Dogs with anxiety have stronger neural connections between the amygdala and other areas of the anxiety network in the brain compared to less anxious dogs.
If neural assemblies between the hippocampus and prefrontal cortex fail to sync together at the correct time, memories are lost.
Researchers have developed a more powerful and energy-efficient memristor, based on the structure of the human brain, that combines data storage and processing. The new technology, made from nanocrystals of halogenated perovskite, is not yet ready for use as it is difficult to integrate with existing computer chips, but it has potential for parallel processing of large amounts of data.
Older adults who consumed a Mediterranean-style diet had a 23% lower risk of developing dementia than those who consumed a typical diet.
Navigational problems and an increased risk of developing prosopagnosia, or face blindness, have been associated with COVID-19 infection.
Higher levels of immune proteins are present in the blood both before and after an epileptic seizure. Researchers say the biomarkers can be identified via a simple blood test.
A new study suggests that experiencing aesthetic chills, or goosebumps, during stimuli like music, films, and speeches can lead to increased emotional intensity and positive valence. The study's findings may have implications for understanding the role of embodied experiences in perception and decision-making and for the treatment of dopamine-related disorders such as Parkinson's, schizophrenia, and depression.
Targeting and reducing the methylation of a key mRNA promoted the migration of macrophages in the brain and can improve cognitive symptoms of Alzheimer's disease.
As the brain ages, microglia adopt dysfunctional states that increase the risk of developing neurodegenerative diseases such as Alzheimer's disease.
A newly developed blood test screens for biomarkers associated with anxiety to determine a person's risk of developing the disorder as well as monitor the severity of symptoms in those with anxiety.
Historically in neuroscience research, male mice have been favored over female mice in experiments due to the belief that the female hormone cycle can cause behavioral variations that may skew results. Researchers now argue that despite hormone cycles, female mice show more stable exploratory behaviors than males. The findings make a strong case for increasing the inclusion of female mice in neuroscience research.
The more a person is able to synchronize to a simple beat, the better they are at synchronizing their pupils with those of another person.
