In order to understand how the body's internal state affects the brain's decision-making process, scientists analyzed data from a previous preclinical study
Anxiety, addiction, and other mental illnesses are often characterized by intense states that scientists call awakening: rapid heartbeat, elevated blood pressure readings, shortened breathing, and making "bad" decisions
"Our research results indicate that the brain's decision-making circuits may be connected to continuously monitor and integrate what is happening in the body
The research was led by Dr.
For many years, scientists have described the relationship between awakening and decision-making performance as a "U-shaped curve
The preliminary results of this study support this view
Next, the researchers analyzed the electrical activity recorded by neurons in the two decision centers of the brain (called the orbitofrontal cortex and the dorsal cingulate cortex)
They found that the activity of about one-sixth of the neurons in these two areas was related to heart rate fluctuations
Brain scan studies have shown that body awakening changes the activities of these decision-making centers
To answer this question, the researchers analyzed data obtained after the amygdala, the emotional center of each animal's brain, was surgically closed
When the research team observed neural activity, they found something more interesting
