Abstract
In this study, it was aimed to investigate the primary mathematics teacher candidates' perceptions about the equal sign within the scope of neuroscience studies. To reveal their perceptions about the equal sign, three types of addition operations were asked to the participants: , , . Their brain waves were recorded by EEG device named as Neuron-Spectrum 4. Moreover, their ideas about the types of the questions were asked to support EEG data. As a result, it was found that the teacher candidates had more cognitive activity in parietal lobe while solving the questions of type two and three. In addition to this, they also showed more cognitive activity in frontal lobe for the type three questions. EEG results reveal that they had difficulty to answer these questions than the questions of type one as they also wrote on the interview form.

The joint declaration agreed by many countries stipulates that much more emphasis should be placed on the brain and the studies on the brain (Turkish Academy of Sciences, 2016)
Brain waves of the participants were recorded by EEG and the interview form was given to participants to evaluate the questions presented to them in three different categories
Summary
The most complex organ of a living organism, the brain, has remained as a fascinating puzzle since the existence (Morishima, Schunk, Bruhin, Ruff, & Fehr). The brain had failed to attract attention of people until the designation of the 1990s as the “decade of the brain” in the United States, which increased the importance placed on the brain across the world. Various countries such as Denmark and Sweden, following the United States, designated different years as the year of the brain, and, today, about 70 countries celebrate a certain period in a year as “the Brain Week” (Sekman, 2016). The growing interest and awareness towards the brain seem to contribute to inter-disciplinary studies in various fields. The joint declaration agreed by many countries stipulates that much more emphasis should be placed on the brain and the studies on the brain (Turkish Academy of Sciences, 2016)
