Summary
Mathematical and language abilities share overlapping brain networks, but also have distinct neural underpinnings. This study used Voxel-based Lesion Symptom Mapping in stroke patients to explore these relationships.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Neurolinguistics
Background:
- The relationship between mathematical ability and language processing is debated.
- Some research suggests shared neural processes, while others propose distinct systems.
Purpose of the Study:
- To investigate the neural basis of arithmetic and language comprehension.
- To determine if these cognitive functions rely on overlapping or distinct brain networks.
Main Methods:
- Voxel-based Lesion Symptom Mapping (VLSM) was used.
- 68 left hemisphere stroke patients were assessed on arithmetic and language comprehension tasks.
- Lesion data were analyzed to identify critical brain regions for each task.
Main Results:
- A significant correlation was found between arithmetic and language comprehension performance.
- Arithmetic performance was primarily associated with the left inferior parietal lobule (Brodmann areas 39 and 40).
- Language comprehension involved broader regions, notably the left middle and superior temporal gyri.
- Overlap in critical regions was observed, including the inferior frontal gyrus.
Conclusions:
- Arithmetic and language comprehension are supported by partially overlapping neural networks.
- These findings contribute to understanding the neural basis of mathematical ability and its connection to language.

01:10Higher 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...

01:27Language 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.
01:28Lateralization
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
01:05Cerebral Hemispheres
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...
01:24Components 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...
01:21Association Areas of the Cortex
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
