What are cortograms?

Cortograms are visual representations of the electrical activity of the brain, typically derived from electroencephalography (EEG) data. They display the amplitude and frequency of brain waves across different regions over time, allowing researchers and clinicians to analyze brain function and identify anomalies. Cortograms can be useful in studying various neurological conditions, brain responses to stimuli, and cognitive processes. They provide a dynamic view of brain activity, often presented in a time-frequency format.
