Table 1. Electrophysiological characteristics of spontaneously active habenula neurons following MnCl₂ injection.

Region	Number of tracks	# Cells/track Mean ± SEM	Spontaneous Firing Rate, Hz (Pearson’s r, n)	Spike Width*, ms (Pearson’s r, n)
MHb	7	6.7 ± 1.1	5.5 ± 0.6	0.8 ± 0.05
			(0.14, 47)	(-0.03, 43)
LHb(m)	8	2.6 ± 0.7	15.9 ± 3.3	0.5 ± 0.05
			(0.30, 21)	(0.34, 19)
LHB (l)	8	2.8 ± 0.5	8.2 ± 2.1	0.4 ± 0.03
			(0.17, 22)	(0.06, 20)

All values represent the mean ± SEM. There were no significant correlations with time from injection (all p-values > 0.05).

* Spike width was measured at half-amplitude (peak-to-peak).
