What Causes Short Term Memory And Long Term Memory Loss?Memory loss or amnesia is an uncommon forgetfulness that can happen due to brain damage. Illness, injury or extreme mental distress can be the causes of this brain damage. Memory loss can be grouped using many criteria. Loss of memory can be classified into permanent and temporary memory loss on the basis of the time span of the memory loss. Memory loss is also sorted into short-term memory loss or long-term memory loss depending on the nature of the memory that gets affected. Memory loss can occur almost suddenly and can also take shape over a long period of time. What causes memory loss? All of them are caused due to specific reasons. Long-term memory (LTM) is memory that is stored as meaning. It may remain for ages. It may also be very short lived, say, for only 30 seconds. Long-term memory (LTM) is functionally and structurally different from working memory or short-term memory. Working memory or short-term memory apparently retains information for only 30 seconds or so. Biologically, short-term memory is a short-lived potentiation of neural connections. By meaningfully correlating them and through rehearsals, short-term memory can become long-term memory. It is thought that by the long lasting enhancement of the neural connections short-term memories are stored as LTM. The structure of neurons undergoes a physical change due to this. But the time required at each step of this memory processing is still being studied. Tarnow's theory says that long-term memories are retained in dream format. This is similar to the discoveries of Penfield & Rasmussen which says that electrical excitations of cortex result in experiences resembling dreams. It is important to find out what short-term memory is. Scientists are investigating the brain and its functioning. We are getting to know how the brain processes and stores memory. We are also learning about ways to enhance these processes. So what is short-term memory? The memory function in the brain which acutely stores and processes events, images, data is known as short-term memory. It is a kind of place for storage in our brain so that it can be decided whether these memories are to be used promptly and/or reserve them to long -term storage. Short-term memory functions as a filter as well as a workplace for the things we are processing. It is much easier to access and utilize information from short-term memory than long-term memory. What causes short-term memory and long term memory loss? • Ageing In these cases support from family members should be made available. The patient must be familiarized with reality by providing familiar music, objects, or photos. Some cases might need assistance for relearning. Medication schedules should be written down so that there is no burden on memorizing. Extensive amenities for care and treatment like nursing homes are a worthwhile consideration. They are more needed for patients whose basic needs cannot be dealt in any other way and whose safety and nutrition are at a risk. What causes short-term memory loss after naps? The rates of sensing of all the sensors are brought down while
sleeping. The stimulation margins are increased at this time. This
allows the process of transferring information to continue without
any disturbance. Only if some danger occurs or a threat signal is
received this process might be interrupted. Thus information from
the sensors/surroundings is not received at this time. This allows
the working memory to perform the transfer of data. It is similar
to a sort of housekeeping. The working memory redeems information
from the temporary memory. Then it compares this redeemed
information with similar files stored earlier in the long-term
memory. If any undesirable, duplicate or overlapping data is found
it is deleted. The data that is considered to be relevant, new or
updated is encoded and put into long-term memory. The temporary
memory stays in a state of only retrieving information at this
time. Hence any brain activities like dreams are not imprinted on
to the tempora! Related
And here is another random article you might be interested in... How to be a Great SpeakerDid you know that great speakers are often nervous with butterflies in their stomach before giving a presentation? And there are many actors/actresses who can not speak to live audiences without cue cards. My 13 years as a professional speakers bureau owner allowed me to hear several thousand speakers give their presentations. Here are a few tips I learned from them. 1. You want to be nervous. Get your butterflies to fly in formation. Some tension brings about a great speech. You usually don't look as nervous as you feel. Be prepared, be relaxed. Practice, practice, practice. Use visualization techniques. One speaker suggests that you curl your toes and get rid of your adrenalin. Get out of your head and in to your heart. Reduce nervousness with self talk. Your mantra might be - "I am a relaxed, confident speaker." 2. Great presentations are well organized. Opening â€" You have 60seconds to get their attention. So start with a great question, quote or short story. Tell 'em what you will tell them. Body â€" Tell 'em. This is where you tell your 3-4 points supported by your stories. Closing â€"Tell 'em what you told them. Give them a call to action. What is one idea they can use immediately? in seven days? in one month? There are basically two kinds of presentations â€" Informative (to know) Persuasive (to do) Be sure you know what you want your audience to do as a result of your presentation. Ask. . . What do they need to know to do this? What do they need to feel to do this? Then provide 3-4 points in the body of your message and provide transitions between the points. 3. Great speeches have great stories. Sprinkle them throughout your presentation. We delineate our thoughts visually and your audience needs to "see" what they "hear." 4. Technology is just a tool. Do not be a master of ceremonies to your PowerPoint. It is not the presentation. Here are some guidelines to follow: Necessity - is this visual aid going to enhance the audience's understanding Clarity â€" to help people understand Simplicity â€" PowerPoint with words â€" no more than five words per line and five lines per slide. Color â€" color enhances the slide â€" but only use a few (we're not talking about your kid's 300 Crayola box of crayons) Visibility â€" keep it large and clear 5. Your voice is the source of power. FDR, Martin Luther King, Churchill used the power of their voice. Remember people need to see what they hear. Slow down, add a pause, whisper . . .use your voice to change tones, be loud or soft as needed. 6. Use your eyes â€" to make contact with audience. Focus on one person at a time and all the other people will feel as if you are talking to them also. This will help you to connect with people and make them feel you are there for them. 7. Interact â€" provide your audience with short role plays or partnering exercises. This gives them an opportunity to practice what you are telling them to do. Give them an opportunity to tell someone about their challenge and get some feedback as to how to resolve it. Then they can walk out the door at the end of the program ready to think or act differently. This is what every great speaker wants! 8.
