The circadian system alters thermoregulation depending on the time of day and feeding condition
The circadian rhythm of body temperature (Tb) is a well-known phenomenon. However, it is unknown how the circadian system affects thermoregulation. Food deprivation in mice induces a greater reduct…

The neurobiology of spontaneous actions and operant learning in Drosophila
Learning about the consequences of our actions (operant learning) is one of the major ways in which we learn to understand the world we live in. Despite our recent advances in the neurobiology of l…

Stress impairs decision-making in rats
Stress influences various types of memory, but its effects on other cognitive functions are relatively unknown. We investigated the effects of uncontrollable stress on subsequent decision-making in…

Temporal dynamics of travelling theta wave activity in infants responding to visual looming
A fundamental property of most animals is the ability to see whether an object is approaching on a direct collision course and, if so, when it will collide. Using high-density electroencephalograph…

Large-scale imaging of brain network activity from >10,000 neocortical cells
Large-scale recording from populations of neurons is a promising strategy in the study of complex brain function. Here we introduce a simple optical technique that simultaneously probes the calcium…

Cerebral and Spinal Modulation of Pain by Emotions
Emotions have powerful effects on pain perception. However, the brain mechanisms underlying these effects remain largely unknown. In this study, we combined functional cerebral imaging with psychop…

Functional presynaptic α6-containing nicotinic acetylcholine receptors participate in nicotine reward in the VTA: where and how
In the ventral tegmental area (VTA), α6-nAChRs express abundantly, but their location, function, pharmacology, and roles in cholinergic modulation of dopaminergic (DA) neurons remain elusive….
