In two-dimensional incompressible fluid flow, the continuity equation is essential for ensuring mass conservation, meaning that any change in fluid entering or exiting a region is balanced by a corresponding change elsewhere. For incompressible flow, where density remains constant, this requirement simplifies to the condition that the divergence of the velocity field must be zero. Mathematically, this is expressed as, where u and v represent the horizontal and vertical velocity components,...

Consider a control volume, such as a pipe with solid boundaries, through which fluid flows and changes direction due to the impulse exerted by the resulting force from the pipe walls. In steady flow, the mass of fluid entering the control volume at a given time, t, with velocity v1, is equal to the mass leaving after infinitesimal time dt, with velocity v2. During this process, the momentum of the fluid within the control volume remains constant over the time interval dt. By applying the...

An in vivo imaging protocol to monitor primary sensory axons following dorsal root crush is described. The procedures utilize wide-field fluorescence microscopy and thy1-YFP transgenic mice, and permit repeated imaging of axon regeneration over 4 cm in the PNS and axon interactions with the interface of the CNS.
FAQs
Proprioceptive signals provide information about the body's position, while motor signals relate visual information to intended movement. The dorsal visual stream combines these inputs with visual features such as location and object relationships, helping transform perception into coordinated behavior. This integration is important for actions that require the brain to align what is seen with how the body moves.
Motion, spatial location, and relationships between objects are central features processed by the dorsal visual stream. Considering these properties together allows the brain to represent changing scenes and the position of objects relative to one another. That combined information supports behavior directed toward targets, movement through surroundings, and responses to stimuli that are moving.
Its importance lies in linking visual analysis with motor coordination rather than treating perception as separate from behavior. Information about where objects are, how they relate to one another, and whether they are moving can be combined with body and movement signals. This enables actions such as reaching and grasping to be guided by current visual conditions.
Researchers can examine reaching, grasping, navigation, and responses to moving stimuli because these behaviors depend on spatially organized visual information and coordinated action. Studying such behaviors helps clarify how the brain converts visual input into movement. It also connects neural mechanisms with observable performance, making these actions relevant for models of perception and behavior.
These impairments show how disruption of the pathway can affect the use of visual information for action and spatial behavior. Optic ataxia and spatial attention deficits provide clinically relevant examples of altered dorsal-stream function. Their study can inform models of perception while also contributing to clinical assessment and approaches to rehabilitation.
Clinical research can use dorsal-stream damage and its associated impairments to connect brain function with difficulties in spatially guided behavior. Findings related to optic ataxia and spatial attention deficits may support assessment of affected abilities and help shape rehabilitation efforts. This work also tests broader models of how perception becomes coordinated action.
