Fact or Fiction
A person's personality is connected to being right brained or left brained
Fiction - there is no evidence that a person can be "right brained" or "left brained" and the separate functions of the hemispheres are not connected to personality traits
The right and left hemispheres of the brain communicate through
nerve signals
Brain asymmetry evolved _____ and is dominant for the _____ species
Brain asymmetry evolved recently and is dominant for the primate species
Lateralization of brain functions means that ____
mental processes are divided between the hemispheres of the brain and the different hemispheres have specialized functions in cognition
The right and left hemisphere work together, not independently
Fact: in order for the brain and a person to function and perform mental tasks, both hemisphere's must work hand in hand
The name of the structure that connects the right and left cerebral hemispheres
Corpus Callosum
Brain asymmetry creates ______ functions
lateralized
The left hemisphere processes more information about
language
Left-handedness is tied to a different makeup of how a person processes information: lefties use the right hemisphere of the brain instead of the left to process language
Fiction: It is tied to unusual thickness in specific areas of the brain (post-central gyrus and inferior occipital cortex) - most of the language processing occurs in both left hemisphere for both righties and lefties
The Corpus Callosum is made up of
nerve fibers
Abnormalities in the asymmetry of the brain lead to neurological and psychiatric conditions like schizophrenia and autism spectrum disorder because
the brain cannot divide functions and processes, which leads to less comprehension, cognition and processing
The right hemisphere processes more information about
spatial awareness and emotions
The less symmetrical a person's brain is the more abnormalities in function and lateralization occur
Fiction: the opposite is true, the more symmetrical a person's brain is the more abnormalities occur
Dysfunction of the corpus callosum leads to medical issues such as seizures, strokes, and epilepsy: list three signs of dysfunction
Speech, hearing, and vision impairment, developmental delays, low coordination, and intellectual disability.
The traits linked to brain asymmetry are:
cortical thickness, surface area, and subcortical volume
The cerebral hemispheres deal with different _______
tasks
