Long-term depression

brain is that of a computer. New bits of information are written in a particular location, and stored in the hard drive. For a better example, encoding of a memory is like hitting save on a computer file. Once the file is saved, it can be retrieved as long as the hard drive remains…

disease (Boeree, 2009). The α-7 nicotinic acetylcholine receptors (α7- nAChRs) are highly expressed in the hippocampus (Prickaerts et al., 2011). Hippocampal long-term potentiation (LTP) is the constant increase in the efficiency of synaptic transmission. Research supports the hypothesis that α-7 nAChR agonists improve LTP and the formation of long-term memory in animal models due to the activation of the MAPK signaling pathway, with phosphorylation of ERK and CREB. α-7 nAChR agonists also…

doing or seeing something, and wonder to yourself how on earth did I remember that? Well, in this paper I will try to help you get a better understanding. I will explain how things you do, see, or hear become a memory. I will also discuss long term and short term memory along with why and what makes you forget. There will also be a page about amnesia , and the different systems and types of memories. I know at first it doesn’t sound that interesting, but if you just give it a chance I promise…

An average person can remember things that happen in their lives whether it be for a short time, or a long time. There are many factors involving the memory of the brain such as sleep. The human brain is a unique and amazing place where one can store things about their life. Some would say, that the human memory is like a huge library of moments stored throughout our brains. In my opinion, this is a great process is that if we are experiencing something new in our life, we can go and look up a…

Imagine your parents are in their sixties now and are beginning to forget certain things with age. Growing up your parents have been your support system through everything. From many amazing birthdays, graduation, and even the birth of your children. Although, you find your mom Lucy forgetting things that should not be forgotten, like a close family friend’s name. After a few months of this behavior, the forgetfulness has escalated from forgetting to pay the light bill, to forgetting to wish you…

POLYCHRONIZAT ION There has been recent experimental evidence that neurons can transmit information through precisely timed spike patterns. Patterns can be found in the precise spike timings of a group of neurons, which form a functional neuron group. Polychronization [20] can be defined as the ability to produce ‘time-locked’ but not synchronous firing patterns with milli-second precision. A network consisting of a group of neurons recurrently connected, with axonal delays and a synaptic…

sleep, long term memory, dream theories, flashbulb memories and interference, to name a few. The way that some of these topics are portrayed in the movie are correct, and actually give an accurate, but comedic interpretation of how the memory works. Although the movie has some moments where concepts that involve memory are not necessarily correct, overall it gives a relatively accurate display of how information is processed in people’s minds. To start, the movie mainly focuses on short-term…

There are three types of memory: sensory memory, short-term memory and long-term memory and all of them have a different role. Mastin (2010b) summarised that the sensory memory is the shortest term stores sensory information which received through the five senses of sight, hearing, smell, taste and touch but only for an instant. For example, the image of a person on the screen…

into a form that can be expressed and retained in memory. The second process is storage and is how information is retained so that it can be used at a later time. These two processes take part in converting information from the short-term memory (STM) into the long-term memory (LTM). Both of these are aided by rehearsal which is whereby something is consciously done to retain information in memory. The third is retrieval which is the process of locating and recovering information from the LTM to…

changed the individual’s ability to function in society. Alzheimer’s disease is also important in the field of memory because an individual’s ability to learn and repeat functions is based on memory that is encoded, stored and placed to our short-term and long-term memory. With this disease, the ability for one to function slowly disintegrates due to the memories of a specific function of ability…
