Abnormal 12-Hour Cyclic Gene Activity Found in Schizophrenic Brains

Postmortem brains of those with schizophrenia have fewer genes associated with 12-hour activity cycles in the dorsolateral prefrontal cortex. Mitochondrial-related genes in the dlPFC did maintain a 12-hour rhythm, but their activity did not peak at normal times.

Brain Patterns Reveal Why Elderly Drivers Are Prone to Mistaking the Gas Pedal for the Brake Pedal

Older people have longer reaction times, slower decision times, and greater activation in brain areas involved in inhibition and task switching. The findings may shed light on why many older drivers mistake the accelerator for the brake pedal.

Brain Gene Expression Patterns Altered by Chronic Opioid Use

Opioid use disorder affects genes associated with proinflammatory immune molecule encoding and genes associated with remodeling the extracellular matrix, suggesting the connection between neurons may be altered as a result of opioid use. Additionally, those with OUD have higher levels of microglia in the brain.

Non-Invasive Brain Stimulation May Reduce Smoking

Non-invasive brain stimulation, such as rTMS, helps to reduce smoking frequency in nicotine-dependent people, a new study reports. Stimulating the dorsolateral prefrontal cortex with repetitive transcranial magnetic stimulation significantly reduced smoking frequency.

How the Brain Helps Us Navigate Social Differences

When we talk to someone from a different socioeconomic background our brain reacts differently than when we address someone with a similar status to our own. Researchers found higher activity in the dorsolateral prefrontal cortex, an area of the brain associated with language and attentional control when people speak with those of different socioeconomic status.
