FIG. I22a. Case i. From left to right: responses to a deep inspiration, four pin-pricks
on face and a further deep inspiration. From above downwards:
Insp.
4- = respiratory
record inspiration downwards:
LTi
f = left big toe volume, dilatation upwards;
Sig.
=
signal for pin-pricks;
LF2
j — left index finger volume, dilatation downwards.
Finger vaso-constriction accompanies deep inspiration but not pin-pricks, b. Case 2. Two
sections of record to show responses to
(a)
deep inspiration, and (6) two auditory stimuli,
shown by signal, followed by deep inspiration. Symbols as in Fig. 1223. Finger and toe
vaso-constriction accompanies deep inspiration but not auditory stimuli. Case 5. From left
to right: responses to a deep inspiration. Ice applied to face during signal and a further
deep inspiration. The finger constricts poorly to both toe and deep inspiration while
the toe responds only to deep inspiration. Symbols as in Fig. i. From R.W.Gilliatt,
L.Guttmann and D.Whitteridge. 1947. Inspiratory vaso-constriction after spinal injuries.
