In other research, Gaab and her colleagues have found an intriguing link between children's reading difficulties and neural deficits that prevent them from properly processing fast - changing sounds; they also found that computerized sound - training exercises «rewired» those faulty brain circuits.
In drug addiction — my field — rodents will self - administer and addict themselves to the same drugs that humans self - administer and addict themselves to, which makes it possible to identify the neural circuits in the brain, and the molecular changes within those circuits caused by drug exposure, that underlie states of addictioIn drug addiction — my field — rodents will self - administer and addict themselves to the same drugs that humans self - administer and addict themselves to, which makes it possible to identify the neural circuits in the brain, and the molecular changes within those circuits caused by drug exposure, that underlie states of addictioin the brain, and the molecular changes within those circuits caused by drug exposure, that underlie states of addiction.
This pruning changes the relative density of receptors in the circuit linking the area of the brain involved with processing rewards (the basal ganglia) and the area of the brain implicated in inhibition and control (the prefrontal cortex).
This kind of progressive speech impairment is associated with dysfunction in the cortical - basal ganglia brain circuit in both humans and songbirds, so Liu could make assumptions based on this trial about how the human brain circuit changes.
For decades, clinical and pre-clinical research considered that opiate consumption caused permanent changes in the brain's reward circuits, resulting in a persistent vulnerability to relapse.
For voles, the profound lifestyle change seems to have occurred when previously separate circuits in the male brain — one for processing social recognition, another for reward — became biochemically linked.
The critical role these changes play in brain development highlights the importance and urgency in understanding neural circuits in more detail and suggests new avenues for investigating the underlying causes of developmental disorders such as autism.

Laboratory studies have found that meditation produced changes in brain circuits involved in regulating emotion, Dr. Davidson said, and may reduce markers of inflammation and stress hormones like cortisol.
Emerging scientific investigation is improving our understanding of the causal biological pathways for these robust associations.46 Early childhood trauma, including physical abuse, leads to the production of stress hormones, such as cortisol and adrenaline that are normally protective, but with severe or persistent trauma can become toxic.47, 48 These stress hormones regulate neural circuits that are important in modulating an individual's response to stress, and over time, are associated with structural and functional changes in the brain and other organs.
