| Type | MGI:General | Description | decrease in cortical layer thickness at the somatosensory cortex; decrease in thickness of cortical layers II/III, V, and VI, but no difference in layer IV 25% decrease in thickness of cortical layers V and VI density of NeuN-labeled neurons in layers V and VI of the somatosensory cortex is increased by 27%, however density in layer II/III and IV is normal while there is a decrease in thickness of layers V and VI of the somatosensory cortex, the density of neurons in these layers is increased, indicating that the total number of neurons is unchanged |
