2022
Reaching is a fundamental skill that allows humans to interact with the environment. Several studies have aimed to characterize reaching behavior using a variety of methodologies. This paper offers an open-source application of transcranial magnetic stimulation to assess the state of corticospinal excitability in humans during reaching task performance.

Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...

Dynamic computer-aided implant surgery (DCAIS) is a controlled implant surgical placement method performed without a surgical template using optical control. The real-time intraoperative control of movement and position of the surgical device simplifies the procedure and gives more freedom to the surgeon, providing similar precision as static navigation methods.

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.

Nonconscious Mimicry Occurs when Affiliation Goals are Present

Source: Diego Reinero & Jay Van Bavel—New York University People are social chameleons and regularly engage in nonconscious behavioral mimicry. This occurs when an individual unwittingly imitates the behaviors of another person, such as crossing one's legs moments after a person sitting adjacent does so, or adjusting one's body posture to match a conversation partner. Rapport between two people increases behavioral mimicry, just as mimicry also increases rapport. Psychologists have posited...
FAQs
Sensory information helps an animal evaluate its current position and identify cues associated with a destination or resource. Spatial representations organize those cues into a usable layout, allowing the animal to compare possible directions rather than respond only to an immediate stimulus. Together, these processes support route calculation and help connect perception with appropriate movement.
Cognitive maps provide internal spatial representations that help animals relate locations, routes, and relevant environmental cues. Their importance becomes especially clear when an animal must reach a destination through a changing environment, because navigation can depend on relationships among places rather than a single visible cue. Studying these representations links behavior with learning and memory.
Ongoing feedback allows an animal to compare its movement with the intended route and adjust its actions when conditions change. An obstacle or altered environment can make a previously suitable path ineffective, requiring updated evaluation and action selection. This flexibility shows how goal-directed navigation combines stored spatial information with moment-to-moment behavioral correction.
Researchers examine how animals evaluate their position, use environmental cues, select routes, and modify movement as conditions change. Observations of these linked processes can reveal how spatial representations, memory, sensory information, and feedback contribute to behavior. The same framework also supports questions about how learning and motivation influence the choices animals make while pursuing a destination or resource.
Studies can show how an organism forms spatial representations, calculates routes, and selects actions in relation to a goal. They can also reveal how learning, motivation, and decision-making shape navigation across species. These outcomes provide behavioral context for investigating the neural circuits associated with navigation and for comparing how different organisms solve environmental challenges.
The behavioral framework offers a way to examine how sensory information, spatial representations, route calculation, and action selection work together. Those same functional problems matter in robotics and autonomous systems, where an artificial agent must relate its position to a destination and adjust movement when conditions change. Animal studies therefore provide a context for comparing biological and engineered navigation strategies.
