What characterises Electro-magnetic radiation 1. Wavelength 2. amplitude - height of wave from centreline to peak 3. Polarization - orientation vector of photons 4. frequency - number of wave cycles Why can people get sunburnt whilst sitting in the shade 1. Reflected UV radiation 2. Scattered UV radiation - from atmosphere and clouds What is a high pass filter? - Image enhancement technique which enhaces the edges and finer details of an image - This is done by subtracting a lo...

In a patient with epileposy, which region of focus (by lobe of the brain) is known to have the greatest incidence of NORMAL EEG? Frontal Lobe Seizures from here don't always show up on the EEG Catamenial Epilepsy - What is it? Includes women whose seizures are exacerbated by their menstrual cycle. Women with catamenial epilepsy are unusually sensitive to endogenous hormonal changes. This seizure exacerbation has a statistically significant positive correlation to serum estradiol/...
