Abstract

Present paper investigates brain activity associated with reasoning required to identify necessities for achieving and maintaining desired goals and with motivation to act with such an intention. We used a 12 second video composed by 6 scenes of 2 seconds each shows a sleeping baby and a flying mosquito that may hurt the baby, creating the necessity to kill it and motivating a mother to think about possible ways of killing the mosquito. EEG was recorded while volunteers were seeing this video. We used LORETA analysis to identify the set of neurons enrolled in video analysis and comprehension, and correlation analysis to calculate the amount of information provided by each electrode about these. Principal Component Analysis of covariation was used to disclose how these neurons enroll themselves to solve each necessary task of treat recognition, motivation triggering and analysis of alternative choices of action. This analysis showed that 3 different components brain activity that provide distinct neural signatures for each scene analysis and comprehension and show that motivation is a very complex psychological concept supported by a widely distributed neural processing.

Finally, results and discussion here pointed to some very new hypotheses about modularity of neural processing supporting reasoning that must be taken with the caution deserved to first ideas. Because of this, data used to support all discussions in this paper is available in EEG book named EEG_Motivation.xls and how use information in this EEG book is provided in file EEG_BOOK.doc. Both files are available from the author by request. The use of the EEG book allows any one to check results presented here to draw his/her conclusions, agreeing or disaccording with present propositions. Any one is free to use the provided data once their origin is acknowledged. .

Keywords: Motivation, Decision-making, EEG, LORETA, Information, PCA, Complex reasoning.
