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 کاملWhiskers, barrels, and cortical efferent pathways in gap crossing by rats.
Rats can readily be trained to jump a gap of around 16 cm in the dark and a considerably larger gap in the light for a food reward. In the light, they use vision to estimate the distance to be jumped. In the dark, they use their vibrissae at the farthest distances. Bilateral whisker shaving or barrel field lesions reduce the gap crossed in the dark by about 2 cm. Information from the barrel fie...

Male Wistar rats were exposed to two types ofmagnesium 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 the...
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...
