In each parent strain, receptors for the major pheromone component may be housed in the largest OSN in each sensillum, producing large amplitude spikes responding to the major component.
First we simulated spike trains responding to single stimuli.
Tonically spiking (also called 'fast spiking') neurons respond to a step input with spike trains of constant frequency.
Coping with the physical pressure of the athletics was going to be a considerable task in itself; but surrounded by publicity and anti-publicity, and perched on top of a dangerous political spike, she responded marvellously.
The spiking receptors respond to each input with a spike until the interval (IPI) is too small (they are refractory).
Most cortical excitatory neurons are not 'fast spiking', but respond to a step input with a spike train of slowly decreasing frequency, a phenomenon known as 'spike-frequency adaptation' (also called 'regular spiking').
It is well known that if the environment changes significantly, then place cell activity can undergo global remapping, and if the changes are small, then the place cells preserve the relative order of spiking and respond only by a regular change of their spiking rates (rate remapping) (Colgin et al., 2008; Allen et al., 2012).
The first five responding spikes were then averaged regardless of spike size to avoid any bias in spike selection.
We write (Y= y_{1}, ldots, y_{N})) where (y_{i} in{1, 2, ldots, K}), for the latent variables indicating which single stimulus each spike train is responding to.
As with male behavior, all F1 hybrid individuals exhibited intermediate phenotypes with equal spike amplitude OSNs responding to E or Z-11-tetradecenyl acetate.
