basolateral amygdalar nucleus

basolateral amygdalar nucleus (BLA)

The term basolateral amygdalar nucleus (AMGbl) refers to a combination of three nuclei of the amygdala (AMG), which are located between the lateral amygdalar nucleus (AMGl) and the more medial accessory basal nucleus (AMGab). In the human and the macaque, it is identified by histology with multiple stains and is composed of the large, more dorsal parvicellular basolateral amygdalar nucleus (AMGblpv), the intermediate magnocellular basolateral amygdalar nucleus (AMGblmc) and the much thinner, most ventral paralaminar amygdalar nucleus (AMGpl) ( Amaral-1992 ). In the rat ( Paxinos-2009b Swanson-2004 ) and mouse ( Hof-2000 ), the AMBbl is subdivided by location rather than by histological criteria: anterior part of the basolateral nucleus (AMGbla), posterior part of the basolateral nucleus (AMGblp), ventral part of the basolateral nucleus (AMGblv).

Models Where It Appears

Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.

Functional CNS Model - Rat

The Functional CNS Model - Rat (FMrat) ( Swanson-2004) is one of three hierarchical models representing the internal organization of the central nervous system (CNS). The others are the Structural CNS Model - Human (SThmn) and the Functional CNS Model - Human (FMhmn). The FMrat model represents the basic organization of the mouse ( Hof-2000 AMBA-2024 ) and, presumably, other rodents. Functional CNS models differ from structural models in that structures are defined and named by connectivity rather than by proximity to other structures at the same level. Functional models are more useful for representing longitudinal components of are grouped based on information drawn from multiple neuroscientific disciplines. such as connections, neurochemical characteristics, and role in physiogical and behavioral processes. While the Functional Model was developed primarily for an atlas of the rat brain ( Swanson-2004 ), the hierarchical organization of structures is for the most part applicable to the human, macaque, mouse and other mammalian brains as well. Structures at lower levels of the Functional CNS hierarchy are largely the same as in the Classical and Developmental Models, i.e., they were originally identified by stains for gray matter (Nissl substance) and white matter (myelin). At the next higher level they are grouped into basic connectional and functional systems of the CNS, such as the subcortical sensory systems, the brainstem motor system and the behavioral state system. At the highest levels CNS structures are grouped on the basis of dissection and embryologic precursors into cerebrum ( cerebral cortex and cerebral nuclei ), cerebellum, and cerebrospinal trunk.
