Materials and Methods II
Scheme of the experimental set-up.
Results I
Gastric motor responses to cortex stimulation.
Gastric pressure before (grey bar) and after (red bar) stimulation of the anterior cingular (AC), prelimbic (PL) and infralimbic (IL) cortex
Results II
Gastric motor responses to electrical stimulation of the infralimbic cortex (upper tracing) and to the central end of cervical vagus nerve (bottom tracing).
Latency, time to nadir and half recovery time of gastric motor responses to stimulation of cervical vagal afferents (V) or infralimbic stimulation (IL).
Results III
Gastric motor responses to stimulation: (a) vagal, (b) IL, (c) vagal + IL , without lag, (d) vagal +IL with lag.
Magnitude (a), time to nadir (b) and half recovery time (c) of gastric motor responses to stimulation of cervical vagal afferents alone (V) and in combination with infralimbic stimulation (V&IL).
Results IV
The responses of the NTS neurons to IL stimulation (IL) and to cervical afferent stimulation of the vagus (V).
Results V
Responses of NTS neurons to vagal (V) and vagal + infralimbic stimulation (V&IL)
