The Limbic System: Brain Item And Left Brains Of The Brain

23.The part of the limbic system located in the center of the brain, this structure relays sensory information from the lower part of the brain to the proper areas of the cortex and PROCESSES some sensory information before sending it to its proper area and is called the thalamus.

During brain development, beginning in the womb into adulthood, all of these cells must be grouped and organized into specific networks, which create the architecture of the brain (Perry & Szalavitz, 2006). The brainstem, the diencephalon, the cortex and the limbic system are the four major parts of the brain. The brain is organized from the inside out, thus, “the lower and most central regions of the brainstem and diencephalon are the simplest” (Perry & Szalavitz, 2006, p. 21) and are also the first to form, therefore, developing first as the child grows and develops (Perry & Szalavitz, 2006). As the brain develops upward and outward, the limbic system becomes more complex and the cortex is the crowning achievement of the brain structure (Perry & Szalavitz, 2006). These four areas of the brain are organized from top to bottom and inside to outside, although these four areas are interconnected, each one controls different functions such as the brainstem controls body temperature, heart rate and blood pressure, as well as respiration. The limbic system and diencephalon control emotional responses that help to guide one’s behavior such as fear, love, joy and anger. The cortex, the top part of the brain, regulates the complex and high functions such as speech, critical thinking, and decision-making (Perry & Szalavitz, 2006). The

To coordinate with our current chapter on emotions, our class watched the film Inside Out. The story was about the emotions, Joy, Sadness, Anger, Fear, and Disgust, controlling a goofy, honest, and caring 11 year old named Riley. Inside her brain, the emotions used controls to decide the way Riley feels. The part of the brain the “control center” in Inside Out represented was the Limbic System. I know this because during in our Body and Mind unit, the part of the brain we most associated with mood and emotions was this system. It is best defined as a complex system of nerves and networks in the brain, including areas concerned with instinct and mood. The Limbic System’s main control is emotions and drives feelings, which was the main purpose of the emotions “control center.”

The limbic system (or Paleomammalian brain) is a set of brain structures including the hippocampus, amygdala, anterior thalamic nuclei, and limbic cortex, which support a variety of functions including emotion, behavior, long term memory, and olfaction.[1] The term "limbic" comes from Latin limbus, loosely translating as "border" or "belt".

The brain can be considered the most complex organ in the body and the centrepiece of the nervous system. Although the brain works as a unified whole, neuroscientists have identified areas within it that perform specific functions. This makes the brain interconnected by three different layers: the central core, the limbic system, and the cerebral cortex. All of which contain structures that regulate everyday life and psychological function.

These psychological disorders originate from different area of the brain. The brain consists of three main parts: the forebrain, midbrain, and hindbrain. The forebrain is made up of the cerebrum, thalamus, and hypothalamus (part of the limbic system). The midbrain comprises the tectum and tegmentum. The hindbrain consists of the cerebellum, pons and medulla. The midbrain, pons, and medulla in conjunction are typically called the brainstem.

2. The limbic system also includes the amygdala(Amig- Dalah) which is the part of the brain responsible for emotions. In an Article called Scientists Discover Why Dreams Are So Weird they state “During REM sleep, the men's brains showed the most activity in the limbic system, a primitive part of the brain that governs emotion. Meanwhile, little activity was seen in the frontal lobes. The frontal lobes help sort out and give meaning to information from the senses. According to the researchers, this unequal activity might explain why dreams can be so intense, yet so illogical. It may also explain why dreams do not seem strange to the dreamer while they are happening” (Scientists Discover Why Dreams Are So Weird).

* The limbic system is a loosely connected network of structures located roughly along the border between the cerebral cortex and deeper subcortical.

A part in the brain called hippocampus is very important to memory. Hippocampus is the vital key to remembering and it is also vital to emotions. It also helps you make new memories so you aren’t just remembering the past. The cerebral cortex is also very important. It helps you do things without you thinking about them. Examples of what the cerebral cortex does is breathing, how to swallow, or to catch yourself before you

In addition, the limbic system is responsible for our perception of other emotions, both positive and negative, which explains the mood altering properties of many drugs. The cerebral cortex is divided into areas that control specific functions. Different areas process information from our senses, enabling us to see, feel, hear, and taste. The front part of the cortex, the frontal cortex or forebrain, is the thinking center of the brain, it powers our ability to think, plan, solve problems, and make decisions.

This region mediates motivational behaviors, emotions states, and memory processes. The limbic system also regulates body temperature, blood pressure, and blood sugar level. The hippocampus is a part of the limbic system that plays an important role is emotions, learning, and memory. Amygdala also plays an important role in the limbic system, it helps regulates aggression, eating, drinking, and sexual behavior. Another main region in the limbic system is the hypothalamus, it monitors levels of glucose, salt, blood pressure, and hormones. The hypothalamus also helps regulate processes in the body through its connection to the central and autonomic nervous system and

These chapters Dr. Goldman talks about the interrelation of the cortex and the limbic system. The cortex is considered a part of the brain that controls rationality while the limbic system is the part of brain where your emotions come from. He shows emotional intelligence like a moderation of primitive impulses by mind. He suggests that the emotional intelligence can be taught.

III) What structures are considered part of the limbic system? This system is associated with mood and motivational behavior, but these behavioral indices can be expressed as a motor response (fear may make one flee, hunger can lead to opening the refrigerator door, etc). Outline connections you would allow a response in a limbic structure to be expressed by the motor system.

The limbic system was first recognized due to Franz Josef Gall (LeDoux, J., 1996). Franz Joseph Gall developed the idea of “phrenology” that focused on the study of the different variations of bumps on the human skull to be related to differences in behavioral and emotional functioning. The limbic system’s main function in the brain is to control emotional behaviors and certain forms of memories that are infused with emotion (amygdala). The amygdala is a part of the brain that forms the tail end of the basal ganglia within the rostral temporal lobe and is located near the hippocampus (Lambert, K.G. & Kinsley, C .H., 2005). The amygdala, as defined by the text, is an almond-shaped structure that functions as a part of the limbic system involved in regulation of emotion and sexual urges (Lambert, K.G. & Kinsley, C .H., 2005). In addition, the amygdala is comprised of a dozen or more sub regions that are not all involved in fear conditioning (LeDoux, J., 1996).

The brain is dividing into several sections, including the cerebellum, the frontal lobe, and the temporal lobe, among others. The temporal lobe exists in two parts, one on each side of the brain close to the ears. It is largely responsible for the memory system (2). On the medial surface of the temporal lobe there are three important structure that are essential for human functioning. These structures are named, in order from rostral to caudal, the olfactory cortex, the amygdala, and the hippocampus. Together these three structures are referred to as the "limbic system" (1). Their functions became understood after studying how the brain functions upon loss of each structure. For example, in 1953, a patient suffering from epilepsy underwent surgery which removed most of his medial temporal lobe (1). After the surgery, the patient was able to remember who he was and was able to carry out coherent, intelligent conversations. However, if the person with whom he was talking left the room, he would have no
