Barrel, Barrel column that the neuron belongs to; Distance, the distance (in μm) from the center of cell body to the barrel edge; OBI, Mean OBI (see Materials and Methods) of 9 imaging sessions of the neuron; High, high-OBI neuron, whose OBI was >0.6; Low, low-OBI neuron, whose OBI was <0.5; Medium, neurons whose OBI values were >0.5 and <0.6 were not included in either high-OBI or low-OBI groups; AD, apical dendrite; +, −, mean presence and absence of the apical dendrite, respectively.
*Note that Neuron #1 has only an extremely short (∼30 μm) apical dendrite.
