I read this headline and said, “Wow!, finally I won’t need to CT all those patients’ heads!”
FDA permits marketing of the first hand-held device to aid in the detection of bleeding in the skull
Helps to determine if immediate CT scan is needed
The U.S. Food and Drug Administration today allowed marketing of the first hand-held device intended to aid in the detection of life-threatening bleeding in the skull called intracranial hematomas, using near-infrared spectroscopy.

But then, wait, said I, is it any good? Read more »

Human brains have a consistent molecular architecture despite all the other genetic differences across individuals and ethnicities, according to two studies that recorded when and where genes turn on and off in multiple brain regions throughout life.
Despite individual and ethnic genetic diversity, the human prefrontal cortex shows a consistent molecular architecture, as shown in this picture. The vertical span of color-coded areas is about the same, indicating that our brains all share the same tissue at a molecular level, despite distinct DNA differences on the horizontal axis. Each dot represents a comparison between two individuals.
The research appeared in the Journal Nature and was described by the National Institutes of Health in a press release.
The first study focused on Read more »

Cerebral vasculitis is a known cause of ischemic and hemorrhagic strokes and has been described as one of the rare but important causes of corpus callosum infarction. Biopsy-proved giant cell arteritis causing callosal infarction is an exceedingly rare finding because a tissue specimen is usually not obtained and conclusions are drawn on the basis of clinical and radiologic findings alone. We present a case of callosal infarction, which evolved and eventually affected large portions of both cerebral hemispheres.
A 63-year-old woman presented to our hospital with left-sided numbness and neglect, cognitive changes, and apraxia. One month earlier, she was found to have a C-reactive protein level of 8.0 mg/dL (normal <0.5 mg/dL) and 75% stenosis in both femoral arteries. These results prompted Read more »

This is one of the best pictures I’ve ever seen. I’m almost totally a left brain… What about you?
Left brain: I am the left brain. I am a scientist. A mathematician. I love the familiar. I categorize. I am accurate. Linear. Analytical. Strategic. I am practical. Always in control. A master of words and language. Realistic. I calculate equations and play with numbers. I am order. I am logic. I know exactly who I am.
Right brain: I am the right brain. I am creativity. A free spirit. I am passion. Yearning. Sensuality. I am the sound of roaring laughter. I am taste. The feeling of sand beneath bare feat. I am movement. Vivid colors. I am the urge to paint on an empty canvas. I am boundless imagination. Art. Poetry. I sense. I feel. I am everything I wanted to be.

Researchers at Johns Hopkins published a study that reports that MRI scans CAN cause feelings of dizziness induced by magnetic fields causing motion of the electrically charged fluid of the inner ear.
In both ears, there is a “gyroscope” called the labyrinth. Whenever the head turns or a force like gravity is exerted on this system, fluid moves within, which tells the brain that motion has occurred. It’s much like looking into a glass of water and based on the way the water tilts in the glass, you can guess which way motion is occurring.
In any case, the study Read more »
