A new study from researchers at UCLA indicates that new memories with emotional content can be formed even if the amygdala is damaged. Researchers believe that other areas compensated for the damaged amygdala, and aided learning and memory.
A new study published in Frontiers in Aging Neuroscience has proven that moderate exercise can help to enhance connectivity in brain circuits. Additionally, exercise can help to improve cognition and combat decline in brain functions associated with aging.
Researchers at Carnegie Mellon have examined the function of neuron diversity and discovered that diversity is vital to comprehensive brain function. The study explored how specific neurons process complex stimuli and code information.
Neuroscience researchers suggest that utilizing fMRI studies could help to provide biomarkers for the diagnosis of depression. A recent fMRI study of patients with depression showed marked abnormal activations in the medial prefronal cortex. Researchers believe that by identifying the neurobiological markers for depression, psychiatrists can tailor medications and therapies to suit the needs of individual patients.
Scientists have identified two proteins which may have a critical function in biological systems. The proteins, named Piezo1 and Piezo2, have been identified as being involved in cellular response to mechanical stimulation.
New research proposes that academic performance of adolescents is linked to specific dopamine gene variations. Researchers also suggest a correlation exists between the variants of dopaminergic genes a student possesses and performance in specific subject areas.
Neuroscience researchers have discovered how a structural component within neurons performs coordinated movements when connections are strengthened. Researchers also distinguished two separate steps during long term potentiation which are involved in remodeling the internal "skeletons" of dendritic spines. The research could be influential in providing further understanding of many neurological, cognitive and neurodegenerative diseases.
New psychology research from CU-Boulder suggests that "neural inhibition" is a critical component in our ability to make choices. Psychologists have proposed people who suffer from anxiety could have decreased neuronal inhibition, which makes it more difficult to make important decisions.
Researchers have discovered that children exposed to high levels of manganese in drinking water perform poorly on cognitive tests. The research stated that, on average, children who drink water with more concentrated levels of manganese have an IQ score 6 points lower than children whose drinking water contained little to no manganese.
Neuroscientists have identified an area within the brain which controls impulsive behavior and have discovered the mechanisms that affect how impulsive behavior is learned. Training rats to control impulsive responses, neuroscientists discovered electrical signals between cells in the frontal lobe grew stronger when impulses were controlled. These findings could eventually help to help diagnose and treat impulse behavior problems such as addiction, obsessive compulsive disorder and ADHD.
