Cerebral Cortex: imagine a Texas cowboy hat on top of a brain. The cortex is the outer layer of the brain just under the hat where complex thinking occurs.

* Corpus Callosum: The corpus callosum is the fibers that connect the two halves of the brain. Thus, it adds the two parts together. Think of the corPLUS CalloSUM. Since the corpus callosum coordinates communication between the two hemispheres, think of corpus Call Someone. * Thalamus: the thalamus takes sensations that come from the body and directs them to the appropriate part of the brain for processing. Thus, think of Hal and Amos - two traffic cops in the brain who direct these sensations to the right route. * Hypothalamus: the hypothalamus regulates a number of things in the body such as body temperature, thirst, hunger, and sex drive. Think of “hypo the llamas”. Your llamas are hot, sweaty and thirsty and you use a hypo to spray water on them to cool them down and give them some water. * Hippocampus: the hippocampus is the seat of memory. Think of a hippo with a compass. The hippo uses the compass to find his way back to the swamp because he can’t remember where it is. * Amygdala: the amygdala controls your sense of fear. Think of either a MIG coming right at you and, of course, making you afraid, or picture a scary wig with dollars in it * Pons: the pons helps you relax and sleep. Think of a relaxing pond. * Cerebellum: the cerebellum helps in coordination and balance. Picture your favorite athlete with bells all over his/her body (hanging from his/her clothes, hands, feet, etc.). * Reticular Formation: the reticular formation helps you to become alert and aroused when you need to be. Think of what would happen if you were napping and someone tickled you: your reticular formation would kick into gear to wake you up.

* Medulla: the medulla regulates the autonomic activity of your heart and lungs. Picture medals over your heart and lungs, or stick those medals into a heart.

Reticular Formation

There were three main parts of the brain: the forebrain, midbrain, and hindbrain. this was talked about in chapter 2, Mastering the World of Psychology. One of those parts is called, Hindbrain, which is the lowest part of the brain. Inside the Hindbrain it has Medulla Oblongata, Cerebellum, Pons, and the Base of Reticular Formation. The Medulla Oblongata controls the breathing, digestion, heartbeats, swallowing and coughing but scientists also say that we would not be able to live without a Medulla…

including the anterior nucleus and possibly the dorsomedial nucleus. One way in which the limbic system has been conceptualized is as the "feeling and reacting brain" that is interposed between the "thinking brain" and the output mechanisms of the nervous system. In this construct, the limbic system is usually under control of the "thinking brain" but obviously can react on its own. Additionally, the limbic system has its input and processing side (the limbic cortex, amygdala and hippocampus) and an…

The Limbic System

The brain is the ultimate meaning of life over death. Your heart can still be beating, but if you do not have brain activity you are not experiencing any of the pleasures or even the dullness of everyday life. The brainstem, limbic system, and the cerebral cortex are the most important structures within the brain. The brainstem provides the ability for a person to survive from moment to moment through the breathing process and maintaining the consciousness. The structures of the brain stem are the…

Peripheral Nervous System

A. THE NERVOUS SYSTEM 1. What are the central and peripheral nervous systems? What structures are part of each? The central nervous system includes the brain and the spinal cord. This part of the nervous system controls the activity of the nervous system by sensory impulses being transmitted to carry out actions; basically the body’s command system or the boss of the human body. The peripheral nervous system is where the actions are actually carried out. This system contains the nerves. To be more…

The Brain The human brain is made up of four specific lobes. They are called the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The cerebral cortex is considered our “old brain” because its evolution can be dated back almost 500 million years, and the cerebral cortex is considered our “new brain” (Feldman, R. S., 2010). The central core and the cerebral cortex are extremely important. They control body and mental functions that are crucial for our quality of life. In the central…
