Central pattern generators (CPGs) are circuits that generate organized and repetitive motor patterns, such as those underlying feeding, locomotion and respiration. We summarize recent work on invertebrate CPGs which has provided new insights into how rhythmic motor patterns are produced and how they are controlled by higher-order command and modulatory interneurons.

OBJECTIVE The main aim of the study is to investigate the mediator roles of locus of control and repetitive thinking in the known relationship between adult attachment patterns and depression, obsessive compulsive disorder (OCD) and social anxiety symptoms. Together with this aim we sought to generate an integrative point of view to these relationships using a cognitive framework. METHOD Ther...

This paper presents an eecient compilation technique to generate the local memory access sequences for block-cyclically distributed array references with aane subscripts in data-parallel programs. For the memory accesses of an array reference with aane subscript within a two-nested loop, there exist repetitive patterns both at the outer and inner loops. We use tables to record the memory access...

In the hypotrichous ciliated protozoan Oxytricha nova, approximately 95% of the micronuclear genome, including all of the repetitive DNA and most of the unique sequence DNA, is eliminated during the formation of the macronuclear genome. We have examined the interspersion patterns of repetitive and unique and eliminated and retained sequences in the micronuclear genome by characterizing randomly...

Neurons in vitro respond to repetitive injection of the same fluctuating input current with reproducible patterns of precisely timed action potentials. These spike patterns, called attractors, are robust against slow drifts in neuronal response properties that occur during experiments, the effects of intrinsic membrane noise, and small changes in the input. Larger variations in the input lead t...

Repetitive-element PCR (rep-PCR) with primers based on repetitive extragenic palindromic (REP) and enterobacterial repetitive intergenic consensus (ERIC) repeated DNA sequences was used for genomic finger-printing of Bartonella species. This technique was applied by using either extracted genomic DNA or preparations of whole bacterial cells directly. PCR fingerprints with either the REP-based p...

In this study, the authors reported a case of woman with severe compulsion who became pregnant during the Repetitive transcranial magnetic stimulation. We carried out Repetitive transcranial magnetic stimulation and behavior therapy simultaneously after repeated medications' refraction. The patient received 20 sessions 1 Hz Repetitive transcranial magnetic stimulation in right dorsolateral pref...

The operation of neuronal networks depends on the firing patterns of the network's neurons. When sustained current is injected, some neurons in the central nervous system fire a single action potential and others fire repetitively. For example, in Xenopus laevis tadpoles, primary-sensory Rohon-Beard (RB) neurons fired a single action potential in response to 300-ms rheobase current injections, ...

BACKGROUND The chicken is capable of adaptive locomotor behavior within hours after hatching, yet little is known of the processes leading to this precocious skill. During the final week of incubation, chick embryos produce distinct repetitive limb movements that until recently had not been investigated. In this study we examined the leg muscle patterns at 3 time points as development of these ...

Known transcription regulatory signals which generally act as transcription factor binding sites (TFs) differ significantly in their base composition. Therefore, their occurrence in a genome largely depends on the local base composition. In an attempt to initiate an all human genome analysis for the occurrence of potential TFs, we systematically analyzed the GC-content of distinct functional re...
