What would increase the resolution of EEG spikes?

Increasing the resolution of EEG spikes involves enhancing the detail and accuracy with which the electrical activity of the brain is captured. Recording at a high sampling rate plays a crucial role in this process. When the sampling rate is elevated, more data points are gathered over the same period. This means that rapid fluctuations in the EEG signal, such as spikes, can be recorded more accurately.

A high sampling rate allows for a better identification of transient events like spikes, which may occur quickly and can easily be missed if sampled at a lower rate. This higher rate improves the temporal resolution, enabling the visualization of the shape and duration of spikes, which are essential for accurate diagnosis and analysis.

In contrast, reducing the sampling rate would lead to fewer data points and potential aliasing, where higher frequency signals are misrepresented. Similarly, using lower frequency filters would limit the range of frequencies captured, potentially obscuring important components of the EEG signal. Lastly, using fewer electrodes would decrease the spatial resolution and the ability to localize spikes accurately within the brain, further compromising the quality of the EEG data.
