monotherapy...

This perspective article builds upon the theory of local thinking in interpretation and prediction of consumer behavior in a contemporary world of information overload. It is shown that even informed and socially and environmentally responsible consumers (consumers 3.0) exhibit selective recall, limited attention, and bounded search in the perception and interpretation of price and quality of purchases. Their decisions fall into local cognitive frames, which specifically focus attention only on a narrow structure and content of the choice...

Today, we live in a world of 'information overload' which demands high level of knowledge-based work. However, advances in computer hardware and software have opened possibilities to automate 'routine cognitive tasks' for knowledge processing. Engineering intelligent software systems that can process large data sets using unstructured commands and subtle judgments and have the ability to learn 'on the fly' are a significant step towards automation of knowledge work. The applications of this technology for high throughput genomic analysis, database updating, reporting clinically significant variants, and diagnostic imaging purposes are explored using case studies...
