Whiskers, 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...
متن کاملDisrupted cortical map and absence of cortical barrels in growth-associated protein (GAP)-43 knockout mice.
There is strong evidence that growth-associated protein (GAP-43), a protein found only in the nervous system, regulates the response of neurons to axonal guidance signals. However, its role in complex spatial patterning in cerebral cortex has not been explored. We show that mice lacking GAP-43 expression (-/-) fail to establish the ordered whisker representation (barrel array) normally found in...
متن کاملEfferent Pathways in Sodium Overload-Induced Renal Vasodilation in Rats
Hypernatremia stimulates the secretion of oxytocin (OT), but the physiological role of OT remains unclear. The present study sought to determine the involvement of OT and renal nerves in the renal responses to an intravenous infusion of hypertonic saline. Male Wistar rats (280-350 g) were anesthetized with sodium thiopental (40 mg. kg(-1), i.v.). A bladder cannula was implanted for collection o...
متن کاملWhiskers 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 کاملPhenyldiguanide activates cardiac receptors to produce responses by involving three different efferent pathways in anaesthetized rats.
The present study was undertaken to determine the afferent and efferent pathways involved in the phenyldiguanide (PDG)-induced reflex response in rats. Intravenous (iv) injection of PDG (10 microg/kg), produced hypotension, bradycardia and apnea over a period of time. Bilateral vagotomy abolished the PDG-induced reflex changes. Atropine (2 mg/kg; iv) blocked only the bradycardiac response produ...
