Norepinephrine ignites local hotspots of neuronal excitation: How arousal amplifies selectivity in perception and memory
Emotional arousal enhances perception and memory of high-priority information but impairs
processing of other information. Here, we propose that, under arousal, local glutamate levels …

Précis on the cognitive-emotional brain
L Pessoa - Behavioral and Brain Sciences, 2015 - cambridge.org
In The Cognitive-Emotional Brain (Pessoa 2013), I describe the many ways that emotion and
cognition interact and are integrated in the brain. The book summarizes five areas of …

Noradrenergic signaling in infralimbic cortex increases cell excitability and strengthens memory for fear extinction
Emotional arousal strengthens memory. This is most apparent in aversive conditioning, in
which the stress-related neurotransmitter norepinephrine (NE) enhances associations …

Noradrenergic modulation of fear conditioning and extinction
TF Giustino, S Maren - Frontiers in behavioral neuroscience, 2018 - frontiersin.org
The locus coeruleus norepinephrine (LC-NE) system plays a broad role in learning and
memory. Here we begin with an overview of the LC-NE system. We then consider how both …

[PDF][PDF] Beyond brain regions: Network perspective of cognition–emotion interactions
Lindquist et al. provide a convincing case against what they call the locationist account of
emotion. Their quantitative approach elegantly illustrates the shortcomings of this still …

Locus coeruleus activity strengthens prioritized memories under arousal
Recent models posit that bursts of locus ceruleus (LC) activity amplify neural gain such that
limited attention and encoding resources focus even more on prioritized mental …

Emotion enhances learning via norepinephrine regulation of AMPA-receptor trafficking
Emotion enhances our ability to form vivid memories of even trivial events. Norepinephrine
(NE), a neuromodulator released during emotional arousal, plays a central role in the …
