A recent study led by Evan Forman, PhD, a psychology professor in Drexel University's College of Arts and Sciences, shows that a computer game can be used to train its players to eat less sugar, as way of reducing their weight and improving their health.
Researchers at the Institute of Neuroscience of the Chinese Academy of Sciences provided new insights into the functional role of the PPC in decision-making. They obtained compelling evidence to show that the posterior parietal cortex (PPC) indeed plays an essential role in decision-making under critical conditions that were largely ignored in previous studies.
MIT neuroscientists have found that using flickering light to stimulate gamma oscillations in the brain has widespread effects on neurons and immune cells called microglia. This treatment reduces inflammation, enhances synaptic function, and protects against cell death in mice that are genetically programmed to develop Alzheimer's disease.
Electroconvulsive therapy (ECT) helps people with severe depression by 'pushing the reset button' on brain networks involved in creating a mental picture, according to recent Baycrest findings.
Brown University researchers have discovered that instances in which outcomes are better than expected -- finding an unexpectedly good parking spot, for example, or spotting a $20 bill on the sidewalk -- improves memories of specific events. This is in addition to the long-established role that unexpectedly good outcomes have in influencing what are called integrated memories.
A newly identified epigenetic hotspot for schizophrenia and bipolar disorder may give scientists a fresh path forward for devising more effective treatments and biomarker-based screening strategies. More than 100 million people worldwide have either schizophrenia or bipolar disorder, which are characterized by periods of hallucinations, delusions and irregular thought processes. They are both associated with overproduction of the neurotransmitter dopamine, a key regulator of reward-seeking behavior, emotional responses, learning and movement, among other functions.
This is a peer-reviewed observational study conducted in humans. Researchers have shown that a functional magnetic resonance imaging (fMRI) 'lie detector' test, which measures brain activity, can be 'deceived' by people using mental countermeasures. The study suggests that more should be done to detect mental countermeasures before using fMRI tests for forensic applications.
Male and female rats whose mother experienced a simulated viral infection during pregnancy behave abnormally, consistent with behavioral alterations in autism or schizophrenia.
Caring for family members with dementia -- which is on the rise in the US -- causes significant emotional and physical stress that increases caregivers' risk of depression, anxiety and death. A new method of coping with that stress by teaching people how to focus on positive emotions reduced their anxiety and depression after six weeks, reports a new national study. It also resulted in better self-reported physical health and positive attitudes toward caregiving.
How sensory perception in the brain affects learning and memory processes is far from fully understood. Two neuroscientists of Ruhr-Universität Bochum have discovered a new aspect of how the processing of odours impacts memory centres. They showed that the piriform cortex -- a part of the olfactory brain -- has a direct influence on information storage in our most important memory structure, the hippocampus.
