Observed and expected distributions of gold particles in compartments of pyramidal neurons and CPrP cells, relative labeling index, and χ² values^a

Compartments	Number of observed gold particles, no	Number of grid points, P	Normalized number of expected gold particles, ne = P(total no/total P)	Relative labeling index, no/ne	Partial χ2 values, (no - ne)2/ne
Pyramidal neurons
Nucleus	11	421	181	0.06	160
Mitochondria	5	69	30	0.24	20
Cytosol	13	799	344	0.04	318
CPrP cells
Nucleus	26	227	98	0.27	51
Mitochondria	27	105	45	0.6	7.2
Cytosol	908	678	292	3.12b	1308b
Totals	990	2299	990	1	1864.2c

^a The values were quantified for 10 cells in each category.

^b Indicates compartment is preferentially labeled.

^c The distribution is nonrandom, with p < 0.001.
