Every time you retrieve a memory of an event, it will become more flawed and less
correct. When you retrieve a memory, it gets influenced with newer thought and
emotion. So the memory might no longer be same as before.
The cerebral cortex (grey matter) has different areas with different functions.
Frontal lobe: this part is responsible for our cognitive functions, emotional
expressions, abstract thinking, our spoken language, planning, executive functions,
our self-image (ego) and even most likely our consciousness.
Parietal lobe: This part processes the sensory information it receives from all over
the body.
Occipital lobe: Responsible for visual processing.
Temporal lobe: Sound and the auditory language is processed here.
The cerebellum is controlling the motor functions of our body.
