How are the right and left cerebral hemispheres specialized for different functions quizlet?
The cerebrum is divided into two major parts: the right and left cerebral hemispheres or halves at a fissure, the deep groove down the middle. The hemispheres communicate with each other through the corpus callosum which is a bundle of fibers between the hemispheres. Each hemisphere controls muscles and glands on the opposite side of the body (i.e. the right side of the brain or hemisphere controls the left side of the body.)

Most sensory information is routed to the cerebral cortex via the thalamus. Olfactory information, however, passes through the olfactory bulb to the olfactory cortex or piriform cortex. The vast majority of connections are from one area of the cortex to another rather than to subcortical areas. Cortical regions known as associative cortex are responsible for integrating multiple inputs, processing the information, and carrying out complex responses. The cortex is commonly described as comprising three parts: Sensory Areas, Motor Areas, and Association Areas. Sensory Areas are the areas that receive and process information from the senses. The parts of the cortex that receive sensory inputs from the thalamus are called primary sensory areas. The senses of vision, audition, and touch are served respectively by the primary visual cortex, primary auditory cortex and primary somatosensory cortex. In general, the two hemispheres receive information from the opposite (contralateral) side of the body. Motor Areas are located in both hemispheres of the cortex. They are shaped like a pair of headphones stretching from ear to ear. The motor areas are very closely related to the control of voluntary movements, especially fine fragmented movements performed by the hand. The right half of the motor area controls the left side of the body, and vice versa. Two areas of the cortex are commonly referred to as primary motor cortex, which executes voluntary movements, and supplementary motor areas and premotor cortex, which select voluntary movements. Association Areas function to produce a meaningful perceptual experience of the world, enable us to interact effectively, and support abstract thinking and language. The parietal, temporal, and occipital lobes - all located in the posterior part of the cortex - organize sensory information into a coherent perceptual model of our environment centered on our body image. The frontal lobe or prefrontal association complex is involved in planning actions and movement, as well as abstract thought. Our language abilities are localized to the association areas of the parietal-temporal-occipital complex, typically in the left hemisphere. Wernicke's area relates to understanding language while Broca's area relates to its use. A longitudinal fissure or division separates the brain into two distinct cerebral hemispheres, connected by the corpus callosum. The sides resemble each other and each hemisphere's structure is generally mirrored by the other side. Yet despite the strong similarities, the functions of each cortical hemisphere are

The split brain further suggests that each hemisphere is a complete cognitive system.
How do the two hemispheres of the brain function quizlet?The brain is divided into two hemispheres, called the left and right hemispheres. Each hemisphere provides a different set of functions, behaviors, and controls. The right hemisphere is often called the creative side of the brain, while the left hemisphere is the logical or analytical side of the brain.
Does our right and left brain specialize quizlet?Terms in this set (5)
Some brain functions involve a higher degree of activation on one hemisphere of the brain than the other. Although the left and right hemispheres are specialized for some tasks, they still work together in an integrated fashion.
Which of the following distinguishes the right and left cerebral hemisphere from each other quizlet?Which of the following distinguishes the right and left cerebral hemispheres from each other? The right hemisphere is responsible for visual, emotional, and artistic awareness, whereas the left hemisphere is responsible for language and calculation.
