3. Determine how unusual your data must be before it can be considered significant. Many statisticians consider being 95% sure that the null hypothesis is false as a minimum for statistical significance (giving a p-value of 0.05).This is the confidence level..

The role of the amygdala is to set off fear and anger instantly, without conscious thought, so that a person can freeze or run away from danger, Dr. Young said. But the emotion of fear does not reside exclusively in the amygdala because it can be elicited from memory and other brain states.
The hippocampus is one of the few areas of the brain capable actually growing new neurons, although this ability is impaired by stress-related glucocorticoids. The amygdala also performs a primary role in the processing and memory of emotional reactions and social and sexual behaviour, as well as regulating the sense of smell. Another sub-cortical systems (inside the cerebral cortex) which is essential to memory function is the basal ganglia system, particularly the striatum (or neostriatum) which is important in the formation and retrieval of procedural memory.
