What role does the reference electrode play in EEG measurements and how does it impact the accuracy of the recorded brain activity?
The reference electrode in EEG measurements provides a stable point of comparison for the electrical signals detected by the other electrodes on the scalp. It helps to ensure that the recorded brain activity is accurately measured by providing a baseline for the electrical activity in the brain. This helps to minimize noise and interference, improving the accuracy of the recorded brain activity.

Can atavan inhibit the accuracy of an eeg?
Yes, Ativan (lorazepam) may affect the accuracy of an EEG (electroencephalogram) by potentially altering brain wave patterns and activity. It can suppress brain activity and lead to changes in EEG readings. It's important to inform healthcare providers if you are taking Ativan before undergoing an EEG to properly interpret the results.

What is the pursuit of an activity for external reward called in psychology?
The pursuit of an activity for external reward is called extrinsic motivation in psychology. It involves engaging in an activity to earn a reward or avoid punishment, rather than for the inherent satisfaction of the activity itself.

What is Positive at tip polarity?
Positive polarity at the tip indicates that the tip of the electrode has a positive charge compared to the reference electrode. This is commonly used in applications such as electrophysiology, where a positive signal is measured relative to a ground or reference point to detect neuronal activity or other biological signals.
What is standard hydrogen electrode?
The standard hydrogen electrode (SHE) is a reference electrode used in electrochemistry to measure electrode potential. It consists of a platinum electrode in contact with a solution of hydrogen ions at unit activity and surrounded by hydrogen gas at a pressure of 1 bar. The SHE has an assigned potential of 0 V at all temperatures.
What did Ida Henrietta Hyde invent?
Ida Henrietta Hyde invented a micro-electrode which allowed for precise measurements of electrical activity in living tissue. This invention was crucial for advancements in the field of electrophysiology and our understanding of how electrical signals are conducted in the body.
Why is the right leg the ground when taking an EKG?
In an electrocardiogram (EKG or ECG), the right leg is often designated as the ground electrode to minimize electrical interference and provide a stable reference point for the measurements. Grounding helps to reduce noise from external electrical sources and ensures that the heart's electrical activity is accurately captured by the other electrodes. This setup enhances the clarity of the EKG trace and contributes to consistent and reliable results.

How can one determine the activity coefficient in a solution?
The activity coefficient in a solution can be determined by measuring the concentration of the solute and the solvent, and using equations that relate the activity coefficient to these concentrations. Experimental methods such as vapor pressure measurements or conductivity measurements can also be used to determine the activity coefficient.

Accuracy can be acheived by day to day practice..Rome was not build in a day.So be sincere in your work without any distraction or tensions..U can get accuracy very soon..
How do you specify that the cell address will change if copied to another cell in excel?
No special activity is done to do this. Typing a cell reference in the normal way will result in a cell reference changing if it is copied. It is known as a relative reference. To restrict the change, you can make the cell mixed or absolute. See the related question below.No special activity is done to do this.

The principles of pH meter?
When you place the PH electrode in a PH unknown solution you'll find that an electrical potential difference is produced. THIS IS DUE TO: Difference of H+ ion concentration between the test solution and the glass bulb electrode (part of PH electrode that is sensitive to H+ ion concentration) After that the potential difference of the reference electrode (another part of PH electrode) is measured and compared to the potential of the glass bulb electrode by means of a meter. results are read from 0-14 The porous glass of the electrode prevents the H+ ions to diffuse from both sides, but allows the exchange of Na+ ions (contained in the silicates of the glass) with the external solution, for keeping the continuity ot this electrical system. The H+ activity difference between the solution inside the electrode and the external one is measured as electric potential difference, then, converted in pH units (0-14) by the instrument.
