Cardiovascular and behavioural responses to conditioned fear and restraint are not affected by retrograde lesions of A5 and C1 bulbospinal neurons.

Summary: To investigate the role of A5 neurons in some forms of psychological stress the authors injected 22 or 44 ng of anti-DBH-SAP (Cat. #IT-03) into the spinal cord of rats. Mouse IgG-SAP (Cat. #IT-18) was used as a control. The data shows that A5 presympathetic neurons are not essential for the expression of the tachycardic and pressor responses to conditioned fear and restraint.
