Currently, more than 6 million children in the United States, or 11% of all children aged 4 to 17, have received attention-deficit hyperactivity disorder (ADHD) diagnoses. The disorder is characterized … Continue Reading Neuroimaging shows interactions in attention-based brain networks weaker in children with ADHD.
Neuroplasticity, or brain plasticity, is an umbrella term that describes lasting change to the brain throughout life. One of the fundamental principles of how neuroplasticity functions is linked to the … Continue Reading Researchers identify previously unknown subtype of neuron in the visual cortex.
Approximately one out of a hundred people suffer from epilepsy and one out of twenty suffer a seizure at least once during their lifetime. Seizures occur when many nerve cells … Continue Reading Researchers identify a new neural mechanism in epilepsy.
Obesity is a significant risk factor for cardiovascular disease, diabetes, and cancer. Although obesity can stem from behavioural factors such as diet and physical inactivity, central nervous system changes can … Continue Reading Neuroimaging maps areas of the brain in obese children activated by food odours.
Human multitasking is the apparent performance by an individual of handling more than one task, or activity, at the same time. Studies have shown that some people can be trained … Continue Reading Neuroimaging study maps the neural basis of multitasking.
Morphine mediates its euphoric and analgesic effects by acting on the μ-opioid receptor (MOR). MOR belongs to the family of G-protein coupled receptors whose signaling efficiency is controlled by the … Continue Reading Researchers identify key morphine regulator in the brain.
Humans are unique among social creatures in their willingness to bear personal costs to punish those who have harmed others. Despite the centrality of such third-party punishment decisions to modern … Continue Reading Neuroimaging identifies uniquely human brain region responsible for judgment.
Many patients with high blood pressure develop coronary artery disease or heart failure, and many die as a result. However, as hypertension is a circulatory disease all parts of the … Continue Reading Researchers successfully detect early brain damage from hypertension in human study.
Antidepressants are recommended as a first-line treatment of severe depression and for the treatment of mild-to-moderate depression that persists after conservative measures such as cognitive therapy. Experts recommend against their … Continue Reading Study maps structural brain changes caused by antidepressants.
In their everyday life, people are constantly confronted with decision conflicts, especially if they need to suppress an action that would have made sense under normal circumstances. For example, when … Continue Reading Neuroimaging shows that the human hippocampus is involved in quick and successful decisions.
For several decades, addiction has come to be viewed as a disorder of the dopamine neurotransmitter system; however, this view has not led to new treatments. Numerous studies suggest that … Continue Reading Researchers identify specific neuron-type responsible for alcoholism.
The association between marijuana, also known as cannabis, and schizophrenia is historically fraught. In the 1960s and 1970s, scientists thought that smoking cannabis could trigger psychosis in anyone. Recent studies … Continue Reading Researchers identify link between cannabis use in young males and raised schizophrenia risk.
