(J. W. C. Hagstrom et al., "Debilitating muscular...)
The myocardium of the posterior base of the left_ventricle was replaced by gray scar tissue over a 7.5 cm. area .
Microscopically , sections from the posterior base of the left_ventricle of the heart showed several large areas of replacement of muscle by fibrous_tissue .
(E. Gellhorn, "Prolegomena to a theory of the emotions"...)
On_the_other_hand , the temporary reduction in hypothalamic excitability through the injection of a barbiturate into the posterior hypothalamus causes a lessening in frequency and amplitude of cortical strychnine spikes until the hypothalamic excitability is restored .
Apparently , a positive_feedback exists between the posterior hypothalamus and the cerebral_cortex .
Since electrical stimulation of the posterior hypothalamus produces the effects of wakefulness while stimulation of the anterior hypothalamus induces sleep , it may be said that the reactivity of the whole organism is altered by a change in the autonomic reactivity of the hypothalamus .Synonyms posterior Related Terms anterior zoology back caudal retral back position
