Such convergence has given birth to a plethora of new interdisciplinary business fields with neuro- prefix such as neuroeconomics, neuromarketing, decisions, categorising risks and rewards, neuroaccounting, neurogovernance, neuroethics, and interactions among economic agents. and neuroleadership. Such an exotic union Neuroeconomics research draws on the of science and the arts may provide better convergence of three major trends. First, using understanding of human nature and behaviour fMRI we can measure brain activity associated change. Imaging technologies such as functional with discrete cognitive events and study higher magnetic resonance imaging (fMRI) and positron cognitive processes like decision making and emission tomography (PET) reveal unseen neural reward evaluation. Second, by incorporating connections in the living human brain along economic variables into electrophysiological with brain wave analysis technologies such as experiments, we can encode motivationally quantitative electroencephalography (QEEG). We relevant information through novel recognition of can even theoretically link the brain (the physical neurons at multiple levels of processing pathways. organ) with the mind (the human consciousness Third, neuroeconomics draws on behavioural that thinks, feels, acts, and perceives) through an economics to consider psychological variables advanced computer to analyse these connections. into economic and decision-making models. As economists and business people always strive Neuroaccounting is a new way to for better, faster, cheaper means of production, scientifically view accounting and the brain’s and demand higher productivity from their central role in building economic institutions. employees through effective leadership and The measure of brain activity during economic supervision, neuroscience is relied upon to decision-making using neuroscientific methods provide answers to questions like: can prove useful for evaluating the desirability • How can we leverage our brain in of implementing new policies that run contrary business? to long-established accounting principles (2). • Capitalise/invest on the brain?

Applying neuroscience to discipline combines neuroscience, economics, marketing may form a basis for understanding and psychology; and uses research methods how human beings create, store, recall, and relate from cognitive neuroscience and experimental to information such as brands in everyday life. economics. It is “the application of neuroscientific Neuromarketers now use cognitive neuroscience methods to analyse and understand economically in marketing research that bears implications for relevant behaviour” (1). such as evaluating Malaysian J Med Sci.

In notable research emerging from Stanford consultant. Neuroleadership is the study of University, Carnegie Mellon University and the leadership through the lens of neuroscience and Massachusetts Institute of Technology, scientists explores central elements of leadership, including: are using fMRI to identify parts of the brain that (a) self-awareness (b) awareness of others, (c) influence buying decisions. insight, (d) decision making, and (e) influencing Neuroethics is the investigation of altruism (9). As a new field of study, neuroleadership in neuroeconomic research, which suggests that brings neuroscientific knowledge into the area of cooperation is linked to activation of reward leadership development, management training, areas (5). Investigations into such problems could education, consulting and coaching. Rock and in fact be among the most compelling within his collaborator Jeffrey M. Schwartz, a research neuromarketing.
