Muscarinic Modulation Of Basolateral Amygdala, Lei Liu
Theses and Dissertations
The basolateral amygdala (BL) receives a dense cholinergic innervation from the basal forebrain. Despite the importance of muscarinic acetylcholine receptors (mAChRs) in fear learning, consolidation, and extinction, there have been no studies that have systematically investigated the functional role of mAChRs in regulating emotional processing in the BL. To address this critical knowledge gap we combined brain slice whole-cell recording, optogenetics, and immunohistochemistry to determine how muscarine, acting on mAChRs, regulates neuronal oscillations, synaptic transmission and plasticity in the BL.
Neurons in the BL oscillate rhythmically during emotional processing, which are thought to be important to integrate sensory inputs, allow …
