Abstract

Tonic immobility is an inborn defensive behavior characterized by a temporary state of profound and reversible motor inhibition elicited by some forms of physical restraint. It is a component of antipredatory behavior and is the last resource used by the prey to reduce the probability of continued attack on the part of the predator, thus being of adaptative value. The study of neural substrate involved in the TI modulation has been investigated in several studies by means of brain sectioning techniques (Arch. Ital. Biol., 109:15-26, 1971), or by peripherical (Behav. Pharmacol., 13:261-69, 2002) or central drug administration (Braz. J. Med. Biol. Res., 23: 723-27, 1990; Physiol. Behav., 67:717-24, 1999; Brain Res. Bull., 58:13-19, 2002; Brain Res. Bull., 50:201-08, 1999), in order to activate different neurotransmissors systems. The functional anatomy of neural circuitry that is activated during TI is, however, only poorly understood. In addition, there is a growing interest to correlate the TI model with catatonia (Psychol. Rev., 111: 984-1002, 2004), depression state in human (Brist. J. Med. Psychol., 71: 417-45,1998; Psychol. Med., 28: 585-98, 1998), or yet as a model for ansiolitic or anxiogenic drugs (Behav. Pharmacol., 13: 261-69, 2002). Therefore it is necessary to understand better the neural substrate involved in the modulation of the defensive behavior of TI in animals. Previous studies of our group demonstrated the involvement of diverse brain structures, such as: parabrachial lateral area (Behav. Brain Res., 56: 127-132, 1993), periaqueductal gray matter (Brain Res. Bull., 50: 201-208, 1999), hypothalamic areas (Neuroreport, 8: 3489-93, 1997), and amygdaloid nuclei (Physiol. Behav., 67: 717-724, 1999) in the TI modulation in guinea pigs... (AU)
