Human Memory


Definition: Memory is our ability to receive and translate information, store or retain that information and then bring back that information and other past experiences in the human brain. You may also think in a more general term that it is the use of one’s past experiences to affect or influence one’s current behavior. Memory is also the total of what individuals remember and thus gives us the capability to learn and to also adapt from our previous experiences as well as to help build relationships. It has the powerful capability to recall to our mind past experiences, previously learned facts, skills and habits.

In a more physiological or neurological term, memory is, a set of encoded neural connections in our brain. With the synchronous firing of neurons that had been involved in our original experience, we can reconstruct or recreate past experiences. However, our memories are not stored in our brains like books stored on a library shelf, they are more all over and so in the recalling of any memory it comes together based on an on-the-fly reconstruction. In the human memory we have the sensory memory, the short-term memory and the long-term memory.

Computer Memory


Definition: A Computer memory is any physical device that can store information temporarily or permanently. You have Random Access Memory (RAM), which is a volatile memory that stores information on an integrated circuit used by the operating system, software, and hardware. You also have hard drive which stores long term information that will be needed after the power to the computer has been turned off.


Similarities of Human Memory & The Computer

RAM vs Memory

One would wonder if the human brain is what was used to inspire to create the computer memory as the similarities between both are closer than an average person would think.

Computer memory is closely referred to RAM (Random Access Memory), this RAM memory is considered short-term as it is gone as soon as the computer is turned off. In similarity to the brain, if the information in the human short-term memory is not actively transferred to the long-term memory it disappears after it is replaced by another memory. Our short-term memory is in the brain region
called hippocampus.


The hippocampus that controls the short-term memory is where our immediate actions are remembered. Just like the computer memory that has a limit so does the human memory as we may remember up to certain time-period of our lives although for some persons their memory range enables them to have their childhood memories.

The image below shows the billions of cells that are compacted in the brain that helps with memory located in the hippocampus. 


 As the computer memory has arrays, the brain has a similar structure to allow the brain to recognize the memory, recall memory, and relearn the memory if needs be. 

Based on studies done the brain transfers some if not all memories to another section of the brain to turn them to long term memories and that is done while you sleep.

 

Hard Drive vs Memory


Another similarity is that just as the computer uses the hard drive to store programs that will be used daily for as long as the user sees fit, so the brain stores information and experiences in the cortex to retrieve whenever needed.

Now, in this section of the brain called Cortex, it stores memories for extended time-period (1mnth - 20+ years) otherwise called Long-Term Memory. These memories are safely tucked away by the brain for future recall, this process of the recall is done by the hippocampus.

Data Base vs Memory

In drawing parallels between our human brain and a computer database you come up with a variety of other similarities. Both the brain and the data base have memory, they both use electrical signals and they can retrieve and transmit data both. The data base and the memory have partitions, and both connect data to reach to conclusions which are logical and working, for example retrieving a list of duties a human need to do and retrieving a list of workers in a data base. Being able to analyze and link scattered and proportionate data, computers, consequently, have the capabilities to create logical structures, allowing them to understand and learn.



Dissimilarities of The Computer & The Human Memory

Dissimilarity #1: Short Term Memory is not Like the Computer Random Access Memory (RAM)

According to author Chris Chatham from science blogs online forum, he describes short term memory as being a ‘pointer’ or storage location for other long term memory that already exist, whereas with the computer, RAM is a similarity of the data that is stored on the computer’s hard drive, except the data goes once power is removed from the computer. Additionally, he iterates that unlike RAM, short term memory does not have a fixed size, but rather varies according to factors that are not limited to but include: expertise and familiarity.


Dissimilarity #2: Unlike computers, processing and memory are handled by the same components of the human brain

Chatam states in his article that the computer processes its task from memory using the central processing unit (CPU) and then sends that information back to memory either for storage or to be outputted whereas in the human brain, the information that is being processed or retrieved from memory is also being modified in the same occurrence. This is why, for instance we may recall a memory from the past based on a trigger or cue, but less accurately than it initially occurred.

Dissimilarity #3: CPU Cache and neuronal network attractors

The computers CPU is essentially a device that combines bits of information and operates at very high frequencies, in the GHz range. Since the CPU processing speed was so fast, cache was developed to assist in storing these extra bits of data until the cpu was available for processing again. Unlike the CPU our memory operates at around 10-40 Hz, which is far less than the CPU.
