Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Attention refers to the limited human ability to select some information for processing at the expense of other stimuli in the environment. Attention operates in all sensory modalities: vision, hearing, touch, even taste and smell. It is most often studied in the visual domain though. A common way to study visual attention is with a spatial cueing paradigm. This paradigm allows researchers to measure the consequences of focusing...

We discuss a novel method forviewpoint-rotation of visual stimuli, and demonstrate using a mirror stereoscopethe three-dimensional percept of rotation-in-depth. The technique can be used to investigate the role of stereoscopic cues in encoding viewpoint-rotated figures.

Non-verbal communication extends beyond gestures and facial expressions to include vocal elements known as paralanguage. Paralanguage consists of non-verbal vocal cues such as pitch, loudness, speech rate, pauses, and non-verbal vocalizations like laughter, sighs, and moans. These elements not only accompany speech but also provide critical emotional and contextual information.The Role of Paralanguage in CommunicationParalanguage adds depth to spoken language by conveying emotions and...

Fundamental, yet unique properties of the rodent olfactory system have led to its increasing study among biologists. A relatively simple assessment of its function is then also needed. Here we describe sensitive tests for the characterization of mouse olfactory sensitivity and preference.
FAQs
After a volatile molecule enters the nasal cavity, it binds to an odorant receptor on a sensory neuron. That interaction triggers a neural signal, which carries information for processing in the brain. The receptor-neuron step therefore links a chemical feature of the environment with the nervous system’s interpretation of an odor.
Distinct odor perceptions arise when different volatile molecules interact with odorant receptors and generate neural signals that the brain processes as particular odors. This sequence connects molecular detection with sensory interpretation. It also allows organisms to extract biologically relevant information from chemical signals associated with food, predators, potential mates, or other organisms.
Volatility enables odorant molecules to enter the nasal cavity, where they can contact sensory neurons and initiate signaling. Without access to the detection system, the chemical information would not be converted into a neural response. This property helps organisms obtain information about nearby environmental conditions and other organisms through smell.
These cues can guide several behaviorally important responses, including locating food, recognizing individuals, avoiding predators, and selecting mates. Their value comes from translating chemical information into neural signals that the brain can use in context. As a result, smell links sensory physiology with actions that affect feeding, social recognition, survival, and reproduction.
Research on olfactory communication connects sensory physiology with behavior, ecology, and evolution. Investigators can examine how receptor-based detection relates to what organisms do, how chemical information functions in ecological settings, and how these systems may have developed over time. This makes olfactory study useful across multiple levels of biological organization.
Olfactory cues provide a chemical basis for studying how animals obtain information about locations, environmental conditions, and other organisms. In particular, research can apply these signals to animal navigation and host detection, while also examining how chemical communication operates between organisms. These applications extend olfactory biology beyond sensory physiology into behavior and ecology.
Chemical signaling between organisms can be examined through the way volatile molecules are detected, converted into neural signals, and associated with behavior. The resulting information may support recognition, food finding, predator avoidance, or mate selection. Studying this process helps explain how organisms exchange biologically meaningful information through their environments.
