The Central Dogma

2019
Overview The central dogma of biology states that information encoded in the DNA is transferred to messenger RNA (mRNA), which then directs the synthesis of protein. The set of instructions that enable the mRNA nucleotide sequence to be decoded into amino acids is called the genetic code. The universal nature of this genetic code has spurred advances in scientific research, agriculture, and medicine. RNA Is the Missing Link between DNA and Proteins In the early 1900s, scientists discovered...

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...

The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians, "average" is commonly accepted for "arithmetic mean." Another measure of...

Source: Laboratory of Dr. Neal Abrams — SUNY College of Environmental Science and Forestry Transition metals are found everywhere from vitamin supplements to electroplating baths. Transition metals also make up the pigments in many paints and compose all minerals. Typically, transition metals are found in the cationic form since they readily oxidize, or lose electrons, and are surrounded by electron donors called ligands. These ligands do not form ionic or covalent bonds with the metal center,...

The central bank is responsible for conducting monetary policy in a country. Although central banks share similar responsibilities across countries, their organizational structures can vary.In the United States, the Federal Reserve System, known as the Federal Reserve or simply the Fed, is the central bank. The Federal Reserve is composed of three core components.The first component is the Federal Reserve Board of Governors, a government body located in Washington, D.C. It consists of seven...

Visual, olfactory, and other sensory signals converge within its interconnected neuropils rather than remaining isolated by modality. Recurrent neural circuits then process these inputs in relation to heading, movement goals, and environmental context. This integration allows the system to connect changing sensory conditions with an appropriate orientation or behavioral state before information reaches motor-control pathways.
Recurrent circuits provide pathways through which neural activity can influence ongoing processing within the system. In the central complex, this organization supports representations of heading, movement goals, and environmental context rather than a simple one-way transfer of sensory information. Such internal representations help maintain directional memories and support behavior that remains organized as an animal moves through its surroundings.
A heading representation gives the nervous system a reference for an animal’s directional state. When combined with sensory information and movement goals, it can help preserve directional memories and guide orientation toward relevant environmental features. This provides a neural basis for navigation using either landmarks or internal compass cues, linking perceived direction with subsequent behavioral choices.
Its circuits provide a way to examine how animals select actions from sensory information and internal states. Signals related to environmental context and movement goals can be integrated before influencing motor-control pathways. Studying this sequence helps clarify how perception becomes an organized behavioral response, including flexible changes in orientation or navigation when conditions and goals differ.
The system combines organized circuitry with experimental accessibility, making it practical for examining neural computation in an animal brain. Researchers can use it to connect circuit organization with orientation, navigation, directional memory, and behavioral flexibility. Its study also contributes to broader questions about how brain mechanisms linking perception to action have evolved.
Research on the central complex can address how animals orient, navigate, maintain directional memories, and respond to landmarks or internal compass cues. Because sensory information is linked to movement goals and environmental context, the system also helps explain behavioral flexibility. These outcomes connect neural circuit activity with observable decisions about movement and direction.
The central complex is conserved across arthropods, especially insects, so its organized circuitry offers a comparative context for studying brain mechanisms. Investigators can examine how neural systems link perception, directional information, and action across these animals. This makes the topic relevant not only to insect behavior, but also to broader questions about the evolution of computation and behavioral control.
