Because substances of abuse act directly on the reward center of the brain to deliver their high—this involves speedy and intense release of the neurotransmitter dopamine—addiction can be seen as a shortcut to reward, one that, over time, can have a high cost to physical and mental health....
“Past studies in the field of addiction research have focused on the medial prefrontal cortex, which is the part of the brain that controls decision making, but no effective prevention or treatment for drug relapse is available,” said Yao-Ying Ma, MD, Ph.D., assoc...
Which part of the brain controls nicotine addiction? | Freedom From SmokingJonathan Foulds
"Understanding what part of the brain is involved in causing intense narrowing of focus to make one reward valued at the detriment of all others might provide crucial insights into treating addiction and excessive/compulsive consumption disorders," Robinson said. In the study, whenever the rats push...
New research reveals that brain damage affecting the insula – an area with a key role in emotions – disrupts errors of thinking linked to gambling addiction. The research, led by Dr Luke Clark from the University of Cambridge, was published today, 07 A
The receptor they targeted, the GPR139, is located primarily in a part of the brain called the habenula, which is activated during drug and alcohol withdrawal. "We're been very interested in the habenula because this is the area of the brain that prod...
We review drug addiction from the perspective of the hypothesis that drugs of abuse interact with distinct brain memory systems. We focus on emotional and procedural forms of memory, encompassing Pavlovian and instrumental conditioning, both for action–outcome and for stimulus–response associations. Ne...
Rezai's team focused ultrasound into a part of the brain called the thalamus to destroy a pin-point sized patch of tissue doctors believed was responsible for the tremors. Dr. Ali Rezai: These are the 980 elements converging right there. ...
In recent years, the conceptualization of addiction as a brain disease has come under increasing criticism. When first put forward, the brain disease view was mainly an attempt to articulate an effective response to prevailing nonscientific, moralizing, and stigmatizing attitudes to addiction. Accord...
The ACC has been coined the most interesting part of the brain56because of its many proposed functions., These include salience attribution57, Bayesian prediction error processing58, representation of the requirements needed for maintaining homeostatic balance59and driving appropriate behavioural responses60...
