Lunar enterprises and development,ct with neighbors, are capable of spontaneous rhythmic activity when maintained under suitable in vitro culture conditions.*. Any such single isolated cell which is seen to beat must be initiating its own activity, and may thus be defined as a pacemaker.. Moreover, such a cell, within 5–30 min after

We have observed reversal in many active pulsating blood vessels, both in vertebrates and in invertebrates, and even in embryonic heart tubes. Using four or five suction electrodes simultaneously, we were able to record electrical activity

It seems appropriate to adopt this new terminology, since the ganglia have been previously referred to in the literature as the lateral heart nerves.*, aortal nerves., lateral cardiac nerves., and lateral cardiac nerve cords.. These diffuse ganglia, each containing 15–20 intrin

Though automobile manufacturers always claim good performance for their car engines, the controlled performance of the heart sets the engineers new standards, as biological engineers have realized now that they have come to design artif
