Motor Control: Spinal Circuits Help Tadpoles See Clearly
A recent study suggests that animals can rely on internal expectations about their head movements, rather than vestibular sensations, to see what's in front of them.
متن کاملAssembly and function of spinal circuits for motor control.
Control of movement is a fundamental and complex task of the vertebrate nervous system, which relies on communication between circuits distributed throughout the brain and spinal cord. Many of the networks essential for the execution of basic locomotor behaviors are composed of discrete neuronal populations residing within the spinal cord. The organization and connectivity of these circuits is ...

neuronal populations that make up the lamprey CPG, like the locomotor circuits in higher vertebrates, are composed of three main classes of neurons: excitatory Pharmacology and Physiology interneurons that receive reticulospinal inputs for gener-University of Chicago ating the rhythmic output and that then distribute activity Chicago, Illinois 60637 to all neurons on the same side of the body; ...

is only observed indirectly. For example, we might have a spectrum and want to determine the species that produced it as well as their relative proportions. Or we may have sonar measurements of a containment tank and want to know whether it has an internal crack. Here is this issue’s homework assignment: given a blurred image and a linear model for the blurring, reconstruct the original image. ...
متن کاملOne fixates accurately in order to see clearly not because one sees clearly.
Binocular gaze was measured accurately under natural conditions with the Maryland Revolving Field Monitor to determine how visual-clarity affects gaze-accuracy. The gaze of 3 unrestrained, seated subjects (2 presbyopes and 1 myope) was recorded as they tapped 4 LEDs with a long, narrow rod cemented to a thimble worn on their index fingers. They wore positive contact lenses, permitting very clea...
