Subject: [neurocenas] Seminario Amita Seghal viernes 10 de Noviembre en el
IBioBA



Hola a todos!

Quería invitarlos al seminario titulado “Biology of bedtime: understanding
circadian rhythms and sleep” que nos brindará la Prof. Amita Seghal el
viernes 10 de Noviembre a las 12hs en el IBioBA (Godoy Cruz 2390
<https://maps.google.com/?q=Godoy+Cruz+2390&entry=gmail&source=g>).

Amita Seghal es actualmente John Herr Musser Professor y vice-directora del
Departamento de Neurociencias de la Perelman School of Medicine en la
University of Pennsylvania, es investigadora HHMI desde 1997 y dirige el
Programa de Cronobiología de UPenn. Amita ha realizado enormes
contribuciones al campo de los ritmos circadianos y el sueño utilizando
mayormente *Drosophila melanogaster* como organismo de estudio y visitará
brevemente Buenos Aires en camino al congreso latinoamericano de ritmos
circadianos que se llevará a cabo en Chile. No se pierdan la oportunidad de
escuchar a esta gran investigadora!

Acá va el resumen de su charla:

We are interested in the mechanisms that generate daily cycles of
physiology and behavior, especially sleep.  In addition to endogenous
circadian clocks, sleep is driven by a homeostatic process that ensures
sufficient amounts of sleep.  Our studies of circadian rhythms and sleep
use primarily a Drosophila model, which was invaluable for dissecting
molecular mechanisms of the clock conserved all the way to humans.  The
brain clock in Drosophila is located in discrete groups of neurons that
contribute in different ways to the behavioral sleep:wake cycle. However,
little is known about mechanisms that transmit time-of-day signals from the
clock through the rest of the brain to produce overt rhythms of sleep:wake.
We recently identified an “output” circuit, which transmits circadian
signals from the central clock cells, through non-clock peptidergic
neurons, to motor centers in the fly.  This circuit also regulates
metabolic rhythms.  In other work, we have identified factors that mediate
homeostatic regulation of sleep, those that control sleep amount and sleep
need.  In particular, we are interested in molecules that induce sleep.

Los esperamos!
Saludos!
