Ecdysis: neural orchestration of a complex behavioral performance
Science (New York, N.Y.)
|March 11, 1977
Summary
Cricket molting involves complex, adaptable motor neuron activity. Analysis reveals a structured organization, extending simple motor control models to intricate behaviors like insect ecdysis.
Area of Science:
- Neuroscience
- Insect Physiology
- Motor Control
Background:
- Cricket ecdysis (molting) is a complex process requiring precise, adaptable motor neuron activity over hours.
- Understanding the neural control of such lengthy and plastic behaviors is crucial.
Purpose of the Study:
- To analyze the motor unit organization during cricket ecdysis.
- To determine if existing models of simple invertebrate motor programs apply to complex behaviors.
Main Methods:
- Analysis of identified motor units in crickets during ecdysis.
- Examination of the temporal output patterns of motoneurons.
Main Results:
- Cricket ecdysis exhibits a highly organized, three-layered motor unit infrastructure.
- The neural control system demonstrates significant plasticity throughout the molting process.
Conclusions:
- The "small system" paradigm can be extended beyond simple invertebrate motor programs.
- Cricket ecdysis provides a model for understanding sophisticated, adaptable behavioral control in invertebrates.

00:54What is Behavior?
10.2K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

16.7K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Overview
Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the...
