Electrical Characteristics of Insect Mechanoreceptors
External direct coupled recordings from the neurons of the mechanosensory hairs of insects show nerve impulses and graded slow potentials in response to deformation of the hair. These slow potentials or receptor potentials are negative going, vary directly with the magnitude of the stimulus, and show no overshoot when returning to baseline. The impulses have an initial positive phase which vari...
متن کاملFunctional morphology of insect mechanoreceptors.
This paper reviews the structure and function of insect mechanoreceptors with respect to their cellular, subcellular, and cuticular organization. Four types are described and their function is discussed: 1, the bristles; 2, the trichobothria; 3, the campaniform sensilla; and 4, the scolopidia. Usually, bristles respond to touch, trichobothria to air currents and sound, campaniform sensilla to d...
متن کاملThe characteristics of the mechanoreceptors of the hip with arthrosis
Mechanoreceptors have been extensively studied in different joints and distinct signals that convey proprioceptive information to the cortex. Several clinical reports have established a link between the number of mechanoreceptors and a deficient proprioceptive system; however, little or no literature suggest concentration of mechanoreceptors might be affected by hip arthrosis. The purpose of th...
متن کاملElectrical Characteristics of the Membrane of an Identified Insect Motor Neurone
1. The electrical properties of the membrane of an identified locust motor neurone, the fast extensor tibiae in the metathoracic ganglion, have been investigated to determine: the distribution of excitable and inexcitable membrane; the impulse initiation zone; and the conduction velocity of the spike in the ganglion and in the axon. 2. The waveform of extracellularly recorded spikes indicates t...
متن کاملCharacteristics of hip joint mechanoreceptors in the cat.
2. Capsule afferents in the hip discharged only when the joint was rotated into its limit of movement along a single axis of rotation. 2. The optimal axis of rotation for an afferent was determined by the part of the capsule that was loaded by the rotation and by the location of the receptor in the capsule. Afferents were activated by rotations along the axes of abduction, adduction, and intern...
