Nyquist Theory - The specification of the minimum sampling rate used, in relation to the highest frequency signal recorded The sample rate must be twice that of the highest frequency to be recorded. For LFF, the corresponding time constants for LFF cutout freq. of 3 hz would be - .05 seconds The most prominent clinical feature of Dilantin toxicity - Ataxia Ataxia - lack of muscle coordination Agnosia - the inability to recognize familiar objects. Apraxia - inability to perform particular ...

What environmental factors enhance lambda? a. low illumination visual scene b. noxious stimuli c. loud sounds d. scanning high complexity visual scene - scanning high complexity visual scene What is the electrical abnormality associated with breach rhythm? a. a focal high voltage electrical generator in the cortex b. a focal low impedance swelling of the scalp c. a focal high impedance pathway through the skull d. a focal low impedance pathway through the skull - a focal low impedance p...

What is the speed of light? - Light can travel enormous distances under short periods of time. It is faster than any other phenomenon. It takes about 8 minutes for light to travel from the Sun to Earth. The speed of light in a vacuum is c=3x10^8 m/s. Why is light such an important tool for astronomers? - Because light is how we learn about distant objects without travelling there. It is also a measuring took of astronomy. Light is a wave and a particle. How are different kinds of light wave...

EEG BOARD PREP PRACTICE QUESTIONS What stage of sleep will you find vertex waves? N1 What stage of sleep will you see sleep spindles? N2 What stage of sleep will you see POSTS? N1 What would an EEG look like of someone who has down syndrome? Normal If a patient is becoming "deeper" in a coma, triphasic waves are most likely to do what? Disappear What normal activity can be seen in C3/C4? Mu What is seen most often in children? Rolandic spikes What region do you see Rolandic sp...
