2. 6. Computer Simulation of the Neural Control of Locomotion in the Cat and the Salamander

   Author : Nalin Harischandra; Örjan Ekeberg; Silvia Gruhn; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Locomotion; Computer simulation; Central pattern generator; System identification; Gait transition; Sensory feedback; Spiking neural networks;

   Abstract : Locomotion is an integral part of a whole range of animal behaviours. The basic rhythm for locomotion in vertebrates has been shown to arise from local networks residing in the spinal cord and these networks are known as central pattern generators (CPG). READ MORE

4. 7. Neuronal Networks of Movement : Slc10a4 as a Modulator & Dmrt3 as a Gait-keeper

   Author : Martin Larhammar; Klas Kullander; Leif Andersson; Åsa Wallén-Mackenzie; Robert Fyffe; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Synaptic vesicle transporter; Neuromodulation; Dopamine; Central Pattern Generator; Locomotion; Gait; Horse; Mouse; Commissural Inhibitory Interneuron; Neuroscience; Neurovetenskap;

   Abstract : Nerve cells are organized into complex networks that comprise the building blocks of our nervous system. Neurons communicate by transmitting messenger molecules released from synaptic vesicles. Alterations in neuronal circuitry and synaptic signaling contribute to a wide range of neurological conditions, often with consequences for movement. READ MORE

5. 8. Functional Imaging of Spinal Locomotor Networks

   Author : Chetan Nagaraja; Klas Kullander; Gilad Silberberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Central pattern generators; two-photon microscopy; locomotor rhythm; multiple rhythmicities; inhibitory neurotransmission; Neuroscience; Neurovetenskap;

   Abstract : Movement is necessary for the survival of most animals. The spinal cord contains neuronal networks that are capable of motor coordination and of producing different movements. In particular, a very reduced neuronal network in the spinal cord can produce simple rhythmic outputs even in the absence of descending or sensory inputs. READ MORE

6. 9. Neural circuits engaged in mastication and orofacial nociception

   Author : Tuija Athanassiadis; K-G Westberg; Sten Grillner; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rhythmical jaw movements; central pattern generator; trigeminal system; rabbit; Rat; c-Fos; nociceptors; muscle pain; muscle spindle afferents; glutamate; Neurophysiology; Neurofysiologi; fysiologi; Physiology;

   Abstract : A deeper understanding of both movement control and the effects of nociceptor inputs on our motor systems is critical for proper clinical diagnosis of musculo-skeletal dysfunctions and for development of novel rehabilitation schemes. In the jaw system, masticatory movements are produced by a central pattern generator (CPG) located in the brainstem. READ MORE

7. 10. Neural mechanisms for the control of posture, locomotion and steering : a behavioral, electrophysiological and modeling study in lamprey

   Author : Patriq Fagerstedt; Karolinska Institutet; Karolinska Institutet; []
   Keywords : reticulospinal; vestibular system; spinal cord; central pattern generator; reciprocal inhibition; fictive locomotion; fictive turning; electron microscopy; computer simulation; lamprey; dorsal fin;

   Abstract : When animals move around interacting with the environment, the nervous system has to solve several tasks simultaneously in order to produce and control the movements - notably propulsion, posture, balance, and associated movements. Basic motor tasks are controlled by neuronal networks organized into central pattern generators (CPGs) and reflexes, located in the spinal cord and brainstem. READ MORE
