Fig. 1.

Reconstructed linear absorption coefficients of a mature mouse olfactory sensory neuron. The cell was cryogenically preserved, and then imaged within a glass capillary (the white ring). (a) and (b) show two z-plane slices through the underlying three-dimensional reconstruction. The cell completely fills the capillary in both images. The cell’s nucleus is visible as the circular structure with large regions of lower LAC values (darker pixels). The full 3D reconstruction of this nucleus is shown in Fig. 2. In the figures, LACs have units of per voxel. Each LAC value divided by the voxel length of 32 nm would have the more standard units of nm⁻¹ (Color figure online)
