Every individual has many incidents stored in his memory. Memory played an extremely important part of the development of human society. Memory improvement techniques are pretty simple to learn but they require a lot of practice and constant use, otherwise there is hardly any benefits.

Neurons in nervous system


Neurons, the basic blocks of the brain and nervous system. They are excitable cells: that is, they transmit electric impulses along the fibers that connect them.

It is possible that the time at which a neuron transmit also carries information.

These impulses are every fast, reaching over 500 kilometers per hour. This means that, over the very short distances between cells, such impulses take only milliseconds. A neuron also is an element that can distinguished the inputs it receives into two cases, those leading to transmit and those that do not.

The details of connections among of neurons are guided by experience and learning. Experience fine tunes the organization of connections among neurons in the brain. This termed as synapse.

Researchers observed that memories aren’t stored in a single location, memory bank, but rather are widely distributed in different networks of neurons throughout the brain.

Most of these networks reside in the cerebral cortex, which is the outer layer of the brains two hemisphere and the most highly developed part of the human nervous system.

Researchers found that the brain remembers by ‘walking through’ massively interconnected groups of concepts that are stored throughout the brain.

Synapses are constantly strengthened or weakened and new dendrites are growing to link neurons together in new patterns. This continuous process of brain reorganization underlies all long term memory and learning.

Every times the person store something in long term memory, the connection strength of existing synapses is changed or new synapses are grown.

The connection between the neurons are much stronger than the fluctuations in the brain.
