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.
The anterior cingulate cortex generates a reactive alarm, increasing its activity to signal to the dorsolateral prefrontal cortex to stop intrusive thoughts and memories.
The stress hormone cortisol reduces altruistic behaviors and alters brain activity in the dorsolateral prefrontal cortex in people with higher levels of empathy.
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.
The stronger the connection between the dorsolateral prefrontal cortex and temporal-parietal junction, the less likely people are to punish others for selfish deeds.
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.
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.
Repetitive transcranial memory stimulation applied to the dorsolateral prefrontal cortex modifies the negative effects of fear memories. The findings could have implications for the treatment of PTSD.
Researchers have identified a hippocampal neural network that activates during stress. Activity in a hippocampal-hypothalamus network predicts greater feelings of stress, while connectivity between the hippocampus and dorsolateral prefrontal cortex predicts less stress.
