Soto Vera, Jorge Ignacio; Alcayaga Urbina, Julio; Sanhueza, Magdalena (Frontiers Research Foundation, 2017)© 2017 Vera, Alcayaga and Sanhueza. Neurons from many brain regions display intrinsic subthreshold theta-resonance, responding preferentially to theta-frequency oscillatory stimuli. Resonance may contribute to selective ...

Excitation, inhibition, and suppression by odors in isolated toad and rat olfactory receptor neurons Sanhueza, Magdalena; Schmachtenberg, Oliver; Bacigalupo Vicuña, Juan (2000)Vertebrate olfactory receptor neurons (ORNs) exhibit odor-induced increases in action potential firing rate due to an excitatory cAMP-dependent current. Fish and amphibian ORNs also give inhibitory odor responses, manifested ...

Sanhueza, Magdalena; Bacigalupo Vicuña, Juan (2005)The amygdala complex is a heterogeneous group of temporal lobe brain structures involved in the processing of biologically significant sensory stimuli and in the generation of appropriate responses to them. The amygdala ...

Sanhueza Toha, Magdalena; Bacigalupo Vicuña, Juan (1999)Olfactory chemotransduction involves a signaling cascade. In addition to triggering transduction, odors suppress ion conductances. By stimulating with brief odorant pulses, we observed a current associated with odor-induced ...

Gouet, Camilo; Aburto, Belen; Vergara Montecinos, Cecilia; Sanhueza, Magdalena (2012)Activity-dependent synaptic plasticity underlies, at least in part, learning and memory processes. NMDA receptor (NMDAR)-dependent long-term potentiation (LTP) is a major synaptic plasticity model. During LTP induction, ...

Sanhueza, Magdalena; Fernandez-Villalobos, German; Stein, Ivar S.; Kasumova, Gyulnara; Zhang, Peng; Ulrich Bayer, K.; Otmakhov, Nikolai; Hell, Johannes W.; Lisman, John (2011)During long-term potentiation (LTP), synapses undergo stable changes in synaptic strength. The molecular memory processes that maintain strength have not been identified. One hypothesis is that the complex formed by the ...

Madrid, Rodolfo; Sanhueza, Magdalena; Alvarez, Osvaldo; Bacigalupo Vicuña, Juan (Biophysical Society, 2003)Olfactory receptor neurons (ORNs) respond to odorants with characteristic patterns of action potentials that are relevant for odor coding. Prolonged odorant exposures revealed three populations of dissociated toad ORNs, ...

Astorga, Guadalupe; Härtel, Steffen; Sanhueza, Magdalena; Bacigalupo Vicuña, Juan (2012)In Drosophila photoreceptors Ca2+-permeable channels TRP and TRPL are the targets of phototransduction, occurring in photosensitive microvilli and mediated by a phospholipase C (PLC) pathway. Using a novel Drosophila brain ...
