Hippocampus

into adulthood, Lupien, McEwen, Gunnar, and Heim (2009) delineated the effects of acute stress versus chronic stress on the brain and behavior. Acute stressors depends on the level of glucocorticoid elevations. Small increases result in enhanced hippocampus-mediated learning and memory, where larger, prolonged elevations impair hippocampal function. Chronic stress causes dendritic atrophy in the rodent’s hippocampal CA 3 pyramidal neurons. Chronic stress can inhibit neurogenesis in the dentate…

autobiographical memory but does know semantic facts related to his life, exemplifies this (Kolb & Whishaw, 2015, p. 487-488). Episodic memory, or autobiographical memory, is related to a person’s own life experiences (p. 486). Patients with damage to the hippocampus, part of the temporal lobe, have difficulty with daily life because they lack episodic memory and an awareness of self (p. 487). Lucy’s autobiographical memory seems to function appropriately for at least the length of the day, as…

According to dictionary.com, memory is the mental capacity of retaining facts, or of recalling or recognizing previous experiences. But memories are more than that. Memories define someone’s likes and dislikes, help recognize friends from enemies (Wilson). Memories are our own identity, all our knowledge and experience comes from them. Everyday of our life we are creating new memories. They are the base for taking decisions in a person’s life but are all those memories trustworthy? When you…

The show got multiple aspects of anterograde amnesia correct. The woman suffered a traumatic brain injury at the hands of a serial killer and displays symptoms of profound anterograde amnesia. Her working, procedural, and semantic memory systems are preserved, however, her episodic memory is left substantially impaired. “When a person has difficulty learning or remembering new information, it is called anterograde amnesia” (Seamon, 2015). The woman displayed several hallmark characteristics of…

lzheimer's is the progressive mental deterioration that can occur in middle or old age, due to generalized degeneration of the brain. There is a lot of discussion in the eldercare community these days regarding Alzheimer's. With the advancements in medical technology, people are living longer than in past generations. It seems like a lot of folks may be able to physically get around better, but have more challenges with mental health issues such as Alzheimer's. According to WebMD, the biggest…

뀀뀀l Essay Introduction Visual communication is a marvelous process that requires and uses a complex framework involving our eyes, senses and brain interpretation. An eight-week course scratches the surface of the abundant knowledge there is to be had. This essay will answer some of the behaviors in which vision works and how it affects many areas of our daily lives. 1. Provide an explanation of how our eyes take in visual information and how mind interprets, processes and remembers that data.…

QUESTIONS 1. Identify whether John is more likely to be experiencing retrograde or anterograde amnesia. It appears that john is most likely subject to anterograde amnesia as he shows signs of losing his ability to form declarative memories. “Anterograde amnesia is the inability to recall events that occur after the onset of amnesia.” (Peter Harris, 2014). (pg. 105). “Retrograde amnesia is the loss of memory for events occurring before a particular time in a person’s life, usually before the…

Literature review It is a stark reality that as people age, their cognitive abilities tend to decrease, including memory capabilities. At the present, scholars have identified three types of memory stores: sensory memory, short-term memory (STM), and long-term memory (LTM). Memory includes primarily three processes: encoding, storage, and retrieval. Additionally, in order to these processes occur favorably, attention to the information or stimuli presented is vital (Garrett, 2011; Sternberg,…

Hofman et al. (2002) believed that those who suffer, from what society calls, a mental disorder where most likely to not develop all the way in learning. From what was gathered by reading this article that in order for our memories to be able to obtain everything that we need to know we must hit the markers that occur. If someone who suffers from both a mental and a physical disorder cannot hit these markers than this will most likely lead to amnesia. This theory proves to be valid because if…

terminated, a trace of its effect remains in the brain. This trace, in turn, will influence all similar processes that occur in the future. According to this point of view, a process, which is caused by an experience, can occur only once in “pure” form; thereafter, all similar processes interact with the memory trace. The stronger the memory trace, the stronger its influence on the process; therefore, one’s conscious experience will tend to be more in accordance with the trace than with the…
