INTRODUCTION: Emotional reactivity and sleep constitute key dimensions of bipolar disorder. Emotional reactivity referred to emotion response intensity and emotion response threshold. Higher emotion reactivity is described during both mood episodes and periods of remission in bipolar disorder. As well, sleep disturbances are described during both acute episodes and euthymic periods in bipolar disorder. Links between sleep and emotion regulation start to be studied in general population.

In mammals the neonatal period is a time of significant social interaction. This is true even in solitary species as females spend a significant amount of time nursing and caring for their offspring. In social species interactions may also include the father, older siblings and extended family members. This period is a time of significant development, including organization of the central nervous system, and therefore a time when the degree and type of social interaction influences the development and expression of social behavior in adulthood.

Major depressive disorder (MDD) is associated with a high rate of developing serious medical comorbidities such as cardiovascular disease, stroke, dementia, osteoporosis, diabetes, and the metabolic syndrome. These are conditions that typically occur late in life, and it has been suggested that MDD may be associated with "accelerated aging." We review several moderators and mediators that may accompany MDD and that may give rise to these comorbid medical conditions.

Two decades ago, experimental social psychologists became interested in the emotion of passionate love, "the desire for union with another." Recently, sex researchers have begun to focus on sexual desire, "the desire for sexual union with another," or the loss thereof. In this paper we review what experimental social psychologists have learned about the nature of passionate love in the last two decades and contrast their view of passion with that of sex researchers, especially with regard to the role that anxiety plays in the intensification/diminution of passion.

Love is a complex neurobiological phenomenon, relying on trust, belief, pleasure and reward activities within the brain, i.e., limbic processes. These processes critically involve oxytocin, vasopressin, dopamine, and serotonergic signaling. Moreover, endorphin and endogenous morphinergic mechanisms, coupled to nitric oxide autoregulatory pathways, play a role. Naturally rewarding or pleasurable activities are necessary for survival and appetitive motivation, usually governing beneficial biological behaviors like eating, sex, and reproduction.

INTRODUCTION: Love is a complex emotional state which is difficult to define. Considering anthropological studies, this feeling can now be divided into three distinct behaviors: lust, attraction for a specific partner and conjugal or filial attachment. STATE OF ART: For each, recent findings have contributed to identify specific neuronal networks which are interconnected as shown by common activation of limbic and paralimbic systems. A major role of arginine/vasopressin and oxytocin has also been pointed out for mate choice and attachment promotion.

Cooperation based on reciprocal altruism has evolved in only a small number of species, yet it constitutes the core behavioral principle of human social life. The iterated Prisoner's Dilemma Game has been used to model this form of cooperation. We used fMRI to scan 36 women as they played an iterated Prisoner's Dilemma Game with another woman to investigate the neurobiological basis of cooperative social behavior.

Humans often sacrifice material benefits to endorse or to oppose societal causes based on moral beliefs. Charitable donation behavior, which has been the target of recent experimental economics studies, is an outstanding contemporary manifestation of this ability. Yet the neural bases of this unique aspect of human altruism, which extends beyond interpersonal interactions, remain obscure. In this article, we use functional magnetic resonance imaging while participants anonymously donated to or opposed real charitable organizations related to major societal causes.

Music is well known for its effect on human behavior especially of their bonding and empathy towards others. Music provokes one's emotion and activates mirror neurons and reward system. It also regulates social hormones such as steroid hormones or peptides, and increases empathy, pro-sociality and altruism. As a result, it improves one's reproductive success.
