Distributed processing of sensory information in the leech. I. Input- output relations of the local bending reflex
SR Lockery and WB Kristan Jr
Department of Biology, University of California, San Diego, La Jolla, California 92093.
Sensory processing in the local bending reflex of the leech (Hirudo
medicinalis) was studied by examining the input-output relations of the
reflex. Sensory cells (P cells) were stimulated singly and in pairs and the
responses of the longitudinal muscle motor neurons were recorded. Each
pattern of single and paired P cell stimulation produced a unique pattern
of motor neuron response. In general, motor neuron response patterns were
consistent with the behavioral response of the whole animal.
