Long term memory lasts for longer periods (even for life time) and can hold much more information than the short term memory. The two types of long term memory are,
• Declarative or explicit memory
• Implicit or non-declarative memory
Implicit memory or the non-declarative memory involves the unintentional remembering. The amygdala of basal ganglia is associated with the non-declarative memory.
Thus, the blank can be filled with Basal ganglia.
