[Todos] Charla de tema interesante

[Pablo I. Tamborenea]

Hola,

Reenvío a todos en df este anuncio de una charla que se dará el viernes
en Santa Barbara.   Obviamente no es para que se tomen un avión ya mismo
sino porque puede ser útil dado el interés y auge de la biofísica.
(Tal vez le sirva a alguien para rastrear a la charlista.)

Saludos, Pablo

“Mechanical sensitivity in hair cells of the inner ear”

Abstract

Inner ear hair cells perform the first step of auditory processing –
they detect minute mechanical displacements due to the incoming sound
and transduce them into electrical signals via opening of mechanically
gated ion channels. These cells are operant in a viscous medium, but can
nevertheless sustain oscillations, amplify incoming signals, and support
spontaneous oscillations, indicating the presence of an underlying
active process that must pump energy into the system. We will present
latest results on the mechanisms of amplification, as well as means by
which individual hair cells tune their responsiveness to stimulus. We
have also been developing techniques to simultaneously track movements
of multiple hair bundles. We applied this method to characterize
spontaneous oscillations across the epithelium, to probe for any
correlations in their motion or patterns in their frequency
distribution. And finally, we will discuss the effects of extracellular
matrices as mechanical coupling elements, and their effects on
phase-locking between hair cells.
