Cardiac Output and Blood Flow Distribution during Rest and Classical Aversive Conditioning in Monkey

Cardiac Output and Blood Flow Distribution during Rest and Classical Aversive Conditioning in Monkey

ABSTRACT Cardiac output was measured by dye dilution in rhesus monkeys (n = 9) during rest and classical aversive conditioning. A 1‐ min tone (followed by unavoidable electric shock) served as the conditional stimulus (CS +). Cardiac output was determined at approximately 30 sec before and after ons...

Zusammenfassung:ABSTRACT Cardiac output was measured by dye dilution in rhesus monkeys (n = 9) during rest and classical aversive conditioning. A 1‐ min tone (followed by unavoidable electric shock) served as the conditional stimulus (CS +). Cardiac output was determined at approximately 30 sec before and after onset of CS +. Conditional increases in mean blood pressure (78± 11 to 84±11 mmHg. average±SD) and heart rate (145±23 to 166 ± 31/min) were associated with a significant (p
