Objective: The presence of lymphatic vessels in endometrium has been controversial and recent immunocytochemical studies with routinely paraffin embedded sections revealed lymphatic vessels in basalis and occasionally in functionalis. We aimed to investigate endometrial lymphatic vessels by immunocytochemical staining using cryosections, which provided better and consistent immunostaining for l...

In previous studies involving monkeys performing behavioral tasks, neurons in the nucleus basalis frequently had significant changes in discharge rate when the animal made a movement in response to a sensory stimulus in order to obtain a reward. To determine whether such responses of basalis neurons are primarily sensory or motor in nature, the activity of single basalis neurons was recorded in...

The basal forebrain cholinergic system strongly influences both cortical plasticity and learning. Directly relating these two roles has proven difficult. New results indicate that nucleus basalis lesions prevent motor cortex map plasticity and impair skill learning. These results strengthen the hypothesis that nucleus basalis gates neural plasticity necessary for instrumental learning.

In 22 patients with Alzheimer's disease loss of neurons from the nucleus basalis of Meynert and locus caeruleus averaged 58% and 71% respectively with nucleolar volume being reduced by 30% in both. These changes were greater in those patients under 80 years of age and in such patients damage to the locus was more severe than that to the nucleus basalis. In older patients (over 80 years) changes...

background: alzheimer’s disease was known as a progressive neurodegenerative disorder in the elderly and is characterized by dementia and severe neuronal loss in the some regions of brain such as nucleus basalis magnocellularis. it plays an important role in the brain functions such as learning and memory. loss of cholinergic neurons of nucleus basalis magnocellularis by ibotenic acid can commo...
