The (Spatial) Memory Game: Testing the Relationship Between Spatial Language, Object Knowledge, and Spatial Cognition
Published on: February 19, 2018
Patients with left-hemisphere epilepsy and atypical speech localization are verbally similar to those with right-hemisphere epilepsy. This finding impacts understanding of language function in epilepsy patients.
Area of Science:
- Neuroscience
- Neurology
- Epileptology
Background:
- Epilepsy can affect brain lateralization of functions like speech.
- Left-hemisphere dominance for speech is typical, but exceptions exist.
Purpose of the Study:
- To investigate verbal abilities in patients with left-hemisphere epilepsy and speech areas in the right hemisphere.
Main Methods:
- Comparative analysis of verbal skills.
- Assessment of patients with epilepsy and atypical speech localization.
Main Results:
- Patients with left-hemisphere epilepsy and right-hemisphere speech showed verbal abilities comparable to patients with right-hemisphere epilepsy.
- These patients differed significantly from those with left-hemisphere epilepsy and typical speech localization.
Conclusions:
- Speech lateralization, not just epilepsy hemisphere, is crucial for verbal ability.
- Findings suggest plasticity and compensatory mechanisms in epilepsy affecting language.

Higher Mental Functions of the Brain: Language
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...
