Researchers Find Fear and Courage Switches in Brain - Neuroscience NewsHuman brains harbor a structure equivalent to the vMT, Huberman said. He speculated that in people with phobias, constant anxiety or PTSD, malfunctioning circuitry or traumatic episodes may prevent vMT signaling from dropping off with repeated exposure to a stress-inducing situation. In other experiments, his group is now exploring the efficacy of techniques, such as deep breathing and relaxation of visual fixation, in adjusting the arousal states of people suffering from these problems. The thinking is that reducing vMT signaling in such individuals, or altering the balance of signaling strength from their human equivalents of the xiphoid nucleus and nucleus reuniens may increase their flexibility in coping with stress.
Almost 15 minutes into the call, Tuff tried to defuse the situation by telling Hill about her own personal struggles. "Don't feel bad, baby. My husband just left me after 33 years...I got a son who's multiple disabled," she said. By the end of the call, when police can be heard storming the office, Tuff made it clear that, despite her apparent poise under the extreme pressure, she was frightened. "I'm going to tell you something, baby. I've never been so scared in all the days in my life," Tuff said before breaking down in tears. "You did great," the operator told her.
