タイトル: Not all dopaminergic neurons are created equal: heterogeneity and plasticity in the olfactory bulb

日時: 2021年4月22日(木)17:00~18:00 (JST)
場所: Zoom
Dopaminergic (DA) inhibitory interneurons in the olfactory bulb (OB) act at a crucial point in the early olfactory pathway, modulating transmission in OB glomeruli and helping set the gain of incoming inputs. DA neurons are extremely plastic cells, capable of regulating their dopamine production levels in an activity-dependent manner, of undergoing structural plasticity of their dendrites, and even of regenerating throughout life. Long-believed to be a homogeneous population, this talk will explore how recent evidence has instead uncovered a striking heterogeneity in their shape, function and developmental profile – including their ability to undergo adult neurogenesis. Moreover, only a subclass of non-regenerating DA cells has been shown to respond to brief sensory deprivation by implementing structural and intrinsic plastic changes that result in decreased excitability. By specifically acting on one specialised dopaminergic subpopulation, experience-dependent plasticity might act to fine-tune sensory processing in the face of continually fluctuating input.
