>Life flows over time, the fourth dimension of life, which shapes our days, 
>months and years, and clocks tick in the brain to measure time. In 
>mammals, biological rhythms are controlled by the suprachiasmatic nuclei 
>(SCN) of the anterior hypothalamus which function as a master biological 
>clock. The SCN thus governs the sleep-wake cycle, as well as of endogenous 
>rhythms in behavioral, hormonal and immune functions. Other neural cell 
>groups act as “switches� of biological functions. For example, 
>orexin-containing neurons in the dorsolateral hypothalamus play a key role 
>in wake regulation and are involved in circuits underlying the transition 
>from sleep to wake. Despite the wealth of knowledge accumulated in the 
>last years on the regulation of the SCN and brain “switches�, the 
>effect exerted by inflammatory signalling on these cell groups has been 
>relatively neglected, though it can be implicated in diverse pathological 
>and physiological conditions. Paradigmatic is, in this context, a severe 
>neuroinflammatory condition represented by African trypanosomiasis or 
>sleeping sickness. This neglected parasitic disease, which is fatal if 
>uncured, is hallmarked in humans by alterations of the sleep-wake cycle. 
>Findings which implicate a dysregulation of brain clock/s in experimental 
>models of this disease will be discussed. On the other hand, in the 
>context of physiological conditions, a number of data in the last years 
>have pointed out that normal aging is hallmarked by low-grade chronic 
>inflammatory activity, with increased production of proinflammatory 
>cytokines peripherally and in the brain and decreased anti-inflammatory 
>mediators. A puzzling aspect of aging is represented by the frequent 
>dysregulation of endogenous biological rhythms, and especially of the 
>sleep/wake cycle, and data will be presented on aging-related changes of 
>brain clock/s. The talk will thus delineate an itinerary of research 
>focusing on neural-immune interactions in the brain timing machinery.

>The talk will give some highlights of the activities of IBRO, the world 
>federation of neuroscience societies, associations, groups 
>(<http://www.ibro.info>www.ibro.info). IBRO, a non-profit organization, 
>was founded in 1960 (at the birth of the modern era of the 
>“neurosciences�) to facilitate communication among neuroscientists 
>worldwide and to promote scientific exchanges and training in brain 
>research. Since the 1990s IBRO has concentrated efforts and resources on 
>the promotion of the neurosciences (and especially the training and 
>networking of young investigators) in disadvantaged countries of the 
>world. Main IBRO programs will be presented and discussed, with emphasis 
>on the Latin American community of neuroscientists.
