The behaviors of dairy cows, such as feeding, ruminating, running, resting (standing, lying), head-shaking, drinking, and walking, can indicate their health status. In this study, a multi-sensor was used to collect data cow's multi-behaviors for research on behavior recognition. Firstly, collar style acquisition system equipped with geomagnetic acceleration sensors the behavioral cows during da...

OBJECTIVE To document the resolution of oscillatory head movements following surgical realignment of the eyes in children with infantile esotropia and nystagmus. METHOD Retrospective review of 3 children who had infantile esotropia, nystagmus, and unexplained head shaking or head nodding. RESULTS Strabismus surgery restored ocular alignment and produced resolution of the head shaking in all...

OBJECTIVE To analyze perpetrator and medical evidence collected during investigations of infant abusive head trauma (IAHT), with a view to (a) identifying cases where injuries were induced by shaking in the absence of any impact and (b) documenting the response of infant victims to a violent shaking event. METHOD A retrospective study was undertaken of IAHT cases investigated by the Queenslan...

The authors investigated the mechanisms underlying the head shaking shown by some patients with congenital nystagmus (CN). In order to improve visual function by head shaking, a patient with CN must have some visual acuity loss due to retinal image motion created by the nystagmus; an abnormal vestibulo-ocular reflex (VOR); and the head shaking must be correlated with the nystagmus. The authors ...

The role of alpha-1 adrenergic mechanism in the shaking stress-induced adrenocorticotropic hormone (ACTH), and plasma noradrenaline secretion and pressor response were investigated using conscious rats. We also studied whether or not central corticotropin releasing hormone (CRH) is involved in the shaking stress-induced ACTH secretion. The shaking stress caused significant elevations of plasma ...
