Orexin-A (Hypocretin-1) has been localized in the posterior and lateral hypothalamic perifornical region. Orexin containing axon terminals have been found in hypothalamic nuclei and many other parts of the brain; for example, the hippocampus. Two typ

Angiotensins have been shown to play a significant role in a variety of physiological functions including learning and memory processes. Relatively recent evidence supports the increasing importance of angiotensin IV (Ang IV), in many of these functi

Within the brain-renin angiotensin system, it is generally assumed that angiotensin peptide fragments shorter than angiotensins II and III, including angiotensin IV (AngIV), are inactive. This belief has been challenged by the recent discovery that A

Air righting results in an animal turning over when it is dropped from a height in an inverted position. In the rat, air righting is a complex set of movements that depends only on an intact labyrinth and the normal vestibular input. Visual modulatio

We previously reported that injection of 1.0 microliter of 4.78 microM angiotensin II (AII) above the hippocampus in rats inhibits long-term potentiation (LTP) induction in medial perforant path-stimulated dentate granule cells. The present experimen

Results of a previous study showed that angiotensin II (AII) inhibited the induction of long-term potentiation (LTP) in hippocampal granule cells in response to dorsomedial perforant path stimulation in urethane-anesthetized rats. The results of pres

Angiotensin II (AII) inhibits the induction of hippocampal long-term potentiation (LTP), a frequency-dependent model of learning and memory. These results demonstrate that the dose-dependent inhibition of LTP due to ethanol (EtOH) and diazepam (DZ) i

The use of in vitro brain slice preparations has increased in the past ten years, particularly the hippocampal slice because of the dissection ease, well-defined cell layers, and self-contained afferent systems. Developing the slice as a model for sc
