How the Brain’s Internal States Affect Decision-Making

Animals slowly shift their likelihood of detecting stimulus changes over ten minutes. Researchers found the activity of neural populations from the V4 visual area and prefrontal cortex slowly drifted together with the behavioral fluctuations. The slow drift acts as an impulsivity signal.

Developmental changes in the brain may influence how often adolescents get drunk

Teens with a particular pattern of brain development have an increased frequency of drunkenness, a new study reports. Decreased gray matter density in the frontal and temporal brain regions was associated with an increased risk of teenage over-drinking.

Brain scans may provide clues to suicide risk

Neuroimaging can be used to assess a person's risk of suicidal behavior. Those with mood disorders, a history of suicidal thoughts, and those with a history of suicide attempts have less connectivity in the cognitive control network. They also have reduced connectivity between the cognitive control network and the default mode network.

Impulsive behavior linked to sleep and screen time

Too little sleep and too much screen time are linked to increased impulsive behaviors, especially in younger people. Reducing recreational screen time to two hours a day and sleeping for 9-11 hours per night can help curb impulse behaviors.

Neuroscience research questions current alcohol limit

Drinking small amounts of alcohol, like one pint of beer or a large glass of wine, significantly impairs our feeling of being in control of our actions. A new study reveals even one beer can lead to overconfidence in driving ability and make us act in inappropriate, potentially dangerous ways. The study begs the question, are current alcohol limits for driving truly safe?

Creativity: A question of impulsiveness

The effects of schedule autonomy on creative performance are dependent upon a person's level of impulsivity. The more impulsive a person is, the more creative they are. The reverse is true for those who are more controlled.

Different Brain Areas Linked to Smoking and Drinking Behaviors

A new study reveals researchers have identified areas of the brain which are different in those who regularly smoke and drink alcohol. Researchers discovered the medial orbitofrontal cortex, an area of the brain implicated in reward, has higher functional connectivity in drinkers. In those who smoke, the lateral orbiotfrontal cortex, an area of the brain linked to impulsive behavior, has lower functional connectivity. The study suggests nicotine may increase overall brain connectivity, which may lead to increased smoking behaviors.
