Serotonin release in lateral and medial hypothalamus during feeding and its anticipation
DH Schwartz, L Hernandez, BG Hoebel - Brain research bulletin, 1990 - Elsevier
In the present experiments we extend previous findings that established a relationship
between feeding behavior and hypothalamic serotonin as measured by in vivo
microdialysis. The new result is hypothalamic release of serotonin in anticipation of eating
when the animal sees and smells food. We have now verified brain serotonin peaks in four
different ways: 1. 1) a serotonergic reuptake blocker (fluoxetine 1 or 10 μM) in the perfusion
medium raised basal levels of serotonin. 2. 2) every sample was oxidized at two potentials …
