Spinal Locomotor Inputs to Individually - Identified Reticulospinal 1 Neurons in the Lamprey
23 Locomotor feedback signals from the spinal cord to descending brainstem 24 neurons were examined in the lamprey using the uniquely-identifiable reticulospinal 25 neurons, the Müller and Mauthner cells. The same identified reticulospinal neurons 26 were recorded in several preparations, under reduced conditions, to address whether 27 an identified reticulospinal neuron shows similar locomotor...

Locomotor feedback signals from the spinal cord to descending brain stem neurons were examined in the lamprey using the uniquely identifiable reticulospinal neurons, the Müller and Mauthner cells. The same identified reticulospinal neurons were recorded in several preparations, under reduced conditions, to address whether an identified reticulospinal neuron shows similar locomotor-related oscil...
متن کاملReticulospinal neurons receive direct spinobulbar inputs during locomotor activity in lamprey.
Reticulospinal neurons of the lamprey brain stem receive rhythmic input from the spinal cord during locomotor activity. The goal of the present study was to determine whether such spinal input has a direct component to reticulospinal neurons or depends on brain stem interneurons. To answer this question, an in vitro lamprey brain stem-spinal cord preparation was used with a diffusion barrier pl...
متن کاملResponses of reticulospinal neurons in intact lamprey to vestibular and visual inputs.
A lamprey maintains the dorsal-side-up orientation due to the activity of postural control system driven by vestibular input. Visual input can affect the body orientation: illumination of one eye evokes ipsilateral roll tilt. An important element of the postural network is the reticulospinal (RS) neurons transmitting commands from the brain stem to the spinal cord. Here we describe responses to...
متن کاملResponses of reticulospinal neurons in the lamprey to lateral turns.
When swimming, the lamprey maintains a definite orientation of its body in the vertical planes, in relation to the gravity vector, as the result of postural vestibular reflexes. Do the vestibular-driven mechanisms also play a role in the control of the direction of swimming in the horizontal (yaw) plane, in which the gravity cannot be used as a reference direction? In the present study, we addr...
