united, are readily applied to them, and immediately, the operator finds he has the head already firmly fixed in the grasp of the instrument, and that all the difficulty of locking has been avoided. Another important improvement is that the blades are so much more curved, and fit the head so closely, that 110 space is left between them and the presenting part of the head. By this, the difficult...

Psychophysical tasks for non-human primates have been instrumental in studying circuits underlying perceptual decision-making. To obtain greater experimental flexibility, these tasks have subsequently been adapted for use in freely moving rodents. However, advances in functional imaging and genetic targeting of neuronal populations have made it critical to develop similar tasks for head-fixed m...
This paper presents a methodology for automatically identifying human actions in either the frontal or the lateral view. By tracking the movement of the head of the subject over successive frames of a monocular grayscale image sequence, we recognize 1.2 different actions. The head is segmented automatically an each frame, and the feature vectors extracted. Input sequences captured from a fixed ...
Because of the remarkably improved image quality and wearability of modern head-mounted displays, a monitoring system using a head-mounted display rather than a fixed-site monitor for sonographic scanning has the potential to improve the diagnostic performance and lessen the examiner's physical burden during a sonographic examination. In a preclinical setting, 2 head-mounted displays, the HMZ-T...
