Table 1. Neurons by region.

Table shows how many subjects had at least one neuron in each brain region, how many neurons were recorded in each region, and the median, lower-, and upper-quartile firing rates for these neurons.

Region	Subjects	Neurons	Firing rate (Hz)
Hippocampus	27	391	1.6 (0.6, 4.7)
Entorhinal cortex	19	341	2.3 (1.0, 5.5)
Amygdala	23	439	1.5 (0.6, 3.7)
Parahippocampal gyrus	15	217	2.2 (0.8, 4.5)
Superior temporal gyrus	5	139	3.4 (1.4, 8.6)
Orbitofrontal cortex	15	193	2.0 (0.9, 4.9)
Anterior cingulate cortex	8	134	3.1 (1.4, 6.8)
Total	28	1854	2.0 (0.8, 5.0 )
