[2] The physical characteristics of basal dendrites vary based on their location and species that they are found in.
[4] Basal dendrites additionally exist in dentate granule cells for a limited time before removal via regulatory factors.
[5] This removal usually occurs before the cell reaches adulthood, and is thought to be regulated through both intracellular and extracellular signals.
[7] These arbors are classified as sampling because they are not completely space filling, but make more than one specific, or selective connection.
