Summary

We plan to study patient who faint in response to the sight of blood and compare them to healthy subjects who do not. We are going to use a special type of MRI scan (functional MRI) to determine if there are differences in brain activation in response to seeing bloody or gory pictures that occur before the fainting occurs.

Detailed description

Another aim of the study is to determine whether or not differences in personality traits among people with blood phobia is associated with differences in BOLD signal responses during fMRI.

Conditions

• Syncope
• Blood Injury Phobia
• Autonomic Dysfunction

Interventions

Type	Name	Description
PROCEDURE	fMRI Scan	Subjects will undergo a functional MRI scan of the head lasting \~45 minutes. They will be repeatedly shown video clips of blood, other disgusting things, or are neutral.
