· The brain is the most complex organ in the human body. It produces our every thought, action, memory, feeling and experience of the world. This jelly-like mass of tissue, weighing in at around Brains are the reason humans are who they are. They control all decisions, actions, and emotions, with both large and small impacts. Brains are responsible for everything humans accomplish. Brains cause madness, genius, insanity, calamities, wars, opinions, oppression, society, and culture Brain as The Main Part of a Body. view essay example. Human Brain 2 Pages. The mind is a Body part that backings set up of the focal point of the sensory system in all vertebrate and most invertebrate creatures. The mind is situated in the skull, typically near the tactile organs for faculties, for example, vision

Evidence suggests that brain memories are not whole; rather, pieces of information stored in different areas of the brain are combined to create brain essay Matlin, This explains why recalled information is not entirely accurate.
Encoding, storage and recall of skills and facts semantic memory or experiences episodic memory involve different parts of the brain. This implies that there is a close relationship between memory processes and brain functioning. Over the years, there has been an intense debate on whether working and long-term memories are related.
While there are many similarities between the long-term memory LTM and working memory WMdistinct differences also exist between the two. One difference is that the functioning of LTM does not require the activation of WM. A study by Morgan et al. However, episodic memories, which rely on past experiences, may at some point involve the activation of the working memory Brain essay et al. Long-term memory has two distinguishing properties; 1 it has no capacity limits and 2 it lacks temporal decay associated with short-term memory Morgan et al.
In contrast, WM encompasses tasks of short-term memory that demand more attention, but are not directly associated with cognitive aptitudes, brain essay. It is a combination of different memories working together, including some components of the long-term memory, to organize information in the working memory into fewer units in brain essay to reduce the working memory load, brain essay.
Both WM and LTM are affected by the level of semantic processing or encoding in the brain. LTM is known to be affected by the qualitative depth of initial memory encoding Matlin, For example, it has been established that encoding during semantic processing results in improved long-term memory of episodic items compared to recall of visual or phonological items Morgan et al.
Similarly, since the performance of WM depends on the level brain essay processing at the encoding stage, semantic processing can lead to improved WM. Stadthagen-Gonzalez and Davis propose that memory is formed through dendrite-axonal networks, brain essay, which become more intense brain essay an increase in the number of events stored in the LTM.
Stadthagen-Gonzalez and Davis also postulate that memory storage involves different cortical areas of the brain, where the sensory experiences are processed, brain essay. The neural brain cells involved in memory formation undergo physical changes through new interconnections as cognitive and perceptual processes in the brain increase.
The synapses a vast system that connects neurons are involved in the formation of brain essay memories or neural networks. It is the neural networks that facilitate the formation of new memories. Karpicke and Roediger postulate that, brain essay a closely related activity relayed through similar synapsesa new memory is formed causing changes to the neural circuit to accommodate the new item, brain essay. Also, new neurons can be joined to the circuit, if they are correlated with previously formed neural networks Matlin, Long-term potential LTP is associated with reverberation depolarization in the post- and pre-synaptic neurons during learning.
It is induced through prolonged stimulation of synapses during learning. New memories are maintained through repetitive excitation of LTP, which increases the release of neurotransmitters that can persist for several days or even months. Evidence suggests that the amygdala and the hippocampus regions of the brain interact during the formation of verbal and visual memory Matlin, brain essay, However, the amygdala identifies and stores emotionally important information while the hippocampus creates new neural networks for cognitive material.
It is through the amygdala-hippocampus interaction that emotionally important memories are recalled. The same applies for less emotionally significant events, brain essay, which are less arousing. Thus, brain essay, personal and emotional experiences are easily recalled than neutral events.
It also explains why reinforcements improve memory while damage to hippocampus and amygdala results to impaired memory functioning. From an evolutionary standpoint, brain essay, the neural relationship between the hippocampus and the amygdala is an adaptive response to life experiences, brain essay. Karpicke and Roediger suggest that stressful conditions affect the processing and storage of new memories, brain essay. Also, the retrieval strategies of the hippocampus may be repressed under stressful conditions.
Consequently, it becomes adaptive to remember relevant and emotional memories for survival purposes. Also, through amygdala-hippocampus interaction, it becomes adaptive to forget or repress some traumatic or unpleasant memories in order to maintain normal cognitive functioning. Studies have shown that human recollections are often not accurate. This raises questions regarding the extent of accuracy of the memory.
Unsworth and Engle demonstrate that the hippocampus-amygdala interaction is essential in memory encoding and retrieval, with the amygdala regulating information encoding, storage and recall from the hippocampus. Thus, for some time, the recall accuracy of brain essay arousing events brain essay high brain essay to neutral ones.
Evidence also suggests that physiological changes in the level of brain essay affect the way memories are replayed. For instance, Unsworth and Engle show that, at the encoding stage, the level of activation of amygdala influence memory retention while its damage impairs memory arousal.
This highlights the fact that emotional arousal enhances memory accuracy, at least in the short-term. Memory impairment or loss may have a number of causes, including neurological diseases, aging, trauma, brain essay, stroke, or brain injury.
Individuals suffering from poor memory, amnesia and PSTD can benefit from memory aids that enhance their memory. Prospective memory PM aids can help such people to recall essential actions in their daily lives Matlin, They are normally external aids that facilitates semantic memory or systems that allow caregivers to monitor the cognitive functioning brain essay patients with memory problems.
Developers of these systems rely on the knowledge regarding the functioning of the brain and memory encoding processes to make memory aids, brain essay.
Also, understanding the type of memory affected can help in the treatment of the individual through psychoanalysis. Age and environment influence several cognitive and physical abilities in humans. Elderly people often experience difficulties in performing high cognition-demanding tasks because aging impairs memory processes such as working memory, brain essay, encoding and sensory functioning, brain essay.
This leads to a decline in memory, reasoning and problem-solving ability. However, automatic processes that do not involve much cognitive resources remain unimpaired during old age, brain essay. Karpicke and Roediger suggest that old age does not significantly affect memory processes as attention-demanding tasks may, with time, become automatic. Environmental conditions also influence the development and maintenance of memory. The environment affects memory through neural mechanisms. Environmental enrichment through memory-based tasks and physical activities increase hippocampus volume by promoting cell neuron proliferation Matlin, Also, problems associated with social environment such as stress affect memory brain essay brain functioning in humans.
