“…The prevailing interpretation emerging from these studies is that neuromodulators gate cortical plasticity by enhancing sensory perception, and by promoting patterns of cortical activity suitable for plasticity induction via controlling network excitability. This is consistent with a wealth of studies documenting that neuromodulators improve perception in vivo (see Gelbard-Sagiv et al, 2018;Jacob and Nienborg, 2018;McBurney-Lin et al, 2019;Nadim and Bucher, 2014 for reviews) also affect cellular intrinsic excitability and synaptic inhibition to gate the induction of Hebbian plasticity in vitro (see Brzosko et al, 2019;Palacios-Filardo and Mellor, 2019;Pawlak et al, 2010 for reviews). We propose an additional and different mode of action: direct control of the expression, not the induction, of Hebbian plasticity via the Gq/Gs based pull-push metaplasticity mechanism that we previously demonstrated in vitro, in slices.…”

“…The most prominent effect of the NA is the modulation of synaptic transmission and various forms of plasticity (Harley, 1987;Mouradian et al, 1991;Sara, 2009), which are analogous to those of DA (Seamans and Yang, 2004;Tritsch and Sabatini, 2012;Froemke, 2015). In various sensory systems, both dopaminergic and noradrenergic systems were effective in remodeling the tuning properties of the cortical neurons (Bao et al, 2001;Manunta and Edeline, 2004;Edeline et al, 2011;Martins and Froemke, 2015;McBurney-Lin et al, 2019;Waterhouse and Navarra, 2019). Notably, both systems also contribute to the maintenance and transitions of global brain states, wakefulness, arousal, attention, and memory consolidation (Berridge, 2008;Carter et al, 2010;Lee and Dan, 2012;Eban-Rothschild et al, 2016;Fazlali et al, 2016;Sara, 2017;Schicknick et al, 2019).…”

“…The role of LC phasic response in mediating the orienting response and attention is well known 16 . Salient stimuli elicit phasic discharge of LC neurons 17 , 18 and associated noradrenaline (NA) release in the LC forebrain targets affects sensory processing 19 , 20 , including auditory 21 23 . The results of pharmacological and lesion studies suggested that the LC-NA system exerts an excitatory effect on the ASR circuit 24 – 27 .…”
