Question for the Flashbulb Memory articles: Explain flashbulb memories‚ and how they are similar to (or different from) normal memories. What are some of the theoretical explanations for flashbulb memories? Which explanation(s) do you find most compelling‚ and why?

SCARS THAT WON’T HEAL: THE NEUROBIOLOGY OF CHILD ABUSE By Martin H. Teicher 68 In 1994 Boston police were shocked to discover a malnourished four-year-old locked away in a filthy Roxbury apartment‚ where he lived in dreadfully squalid conditions. Worse‚ the boy’s tiny hands were found to have been horrendously burned. It emerged that his drug-abusing mother had held the child’s hands under a steaming-hot faucet to punish him for eating her boyfriend’s food‚ despite her instructions

Alprazolam (or Xanax) is a common drug prescribed to treat anxiety disorders. Anxiety is the human body’s reaction to stressful‚ threatening‚ or uncommon situations. Some individuals report feeling fear‚ agitation‚ uneasiness‚ and distress (Lee). Approximately 18% of the United States population suffers from this disorder (NIMH). The physiological processes behind anxiety must be noted to understand how Xanax treats this disorder. Anxiety will constantly cause the human body to enter a sympathetic

common in children. It is frequently developed from a mixture of genetic anxiety‚ post-traumatic stress disorder‚ and physical issues in the brain. Amygdala is a part of the brain that controls a human’s fight or flight response‚ but in people with selective mutism‚ the amygdala is damaged. When introduced to speaking with another person‚ the amygdala sends the brain a signal that it is dangerous to speak (Selective Mutism Foundation). People with this disorder understand spoken language perfectly

they also exhibited enhanced anxiety-like behaviour in elevated plus maze (EPM) and open field. Depressed rats showed impaired spatial learning in the rewarded alternation task. They also showed differential morphological changes in hippocampus and amygdala. We observed decline in CA1‚ hilar region and dentate gyrus (DG) volumes with basolateral amygdalar hypertrophy (BLA). Interestingly‚ chronic treatment with NAC restored the depression-induced behavioural and cognitive deficits. We also found that

Within the brain‚ the main structures that determine mood and behavior are the amygdala‚ the thalamus‚ and the hippocampus. The amygdala is associated with emotions such as anger‚ pleasure‚ sorrow‚ fear‚ and sexual arousal. The thalamus is the region of the brain responsible for speech‚ behavior and movement. The hippocampus helps internalize certain events and creates long-term memory. Recent evidence identifies certain alterations in these areas of the brain in people suffering from depression

Advances in brain imaging technology (BIT’s) enable us to investigate the relationship between biological factors and human behaviours in greater depth. BIT’s are used to move away from more invasive techniques of studying the brain‚ such as liasoning - intentional scarring of the brain‚ and ablation - intentionally cutting out pieces of the brain. The brain imaging technologies that will be examined are electroencephalography (EEP)‚ functional magnetic resonance imaging (fMRI)‚ magnetic resonance

How Does Fear Affect The Brain? There is no doubt that the brain is the most vital organ in our bodies. Ever since humans have been given the opportunity to study the brain‚ so much has been learned and understood to better the future of humanity. Many advancements are still being discovered to this day and will continue to broaden the future of neuroscience. In the brain emotions play a big role in our behavior‚ but fear seems to be the most unpleasant of all the emotions. What causes

Also‚ patients with SAD have been found to have a hypersensitive amygdala. In response to anxiety-inducing stimuli‚ increased amygdala activation was shown. The amygdala controls fear cognition‚ and the hyperactivation can cause people to overestimate social threats. Patients were also found to have an enlarged hippocampus depending on the different situations‚ and

toxic. Repeated exposure to stressful situations during childhood can cause the developing limbic system to release stress-mediated hormones and neurotransmitters effecting development of stress sensitive areas of the brain including the hippocampus‚ amygdala‚ neocortex‚ cerebellum‚ and white matter tracts. Stress response systems can also be affected‚ possibly altering the way the body response to stressful situations through processes such as neurogenesis‚ a process of synaptic overproduction and pruning
