Language and Cognition

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Neural Regulation

Neural Regulation

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.

Higher Mental Functions of the Brain: Language

Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Language

Language

Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.
Corballis and Suddendorf (2007) and Tomasello and Rakoczy (2003) highlight the role of language in...

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Components of Language

Components of Language

Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs. “eh”). Phonemes combine to...

Summary

Obesity treatments remain limited, with drugs causing side effects due to interconnected molecular pathways. This study uses graph theory to explore molecular signaling, revealing "molecular polysemy" for better drug design.

Area of Science:

Biochemistry and Systems Biology
Pharmacology
Computational Biology

Background:

Rising global obesity rates necessitate novel treatment strategies.
Current weight management drugs exhibit off-target effects impacting cardiovascular, behavioral, and cognitive functions.
The complex molecular networks governing ingestion control are not fully understood.

Purpose of the Study:

To explore molecular signaling pathways using graph theory.
To investigate the concept of "molecular polysemy" in biomolecular communication.
To inform the design of targeted obesity pharmacotherapies with reduced side effects.

Main Methods:

Application of graph theory to model molecular signaling networks.
Analysis of biomolecular interactions through a "language" analogy.
Conceptual framework for understanding "molecular polysemy".

Main Results:

Molecular signaling can be conceptualized as a language, with biomolecules acting as "words" with multiple meanings ("molecular polysemy").
This polysemy explains unintended side effects of current obesity drugs.
A new framework for understanding drug-target interactions in complex biological systems.

Conclusions:

Understanding "molecular polysemy" is crucial for developing effective and safe obesity medications.
Graph theory provides a valuable tool for dissecting complex molecular signaling.
Future drug design should consider the interconnected nature of molecular pathways to minimize off-target effects.
