Cognition is a concept used in different ways by different disciplines, but is generally accepted to mean the process of thought. For example, in psychology and cognitive science it refers to an information processing view of an individual's psychological functions.
Slow waves that usually only occur in the brain during sleep are also present during wakefulness in people with epilepsy and may protect against increased brain excitability associated with the condition, finds a new study led by researchers at UCL.
The longer a person has type 2 diabetes, the more likely they may be to experience changes in brain structure, a Michigan Medicine study finds.
Cognitive deficits accompany mood disorders and other psychiatric conditions, often with debilitating effects.
People with dementia have protein build-up in astrocytes that may trigger abnormal antiviral activity and memory loss, according to a preclinical study by a team of Weill Cornell Medicine investigators.
Long thought of as "brain glue," the star-shaped cells called astrocytes-;members of a family of cells found in the central nervous system called glial that help regulate blood flow, synaptic activity, keep neurons healthy, and play an important role in breathing.
According to the World Health Organization, enterotoxigenic Escherichia coli (ETEC) bacteria are the most common cause of traveler’s diarrhea and cause the greatest number of known community-acquired cases of childhood diarrhea in the developing world.
A tiny worm called the C. elegans is enabling scientists to explore the emerging theory that Parkinson's disease starts in the gut.
Twenty years ago, following the initial sequencing of the human genome, geneticists started carrying out extensive genome-wide association studies to find genomic regions connected to human disease.
The Neurobiology of miRNA team, headed by Davide De Pietri Tonelli of the Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology), established a link between a family of small RNA molecules known as piRNAs and brain inflammation.
Could Alzheimer’s disease and other types of cognitive decline be caused by the underproduction of immune cells that are poorly understood? It might, according to a Rutgers study published in Nature Immunology, and increasing these cells could undo the harm.
According to a recent study by researchers at the University of Colorado Anschutz Medical Campus, the overexpression of a gene linked to cell division and the structure and function of neurons could prevent and protect against cognitive deterioration in both mice and people with Alzheimer’s disease (AD).
AZoLifesciences speaks to Dr. Anneline Pinson and Prof. Dr. Wieland B. Huttner from The Max Planck Institute of Molecular Cell Biology and Genetics about their latest research which found a greater neuron production in the frontal lobe during brain development in modern humans than Neanderthals, due to the change of a single amino acid in the protein TKTL1.
A new paper published in Nature Communications adds further evidence to the bradykinin storm theory of COVID-19's viral pathogenesis -; a theory that was posited two years ago by a team of researchers at the Department of Energy's Oak Ridge National Laboratory.
Cognitive decline brought on by aging is a precursor to dementias like Alzheimer’s and can have a significant impact on a person’s ability to carry out essential daily tasks.
In a study published May 02, 2022 in Nature Communications, scientists at University of California San Diego School of Medicine used human brain organoids to reveal how a genetic mutation associated with a profound form of autism disrupts neural development.
The loss of functional neurons in the brain is a characteristic of Alzheimer’s disease. What, on the other hand, is the source of this loss?
LMU neuroscientists have shown that breathing coordinates neuronal activity throughout the brain during sleep and quiet.
In a breakthrough that holds significant promise for early diagnosis and better treatment of psychiatric illness, researchers have for the first time used neurons derived from human stem cells to predict the cardinal features of a psychiatric illness, such as psychosis and cognitive deficits in patients with schizophrenia.
A genetic predisposition for depression combined with exposure to high-particulate-matter air pollution greatly elevates the risk that healthy people will experience depression, according to a first-of-its-kind study published today in the Proceedings of the National Academies of Sciences from neuroscientists at the Lieber Institute for Brain Development, on the Johns Hopkins Medical Campus, and Peking University in Beijing, China.
Dementia is a condition that involves severe loss of cognitive function.
