Abstract

Mediodorsal thalamic (MD) projections to the basolateral amygdaloid complex of the rat were investigated with the anterograde neuronal tracer, Phaseolus vulgaris-leucoagglutinin. Iontophoretic injections were made in distinct subdivisions of the rostral and caudal part of the MD. Both the medial and lateral division of the MD showed a projection to the basolateral complex and there appears to be a topographical organization of the innervation in the rostrocaudal direction: the rostral and caudal part of the MD project to respectively the mid-rostrocaudal and rostral part of the basolateral complex.

      However, Wang et al. (2016) suggest that the effects of DLPFC may be mediated by connections from the lateral prefrontal cortex and rostral ACC to the AMG. They observe decreased FC of the right DLPFC to the right ACC, left cuneus, and left lingual gyrus, in agreement with previous researches (Ghashghaei and Barbas, 2002; Vulpen and Verwer, 1989). The reduced connectivity of DLPFC-ACC is consistent with error monitoring and executive control disruption in MDDs (Schlösser et al., 2008).

      Extant research has identified the lateral/basolateral amygdalar complex (BLA) as a crucial neural locus of fear memory formation. The BLA is well situated to modulate fear learning, as it receives direct projections from the thalamus (via the medial geniculate nucleus) and sensory association cortex (via the external capsule), and sends excitatory afferents to structures responsible for coordinating the behavioral and neuroendocrine responses to stress (van Vulpen and Verwer, 1989; McDonald and Mascagni, 1996; Shi and Cassell, 1997). Importantly, increased excitability of BLA pyramidal projection neurons has been associated with improved acquisition and expression of fear learning (Rogan et al., 1997; Maren, 1999; Gale et al., 2004; Phelps and LeDoux, 2005).
