k structures can still retrieve old information calls into question theories that these structures transfer information into long-term memory. This has caused researchers to propose that long-term memory is located in the cerebral cortex, especially the association and polymodal areas. There is much evidence for this in the facts that the cortex has sufficient neuronal capacity for such storage and there is apparent trace decay in patients sustaining widespread cortical damage. However, it is still not known whether particular bits of information are stored in singular neuronal modules or in widespread neuronal networks. It is also not known whether data is stored in singular bits or in large agglomerates of bits, and whether or not the glial cells are involved in memory storage and transfer. It is also possible that the cortical regions may need cooperation from emotion-coding regions such as the septum or amygdala of the brain to record a complete event, including its emotional compon
