  SPECT Brain Scan   (Site not responding. Last check: 2007-10-20)
Mohammed Moinuddin was invited to give a talk in the Department of Family Practice in February 21, 1994 on the clinical utility of SPECT brain scan.
HMPAO (hexamethyl propylene anime oxime), commercially known as Ceretec is a lipophilic compound that localizes in the brain proportional to the blood flow.
Hence, areas of decreased and increased blood flow are seen on the scan as "cold" or "hot" areas.

 Reading the Brain
With the impact the affected brain cells send a biochemical signal to the cells in the corresponding organ causing either the growth of a tumor, a meltdown of tissue or functional loss, depending on which brain layer received the conflict shock.
While the brain stem (the oldest part of the brain) is programmed with basic survival issues like breathing, reproduction and food, the cerebrum (the youngest part of the brain) is concerned with more advanced themes such as territorial conflicts, separation conflicts or self-devaluation conflicts.
A brain scan together with a thorough medical history is vital to establish the duration of the healing phase as well as complications that can be expected.

 Brain scans for sale. - By David Dobbs - Slate Magazine
At first this technology served primarily to refine a basic map of the brain's main functional areas—showing, for instance, that certain regions in either hemisphere process and generate language or that the amygdala, an almond-sized area near the brain's center, acts as a sort of hub connecting sensory perception, emotion, and memory.
Scan studies have tracked the maturation of decision-making regions during adolescence; clarified how we store, retrieve, and lose memories; and identified the neural correlates of fear, distraction, and affection, as well as of various character traits, including extraversion, empathy, and persistence.
This means that the only way that a brain scan can yield an accurate pattern that is unique to a particular stimulus/activity/task is to track the temporal changes of activity in all regions of cortex (and not simply the particular "brain centers" associated with the activity through neurological lesion studies).

 Brain scan may help stop schizophrenia - smh.com.au
It is already accepted that the structure of the brain is different in people with schizophrenia but the new research is the first to show those changes coincide with first symptoms.
Dr Pantelis used magnetic resonance imaging to scan the brains of 75 people deemed to be at exceptionally high risk of psychotic illness - as they had some symptoms of mental disturbance and had a family history of the condition - when they first attended the university's Personal Assessment and Crisis Evaluation Clinic.

 RedOrbit - Science - New Love Behavior Spotted in Brain Scan   (Site not responding. Last check: 2007-10-20)
As a relationship deepens, the brain scans suggest, the neural activity associated with romantic love alters slightly, and in some cases primes areas deep in the primitive brain that are involved in long-term attachment.
This passion-related region was on the opposite side of the brain from another area that registers physical attractiveness, the researchers found, and appeared to be involved in longing, desire and the unexplainable tug that people feel toward one person, among many attractive alternative partners.
The brain images, also taken while participants looked at photos of their beloved, showed activation in many of the same areas found in the new study -- but significantly less so, in the region correlated with passionate love, she said.

 DrSPECTscan.com - How is brain SPECT scanning done?
Because the scan is about how the brain has blood flow and function, anything such as reaction to a needle stick could have an effect on the resulting scan.
When returning for the scan, the person lies on the scan table with his or her head placed in a head-holding device.
The scanning camera has two or three large imaging lenses that rotate completely around the person's head, resulting in a three-dimensional volume of data that includes all the blood flow and function information inside of the person's head.

 Early McLean tests show brain scan eases depression - The Boston Globe
McLean Hospital researchers have stumbled upon a possible new treatment for depression, finding that performing a novel type of brain scan on bipolar patients can quickly and significantly lift a patient's mood, apparently because the scanner's unusual magnetic fields affect the electrical workings of their brains.
The study, published in the Jan. 1 issue of the American Journal of Psychiatry, examined 30 bipolar, or manic-depressive, patients whose brains were scanned using Echo-Planar Magnetic Resonance Spectroscopic Imaging, a method that can analyze the chemistry in small sections of the brain.
Of the 11 patients who were not on medications, all 11 reported that scanning improved their mood.

 Mind Hacks: New brain scan detects 'instant' biological changes
Brain Ethics have picked up on a new development in fMRI brain scanning technology that has the potential to detect fast changes in brain activity.
Research just published by neuroscientist Denis Le Bihan and his team has found that changes in brain activation can be detected by measuring water diffusion through neurons.
This type of water diffusion is thought to reflect the activity of the cells, but crucially, it seems it provides a more direct and quicker measure of brain activity than conventional methods.
