The basal ganglia has received much attention over the last two decades, as it has been implicated in many neurological and psychiatric disorders, including Parkinson's disease (PD), Attention Deficit Hyperactivity Disorder (ADHD), Tourette's syndrome, and dystonia. Most of current basal ganglia research?in both animals and humans?attempts to understand the neural and biochemical substrates of ...

abstract background: premature infants are subjected to many painful procedures during care and treatment. the aim of this study was to assess the effect of music therapy on physiological and behavioral pain responses of premature infants during and after blood sampling. materials and methods: this study was a cross-over clinical trial conducted on 20 infants in a hospital affiliated to tehran ...

Surgical castration is a common management practice performed on male pigs to prevent the occurrence of boar taint. Surgical castration is known to cause physiological and behavioral changes in pigs indicative of pain-induced distress; however, it is commonly performed without pain relief. The objective of this study was to evaluate the effectiveness of carbon dioxide gas (CO(2)) anesthesia and...

A model of social interaction is outlined and used to interpret behavioral and physiological correlates of ostracism. Reported findings suggest that several physiological systems contribute to behaviors that are associated with ostracism and that these as well as other systems are involved in responses to being ostracized. The ideas discussed in this article suggest that future research should ...

We study the behavior and emotional arousal of the participants in an experimental auction, leading to an asymmetric social dilemma involving an auctioneer and two bidders. An antisocial transfer (bribe) which is beneficial for the auctioneer (official) is paid, if promised, by the winner of the auction. Some pro-social behavior on both the auctioneers' and the bidders' sides is observed even i...

It is widely expected that physiological and behavioral stress responses will be integrated within divergent stress-coping styles (SCS) and that these may represent opposite ends of a continuously varying reactive-proactive axis. If such a model is valid, then stress response traits should be repeatable and physiological and behavioral responses should also change in an integrated manner along ...

The sleep onset process (SOP) is a dynamic process correlated with a multitude of behavioral and physiological markers. A principled analysis of the SOP can serve as a foundation for answering questions of fundamental importance in basic neuroscience and sleep medicine. Unfortunately, current methods for analyzing the SOP fail to account for the overwhelming evidence that the wake/sleep transit...

Animals have evolved several chemosensory systems for detecting potentially dangerous foods in the environment. Activation of specific sensory cells within these chemosensory systems usually elicits an aversive behavioral response, leading to avoidance of the noxious foods. Although this aversive behavioral response can be adaptive, there are many instances in which it generates "false alarms,"...

Elephants use different thermoregulatory mechanisms that depend on the anatomical and morphological characteristics of species. The crevices wrinkles skin enhance water-retention capacity epidermis. highly vascularized ear is another region particular interest, as its movement vasomotor changes promote heat dissipation. Generally, these are modulated by hypothalamic center peripheral response a...

The current study aims at identifying how lateralized multisensory spatial information processing affects response monitoring and action control. In a previous study, we investigated multimodal sensory integration in response monitoring processes using a Simon task. Behavioral and neurophysiologic results suggested that different aspects of response monitoring are asymmetrically and independent...
