Abstract





In this study, we will focus on the sensory, and short-term memory in order to recalibrate and retrieve memory loss by dementia patient’s


Sensory memories are momentary recordings of information in our sensory systems, memories sensory memory is very brief, different sensory memories last for different amounts of time.


Iconic memory is visual sensory memory, and it lasts for less than a second. Echoic memory is auditory sensory memory, and it lasts for less than 4 seconds. For example, Echoic memory is information that is new and useful for a short period, such as facts, names, and places.


Short term memory (also called working memory) is the recording of information that currently used. However, short term memory only lasts about twenty-seconds. The human memory span can contain at any time seven chunks (any letter, word, digit, or number) of information.


When the brain receives signals of information, the information can be repeated over and over until stored, therefore creating a "phonological loop.” However, unless a repetition of the information occurs, it will be lost.

Studies Summary





MedTech is engaged in the designing of a virtual prototype iteration of a device. It is a tiny human implant the size of a grain of rice and as thick as a piece of paper. The idea behind this design is to help dementia patient’s retrieve short-term memories.


Presently there are 50 million people worldwide that have been diagnosed, in the early stages of dementia. These people due to their dementia symptoms cannot remember facts, such as names, dates, and places.


MedTech wants to help these people recall short-term memory loss. To achieve this, MedTech is using state-of-the-art iteration mathematical modeling techniques with embedded learning algorithms, inserted into this tiny implant to trigger and recall short-term memory loss.


Brain signals weaken when some cells wear out, MedTech want to target brain cell known to be “weak link” in patients with dementia brain disorders. The so-called somatostatin-positive neurons, which are involved in coding information, are the first to fail.


The signals from these cells are too weak to be revived by surrounding neurons, which relay the information to other parts of the short-term memory.


This study would target “weak link” brain cells, so-called somatostatin-positive neurons, too strengthen their signals which are involved in coding information so they can be received by the surrounding neurons, with relay the information to other parts of the brain.
