The brain matters: effects of descending signals on motor control

The ability of nerve cords and spinal cords to exhibit fictive rhythmic locomotion in the absence of the brain is well-documented in numerous species. Although the brain is important for modulating the fictive motor output, it is broadly assumed that

The analysis of undulatory swimming gaits requires knowledge of the fluid forces acting on the animal body during swimming. In his classical 1952 paper, Taylor analysed this problem using a ‘resistive-force’ theory. The theory was used to charact

Although the neuronal circuits that generate leech movements have been studied for over 30 years, the list of interneurons (INs) in these circuits remains incomplete. Previous studies showed that some motor neurons (MNs) are electrically coupled to s

Owing to the complexity of neuronal circuits, precise mathematical descriptions of brain functions remain an elusive ambition. A more modest focus of many neuroscientists, central pattern generators, are more tractable neuronal circuits specialized t

Role of feedback loops in the scorpion circadian system

Autor: Günther Fleissner, W. Otto Friesen, Gerta Fleissner

Publikováno v: Neurocomputing. :607-614

Scorpions are nocturnal animals whose circadian activity rhythm is entrained via light/dark programs to the median and lateral eyes. Timing of light signals conveyed by the median eyes is modified by feedback from the circadian pacemaker. Using a sim
