Brain Structures and Functions Worksheet
Provide a brief description for each of the following functions:
1. Basal ganglia
Controls cognition and movement coordination as well as voluntary movement. It is also a component of the corpus striatum and it consists of the subthalamic nucleus and the substantial nigra (About.com, 2012).
2. Corpus collosum
There is a thick band of nerve fibers and these are called the corpus collosum. This is what divides the cerebrum into two hemispheres, a left and a right. It creates communication between the left and the right sides by connecting them. It also transfers motor functions, sensory, and cognitive information between the two hemispheres (About.com, 2012).
3. Temporal lobe
The temporal lobe has three general function areas. These are the superior temporal gyrus, the inferior temporal cortex, and the medial temporal cortex. The superior temporal gyrus I where our hearing and language come in. The inferior temporal cortex helps us identify complex visual patterns. The medial temporal cortex is what we rely on for memory (Pinel, 2009).
4. Occipital lobe
This is what is used to help us analyze the visual input which guides our behavior. Without it we may act differently than what we currently act because we wouldn’t see things the same way (Pinel, 2009).
5. Frontal lobe
Each frontal lobe has two very unique functional areas which are the precentral gyrus and the frontal cortex which is right beside it which have motor capabilities. Frontal lobes are also one of the four main regions of the cerebral cortex. This is where all your planning and decision making goes on and how you solve problems (About.com, 2012).
Cerebrum means cerebral hemispheres. When comparing the cerebrum to the brain stem it is known to be more complex and have an adaptive process such as your...
