Abstract
Purpose
The purpose of this paper is to check the geranium oil and anise oil effect to inhibit inflammation in brain cerebral cortex and hippocampus areas in depression.
Design/methodology/approach
Depression defined as psychiatric disease and chronic mild stress (CMS) model a well-known animal model of depression that represented major symptoms occurred in human depression. Geranium oil and anise oil selected for such a study to check their anti-inflammatory effect in brain tissues in depressed animal model.
Findings
The brain cerebral cortex and hippocampus neurotransmitters serotonin, dopamine, norepinephrine, gamma aminobutyric acid (GABA) and interleukin (IL)-10 significantly decreased (p < 0.001) while brain cerebral cortex and hippocampus IL-1ß, IL-6, tumor necrosis factor-alpha (TNF-α) and Ki-67 levels significantly increased (p < 0.001) in CMS rats compared to control. The oral intake of venlafaxine drug, anise oil and geranium oil significantly increased (p < 0.001) serotonin, dopamine, norepinephrine, GABA and IL-10 while significantly decreased (p < 0.001) IL-1ß, IL-6, TNF-α and Ki-67 levels to approach normal levels in brain cerebral cortex and hippocampus areas compared with CMS rats.
Originality/value
Antidepressants used in depression treatment but these drugs are either too expensive or had side effects. Folklore and complementary medicine used in different diseases treatment due to cheap and available source. Geranium oil and anise oil had anti-inflammatory effect in brain cerebral cortex and hippocampus areas in CMS rats.

Abstract
Many psychologists posit that intrinsic motivation generated by personal interest and spontaneous satisfactions is qualitatively different from extrinsic motivation generated by external rewards. However, the contemporary neural understanding of human motivation has been developed almost exclusively based on the neural mechanisms of extrinsic motivation. In neuroscience studies on extrinsic motivation, striatum activity has been consistently observed as the core neural system related to human motivation. Recently, a few studies have started examining the neural system behind intrinsic motivation. Though these studies have found that striatum activity is crucial for the generation of intrinsic motivation, the unique neural basis of intrinsic motivation has not yet been fully identified. I suggest that insular cortex activity, known to be related to intrinsic enjoyment and satisfaction, is a unique neural component of intrinsic motivation. In this chapter, I addressed the theoretical background to and empirical evidence for this postulation.

Abstract
Cognitive computing is part of AI and cognitive applications consists of cognitive services, which are building blocks of the cognitive systems. These applications mimic the human brain functions, for example, recognize the speaker, sense the tone of the text. On this paper, we present the similarities of these with human cognitive functions. We establish a framework which gathers cognitive functions into nine intentional processes from the substructures of the human brain. The framework, underpins human cognitive functions, and categorizes cognitive computing functions into the functional hierarchy, through which we present the functional similarities between cognitive service and human cognitive functions to illustrate what kind of functions are cognitive in the computing. The results from the comparison of the functional hierarchy of cognitive functions are consistent with cognitive computing literature. Thus, the functional hierarchy allows us to find the type of cognition and reach the comparability between the applications.

Abstract
Purpose
Autism spectrum disorder (ASD) has been studied as a neurodevelopmental disorder since Leo Kanner's early observations of abnormal head circumference in autistic children. In the past few years, there has been much progress made in elucidating the anatomical and functional abnormalities in ASD. This paper aims to summarise the extant research.
Design/methodology/approach
This paper provides a summary of relevant research findings in the neuroimaging of autism for the past 12 month period. Papers were identified using the Medline search terms: autism; ASD (functional); magnetic resonance imaging (MRI); neuroimaging; diffusion tensor imaging (DTI); and endophenotype.
Findings
Relatively recent techniques such as functional MRI and DTI have furthered the initial work derived from early histological and structural imaging studies. Even newer techniques, such as DTI tractography and support vector machine analysis, and other computer‐based learning methods have allowed us to move beyond regional variations in grey and white matter volume and study ASD as a disorder of connectivity, and of regional cerebral function and neural circuitry. Brain regions and neural circuits that are implicated in the core symptoms of ASD (deficits in social reciprocity, language and communication, and restricted and stereotyped interests) have been repeatedly shown to be abnormal in those individuals.
Originality/value
This paper aims to provide a background for clinicians to the current research and focuses on developments in the field of neuroimaging of ASD from the past year, which have generated further insights into the neurobiology of ASD.

Abstract
Recent years have brought significant advances in research on behavioral ethics. However, research on ethical decision making is still in a nascent stage. Our objective in this paper is twofold: First, we argue that the practice of mindfulness may have significant positive effects on ethical decision making in organizations. More specifically, we will discuss the benefits of “reperceiving” – a meta-mechanism in the practice of mindfulness for ethical decision making and we provide an overview of mindfulness research pertaining to ethical decision making. Subsequently, we explore areas in which neuroscience research may inform research on ethics in organizations. We conclude that both neuroscience and mindfulness offer considerable promise to the field of ethical decision making.

Abstract
Studies in psychology have long revealed that making personal choice involves multiple motivational consequences. It has only been recent, however, that the literature on neuroscience started to examine the neural underpinnings of personal choice and motivation. This chapter reviews this sparse, but emergent, body of neuroscientific literature to address possible neural correlates underlying personal choice. By conducting the review, we encourage future systematic research programs that address this topic under the new realm of “autonomy neuroscience.” The chapter especially focused on the following motivational aspects: (i) personal choice is rewarding, (ii) personal choice shapes preference, (iii) personal choice changes the perception of outcomes, and (iv) personal choice facilitates motivation and performance. The reviewed work highlighted different aspects of personal choice, but indicated some overlapping brain areas – the striatum and the ventromedial prefrontal cortex (vmPFC) – which may play a critical role in motivational processes elicited by personal choice.

Abstract
Purpose – Acknowledging that the field of neuroscience is expanding rapidly and the implication of recent neuroscientific advances on the study of politics is equally vast, this chapter will focus primarily on three key areas of convergence that have influenced the direction of neuropolitics: first, decision-making (emotions, preferences, and voting behavior); second, research on in-group/out-group relations, such as coalitional groupings and discrimination and prejudice; and, third, the rise of neuroeconomics.
Approach – This chapter is concerned with the intersection of political science and neuroscience and discusses how recent technological and theoretical developments in the latter are greatly contributing to the field of neuropolitics.
Findings – The insights generated by neuroscience permit the study of politics to be anchored on a scientific foundation for the first time. In turn, this opens the door to a renaissance in the political psychology subfield of political science, as the scientific origins of political behavior are revealed.
Research implications – The ongoing revolution in neuroscience is producing insights into international political behavior that is largely unacknowledged by political scientists.
Value – The implications for domestic and international policy are major. Fundamentally, this is because neuroscience allows us to comprehend better the origins of human political behavior.

Abstract
Purpose – This chapter focuses on individual differences in anxiety, by reviewing its neurobiology, cognitive effects, with an emphasis on decision-making, and recent developments in neuroeconomics.
Methodology – A review and discussion of anxiety and decision-making research.
Practical implications – This chapter argues that by making the step from emotional states to individual differences in emotion, neuroeconomics can extend its neurobiological roots and outreach its current clinical relevance.
Value of chapter – This chapter contributes to the literature on individual differences in emotion and their effects on decision-making, which is increasingly important in mainstream behavioral economics and neuroeconomics.

Abstract
Purpose
This study aims to review the relationship between neurological processes and financial behavior from an interdisciplinary perspective. Individual decision-making is influenced by cognitive and affective biases; hence, it becomes pertinent to understand the origin of these biases. Neurofinance is an emerging field of finance budding from neuroeconomics and explains the relationship between human brain activity and financial behavior, drawn from interdisciplinary fields, including neurology, psychology and finance.
Design/methodology/approach
This conceptual paper extensively reviews the extant literature and performs meta-analysis to attain its research objectives.
Findings
The paper highlights the use of neuroimaging techniques in mapping the brain areas to help understand the processes in the higher cognitive areas of brain. The paper raises some new questions regarding individual preferences and choices while making financial or non-financial decisions.
Originality/value
The special focus on dysfunctions arising in brain because of injury and their impact on decision-making is also a key point in this paper and is summarized using meta-analytic forest plot. The existing literature provides instances where emotional processing is altered by injury in brain and may lead to more advantageous decisions, especially in risky situations.
