Human Brain and Memory - How They Come Together

As you can imagine memory functions of the brain are extremely complex. To date, scientists have been unable to design computers that can effectively compete against a human brain. Their continued research into this continues and shows promising signs that in the next twenty or thirty years that scientists may be able to devise advanced computers with the assistance of developing nanotechnology, cybernetics and biotech resources.
Scientists and researchers have put a great deal of effort into trying to discover and learn about all the elements of the human brain memory system so as to get a better understanding of all of it’s encoding and retrieving processes. The uncovering of these mysteries are vitally important in improving the quality of an individual’s memory and recollection process.
Human Brain Structure and Memory System
Our thoughts, senses, memory and actions all work to influence distinct sets of nerve cells and chemicals within our brain’s structure. The hippocampus, the amygdale and close areas of temporal lobe interact with the cortex with the help of complex nerve cells. This actually forms the fundamental structure of the human brain memory system.
When a nerve cell in the brain is activated, a low-charged electrical potential is sent to the axon. This helps to release chemicals or neurotransmitters into the brain, which effectively bridge the synaptic gaps between nerve cells and bolt onto the corresponding receptors. The nerve cells that receive the influx of the brain chemicals then send the signal along to other relevant nerve cells. This can be compared to what happens in a relay race.
When similar signals are received repeatedly, the synaptic changes occur more efficiently contributing to the physical changes among synaptic connections. This is how the human brain stores its memory on a long term basis. Scientists and researchers believe that the changes in particular synaptic patterns in folds and ridges of human brain contribute to memory encoding for lengthy time frames.
Research on Human Brain and Memory
There are debates on how the distribution of memory occurs in a human’s brain. Many scientists are of the opinion that the human brain constitutes memory in a particular region within the brain structure, while others claim that the human brain does not localize memory within a particular territory, and have the belief that memory is in fact distributed through out the brain structure.
Scientists claim that the cell functions corresponding to learning and memory process are indistinguishable at the biological level. Proof in support of a strong correlation between learning process and memory system has been already established. It is also been discovered that in order to execute the learning process, the human brain employs multiple memory systems, each of designed to encode different sorts of memory functions.

hi,
There has always been debate on the distribution of memory in the brain.Well there is always a corelation between the memory and the learning process.
