Histogenesis of Olfactory Bulbs in Human Foetus
2. Materials and Methods Histogenesis of olfactory bulb was studied in 62 human foetuses. The olfactory bulbs were removed en block with the surrounding bone and fixed in 10 percent formal saline. Serial sections of paraffin embedded tissue were stained with H/E, cresyl violet and Glees Marsland's modification of Bielschowsky's staining method for neurites. Klüver and Barrera's method was used ...
متن کاملThe olfactory bulbs in Alzheimer's disease.
The olfactory bulbs have been examined in patients with Alzheimer's disease and compared with those in elderly undemented and younger undemented control patients. In Alzheimer's disease neurofibrillary tangles were found in the anterior olfactory nucleus but not elsewhere in the olfactory bulb. Cell loss in the anterior olfactory nucleus was also found in Alzheimer's disease. It is clear that t...

این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...
15 صفحه اولNeural Sensitivity to Odorants in Deprived and Normal Olfactory Bulbs
Early olfactory deprivation in rodents is accompanied by an homeostatic regulation of the synaptic connectivity in the olfactory bulb (OB). However, its consequences in the neural sensitivity and discrimination have not been elucidated. We compared the odorant sensitivity and discrimination in early sensory deprived and normal OBs in anesthetized rats. We show that the deprived OB exhibits an i...
متن کاملDifferential serotonergic modulation across the main and accessory olfactory bulbs.
KEY POINTS There are serotonergic projections to both the main (MOB) and the accessory olfactory bulb (AOB). Current-clamp experiments demonstrate that serotonergic afferents are largely excitatory for mitral cells (MCs) in the MOB where 5-HT2A receptors mediate a direct excitatory action. Serotonergic afferents are predominately inhibitory for MCs in the AOB. There are two types of inhibition:...
