The failed mid-slope parts are dominated by sediment truncations from faults almost correlating with the orientation of head- and sidewalls of scars.
According to the proton NMR measurements carried out by Han et al. the orientation of head group is different between plasmenylcholines and phoshatidylcholines [11].
This could be accomplished by Hebbian plasticity between visual feature detectors and head direction cells [75,77], and would be consistent with the observation that visual cues control the orientation of head direction cell firing [25].
We show now with a supplementary figure that the head-to-head orientation and the relative orientation of head-domains to coiled coil stalks in the nine-membered ring are similar to those observed in the two other crystal structures presented in our manuscript that do not crystallize as rings (97-320 FE construct and WT 97-274 construct).
Although we did not detect a gross difference in the variability of inter‐head distances in the DDB complexes compared to dynein alone, it is conceivable that the interaction of dynactin with domain 3 of the dynein tail allosterically modulates the positions or orientations of the heads and thus biases the motor into a processive conformation.
The crossover points in the averaged data lie between the gaze deviation that observers judge to be direct when viewing a rotated head (roughly 6° in the same direction as the head) and the actual orientation of the head (30°).
While monkeys seem to lack a full-fledged TOM Andersonn et al., 1996) (Flombaum and Santos, 2005 for a different view), they are nevertheless able to establish joint attention with conspecifics, largely relying on head gaze, that is the orientation of peer head (=face).
In addition to the increase in intelligibility afforded by correct head orientation while using directional microphones, orientation of the head to a sound makes it easier to see cues such as lip movements that have been shown to aid speech detection (Grant & Seitz 2000; Grant 2001) as well as speech intelligibility (MacLeod & Summerfield 1987; Middelweerd & Plomp 1987).
In order to achieve head-pose estimation we use a feature vector based on skin detection to estimate the orientation of the head, which is discretised into 8 different orientations, relative to the camera.
"It knows the precise orientation of your head".
