Question

Discuss and differentiate between the ways the brain is activated when we have memories. Your response should include a discussion of the different parts of the brain that are involved in memory, and their specific relationship to the different kinds of memory. Your answer should reflect a broad knowledge of the neurophysiology of memory.

Answer 1

ANS) Memories in brain stored in different parts i.e.1) EXPLICIT MEMORIES- This is about the events happened to you.2) IMPLICIT MEMORIES-rely on the basal ganglia and cerebellum ,also called motor memories. 3) Short-term working memory relies most heavily on the prefrontal cortex.

There is also three important areas in the brain that is- the hippocampus, the neocortex and the amygdala.

The hippocampus, located in the brain's temporal lobe, is where sporadic memories are formed and indexed for later use.The Neocortex is the largest part of the cerebral cortex, the sheet of the neural tissue that forms the outer surface of the brain.the neocortex is involved in higher functions such as sensory perception, generation of motor commands.languages,etc. The amygdala is an almond-shaped structure in the brain’s lobe, attaches emotional significance to memories. This is particularly important because strong emotional memories (i.e. shame, joy, love,etc) are difficult to forget.

In implicit Memory there is also two structural areas presented 1)Basal Ganglia 2) Cerebellum.Basal ganglia is present deep inside brain and has a wide range of processess i.e.emotion,habits proccesiing,learning,etc. Cerebellum is located at rear base of the brain,its feel like a sensation in your brain,whenever you touch as an effect comes as a soft noise.

During the recalling proccess, the brain replays a pattern of neural activity that was originally generated in response to a particular event, echoes the brain's perception of the real event. In fact, there is no real solid seperation between the act of remembering and the act of thinking.The way memories are encoded and stored, memory recall is effectively on the fly reconstruction of elements Randomly distributed throughout various parts of Human Brain.

Our Memory cognitive processess requires re-visiting the nerve pathways the brain formed when encoding the memory, and the strength of those pathways determines how quickly the memory can be bring back. Recalling effectively returns a memory from long-term storage to short-term, where it can be accessed for encoding process. It is then re-stored back in long-term memory, thus re-consolidating and strengthening it.
