symbols, etc.) participate in a more fundamental role in encoding and preservation of information in memory. The brain relies primarily on acoustic (aka phonological) encoding for use in short-term storage and primarily semantic encoding for use in long-term storage. Other senses Tactile encoding is the processing and encoding of how something feels, normally through touch. Neurons in the primary somatosensory cortex (S1) react to vibrotactile stimuli by activating in synchronization with each series of vibrations. Odors and tastes may also lead to encode. Organizational encoding is the course of classifying information permitting to the associations amid a sequence of terms. Long-Term Potentiation Encoding is a biological event that begins with perception. All perceived and striking sensations travel to the brain's thalamus where all these sensations are combined into one single experience. The hippocampus is responsible for analyzing these inputs and ultimately deciding if they will be committed to long-term memory; these various threads of information are stored in various parts of the brain. However, the exact way in which these pieces are identified and recalled later remains unknown. Encoding is achieved using a combination of chemicals and electricity. Neurotransmitters are released when an electrical pulse crosses the synapse which serves as a connection from nerve cells to other cells. The dendrites receive these impulses with their feathery extensions. A phenomenon called long-term potentiation allows a synapse to increase strength with increasing numbers of transmitted signals between the two neurons. For that to happen, NMDA receptor, which influences the flow of information between neurons by controlling the initiation of long-term potentiation in most hippocampal pathways, need to come to the play. For these NMDA receptors to be activated, there must be two conditions. Firstly, glutamate has to be released and bound to the NMDA receptor site on postsynaptic neurons. Secondly, excitation has to take place in postsynaptic neurons. These cells also organize themselves into groups specializing in different kinds of information processing. Thus, with new experiences the brain creates more connections and may 'rewire'. The brain organizes and reorganizes itself in response to one's experiences, creating new memories prompted by experience, education, or training. Therefore, the use of a brain reflects how it is organised. This ability to re-organize is especially important if ever a part of the brain becomes damaged. Scientists are unsure of whether the stimuli of what we do not recall are filtered out at the sensory phase
