Fixed Action Patterns

Fixed Action Patterns

A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Gastrulation

Gastrulation

Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata will form...

Area of Science:

Collective behavior
Animal social dynamics
Computational ethology

Background:

Understanding fish schooling requires models that capture complex interactions and decision-making.
Existing models often rely on metric interactions, potentially missing key topological aspects of social networks.

Purpose of the Study:

To develop and validate a novel topological model for fish collective behavior in annular domains.
To investigate the influence of perceptual limits, numerosity, and group size on schooling patterns.
To compare the proposed topological model with a traditional metric model.

Main Methods:

Simulated self-propelled particles on a discrete lattice representing fish.
Incorporated information exchange based on perceptual limits and numerosity for collective decision-making.
Analyzed spatio-temporal patterns using network observables and validated with zebrafish schooling experiments.

Main Results:

The topological model successfully reproduces characteristic fish schooling behaviors observed in experiments.
Group size and obedience parameters significantly affect schooling dynamics and network features.
The topological model provides superior interpretability of experimental data compared to the metric model.

Conclusions:

A topological approach offers a powerful framework for understanding fish collective behavior and decision-making.
Perceptual numerosity and spatial density are critical factors influencing schooling dynamics.
The proposed model advances our ability to predict and explain complex social behaviors in animal groups.
