Limbic system

1) The Amygdala - It is in charge for the ability to read someone else’s face for clues to how they are feeling. The amygdala is located in the limbic system and is the integrative center for emotions, emotional behavior, and motivation. Both the amygdala and the hippocampus help humans remember meaningful experiences. Other findings provide direct evidence that the amygdala is engaged in processing the emotional convexity of faces with a specificity of response to fearful facial expressions…

Grief. Complicated grief is prolonged grief, which can affect more than the emotional part of your brain. With complicated grief, any memory of the lossed one can cause grief, but also pleasure. The nucleus accumbens, which is in charge of the reward system and social attachment, is affected in complicated grief. Because of that, grief can be pleasurable. By making grief a pleasure, it's now harder for individuals with complicated grief to move on and get their mental health back because they…

mouth. Human have 5 different types of receptor cells that responds to five primary taste: salty, sweet, sour, bitter, and umami. Human are able to interacts with the world through the peripheral nervous systems which uses nerves to connect the body’s sensory organ to the central nervous system. The receptors of taste are found on specialized taste receptor cells. These cells are on the 2,000 to 10,000 taste buds that a normal human has. Two third of the taste buds are located on the tongue…

The respiratory system is responsible for the balance of oxygen and carbon dioxide in the body to meet metabolic demands. The way a person’s breathe can be affected is by emotions and/or changes in the internal environment. The breathing process is mainly controlled by the brainstem and peripheral system. The brainstem controls several important functions of the body like arousal, breathing, and blood pressure, among other functions. In the brainstem, the medullary respiratory center consists of…

addiction has an immense effect on one’s brain and behavior which causes numerous negative modifications. Addiction modifies emotional, cognitive and social behaviors (Smith 2). The brain’s reward system, in particular, plays a significant role in these changes. The mesocorticolimbic dopamine reward system is used to stimulate adaptive behavior (Durrant, et al 1051). Three main factors of reward are the conscious and/or unconscious experience of pleasure in response to a rewarding stimulus,…

To my luck, I had many resources conveniently available and at my reach. Some of these resources included newspapers, magazines, books, and one of the greatest tools available to our generation: the Internet. The Internet is a global communication system that links computers worldwide, enabling them to exchange…

The limbic system is divided into four sections, the hippocampus, the amygdala, the hypothalamus, and the thalamus. The hippocampus is in charge of turning your short-termed memories into long termed memories. As MDhealth.com informs us, “The hippocampus also helps…

Undergoing an amputation generates sufficient trauma in and of itself, adding to the shock is the experience of excruciating pain caused by a limb or other body part that is no longer attached to the body, this disturbance can prove to be not only exasperating but extraordinarily frightening as well. This strange phenomenon, of experiencing a limb that has been removed from the body, is referred to as a “phantom limb.” Around “90 percent of amputees worldwide” have experienced these puzzling…

When we feel an emotion it is simply a chemical reaction in the brain,and our most basic emotions occur in the limbic system. The limbic system is one of the less evolved system of our brains that came after the development of the “old brain”. This small portion of your brain is vital in perception of emotions. The Hippocampus, Thalamus and Amygdala are two parts of this system whose main purpose is to control emotion. The hippocampus is in charge of memories, and how we perceive them , the…

Neurologic and retinal diseases There are many different types of degenerative neurological diseases. The brain is a complex system and this makes the use of stem cells difficult to differentiate to the right cell type. The myriad connection between nerve cells and the complex interdependency with macroglia, which is made up of astrocytes, oligodendrocytes, and glial progenitor cells create a problem with creating precise structural reconstitution with stem cells. Neurological diseases including…
