A condition characterized by abnormal posturing of the limbs that is associated with injury to the brainstem. This may occur as a clinical manifestation or induced experimentally in animals. The extensor reflexes are exaggerated leading to rigid extension of the limbs accompanied by hyperreflexia and opisthotonus. This condition is usually caused by lesions which occur in the region of the brainstem that lies between the red nuclei and the vestibular nuclei. In contrast, decorticate rigidity is characterized by flexion of the elbows and wrists with extension of the legs and feet. The causative lesion for this condition is located above the red nuclei and usually consists of diffuse cerebral damage. (From Adams et al., Principles of Neurology, 6th ed, p358)

The study of systems which respond disproportionately (nonlinearly) to initial conditions or perturbing stimuli. Nonlinear systems may exhibit "chaos" which is classically characterized as sensitive dependence on initial conditions. Chaotic systems, while distinguished from more ordered periodic systems, are not random. When their behavior over time is appropriately displayed (in "phase space"), constraints are evident which are described by "strange attractors". Phase space representations of chaotic systems, or strange attractors, usually reveal fractal (FRACTALS) self-similarity across time scales. Natural, including biological, systems often display nonlinear dynamics and chaos.

We investigated the central nervous coordination between singing motor activity and abdominal ventilatory pumping in crickets. Fictive singing, with sensory feedback removed, was elicited by eserine-microinjection into the brain, and the motor activity underlying singing and abdominal ventilation was recorded with extracellular electrodes. During singing, expiratory abdominal muscle activity is tightly phase coupled to the chirping pattern. Occasional temporary desynchronization of the two motor patterns indicate discrete central pattern generator (CPG) networks that can operate independently. Intracellular recordings revealed a sub-threshold depolarization in phase with the ventilatory cycle in a singing-CPG interneuron, and in a ventilation-CPG interneuron an excitatory input in phase with each syllable of the chirps. Inhibitory synaptic inputs coupled to the syllables of the singing motor pattern were present in another ventilatory interneuron, which is not part of the ventilation-CPG. Our ...

The buccal ganglia of Aplysia contain a central pattern generator (CPG) that mediates rhythmic movements of the foregut during feeding. This CPG is a multifunctional circuit and generates at least two types of buccal motor patterns (BMPs), one that mediates ingestion (iBMP) and another that mediates rejection (rBMP). The present study used a computational approach to examine the ways in which an ensemble of identified cells and synaptic connections function as a CPG. Hodgkin-Huxley-type models were developed that mimicked the biophysical properties of these cells and synaptic connections. The results suggest that the currently identified ensemble of cells is inadequate to produce rhythmic neural activity and that several key elements of the CPG remain to be identified ...

Mentor: Barreto, Jennifer. Reproductive-related behaviors, anxiety, cognition and addiction are known to be modulated by androgens. Besides hormone regulation of behavior, it is well known that neurotransmitters and neuropeptides are molecules underlying behavioral characteristics that are also under the influence of peripheral hormones. The long-term goal of the research program is focused in understanding the neurochemical substrates responsible for behavioral changes after exposure to synthetic androgens. Given that anabolic androgenic steroids (AAS) misuse is associated with multiple psychiatric symptoms and endocrine disruption, this study will provides critical data of the biochemical aspects of behavioral changes after androgen exposure, particularly in adolescents, where an increase misuse has been reported. We used pubertal rodents as animal models to determine the effect of chronic exposure to AAS in neurotransmitter and neuropeptide modulation in brain regions involved in anxiety, ...
When humans perform rhythmic upper and lower limb locomotor-like movements, there is an excitatory effect of upper limb exertion on lower limb muscle recruitment. To investigate potential neural mechanisms for this behavioral observation, we developed computer simulations modeling interlimb neural pathways among central pattern generators. We hypothesized that enhancement of muscle recruitment from interlimb spinal mechanisms was not sufficient to explain muscle enhancement levels observed in experimental data. We used Matsuoka oscillators for the central pattern generators (CPG) and determined parameters that enhanced amplitudes of rhythmic steady state bursts. Potential mechanisms for output enhancement were excitatory and inhibitory sensory feedback gains, excitatory and inhibitory interlimb coupling gains, and coupling geometry. We first simulated the simplest case, a single CPG, and then expanded the model to have two CPGs and lastly four CPGs. In the two and four CPG models, the lower limb CPGs

Afferent input has been shown to play a major role in our capacity to reactivate spinal circuits that generate coordinated rhythmic flexion and extension of the limb muscles in spinal cord injury patients. Our studies revealed that stimulation of sacrocaudal afferents (SCA) is a potent means for activating the locomotor central pattern generators (CPGs) in rodents spinal cords that lack the descending control from the brain. These studies showed that capacity of SCA to induce the locomotor rhythm depends on activation of sacrocaudal neurons the crossed and uncrossed projections of which, ascend through the ventral and lateral white matter funiculi (VF,VLF, LF, and DLF) to the limb innervating segments of the cord. The project examines the axonal projections, spatial distribution, organization and physiological properties of these sacrocaudal neurons and evaluates their role in the generation of afferent induced rhythmicity in the spinal cord. The studies are performed in collaboration with Dr. ...
When sinusoidal movements were artificially imposed on the tail region of the curarized spinal dogfish during fictive locomotion the coordinated burst pattern recorded in the ventral roots was effectively entrained to follow movement frequencies above as well as below the resting rate. The entrainment was characterized by: (1) a broad range of effective movement frequencies and amplitudes (down to a few degrees); (2) frequency-dependent timing of entrained bursts to the movement; (3) constant burst durations at low and moderate frequencies; (4) incomplete entrainment in response to high or low movement frequencies combined with a low amplitude; (5) entrainment was still present when mean position of movement was displaced laterally; (6) effects persisted when the tail region was devoid of skin and muscle tissue.

This article introduces the notion of cognitive pattern generators and suggests, by analogy with the central pattern generators of the motor system, that these pattern generators operate to organize neural activity underlying aspects of action-oriented cognition. It is further proposed that the basal ganglia are involved in the control of cognitive as well as motor pattern generators. Disorders of the basal ganglia may thereby contribute to neural circuit dysfunctions that are expressed as positive and negative symptoms of schizophrenia.. ...
A data pattern generator in which the address generation of a program counter (11) is controlled in accordance with an operation code and an operand read out of an instruction memory (12). An address/data pattern is generated in response to an address/data computing instruction read out of the instruction memory (12). Random logic patterns for testing a logic circuit are prestored in a data buffer memory (18) and are read out therefrom using an address created by an address pointer (19). The address generation of the address pointer (19) is controlled by control instructions and data written in a control instruction memory (22) and a load data memory (21) which are accessed by an address provided from the program counter (11).
Those of you interested in my last article on central pattern generator chips may also want to read a new piece Ive written for EE Times, this time on the use of CPGs in modular robots. It partly covers the salamander robot built by Auke Ijspeert and his team EPFL (and widely reported on after an article about it appeared in Science), but goes on to discuss how CPG-based locomotion may is being used to make Roombots: modular, self-organizing furniture that can walk around on its own.. This kind of work is an important step in the evolution of modular robotics, which I first got a chance to write about some years ago. There are very real problems to be grappled with, both in terms of the electronic and the mechanical design. This article explains how the EPFL team are handling the control side of this problem.. ...
Traditional function generators can output standard waveforms such as sine waves, square waves, and triangle waves. However, in actual test scenarios, in order to simulate the complex conditions of the product in actual use, it is often necessary to artificially create some irregular waveforms or add some specific distortion to a waveform. Traditional function generators can no longer meet the requirements and an arbitrary waveform generator may be a good option.. Arbitrary waveform generators can easily replace the function generators. They can source sine waves, square waves, and triangle waves like a standard function generator. In addition, they can also output pulse, noise, DC signal types, modulated signals, sweeps and bursts. Many arbitrary waveform generators currently on the market are equipped with arbitrary waveform drawing software. Through this software, theoretically, the arbitrary waveform generator can be remotely controlled to output all the signals required in the test ...

ed) the next time you restart it. But that also seems a bit silly. Since the generator computed the value to begin with, why bother sending it back? The generator could just save the value in a variable for the next time its needed. So whats the point?. Recall the fact we learned in Part 13, that the callbacks in a deferred can return deferreds themselves. And when that happens, the outer deferred is paused until the inner deferred fires, and then the next callback (or errback) in the outer deferreds chain is called with the result (or failure) from the inner deferred.. So imagine that our generator ...
