What reading level is An Outline of Psychobiology book?
To quickly assess the difficulty of the text, read a short excerpt:
In reptiles .and many other animals, the heart continues its contractions after being •completely isolated from the nervous system, and even after being re- moved from the body. If the excitability of the excised heart be increased ■^ Formula given by Starling, Physiology, page 235. Muscular Tissue 37 by immersing it in Biedermann's solution or one of certain other saline solutions, the beating may be prolonged for hours. The stimulus producing the contraction is, in the case of the excised hea...rt, internal ; such can be considered to be the case in the undetached living heart. The nerve currents serve but to increase (or decrease) the excitability of the cardiac muscle, and hence to accelerate (or retard) the spontaneous activity. Chemicals which modify the excitability of the ex- cised heart also modify the excitability of the heart in situ. Cardiac muscle, in addition to its power of periodic contraction without periodic stimulation from outside, and even without any external stimulation, re- sponds to a single external stimulus by a single twitch, as does striated muscle.
