Amygdala

Sleep deprivation is a serious issue in America. According to the National Sleep Foundation, about 45% of Americans report daily difficulties as a result of their sleep deprivation, and about 30% reported sleeping six or fewer hours a day. Though, sleep deprivation is a big concern in the United States due to its cognitive and learning impairments, the effects of sleep deprivation in mood and emotions is not. That said, in this paper, we will discuss how sleep deprivation can affect emotional…

threatening and dangerous situations. humans initially learned to have three sources of fear: germs and diseases, physical threats, and sources of poison (Minnesota M.U). The Amygdala is a gland in the brain that helps detect and create the human fear response. When a threatening stimulus is encountered the Amygdala sends messages that put a person in a state of vigilance and attentiveness. This reaction prepares someone to defend them self. Scientists often refer to this as “fight or…

1. Connect the concepts presented in the video to course concepts. After watching the video episode of The Secret Life of the Brain, the course concept that comes to mind are the Frontal lobe (Prefrontal cortex) of the brain and the amygdala. First, when watching the video episode, the episode discussed how the frontal lobe entitles how the brain helps humans to engage with each other and our environment. However, the frontal lobe becomes a contributing factor of how the psychological disorder…

There are four different areas that control our brains and the way we think about brains. The four regions are the Amygdala Prefrontal cortex (PFC), Anterior cingulate cortex (ACC) and the Hippocampus. The impulses and signals sent throughout the…

children and those brain scans concluded that “poverty also appears to alter the physical makeup of a child's brain; those children exposed to poverty at an early age had smaller volumes of white and cortical gray matter, as well as hippocampal and amygdala volumes.” (Bidwell 1). Gray matter processes information and the hippocampus stores long-term memory, while white matter connects the gray…

that animals have a special place in the human heart. But how do they affect the brain? A team of researchers at Caltech found individual brain cells that react to animals but not to other humans, places or things. These cells were found in the amygdala, an area of the brain that is involved with emotions. These cells react to any kind of animal, such as dogs, cats and even spiders. It is said that one reason modern day humans have these cells could be that animals posed a threat to our…

of the brain affected by ASPD is the amygdala (Hancock, 2014, p. 149). The amygdala is located just between the ear and the eye on both sides of the head. This is the part of the brain that processes fear, as well as what causes a person to decide their aggression level. All senses that a person has communicate with the amygdala, so a lot of emotional processes interact with it, and it also decides what motivates a person to act in certain ways. The amygdala in someone who has been diagnosed…

Cognitive psychology is the study of human mental processes that occur within the mind. It looks at such internal processes such as, memory, perception and attention. It came about in the 1950’s as a result of the behaviourist approach being flawed; internal mental processes cannot be observed. Therefore, from this an alternative method of looking at the physiological side of the brain had to emerge. Cognitive neuroscience was then born to identify the neural mechanisms, which are responsible…

temperature. Before I could go eat, I had to take my entrance exam to be a student in the Scripps Howard School of Journalism and Communications. Moments before I took the exam, I started to feel a little anxious. Anxiety is controlled by the Amygdala, the amygdala is responsible for major emotions, in particular fear. After eating, I went back to my room to finish my University 101 homework, the part of the brain that gave me ability to remember the information needed to do my homework was the…

Introduction There are few things that are universally shared between all members of the human species – one of the most prominent being our emotions and feelings. Studies have focused on this broad topic of emotion from an evolutionary perspective – suggesting that certain primal instincts such as fear or disgust are innate. Our bodily response to them functions as a way to increase or decrease our responsiveness to the stimuli. For example, fear is associated with widened eyes and flared…
