The cerebellum is the primary center for the integration and control of patterned,
In humans, the highest level of control is localized in the cerebrum. Localized at
this level are conscious sensation and volitional motor activity.
The visceral level within the cerebrum is concerned with visceral activities of the
body, as related to fight-or-flight, fear, and other emotions.
The second level of the cerebrum is concerned with stereotyped patterns of
The third level of the cerebrum is the volitional level. Here, cognition (thinking)
occurs, and unique, brand-new solutions can be created. (para 12-35)
The precentral gyrus is Brodmann's area number
4 . The center for hearing is
In right-handed individuals, the left cerebral hemisphere is said to be dominant
over the right cerebral hemisphere. For most individuals, an injury to the left cerebral
Memory is the faculty which enables an individual to store and retrieve factual
items such as sensations, impressions, facts, and ideas. All sensory inputs are collated
against these stored items in order to arrive at an appropriate decision for action.
There are at least two types of memory--short-term memory and long-term
Short-term memory is usually limited to about seven bits of information.
A portion of the cerebral cortex is thought to be important in transferring
information from short-term memory to long-term memory. It is called the hippocampus.
What is the effect on learning if the hippocampus is nonfunctional? The individual can
learn nothing, but previous long-term memory remains intact. (para 12-38b)
