Butt AE, Cabrera S, Chavez C, Corley S, Cortez A, Figueroa J, Kitto M, Torner E (2005) Basal forebrain cholinergic lesions produce a dissociation of impairment in delay and trace conditioning in rats. Neuroscience 2005 Abstracts 644.2. Society for Neuroscience, Washington, DC. Summary: Recent research suggests that Pavlovian trace conditioning, but not delay conditioning, requires […]

Fadel J, Frederick-Duus D, Butts R (2005) Orexin lesions block food-related increases in cortical acetylcholine release. Neuroscience 2005 Abstracts 644.8. Society for Neuroscience, Washington, DC. Summary: Hypothalamic orexin (hypocretin) neurons influence and coordinate arousal, state-dependent behavior, feeding and metabolic processes. Orexin fibers are seen in close proximity to choline acetyltransferase (ChAT)-positive magnocellular somata in portions

Strait TA, Montoya D, Pang KCH (2005) Role of the medial septum in a repeated acquisition task. Neuroscience 2005 Abstracts 647.14. Society for Neuroscience, Washington, DC. Summary: The medial septum/diagonal band of Broca (MSDB) provides a major afferent pathway to the hippocampus and both regions are important in learning and memory. The two major projection

Lohals R, Veng LM (2005) Cholinergic therapy does not rescue spatial learning deficits induced by ICV injection of 192 IgG-saporin. Neuroscience 2005 Abstracts 653.5. Society for Neuroscience, Washington, DC. Summary: The cholinergic hypothesis states that central cholinergic dysfunction is responsible for age-dependent cognitive decline. To model this in rats, we induced cholinergic basal forebrain loss

Knox DK, Berntson GG (2005) The potential role of the corticopetal cholinergic system in mediating anxiogenic states in rats. Neuroscience 2005 Abstracts 659.10. Society for Neuroscience, Washington, DC. Summary: Previous research has demonstrated that the corticopetal cholinergic system is important in mediating defensive tachycardia which suggests that this system may be important in mediating aversive

Stead S, Trottier N, Doering LC (2005) Characterization of an immunotoxin model of Parkinson’s disease in mice. Neuroscience 2005 Abstracts 664.9. Society for Neuroscience, Washington, DC. Summary: The primary event underlying the motor deficits of Parkinson’s disease (PD) is degeneration of neurons in the nigro-striatal system. The most widely employed laboratory rodent models of Parkinson’s

Fargo KN, Sengelaub DR (2005) Testosterone treatment prevents deficits in motor activation caused by partial loss of motoneurons. Neuroscience 2005 Abstracts 672.8. Society for Neuroscience, Washington, DC. Summary: In male rats, motoneurons of the spinal nucleus of the bulbocavernosus (SNB) project to the bulbocavernosus and levator ani muscles (BC/LA). The SNB system is dependent on

Fraley GS (2005) Immunolesions of glucoresponsive projections to the arcuate nucleus alter glucoprivic feeding and luteinizing hormone secretion but not sex behavior in adult male rats. Neuroscience 2005 Abstracts 758.7. Society for Neuroscience, Washington, DC. Summary: Metabolic signals such as insulin, leptin and glucose are known to alter hypothalamic function. Although insulin and leptin are

Vijayakumar S, Masood A, Smith M, Clark JP, Nelson DE, Ding JM (2005) Immunolesion of p75 NGF receptor in the mouse SCN attenuated light-induced phase shift of the circadian wheel-running rhythm. Neuroscience 2005 Abstracts 766.18. Society for Neuroscience, Washington, DC. Summary: Mammalian circadian rhythms are regulated by the suprachiasmatic nucleus (SCN) of the hypothalamus. Alhough

Greene DM, Castillo MR, Alexander KA, McMahan A, Raap DK, Bult-Ito A (2005) Neurotoxic lesions of serotonin cells in the dorsal raphe reduce compulsive-like nest building in mice. Neuroscience 2005 Abstracts 796.10. Society for Neuroscience, Washington, DC. Summary: Bi-directional selection for thermoregulatory nest-building behavior in house mice (Mus musculus) has resulted in a 40-fold difference
