Source: Laboratories of Sarah I. Gimbel and Jonas T. Kaplan— University of Southern California Understanding language is one of the most complex cognitive tasks that humans are capable of. Given the incredible amount of possible choices when combining individual words to form meaning in sentences, it is crucial that the brain is able to identify when words form coherent combinations and when an anomaly appears that undermines meaning. Extensive research has shown that certain scalp-recorded...

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...

Micro-dissection of rat brain into various regions is extremely important for the study of different neurodegenerative diseases. This video demonstrates micro-dissection of four major brain regions include olfactory bulb, frontal cortex, striatum and hippocampus in fresh rat brain tissue. Useful tips for quick removal of respective regions to avoid RNA and protein degradation of the tissue are given.

The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem. The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect various areas...
FAQs
These cortical regions contribute different but connected functions within language networks. Temporal areas help analyze sounds and meaning, frontal areas support planning and producing verbal output, and parietal regions participate in broader communication processes. Their coordinated activity allows language to operate across speech, comprehension, reading, and writing rather than depending on one isolated location.
The arcuate fasciculus is a pathway that transmits information among language-related regions. Its importance lies in supporting communication between areas that analyze language and areas that plan or produce verbal responses. Examining this pathway helps explain how distributed cortical activity becomes an integrated system for communication and why disruption can affect language performance.
Language functions often show left-hemisphere dominance, but this pattern is not identical in every individual. Both hemispheres can participate in language-related activity, and the organization of functions varies across people. This variability matters in psychological research and clinical interpretation because researchers must avoid assuming that the same language arrangement applies universally.
Researchers combine neuroimaging, lesion analysis, and behavioral testing to study language organization. Neuroimaging examines activity and connectivity, lesion analysis relates damaged areas to communication difficulties, and behavioral tests measure language performance. Using these approaches together provides complementary evidence about how regions and pathways contribute to speech, comprehension, reading, writing, and related processes.
Lesion analysis can connect injury in particular regions or pathways with changes in communication, helping researchers understand aphasia and other language disorders. Comparing affected abilities with behavioral test results reveals which aspects of language have been disrupted. This evidence also contributes to clinical assessment by linking observed communication problems with underlying brain organization.
They provide a neural basis for studying human cognition and communication. Psychological research can examine how language networks support meaning, verbal planning, and different forms of communication while also accounting for individual variation in hemispheric organization. This perspective connects observable language behavior with the distributed brain systems that help produce it.
Information from neuroimaging, lesion analysis, and behavioral testing can guide understanding of communication disorders and support clinical assessment. Identifying affected regions, connections, and language abilities helps characterize an individual’s difficulties. That characterization is relevant to rehabilitation because treatment planning can be informed by the specific communication processes disrupted after brain injury or disease.
