Higher Mental Functions of the Brain: Language01:10

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...
Neural Regulation01:37

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.
Language and Cognition01:27

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.
Neurons as Communicators of the Brain01:22

Neurons as Communicators of the Brain

Neurons, the fundamental units of the brain and nervous system, function as the primary transmitters of information throughout the body. Their ability to communicate through electrical and chemical signals is vital for every bodily function, from regulating the heartbeat to processing complex thoughts. Each neuron has three main components: the cell body (soma), dendrites, and an axon, each specialized to facilitate swift and efficient neural communication.

Components of Language01:24

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...
Lateralization01:28

Lateralization

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.

Area of Science:

  • Neuroscience
  • Linguistics
  • Cognitive Science

Background:

  • Co-speech gestures accompany speech, while emblems convey meaning independently.
  • Understanding the relationship between action and language processing is a key research area.
  • Neural processing of gestures is complex and not fully understood.

Purpose of the Study:

  • To review how the brain processes visual gestures.
  • To explore the relationship between gesture processing and language processing.
  • To understand the neural basis of gesture-language interaction in communication.

Main Methods:

  • Review of existing neuroimaging studies on gesture perception.
  • Analysis of brain responses to co-speech gestures and emblems.
  • Comparison of neural activity during gesture processing versus language processing.

Main Results:

  • Two complementary sets of brain areas are activated when viewing gestures.
  • These areas are involved in action understanding and language processing.
  • Emerging evidence suggests shared and distinct neural responses during communication.

Conclusions:

  • Gesture perception engages brain networks involved in both action and language.
  • Further research is needed to fully elucidate the neural mechanisms of gesture-language integration.
  • Understanding these neural processes is crucial for comprehending everyday communication.
