Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.
Electroencephalography is the technique used to acquire electrical signals of brain through electrodes which are placed by certain montage. Different wave patterns can be observed which is useful in detecting any abnormal conditions or neurological brain disorders in human beings. There is broad future scope for medical research and creating EEG based equipments for real time applications.

An electrogastrogram (EGG) is a graphic produced by an electrogastrograph, which records the electrical signals that travel through the stomach muscles and control the muscles' contractions. An electrogastroenterogram (or gastroenterogram) is a similar procedure, which writes down electric signals not only from the stomach, but also from intestines.
Late response are the most helpful findings in some of the diseases affecting the peripheral nerves, (e.g GBS, Radiculopathies, ). How to assess these responses while performing Nerve Conduction Studies, is the most technical and theoretical consideration.... Here we go with the same things in the stated slides
An electroencephalogram (EEG) is a test used to evaluate the electrical activity in the brain. Brain cells communicate with each other through electrical impulses. An EEG can be used to help detect potential problems associated with this activity.

EEG stands for Electroencephalography
It’s record the electrical activity of brain.
During an EEG test , small electrodes like cup or disc type are placed on the scalp.
They pick up the brain’s Eletrical signals and send them to a machine called Electroencephalogram.
Electroencephalograms (EEGs) are recordings of the minute (generally less that 300
μ
V) electrical
potentials produced by the brain. Since 1924, when Hans Berger reported the recording of rhythmic
electrical activity from the human scalp, analysis of EEG activity has been conducted primarily in clinical
settings to detect gross pathologies and epilepsies and in research facilities to quantify the central effects
of new pharmacologic agents.In 1875, Richard Caton published the first account documenting the recording of spontaneous brain
electrical activity from the cerebral cortex of an experimental animal. The amplitude of these electrical
oscillations was so low (i.e., in the microvolt range) that Caton’s discovery is all the more amazing because
it was made 50 years before suitable electronic amplifiers became available. In 1924, Hans Berger, of the
University of Jena in Austria, carried out the first human EEG recordings using metal strips pasted to
the scalps of his subjects as electrodes and a sensitive galvanometer as the recording instrument. Berger
was able to measure the irregular, relatively small electrical potentials (i.e., 50 to 100
μ
V) coming from
the brain.

Brain Control Interface using ELECTROENCEPHALOGRAPHY Squishey Bruns
Brain–computer interfaces (BCIs) enable users to control devices with electroencephalographic (EEG) activity from the scalp or with single-neuron activity from within the brain.
A brain–computer interface, commonly called a mind-machine interface, or called a direct neural interface or a brain–machine interface, is a direct communication pathway between the brain and an external device.
EEG’s are a noninvasive way to look into your brain. While the brain is extremely complex, areas of it can lock into circular firing patterns, resulting in telltale brain waves that one can observe with the right equipment. Intensity of these waves change depending on your internal state. The concentration of each wave can also tell more specific things about your thought patterns depending on where you measure them from.
The aim for this project is to be easily available and understood by people of every technology background.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. INTRODUCTION
• EEG stands for Electroencephalography.
• It is a device that analyze and records the electrical activity of
brain.
• During an EEG test , small electrodes like cup or disc type are
placed on the scalp.They pick up the brain’s Eletrical signals
and send them to a machine called Electroencephalogram.It
records the signals as wavy lines on to a computer screen or
paper in order of microvolt.
• EEG waves frequency range = 0.1 to 100 amplitude = 2 to 200
3. REQUIREMENTS:
EEG (8/16 channels),Silver cup electrodes/metallic bridge
electrodes,Electrode jelly,Rubber cap, dark comfortable room,Skin
pencil & measuring tape.
PROCEDURE:
• A standard non – invasive EEG takes about 1 hour. The patient will be
positioned on a padded bed or table , or in comfortable chair.
• To measure the electrical activity in various part of the brain , a nurse
or EEG technician will attach 16 to 20 electrodes to the scalp.
• The brain generates electrical impulses that these electrodes will pick
up. Then a temporary glue will be used to attach them to the skin , no
gain will be involved.
4. TYPES OF LOBES
•Frontal lobes: Emotional & motor control.
•Parietal lobes: Sensory purpose (pain , touch,
pressure).
•Temporal lobes: Auditory system (hear &
sound).
•Occipital lobes: Visual purpose (see & eye).
5. WHY EEG IS USED?
• Where there is a need to diagnose & manage epilepsy.
• Used to investigate other conditions such as head
injuries , brain tumours , dementia , hemorrhage.
• Determine the level of brain function in people who
are in a coma.
• Identify areas of the brain that are not working
properly.
6. ADVANTAGES:
• Non - invasive & harmless
• Lower costs
• Portable
• High temporal resolution
DISADVANTAGES:
• High noise ratio
• Not very exact measuring
• Skull weakness the electrical activity
• Low spatial resolution
7. APPLICATIONS
• Epilepsy
• Brain death testing • Various brain cancer Sleep disorders
(insomnia) , nacrolepsy , (uncontrollable sleep).
• Sleep paralysis (inability to move during full consiousness).
• Chronic hypersomnia (excessive sleep or sleepiness).
8. EMG
• Electromyography (EMG) is a technique for evaluating and
recording the electrical activity produced by skeletal muscles.
• EMG is performed using an instrument called
an electromyograph to produce a record called
an electromyogram. An electromyograph detects the electric
potential generated by muscle cells.
• when these cells are electrically or neurologically activated. The
signals can be analyzed to detect abnormalities, activation
level, or recruitment order, or to analyze the biomechanics of
human or animal movement.
9. • Needle EMG is an electrodiagnostic
medicine technique commonly used by neurologists.
• Surface EMG is a non-medical procedure used to
assess muscle activation by several professionals,
including physiotherapists, kinesiologists and
biomedical engineers.
• In Computer Science, EMG is also used as middleware
in gesture recognition towards allowing the input of
physical action to a computer as a form of human-
computer interaction.
10. USES OF ELECTROMYOGRAPHY
• Detect disorders of the motor units and can
indicate the site of the underlying lesion (anterior
horn cell,spinal root,plexus,peripheral nerve).
• Recognition of neuromuscular disorders.
• Provide a guide for prognosis.
11. ADVANTAGES OF EMG
• EMG auditory equipment is relatively inexpensive.
• Allows targeting of botulinum toxin within the muscle.
• Identify the presence of unwanted muscle activity during
passive and active movement.
• Identify muscle that is most spastic when dividing dosing.
