We measured the concentration dependence of the ability of rats to identify odorants and compared these results with the calcium signals in the nerve terminals of the olfactory receptor neurons. Odorant identification remained far above random chance at all concentrations tested (between 0.0006% and 35% of saturated vapor). In contrast the calcium signals were much smaller than their maximum values at odorant concentrations less than 1% of saturated vapor. Extrapolation suggests that only a few spikes in olfactory sensory neurons may be sufficient for correct odorant identification.

This is due to their widespread activation by odor stimuli. We expressed channelrhodopsin-2 ...
Extreme rainfall activity in the Australian tropics reflects changes in the El Niño/Southern Oscillation over the last two millennia Denniston, Rhawn F.; Villarini, Gabriele; Gonzales, Angelique N.; Wyrwoll, Karl-Heinz; Polyak, Victor J.; Ummenhofer, Caroline C.; Lachniet, Matthew S.; Wanamaker, Alan D.; Humphreys, William F.; Woods, David; Cugley, John (2015-03)Assessing temporal variability in extreme rainfall events prior to the historical era is complicated by the sparsity of long-term ‘direct’ storm proxies. Here we present a 2200-yr-long, accurate and precisely dated record ...
