Document Summary
Some psychiatric disorders or mental dysfunctions occur because of abnormal changes in the synaptic structure of the nervous system. Most of the time, these changes are abnormally introduced and are beyond our control. They may be a product of neurotoxins from the environment or part of traumatic experiences that impose pressure and demand on the nervous system. We can also introduce favourable changes within our nervous system, which is within our control, through the process of learning. We are able to sculpt our brain and make it more adaptive in facing challenges in the environment. This model explains how information from the environment is stored in different stages with in the cns. Incoming information from many sensory modalities are first delivered to the first stage of memory storage called sensory memory. Sensory memory is an imprint of environmental stimuli that remain in the sensory receptors.
