Previous studies indicate that the modification of adrenergic neurotransmission in median raphe nucleus (MRN) enhances or removes an inhibitory influence on food intake, possibly serotonergic, due to a presence of serotonin-producing neurons in that

Previously, we showed that the blockade of α1-adrenoreceptors in the median raphe nucleus (MnR) increased food intake in free-feeding rats, indicating that adrenergic mechanisms in the MnR participate in the regulation of food intake. However, the i

The present study evaluated the involvement of α-adrenoceptors of the median raphe nucleus (MRN) in satiated rats, in food and water intake and motor behaviour. Control groups were treated with saline (SAL) or adrenaline (ADR), injected into the MRN

Previous studies have shown that the blockade of α 1 -adrenoceptors in the median raphe nucleus (MnR) of free-feeding animals increases food intake. Since there is evidence for the presence of α 1A -, α 1B - and α 1D -adrenoceptors in the MnR of
