While both excitatory and inhibitory responses play a role in shaping projection neuron response, inhibitory responses may predominate (Olsen et al., 2010).
The African bullfrog (Pyxicephalus), which preys on relatively large animals such as mice and other frogs, has cone shaped bony projections called odontoid processes at the front of the lower jaw which function like teeth.
To visually represent the relationship between body-shape and swimming performance, we plotted the shape projections (from the PLS) against swimming performance (the score from PC1).
Additionally, after categorizing shape classes by the number of edges in their shape projections, we found that this edge number was also significantly predictive of detection difficulty.
Spike clusters were evaluated by consideration of their spike shapes, projections on principal component space (calculated independently for each recording session) and autocorrelation functions.
Also of note, the proportion of models having a specific number of edges in their shape projections appears to be relatively stable, regardless of population size or how K is set (See Additional file 1: Figure S6).
As stated in the Background section, light sheet illumination perpendicular to objective lens 2 corresponds to a line shaped intensity projection at the focal plane of objective lens 1.
Canines are present throughout the order but show remarkable variation in size, shape, projection, and function.
The working principle is based on the switch and measure principle in electrical capacitance tomography (ECT), and fan beam shape projection from light emitters.
