Monoamine systems and memory formation
Recently, central beta-adrenergic involvement in chick memory processing has become a well-established area of study. This chapter describes a number of experiments which indicate that beta-adrenergic systems play a crucial and specific role in memory formation in the chick. The absence of effect following injection of the antagonists does not interfere with acquisition. The experiments described in the chapter do not entirely exclude the possibility that peripheral sites of action are involved in amnesia. The evidence presented in the chapter suggests that beta-mediated systems are important in memory consolidation. The role of brain noradrenalin in modulation memory storage is as yet unclear. Finally, the chapter emphasises that beta2-mediated noradrenergic activity is crucial for a number of stages of memory formation in the domestic chick.
