Using an EEG Amplifier as a Pathway to Understanding Epilepsy
Epilepsy, a disorder of the central nervous system, is a frustratingly difficult condition, both for the person afflicted with it, and the doctors who study it. Essentially defining who we are, the human nervous system is a communications network that controls every thought, emotion, memory, and movement. Epilepsy causes the brain's electrical rhythms to become imbalanced, resulting in reoccurring seizures. Scientists have developed a miniaturized EEG amplifier (monitoring system) to help study epilepsy.
The brain communicates with nerves traveling throughout the body, which function like telephone lines, enabling the brain to communicate with every part of the body using electrical signals. In an effort to lower nursing care, scientists have found the use of an EEG Amplifier effective. Intracranial electroencephalogram (EEG) monitoring involves recording multi-contact electrodes. Doctors are able to use an EEG amplifier to integrate into electrode connectors. Electrode connectors are placed strategically on the scalp since different areas of the brain control different functions. This EEG amplifier records electrical signals from the brain and can be mounted on the head for patient comfort and convenience.
The EEG amplifier records the brain's electrical activity as a series of wavy lines called traces. Each trace corresponds to a different region of the brain. If seizures arise from a specific area of the brain, then the initial symptoms of the seizure often reflect the functions of that region. This type of information is extremely useful to doctors caring for epilepsy patients. Monitoring patients can become uncomfortable for them if they are to remain in a hospital for extended lengths of time. Portable and convenient, the miniature EEG amplifier can be worn on the patient in the comfort of their own home while multiple channels of useful data are being recorded for later study. It's this kind of state-of-the-art technology that will lead to a greater understanding of epilepsy.

Waves are the effect of energy on matter. Which of the following is a property of matter, but not of a wave?
A. amplitude
B. wavelength
C. mass
D. pitch
Which of the following is one possible way to direct an interfered wave at a particular angle?
A. prism
B. mirrors
C. phased array
D. amplifiers
When tracing pendulum motion on a moving paper recording, the width of the pendulum swing will determine the wavelength of the trace.
True or False
When two waves coincide in space and in time, they _______ each other.
A. diffract
B. interfere with
C. collide with
D. bounce off of
When two waves interfere, the result can be either constructive or destructive.
True or False
mass
prism or mirror i think
umm as i remember the period of a pendulum is determined by its radius. this question is ambiguous because a large width could indicate a larger radius or it starts swining from a greater height. Im not sure what the right answer here is.
interfere
true
