1. A participação de diferentes sistemas neuromodulatórios no hipocampo, núcleo basolateral da amígdala e córtex pré-frontal ventromedial na extinção de memórias aversivas
Extinction consists of the learned inhibition of retrieval of previously acquired memory. Many forms of learning are modulated by ¿-noradrenergic, D1-dopaminergic and H2-histaminergic receptors on ventromedial prefrontal cortex (vmPFC), basolateral amygdala (BLA) and dorsal hippocampus. Therefore, the aim of this work was investigated the modulation of aver

2. The involvement of protein kinases on spatial learning enhancement induced by creatine / O envolvimento de proteínas quinases na facilitação do aprendizado espacial induzido por creatina
Decline cognitive related to neurodegenerative diseases are very commom in patients, probably in function of aging. Since there are few effectives therapeutics approaches to loss memory treatment, but studies about new therapeutics approaches are necessary regarding neuroprotective drugs. Thus, recent works have been showing the efficacy of some neuroprotect

3. Sistemas neuromodulatórios: implicações fisiopatológicas / Neuromodulatory systems: patophysiologic implications
Adenosine has been shown to modulate cardiovascular control at the levels of the nucleus tractus solitarii (NTS). This study shows the distribution and density of adenosine A1 receptor within the nucleus tractus solitarii (NTS) of Wistar Kyoto (WKY) and spontaneously hypertensive (SHR) rats from birth to adulthood (1,15,30 and 90 day-old). [3H]DPCPX was used

4. Glucocorticoid enhancement of memory storage involves noradrenergic activation in the basolateral amygdala
Evidence indicates that the modulatory effects of the adrenergic stress hormone epinephrine as well as several other neuromodulatory systems on memory storage are mediated by activation of β-adrenergic mechanisms in the amygdala. In view of our recent findings indicating that the amygdala is involved in mediating the effects of glucocorticoids on memory sto

5. Tone-Specific and Nonspecific Plasticity of Inferior Colliculus Elicited by Pseudo-Conditioning: Role of Acetylcholine and Auditory and Somatosensory Cortices
Experience-dependent plasticity in the central sensory systems depends on activation of both the sensory and neuromodulatory systems. Sensitization or nonspecific augmentation of central auditory neurons elicited by pseudo-conditioning with unpaired conditioning tonal (CS) and unconditioned electric leg (US) stimuli is quite different from tone-specific plas

6. A genetic approach to trace neural circuits
Mammalian nervous system function involves billions of neurons which are interconnected in a multitude of neural circuits. Here we describe a genetic approach to chart neural circuits. By using an olfactory-specific promoter, we selectively expressed barley lectin in sensory neurons in the olfactory epithelium and vomeronasal organ of transgenic mice. The le

7. Brain-derived neurotrophic factor is an endogenous modulator of nociceptive responses in the spinal cord
The primary sensory neurons that respond to noxious stimulation and project to the spinal cord are known to fall into two distinct groups: one sensitive to nerve growth factor and the other sensitive to glial cell-line-derived neurotrophic factor. There is currently considerable interest in the ways in which these factors may regulate nociceptor propert
