Whiskers aid anemotaxis in rats
Observation of terrestrial mammals suggests that they can follow the wind (anemotaxis), but the sensory cues underlying this ability have not been studied. We identify a significant contribution to anemotaxis mediated by whiskers (vibrissae), a modality previously studied only in the context of direct tactile contact. Five rats trained on a five-alternative forced-choice airflow localization ta...
متن کاملBiological effects of inhaled magnesium sulphate whiskers in rats.
Male Wistar rats were exposed to two types of magnesium sulphate whiskers by inhalation for six hours a day, five days a week, for four weeks (sub-chronic study), or for one year (chronic study) to clarify the biological effects of the whiskers. There were few whiskers detected in the rat lungs even at one day after the exposure, suggesting that they are dissolved and eliminated rapidly from th...
متن کاملExpression of heme oxygenase-1 in the lungs of rats exposed to potassium octatitanate whiskers.
OBJECTIVES Oxidative stress is thought to be the pathogenesis of pulmonary fibrosis induced by asbestos, and heme oxygenase-1 (HO-1) protects lung tissue against oxidative stress. We hypothesized that HO-1 is also associated with oxidative lung injury caused by exposure to potassium octatitanate whiskers (PT1), which is one of the asbestos substitutes. METHODS Male Wistar rats were administer...
متن کاملFast Feedback in Active Sensing: Touch-Induced Changes to Whisker-Object Interaction
Whisking mediated touch is an active sense whereby whisker movements are modulated by sensory input and behavioral context. Here we studied the effects of touching an object on whisking in head-fixed rats. Simultaneous movements of whiskers C1, C2, and D1 were tracked bilaterally and their movements compared. During free-air whisking, whisker protractions were typically characterized by a singl...
متن کاملActive touch sensing in the rat: anticipatory and regulatory control of whisker movements during surface exploration.
Animals actively regulate the position and movement of their sensory systems to boost the quality and quantity of the sensory information they obtain. The rat vibrissal system is recognized to be an important model system in which to investigate such "active sensing" capabilities. The current study used high-speed video analysis to investigate whisker movements in untrained, freely moving rats ...
