Noise from city disturbances is masked by sound arriving directly from lateral sources.
These previous studies either suggested only one sensitive brain area involved, i.e., a lateral occipital source [48], or were unable to demonstrate an inversion effect at the source level despite its presence at the sensor level [46].
The vertical region was first centered on the point of maximal intensity of the lateral point source, then the position of the point of maximal intensity of the medial point source was evaluated.
Incubation was in the dark with a lateral light source.
A lateral light source illuminated the plants and stem movement over time was recorded.
Depending on the initial angle of stem lean, the apical response to the lateral light source differed.
Directed migration of slugs towards light was tested by keeping the plates in the dark and providing a lateral light source.
In plants inclined at 30° and 45°, the apex first reoriented in the vertical plane (white squares), before then turning towards the lateral light source after 24 h (see additional file 1: movie #1).
The P. carbinolicus genes (Pcar_2989 Pcar2997) are only distantly related to the Geobacter and Desulfuromonas operons, but because they are similar to genes from a variety of species including D. acetoxidans, it is difficult to be confident about the lateral transfer source.
