Reflex Effects of the Femoral Chordotonal Organ Upon Leg Motor Neurones of the Locust
The femoral chordotonal organ (FCO) in a hind leg of a locust monitors the position and movement of the tibia about the femur. It consists of a group of sensory neurones embedded in connective tissueExpand

Proprioceptive inputs to nonspiking local interneurons contribute to local reflexes of a locust hindleg
Local reflexes of a leg of the locust Schistocerca gregaria (Forskal) can be elicited by selective stimulation of a proprioceptor (the femoral chordotonal organ) at the femorotibial joint. MotorExpand

Somatotopic mapping of chordotonal organ neurons in a primitive ensiferan, the New Zealand tree weta Hemideina femorata: II. complex tibial organ
Most ensiferan insects possess sets of highly specialized chordotonal organs in the proximal tibiae to detect conspecific auditory/vibratory signals or approach of predators. To date, mostExpand

Structure of the auditory system of the weta Hemideina crassidens (Blanchard, 1851) (Orthoptera, Ensifera, Gryllacridoidea, Stenopelmatidae)
SummaryThe morphology and histology of the tibial auditory system of the New Zealand weta, Hemideina crassidens, are described. The groups of acoustic sensilla conform closely to the subgenual organ,Expand

The cardioregulatory system of crayfish: The role of circumoesophageal interneurones.
1. Interneurones located in the circumoesophageal commissures were found to control the activity of the cardioinhibitor and cardioaccelerator regularity neurones. 2. These interneurones (cardiacExpand

Innervation of the metathoracic femoral chordotonal organ ofLocusta migratoria
SummaryThe locust metathoracic femoral chordotonal organ is the largest sense organ in the hind leg. It has been intensively studied, and used as a model input system in studies of centralExpand

Elicitation and abrupt termination of behaviorally significant catchlike tension in a primitive insect.
Sustained steady contractural or catchlike tension (CT) occurs in the metathoracic extensor tibiae muscle of the primitive insect the weta (Orthoptera: Stenopelmatidae) during its characteristicExpand

Defense posture and leg-position learning in a primitive insect utilize catchlike tension.
The capability for conditioning of leg position, using loud sound as an aversive natural reinforcement, was examined in a primitive New Zealand insect, the weta (Orthoptera: Stenopelmatidae).Expand
