Oriented Surfaces

A surface is called orientable if a consistent choice of unit normal vector can be made at every point on the surface. A thin soap film stretched across a wire loop provides a familiar example. The film separates the air on one side from the air on the other, so one side can be selected as positive and the opposite side as negative. Once this choice is made, a unit normal vector can be assigned smoothly across the entire surface.At each point on the soap film, a unit normal vector points...

Location and Orientation of the Heart

2024
The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Making Choice Chambers ExpandBefore beginning the experiments, use one of the Sharpies from the lab table to trace a line around the circumference of the bottom of both bottles. One line should be 1 cm from the base of the bottle and the other should be 1.5 cm from the base of the bottle. Use a razor blade to make a small cut in each bottle at the mark. Then, insert the scissors and carefully cut along the line until the bottoms of the bottles are removed completely. Fit one bottle bottom into...

Detection of Architectural Distortion in Prior Mammograms via Analysis of Oriented Patterns

We demonstrate methods for the detection of architectural distortion in prior mammograms. Oriented structures are analyzed using Gabor filters and phase portraits to detect sites of radiating tissue patterns. Each site is characterized and classified using measures to represent spiculating patterns. The methods should assist in the detection of breast cancer.
FAQs
Animal orientation depends on combining several sensory cues rather than relying on one source of information. External signals may include landmarks, light patterns, odors, sound, gravity, or Earth’s magnetic field. Internal motion signals and stored spatial information add information about movement and place, allowing neural circuits to integrate inputs before directing behavior.
Internal motion signals and stored spatial information provide a distinct contribution from environmental cues. They supply information associated with the animal’s own movement and previously retained spatial information, while landmarks or odors provide surrounding references. Studying both sources helps neuroscience examine how nervous systems combine self-related and external information during orientation.
Neural circuits are important because they transform sensory inputs and internal information into directed behavior. This transformation provides a way to investigate how nervous systems encode direction, distance, and location. Examining these processes connects measurable environmental cues with the spatial information that supports movement, survival, and reproduction across animal species.
Research on animal orientation can reveal how brains encode direction, distance, and location across species. It also provides a framework for examining sensory integration, the process of combining information from multiple sources, and its relationship to behavior. These findings help connect neural activity and information processing with how animals move through their surroundings.
A broad investigation should consider landmarks, light patterns, odors, sound, gravity, and Earth’s magnetic field, along with internal motion signals and stored spatial information. These cues represent environmental and internally available sources of spatial information. Considering them together supports analysis of how nervous systems use multiple inputs rather than treating orientation as a single-cue process.
Animal orientation can inform biologically inspired autonomous systems by providing examples of how nervous systems combine environmental cues, internal motion signals, and stored spatial information. Research focused on direction, distance, and location may guide the study of autonomous systems that use sensory integration and spatial information to support directed movement through an environment.
