Ventromedial prefrontal cortex

Vera is an eight-year-old African American female who lives with her mother and has visitation with her father every other weekend. She was brought to the clinic by her mother in response to concerns reported by her teacher at school, as well as difficulties at home, concerning odd and disruptive behaviors, obsession concerning her mother’s safety, anxiety, and declining academic performance. Diagnosis Based on her presenting symptoms, Vera meets the full criteria for Obsessive Compulsive…

I. It was an ordinary relaxing day at Coney Island Hospital and I was the only volunteer (usually 3) that Saturday in the hospice unit. I remember this event clear as day. All the 6 nurses on our unit ran to one room and I felt this feeling of panic spread throughout the floor. I had to stay calm and try my best to mind my own business. All I heard was a nurse and doctor yelling does anyone know how to speak Russian? My heart fell to my toes and I automatically ran to the room, they dressed me…

are still being made in this realm of disorders. In the coming years, it is to be expected that more genetic related studies will help us understand the nature versus nurture link. We may also see more gene regulating developmental process in prefrontal cortex as well as in other brain areas (Xiao et al., 2014). Animal models will also be crucial in this research so that we can easily see the development of certain types of mutations and how they present (Xiao et al.,…

brains of those with PTSD compared with those without PTSD. The areas of the brain that are known to be affected and responsible for bringing on the usual symptoms of posttraumatic stress disorder are the hippocampus, amygdala, and the ventromedial prefrontal cortex. (Wlassoff 2015) The damage causes these areas, collectively, to change the mechanisms of stress responses that impair perception and responses in patients with PTSD compared to someone who has not been traumatized. (Wlassoff 2015)…

In the present study, we anticipated that brain regions in prefrontal cortex may be the neural basis of the relation between TP and delay discounting. Individual differences in diverse cognitive functions can be reliably inferred from neuroanatomical structure (Gaser and Schlaug, 2003; Gilaie-Dotan et al., 2013; Gilaiedotan…

exhibiting expressions of pain, participants in the control group experienced more activity in the periaqueductal gray, the right ventromedial prefrontal cortex and the right lateral orbitofrontal cortex, which plays a significant role in processing emotion and empathy. The high psychopathy group experienced more activity in the dorsal striatum, the dorsomedial prefrontal cortex, and the posterior superior temporal sulcus…

do so, research that shows the effect of deficits in the ventromedial prefrontal cortex on decision making will be presented, which allow for the presentation of research shows that there is a connection between deficits in this brain region and psychopathic traits in individuals. Therefore, the tendency towards the utilitarian decision-making model will be shown to be mediated by demonstrated differences in areas of the prefrontal cortex held by psychopathic individuals that provide for greater…

hypothalamus has also been found to cause thirst. Furthermore, Sakurai (1998) said that the lateral hypothalamus undoubtedly plays an important role but it’s not the eating centre as recent research has shown that neural circuits control eating. The ventromedial hypothalamus is the opposite of the lateral hypothalamus in that it signals to stop eating. Researchers concluded this as stimulation of the area reduces feeding and if it is removed in rats they over eat. Yet, Gold (1973) found that…

The review article by James M. Taylor & Paul J. Whalen (2015) discusses the neural regions and networks frequently associated in anxiety disorders. Specifically, the authors discuss the role of the amygdala, prefrontal cortex (PFC) and insula in anxiety disorders. One of the more reliable findings across studies of the anxiety disorders is amygdala hyperresponsivity. To illustrate, a study done by Hariri and colleagues discovered that amygdala reactivity to environmental threat is controlled by…

1992, a patient developed antisocial disorder after a surgery for removing a pituitary tumor. This harmed the orbitofrontal cortex (a component of the frontal lobe); however, neither neuropsychological nor personality tests showed particular mental default. Anna and Antonio Damasio, Portuguese neurologists, have announced in 1990 that people with damaged ventromedial frontal cortex showed unusual behavior, which caused some…
