Xviii. Cutaneous Sensory Mechanisms
We have previously reported1 that dogs raised in restriction cages from puppyhood to maturity have greater difficulty than normally reared littermates in performing a simple black-white discrimination and in subsequent reversal training. Since the restricted dogs had some patterned visual stimulation in their cages, their difficulty in performing a discrimination and then utilizing it in a new ...
متن کاملSensory Mechanisms Related to Homing in Pigeons
Besides having a well-developed vestibular system, pigeons possess a gravity and inertia sensitive system mediated by displacement of the viscera, presumed to stimulate mesenteric mechanoreceptors. Classical conditioning experiments confirm a sensitivity to atmospheric pressure changes. Failure to demonstrate a magnetic field orientation sensitivity in an instrumental conditioning situation is ...
متن کاملTransduction mechanisms in airway sensory nerves.
The induction of action potentials in airway sensory nerves relies on events leading to the opening of cation channels in the nerve terminal membrane and subsequent membrane depolarization. If the membrane depolarization is of sufficient rate and amplitude, action potential initiation will occur. The action potentials are then conducted to the central nervous system, leading to the initiation o...
متن کاملSensory Feedback Mechanisms in Performance Control
Four interpretations of the manner in which sensory feedback may be involved in regulation of skilled performance are reviewed. For the serial chaining (SC) and closed-loop (CL) mechanisms, response selection is assumed to occur on the basis of peripheral feedback from preceding correct and incorrect responses, respectively; for the ideo-motor ( IM) and fractional anticipatory goal response (ro...
متن کاملThe efficacy of dentine adhesive to sclerotic dentine.
OBJECTIVE To evaluate the effect of a dentine bonding system to sclerotic dentine in comparison with normal dentine. METHODS The efficacy of the dentine bonding system to sclerotic dentine was examined by measuring wall-to-wall polymerization contraction gap width. The dentine cavity wall was pretreated with an experimental dentine bonding system with and without a dentine primer. The dentine...
