The measurement of electrical activity in different parts of the brain and its recording as a visual trace on paper or oscilloscope is called electroencephalography or EEG and the device used in this procedure is termed electroencephalograph, operating by tracking and recording electrical activity of the brain, in the form of various brain wave patterns, which change according to different brain stages, mental activities, abnormalities of brain structures as well as surroundings.

A Typical EEG

Short history of electroencephalography

  • 1842–1926- Richard Caton is regarded as the first scientist to investigate brain potentials
  • 1854–1919- Napoleon Cybulski presented the electroencephalogram in a graphical form by applying a galvanometer with a photographic attachment and was the first to observe epileptic EEG
  • 1863–1939- Adolf Beck was the first to discover (in 1890) the rhythmical oscillations of brain electrical activity and alfa blocking during photic stimulation of eyes
  • 1929- Hans Berger recorded the first electroencephalogram from the surface of the human scalp
  • 1935- The first electroencephalograph (Grass Model-I), continued as contemporary EEG recording
  • 1935- F. Gibbs and H. Davis showed association of 3/sec spike-wave complexes in EEG with epileptic absences
  • 1935- A. L. Loomis et al. studied human sleep patterns

Origin of wave patterns by brain activities

There is a chain of electrical instances in the form of neuroelectrophysiological activity, occurring during various brain activities, both normal and abnormal. During electrical changes in neuronal system, electromagnetic flux is altered accordingly. This flux appears in the form of various brain activity wave forms and can be studied with several devices like EEG (Electroencephalography), MRI (Magnetic resonance imaging), SPECT (Single photon emission tomography), PET (Positron emission tomography) etc. which record physiological as well as organic activities of living tissues.

Types of wave forms

The major wave forms appearing during brain functioning are-

Gamma waves

These are involved in higher processing tasks as well as cognitive functioning and are important for learning, memory and information processing. The 40 Hz gamma wave is important for the binding of senses in perception and is involved in learning new material. Mentally challenged and persons with learning disabilities have lower gamma activity.

  • Frequency range: 40 Hz to 100 Hz (Highest)
  • Increased: Anxiety, high arousal, stress
  • Decreased: ADHD, depression, learning disabilities
  • Optimal: Binding senses, cognition, information processing, learning, perception, REM sleep
  • Aggravation: Meditation

Beta waves

These are high frequency low amplitude brain waves and commonly present during wakefulness. Beta waves are connected with physical world, physical senses and actions. These are involved in conscious thought, logical thinking, and tend to have a stimulating affect. Optimum amount of beta waves allows one to focus work-based tasks easily. Having too much beta may lead to experience excessive stress and/or anxiety. The higher beta frequencies are associated with high levels of arousal. Beta waves are generated during critical thinking, writing, reading, and socialization.

  • Frequency range: 16 Hz to 30 Hz (High frequency, low amplitude)
  • Origin: Parietal and frontal regions, bilaterally symmetrical
  • Increased: Adrenaline, anxiety, high arousal, inability to relax, stress
  • Decreased: ADHD, daydreaming, depression, poor cognition
  • Optimal: Conscious focus, memory, problem solving
  • Aggravation: Coffee, energy drinks, various stimulants

Alpha waves

Alpha waves bridge the slit between conscious thinking and subconscious mind as the alpha is the frequency range between beta and theta. These waves are connected with dynamic mind, vision and imaginations. These calms down when necessary and promote feelings of deep relaxation. During stress, “alpha blocking” may occur which involves excessive beta activity and very little alpha. Basically, the beta waves inhibit the production of alpha as the individual is too aroused.

  • Frequency range: 9 Hz to 15 Hz (Moderate)
  • Origin: Occipital region, bilateral, central during rest
  • Increased: Daydreaming, inability to focus, too relaxed
  • Decreased: Anxiety, high stress, insomnia, OCD
  • Optimal: Relaxation
  • Aggravation: Alcohol, marijuana, relaxants, some antidepressants

Theta waves

Theta waves are involved in feeling deep, raw emotions daydreaming and sleep. These are connected with insight, biological intelligence, disappointment and frustration as well as degenerative brain diseases. Too much theta activity may produce spells of depression or a pseudo state of semi hypnotism, as being deeply relaxed. These waves improve intuition, creativity, and make feel more natural. They are also involved in restorative sleep.

  • Frequency range: 5 Hz to 8 Hz (Slow frequency and high amplitude)
  • Origin: Parietal and temporal
  • Increased: ADHD, depression, hyperactivity, impulsivity, inattentiveness
  • Decreased: Anxiety, poor emotional awareness, stress
  • Optimal: Creativity, emotional connection, intuition, relaxation
  • Aggravation: Depressants

Delta waves

These are the slowest waves and found most often in infants and young children and decrease with age even in deep sleep. They are associated with the deepest levels of relaxation and restorative healing sleep and involuntary body functions such as regulating heart beat and digestion. Enough delta waves make feel completely rejuvenated after waking up from a good sleep. Any abnormal delta activity shows learning disabilities or difficulties maintaining conscious awareness as in cases of brain injuries.

  • Frequency range: .1 Hz to 4 Hz (Slowest frequency and highest amplitude)
  • Origin: Frontal in adults and occipital in children
  • Increased: Brain injuries, learning problems, inability to think, severe ADHD
  • Decreased: Inability to rejuvenate body, inability to revitalize the brain, poor sleep
  • Optimal: Immune system, natural healing, restorative / deep sleep
  • Aggravation: Depressants, sleep

Different EEG Waves

Electroencephalography procedure

This is a simple procedure of placing electrodes on scalp in a sequential manner and recording by EEG machine and interpretation of the graph produced. During an EEG procedure, following factors are considered-

  • Frequency
  • Voltage
  • Location
  • Morphology
  • Polarity
  • State
  • Reactivity
  • Symmetry
  • Artifact

EEG recording is based on following points-

  • Measurement of spatial distribution of voltage fields and variation over time
  • Sum of excitatory and inhibitory postsynaptic potentials from apical dendrites of pyramidal cells in outer layer of cerebral cortex
  • These readings are modified by input from subcortical structures, e.g. thalamus, ascending reticular activating system
  • The dendritic generators have two poles (dipole: + and -) and are oriented vertically
  • Scalp electrode signal detection requires synchronous discharge in approximately 10cm2 of cortex
  • Differential amplifier records potential difference between two scalp electrodes
  • Upward deflection when input 1 is relatively negative compared to input 2

Electrode placement

The 10/20 system is an internationally recognized method to describe the location of scalp electrodes. This system is based on the relationship between the location of an electrode and the underlying area of cerebral cortex. The numbers ‘10’ and ‘20’ refer to the fact that the distances between adjacent electrodes are either 10% or 20% of the total front-back or right-left distance of the skull. Each site has a letter to identify the lobe and a number to identify the hemisphere location.












No central lobe exists, the ‘C’ letter is used for identification purposes only






The ‘z’ (zero) refers to an electrode placed on the mid line


Four anatomical landmarks are used for the essential positioning of the electrodes-

  • The nasion which is the point between the forehead and the nose
  • The inion which is the lowest point of the skull from the back of the head and is normally indicated by a prominent bump
  • The pre-auricular points anterior to the ear on either side

Various electrodes are applied on scalp keeping following points into consideration-

  • Scalp electrodes applied according to the International 10-20 System
  • Even numbers (2,4,6,8) refer to electrode positions on the right hemisphere
  • Odd numbers (1,3,5,7) refer to electrode positions on the left hemisphere
  • Extra positions are added by utilizing the spaces in between the existing 10/20 system
  • Fp (frontopolar), F (frontal), C (central), P (parietal), O (occipital) and T (temporal), odd numbers (left), even (right), A (ear)
  • The collection of derivations for multiple channels recorded simultaneously and arranged in a specific order is called Montage

Another system places the EEG electrodes on scalp at 10 percent distances and is termed as 10/10 system.

Homoeopathy and EEG

Brain is a very complex structure, both anatomically and physiologically. The cerebral cortex is considered the seat of complex thought. Visual processing takes place in the occipital lobe. The temporal lobe processes sound and language, and includes the hippocampus and amygdala, which play roles in memory and emotion, respectively. Parietal lobe integrates input from different senses and is important for spatial orientation and navigation.

All these functions are integrated with each other in a synchronized way. Miasmatic changes tremendously alter normal state of health and produce severe physiological as well as pathological changes. Their slightest disharmony leads to the worst forms of disorders. During each function, there is a chain of highly regulated electrophysiological reactions inside neurons of the brain. Their existence is recorded by EEG in the form of various waveforms developed during potential changes in different brain areas. Any abnormal change in these functions disturbs the appearance of normal waves and seen in recorded electroencephalogram. The slightest stimulation and even minor emotional changes or thoughts can alter these waveforms.

Thus, we can interpret the mental state as well as organic lesions of an individual at a particular time of recording an EEG. In this way, EEG becomes a very important and infallible tool in diagnosing problems in higher functions of an individual, which are most important in evaluation of a case. These waveform changes in EEG may be a tool to successful selection of a similimum remedy for that case.

Here is a summary of the waveform changes in EEG and their corresponding remedies-
