In the International 10-10 System, electrode location names are standardized to provide a consistent method for electrode placement in EEG recordings. Here are the electrode location names according to the International 10-10 System:

1.      Fp1, Fp2: Frontopolar (Prefrontal)

2.     F3, F4: Frontal

3.     C3, C4: Central

4.    P3, P4: Parietal

5.     O1, O2: Occipital

6.    F7, F8: Frontal

7.     T3, T4: Temporal

8.    T5, T6: Temporal

9.    Fz: Midline Frontal

10. Cz: Midline Central

11.  Pz: Midline Parietal

The International 10-10 System provides a more detailed and standardized approach to electrode naming compared to the 10-20 System, allowing for precise electrode placement and accurate recording of EEG activity from specific brain regions.

International 10-10 System Rules

The International 10-10 System is an extension of the 10-20 System that provides more detailed electrode placement guidelines for EEG recordings. Here are some key rules of the International 10-10 System:


1.      Naming Convention:

o    Electrodes are named based on their location relative to the midline and hemisphere.

o    The letter prefix indicates the region of the head (e.g., F for frontal, C for central).

o    The number suffix indicates the percentage distance from the midline (e.g., 10% or 20%).

2.     Consistency:

o Electrode names are consistent with their anatomical locations, allowing for easy identification of recording sites.

o  The naming convention ensures uniformity in electrode placement across different EEG recordings.

3.     Detailed Naming:

o    The system provides more detailed electrode names compared to the 10-20 System, allowing for precise localization of brain activity.

o    Electrodes are named based on their specific positions within each region, providing a comprehensive mapping of the scalp.

4.    Improved Accuracy:

o  The International 10-10 System enhances the accuracy of electrode placement by specifying locations with greater precision.

o  Clinicians and researchers can target specific brain regions more effectively for EEG data collection and analysis.

5.     Standardization:

o  Standardized rules for electrode naming and placement promote consistency in EEG recordings within and across institutions.

o    Adhering to the 10-10 System guidelines ensures that EEG data can be interpreted accurately and compared reliably.

6.    Compatibility:

o    The International 10-10 System is compatible with the 10-20 System, allowing for integration of both systems in EEG studies.

o    Researchers and clinicians can choose the system that best suits their needs while maintaining compatibility with established practices.

By following the rules of the International 10-10 System, EEG technicians and researchers can achieve precise and standardized electrode placement, leading to accurate recording and interpretation of brain activity in EEG studies.

Ocular Artifacts

Dr. Rishabh Pathak
Ocular artifacts in EEG recordings are commonly caused by movements of the eyes, such as blinking, eye flutter, and eye movements associated with eye opening and closure. These artifacts can mimic epileptiform discharges and other EEG patterns, making them important to recognize and differentiate.  Nature of Ocular Artifacts : o    Ocular artifacts are primarily due to the movement of the electrical dipoles created by the eyes, particularly during activities like eye opening, closure, and directed gaze. o    The movement of these dipoles generates changing electrical fields that appear as EEG activity, with characteristics such as slow waves and spikes. o    Ocular artifacts are typically limited to the frontal region and do not extend into the central region of the brain. 2.      Differentiation from Epileptiform Discharges : o   Ocular artifacts can sometimes appear as bifrontal spike and slow wave complexes, resembling inter...

Unrestricted Sampling

Dr. Rishabh Pathak
Unrestricted sampling, also known as simple random sampling, is a fundamental sampling technique where each element in the population has an equal and independent chance of being selected for the sample. In unrestricted sampling: 1.     Equal Probability of Selection : §   In simple random sampling, every element in the population has an equal probability of being chosen for the sample. This ensures that each unit is selected independently of other units, without any bias towards specific elements. 2.     Random Selection : §   The selection of sample elements is done randomly, without any systematic pattern or predetermined order. This randomness is essential to ensure that the sample is representative of the population and to minimize selection bias. 3.     Independence of Selection : §   Each selection is made independently of previous selections, meaning that the inclusion or exclusion of one element does not influence the ...

New Freezing of Gait Questionnaire (N-FOGQ)

Dr. Rishabh Pathak
The New Freezing of Gait Questionnaire (N-FOGQ) is a specific assessment tool used in clinical research and practice to evaluate freezing of gait (FOG) in patients with Parkinson's disease and related movement disorders. Here is an overview of the N-FOGQ: 1.       Definition : o   The N-FOGQ is a self-reported questionnaire designed to assess the frequency, severity, and impact of freezing of gait episodes experienced by individuals with Parkinson's disease and atypical parkinsonism. o   It consists of a series of questions that capture various aspects of freezing episodes during walking and mobility tasks, providing clinicians and researchers with valuable information about the presence and characteristics of FOG in patients. 2.      Purpose : o   FOG Assessment : The N-FOGQ serves as a standardized tool for quantifying and characterizing freezing of gait symptoms in individuals with Parkinson's disease, allowing for systemati...

Distinguishing Features Ictal Epileptiform Patterns

Dr. Rishabh Pathak
The distinguishing features of ictal epileptiform patterns are critical for differentiating them from other EEG activities and for accurate seizure diagnosis. Here are the key distinguishing features outlined in the document: 1.      Stereotyped Nature : Ictal patterns are often stereotyped across seizures for the individual patient. This means that the same pattern tends to recur in different seizures, which aids in identification. 2.    Evolution of Activity : A hallmark of ictal patterns is their evolution, which can manifest as changes in frequency, amplitude, distribution, and waveform. This evolution is a key feature that helps differentiate ictal patterns from other types of EEG activity, such as normal rhythms or artifacts. 3.   Behavioral Changes : Ictal patterns are typically associated with stereotyped behavioral changes. While some seizures may not exhibit obvious movements, the presence of behavioral changes is a significant indicator of s...
