EEG analysis for pre-learning stress in the brain

Abstract

This paper deals with the relationship between pre-learning stress, long term memory, and EEG signals in the brain. Studying the effect of stress is very important especially in academic life for the students. Nowadays; there have been many recent methods evaluating the relationship between stress, learning and memory performance based on different techniques. The most common methods are conducted based on the biological response. Some of these methods have assessed the impact of stress based on biochemical effects by measuring specific hormones such as cortisol, adrenalin and glucocorticoids, or based on physiological effects such as blood pressure, heart rate, skin temperature. However, in all these methods, there are inconsistent findings due to the instability of hormones and a large number of related factors. The aim of this research is to discover the impact of pre-learning stress on long-term memory retrieval using EEG signals. The results indicate that there is a relationship between theta rhythm in the temporal lobe and long-term memory retrieval.
