Contributed by Lique M. Coolen, University of Michigan Introduction from Dr. Lappi: An article by Lique Coolen’s group[5] was the 1000th article in PubMed in response to the search word ‘saporin.’ Dr. Coolen has graciously agreed to describe the latest in her fascinating work. Male sexual behavior consists of many different aspects, with ejaculation being

Peptidergic Edinger-Westphal neurons and the energy-dependent stress response

Xu L, Scheenen WJ, Roubos EW, Kozicz T (2012) Peptidergic Edinger-Westphal neurons and the energy-dependent stress response. Gen Comp Endocrinol 177(3):296-304. doi: 10.1016/j.ygcen.2011.11.039 Objective: This study investigates the role of the midbrain Edinger–Westphal centrally projecting neuron population (EWcp; synonym: non-preganglionic Edinger–Westphal nucleus) in the energy-dependent stress adaptation response. Summary: The current data indicates that the

Brainstem facilitations and descending serotonergic controls contribute to visceral nociception but not pregabalin analgesia in rats.

Sikandar S, Bannister K, Dickenson AH (2012) Brainstem facilitations and descending serotonergic controls contribute to visceral nociception but not pregabalin analgesia in rats. Neurosci Lett 519(1):31-36. doi: 10.1016/j.neulet.2012.05.009 Summary: Neurons in the rostral ventromedial medulla (RVM) are classified as ON, OFF, or NEUTRAL based on firing patterns in response to noxious somatic stimulation. ON cells

A nociceptive signaling role for neuromedin B.

Mishra SK, Holzman S, Hoon MA (2012) A nociceptive signaling role for neuromedin B. J Neurosci 32(25):8686-8695. doi: 10.1523/JNEUROSCI.1533-12.2012 Summary: Previous work suggests that neuromedin B (NMB) is involved in nociception. Direct injection of the peptide causes nociceptive sensitization, while NMB antagonists attenuate sensitization in reponse to nerve stimulation with mustard oil. Specific subsets of

Vestibular stimulation enhances hippocampal long-term potentiation via activation of cholinergic septohippocampal cells.

Tai SK, Leung LS (2012) Vestibular stimulation enhances hippocampal long-term potentiation via activation of cholinergic septohippocampal cells. Behav Brain Res 232(1):174-182. doi: 10.1016/j.bbr.2012.04.013 Summary: It is known that vestibular stimulation induces acetylcholine release in the hippocampus. The authors hypothesized that this stimulation enhances long-term potentiation (LTP) in CA1 and depends on the activation of septohippocampal

C1 neurons excite locus coeruleus and A5 noradrenergic neurons along with sympathetic outflow in rats.

Abbott SB, Kanbar R, Bochorishvili G, Coates MB, Stornetta RL, Guyenet PG (2012) C1 neurons excite locus coeruleus and A5 noradrenergic neurons along with sympathetic outflow in rats. J Physiol 590(12):2897-2915. doi: 10.1113/jphysiol.2012.232157 Summary: C1 neurons are known to activate sympathetic tone and stimulate the hypothalamic-pituitary-adrenal axis. C1 activation is also reported to inhibit locus
