Figure 5. Distribution of sites of l-Glu microinjection on coronal sections of the medulla oblongata.

Figure 5

The sites where microinjections of L-Glu produced an increase in intragastric pressure are labeled with upright triangles (σ). The sites with no response or a slight response to injection of l-Glu are labeled with open circles (μ). The sites which produced a decrease in intragastric pressure are labeled with inverted triangles (τ). The distance (in µm) of each section from the obex is indicated in the lower right corner of each section. IV, fourth ventricle; HG, hypoglossal nucleus; AP, area postrema; CC, central channel. Calibration bar: 300 µm.
