Internally, severe adhesions, increased fat tissue, and hepatomegaly were recorded, but, without impairing animal health.
The radial arm maze test results demonstrated that acupuncture treatment at ST36 reversed hippocampal-dependent memory in impaired animals.
In the first dose response study, post-training administration of 8-OH-DPAT (0.1 and 0.3 mg/kg, subcutaneously (s.c).) dose-dependently impaired animals' performance in this test.
Understanding the neural bases for grip force behaviors in both normal and neurologically impaired animals is imperative prior to improving treatments and therapeutic approaches.
Young animals used predominantly an allocentric (spatial) search strategy and aged-superior learners appeared to use a combination of allocentric and egocentric (response) strategies, whereas aged-learning impaired animals displayed thigmotactic behavior.
In a first dose-response study, baclofen (0.5, 2, and 4 mg/kg, i.p ., dose-dependently impaired animals' performance in this task, suggesting a modulation of acquisition and storage of information.
BF trkA suppression impaired animals' performance on signal trials in both the sustained attention task (SAT) and the cognitively taxing distractor version of SAT (dSAT) and these deficits were normalized by chronic intracerebroventricular administration of proNGF antibody.
An earlier study demonstrated that the benzodiazepine receptor agonist chlordiazepoxide (CDP), when administered before the phase of preexposure to the to-be-conditioned stimulus, impaired animals' ability to develop LI.
In a first dose response experiments, post-training intra-CA1 injections of phaclofen did not change while baclofen (0.1 μg/mouse) impaired animals' performance in this task, suggesting a modulation of storage of information.
These cellular events suggest a mechanism that could explain reduced cognitive function in the context of Aβ overexpression as well as the rapid recovery of cognitively impaired animals treated with Aβ-lowering drugs.
