PMID: 31316329
The chances to succeed in goal-directed behaviors, such as food or water-seeking, improve when the subject is in an increased arousal state. The appetitive phase of these motivated behaviors is...

J Neurophysiol
. 2018 Aug;
120(4):1906-1913.
PMID: 30133379
The interoceptive insular cortex is known to be involved in the perception of bodily states and emotions. Increasing evidence points to an additional role for the insula in the storage...

. 2015 Mar;
26(4):338-44.
PMID: 25746330
Appetitive behaviours occur in a state of behavioural and physiological activation that allows the optimal performance of these goal-directed behaviours. Here, we tested the hypothesis that histamine neurons under the...
