Children who have complex communication needs can benefit from the use of a speech-generating device (SGD). Cognitive skills were identified as having an impact on the ability to navigate between levels of SGDs. This protocol describes the steps needed for Speech-language Pathologists to assess cognitive skills and navigational abilities.

The dry-land Barnes maze is widely used to measure spatial navigation ability in response to mildly aversive stimuli. Over consecutive days, performance (e.g. latency to locate escape cage) of control subjects improves, indicative of normal learning and memory. Differences between rats and mice necessitate apparatus and methodology changes that are detailed here.

Dynamic navigation systems (DNS) provide real-time visualization and guidance to the operator during endodontic access cavities preparation. The planning of the procedure requires three-dimensional imaging utilizing cone beam computed tomography and surface scans. After the export of the planning data to the DNS, access cavities can be prepared with minimal invasion.

FAQs
Animals can compare environmental signals, including light, odors, landmarks, or magnetic fields, with information about their own orientation and movement. This combination helps them select a direction while accounting for their current position. The balance between external and internal information allows navigation to remain effective across different environments and supports behaviors such as homing, migration, and foraging.
These strategies rely on different sources of guidance. Taxis directs movement in relation to a cue, whereas landmark recognition uses identifiable environmental features. Route learning depends on remembering a path, while path integration uses accumulated information about movement and orientation. Their differences show how animals can reach locations through immediate sensory guidance, learned spatial information, or internal movement tracking.
A navigation strategy works only when an organism can obtain and use suitable information from its surroundings. Differences in sensory abilities affect whether an animal can rely on light, odors, landmarks, or magnetic fields. Environmental variation likewise changes which cues are available, so animals may adjust their paths or depend on a different strategy to reach an important location.
Comparing strategies reveals how organisms transform sensory information into movement decisions. It can show whether successful travel depends mainly on external cues, spatial memory, or information about movement and orientation. Such comparisons also clarify how nervous systems support coordinated behavior, allowing scientists to connect navigation mechanisms with adaptive outcomes in varied biological settings.
These behaviors require animals to locate, revisit, or choose places that matter for survival and reproduction. During migration, navigation supports movement between important regions; during foraging, it helps animals find resources. Homing depends on returning to a significant location, while habitat selection requires choosing a suitable environment. Studying the strategies used in each context links movement patterns to ecological function.
Navigation provides a way to study how nervous systems connect sensation, memory, orientation, and coordinated movement. Examining behaviors such as route learning or landmark recognition shows how environmental information can guide decisions and actions. This subject therefore connects sensory biology with behavior and ecology, while explaining how movement becomes adaptive in relation to an organism’s surroundings.
