Synesthesia and Non-Synesthesia Subjects

I am now looking for people with number-color synesthesia for spatial response time tests. You don't have to be located in the St. Louis area to take these tests.

I am also looking for non-synesthetes for an fMRI study that will be carried out at Washington University, St. Louis. The scan will take 2 hours and you will be asked to complete some rather trivial tasks (e.g. studying a photo) while inside the machine.

fMRI is a non-invasive procedure that measures changes in blood flow corresponding to activity in the brain. Radio waves redirect the axes of spinning protons in a strong magnetic field that is produced by passing an electric current through wire coils. A computer processes the signals and generates a series of images.

The procedure does not depend on ionizing radiation, there is no radiation exposure, and short-term exposure to magnetic fields and radio waves is considered harmless. fMRI scans therefore have no known side-effects and are not associated with any discomfort.

Only very few people should not get an fMRI. These include people who may be pregnant, people with whole-body tattoos and people with an internal defibrillator or pacemaker, an ear implant or clips on brain aneurysms. Platinum implants in other parts of the body do not compromise your safety during the procedure.

To qualify for this study, you must be located in the St. Louis area or be willing to travel to the St. Louis area. If you are interested, please email me at: brogaardb@umsl.edu

My Paper on Unconscious Perceptual Processes

The official link to my paper "Are there unconscious perceptual processes?" is now up. The paper manuscript is available in full on my homepage.

Drawing of a Migraine Aura

Alex Heim is a synesthete who also has migraine auras. He just sent me this drawing of one of his migraine auras.

Short Film on Synesthesia

One of the young synesthetic savants I work with in Australia just created this film on synesthesia.

New Synaesthesia Survey

I have uploaded a new synaesthesia survey to our synaesthesia page. The results of the survey will be used to improve the design of our synaesthesia studies at the University of Missouri, St. Louis.

If you are a synaestete, and you are interested in contributing to our ongoing synaesthesia studies, you can take our advanced synaesthesia survey by clicking below.

If you are interested in becoming a participant in our studies at the University of Missouri, St. Louis but you are not sure if you qualify, we have created a survey that will allow us to determine whether you do. The only required information is your email address. You do not have to be located in St. Louis to qualify.
