Figure 7.

Morphometric features of astrocytes from different brainstem regions. (a–d) Summary morphometric data illustrating the number of terminals (a), number of branch points (b), number of primary branches originating from the soma (c), and total process length (d) of preBötC (n = 19), IRF (n = 10), and NTS (n = 10) astrocytes. (e,f) Summary data of the convex hull volume (e) and surface area (f) of astrocytes in the preBötC, IRF, and the NTS. PreBötC astrocytes have longer processes, more branch points and terminals, and greater convex hull volume and surface area, compared to IRF and NTS astrocytes. Data sets without p values indicated are not significantly different
