A new study shows that a potential treatment for Alzheimer's disease, sargramostim, improves cognitive function in people with Down syndrome and normal aging mice. The drug reverses learning and memory deficits, nerve cell loss, and brain abnormalities in mouse models of Down syndrome and aging.
Studies investigating the impact of memory on perception aim to understand how our brains alter sensory information, enabling us to conserve energy on expected stimuli. This research may lead to advancements in treating PTSD by analyzing communication between brain regions affected by trauma.
Researchers from Washington State University found that the optimal time of day for different cognitive tasks does not differ based on task type. Participants who felt sleepy should consider postponing important tasks until a later time to avoid performance impairment.
Researchers find that familiar stimuli quiet down brain activity in fruit flies, allowing for clearer processing of specific odors. This mechanism applies to neural circuits in other animals, including humans, and is essential for filtering out distractions to focus on relevant information.
A study published in Trends in Cognitive Sciences found that older adults tend to store irrelevant information, making it harder to remember specific details. This can lead to a 'flood' of information, but also benefits like improved prior knowledge utilization and decision-making.
A recent study at Rockefeller University reveals that the FMRP protein plays a dual role in regulating synaptic connections between neurons. It controls protein production in dendrites to strengthen connections, while also regulating gene expression in cell bodies to maintain overall neuron state.
Researchers found that males keep track of the order of their songs and how often each one is sung for up to 30 minutes. This complex behavior allows them to curate both their current playlist and the next one, with variations in song order and repeats.
A study published in iScience reveals that distorted perception of bodily self-consciousness can be predicted by different kinds of memories. The researchers found that the recovery of body ownership was associated with a fast memory process, while agency recovery was mainly linked to a slow memory process.
The study found that memories of objects from stressful situations rely on similar brain activity as memories of the stress trigger itself. This suggests that the mechanism reinforcing emotional memories is rooted in the neural link between important aspects of the episode and the stress trigger.
A new study by University of Leicester neuroscientists argues that the way humans store memories is key to our superior intelligence. Contrary to long-held beliefs, the same group of neurons stores all memories, enabling abstract thinking and cognitive abilities unique to humans.
A recent study by Aarhus University researchers reveals that citizens contribute significantly to the spread of negative information about politicians, leading to increased mistrust. This phenomenon is rooted in humans' innate psychological tendency to prioritize self-interest over political substance.
Researchers used repetitive transcranial magnetic stimulation to increase functional connectivity of a neural network implicated in memory. The study, published in eNeuro, confirms the effectiveness of this technique for experimental and clinical applications.
Researchers discovered that people tend to forget passwords less frequently when they are used more often, according to a Rutgers University-led study. The study's findings suggest that password systems could be designed to encourage users to log in regularly, improving password retention.
Researchers at UCI have identified an important aspect of the brain's navigational system, revealing how rodents process and reactivate spatial information. This new knowledge has high accuracy predictions for animal speed and direction.
A study of 154 individuals with near-death experiences found that while common phenomena like feeling peacefulness and seeing a bright light occur frequently, the order of appearance varies greatly between participants. The most commonly reported sequence was out-of-body experience followed by a tunnel, bright light, and finally peace.
A new global atlas reveals that the Milky Way is only visible from 33% of the world's population, with 80% of Americans experiencing light-polluted nights. This widespread issue affects not only human connections to nature but also confuses wildlife and exposes them to fatal consequences.
The ecancermedicalscience Special Issue celebrates the legacy of Dr. Mario Sideri, a pioneer in preventive gynecology. The nine articles cover topics such as screening techniques, HPV vaccine use, and E6/E7 mRNA testing for cervical intraepithelial disease.
A recent study published in the Journal of Experimental Medicine found that humans can build up memory T cell numbers over time without sacrificing old ones, unlike previous studies on mice that suggested space limitations. The discovery has significant implications for understanding human immune responses and potential treatments.
A study published in ACS' Journal of Agricultural and Food Chemistry found that blueberry juice supplementation improved learning and memory tests in volunteers aged 70-72. The researchers suggested that consistent blueberry consumption may offer an approach to mitigate neurodegeneration.
Professor Gregory Stephanopoulos has been awarded the 2009 Amgen Biochemical Engineering Award for his outstanding contributions to metabolic engineering. He has made significant contributions to the field of biochemical engineering, including the development of microbial cells for the production of fuels and chemicals.
Researcher Elizabeth Loftus found that people can be led to believe they got sick as children from specific unhealthy foods, resulting in reduced appeal as adults. Participants showed a similar tendency to avoid the food after believing they had a negative experience.
A recent study by Christian Larsen and colleagues reveals that a specific threshold of memory cells is necessary to promote rejection, while CD8+ central memory cells mediate rejection. The authors suggest testing for potential cellular sensitization against donors prior to tolerance protocols to increase human transplantation success.
