Lobe
TweetA major subdivision of cerebral cortex. Most classifications recognize four lobes: occipital, parietal, temporal, and frontal; but the insula is sometimes described as a fifth lobe. There are two of each lobe: one in the left hemisphere and the other one in the right hemisphere.
Lewy Body Disease (LBD)
TweetA degenerative brain disorder characterized by gradually worsening cognitive impairment. LBD is a less prevalent type of dementia than Alzheimer’s Disease (AD) and is characterized by a somewhat earlier onset. Unlike AD, it is not dominated by memory impairment and other aspects of cognition may be as or more impaired.
Left Cerebral Hemisphere
TweetThis hemisphere is mostly in charge of language and of “crystallized” cognitive skills. It receives sensory information from the right half of the sensory fields and controls the right side of the body.
Lateralization
TweetFunctional specialization as it relates to the two hemispheres of the brain. If certain cognitive, sensory or motor functions are controlled by a particular hemisphere (left or right) then that function is lateralized in that hemisphere
Language Dominant Hemisphere
TweetThe cerebral hemisphere which controls most of the language functions (the left hemisphere in most people).
Language
TweetLanguage is an extremely versatile cognitive tool enabling us to represent various aspects of the world to formulate thought in a symbolic form and communicate complex ideas. Language is both a major accomplishment and a major driving force of human culture. Language is supported mostly by the cerebral cortex. In most adult individuals the left cerebral hemisphere is […]
