Communication

Communication

Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

Overview of Cell Signaling

Overview of Cell Signaling

Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...

Types of Signaling Molecules

Types of Signaling Molecules

In multicellular organisms, many molecules transmit signals between cells to pass information. These signals vary in complexity and include small peptides, nucleotides, steroids, fatty acid derivatives, and dissolved gases such as nitric oxide. Some signaling molecules diffuse through the plasma membrane to act locally between neighboring cells or travel long distances. Others remain attached to the cell surface, transmitting information to other cells only when they make contact. In some...

An Overview of the Endocrine System

An Overview of the Endocrine System

The endocrine system, a complex network of glands, orchestrates physiological balance within the body through the production and secretion of hormones. These hormones are chemical messengers in intercellular communication, acting as conduits between the secretory cells and distant target sites. They traverse the circulatory system by being released into the extracellular fluid, and their impact is specific to cells possessing receptors for a particular hormone.
The endocrine system collaborates...

Regulation of Hormone Secretion

Regulation of Hormone Secretion

Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.
Humoral stimuli,...

Summary

New research reveals diverse chemical signals, or pheromones, significantly impact vertebrate behavior. The main olfactory and vomeronasal systems show overlapping functions in detecting these signals.

Area of Science:

Neuroethology
Chemical Ecology

Background:

Vertebrate behavior is influenced by chemical signals, expanding the definition of pheromones.
The main olfactory system and vomeronasal organ, once thought independent, exhibit functional overlap in chemosignal detection.

Purpose of the Study:

To explore the expanding roles of pheromonal signals in vertebrate behavior.
To investigate the overlap and integration of olfactory and vomeronasal systems in mediating behavioral responses.

Main Methods:

Utilizing gene-targeted mice to study chemosensory systems.
Analyzing the cellular and molecular mechanisms of chemosensation.

Main Results:

Identification of novel pheromonal signal families.
