Aside from its recognition and warning functions, olfaction serves many purposes in the CNS and remains one of the most important means of communication with the environment. In addition to olfactory tract input, the olfactory bulb also receives and provides input to other brain centers that modify neuronal activity. Research in the field of immunology as well as in various brain illnesses is b...

CHARGE is a multiple congenital anomaly disorder and a common cause of pubertal defects, olfactory dysfunction, growth delays, deaf-blindness, balance disorders and congenital heart malformations. Mutations in CHD7, the gene encoding chromodomain helicase DNA binding protein 7, are present in 60-80% of individuals with the CHARGE syndrome. Mutations in CHD7 have also been reported in the Kallma...

It has been known for over 30 years that olfactory function is disordered in idiopathic Parkinson's disease (IPD). The severity and partial specificity of anosmia was not realized until recently, with the advent of more detailed analysis and sophisticated measurement. The olfactory vector hypothesis suggests that the causative agent for IPD enters the brain via the nasal route, but the reason f...

organization of various cells lining the olfactory mucosa of puntius ticto (hamilton, 1822) were described by light as well as scanning electron microscopy. the paired olfactory chambers located antero-dorsal to the eyes and communicated outside through anterior and posterior nasal openings. the oval shaped olfactory rosette lied at the bottom of chamber and composed of 18-20 lamellae arranged ...

<b><i>Introduction:</i></b> Patients with chemosensory dysfunction frequently report symptoms of depression. The current study aims to clarify whether the type (smell dysfunction, taste and mixed smell dysfunction), severity, duration, or cause have differential impacts on <b><i>Methods:</i></b> 899 patients disorders 62 controls were included. Fo...

INTRODUCTION The piriform cortex and cortical amygdala (PCA) and the orbitofrontal cortex (OFC) are considered olfactory-related brain regions. This study aims to elucidate the normal volumes of PCA and OFC of each age groups (20.0-70.0 year old), and whether the volumes of PCA and OFC decline with increasing age and diminishing olfactory function. METHODS One hundred and eleven healthy right...

There are no reports for anosmia after caudal epidural steroid injections (CESIs). General anesthesia is among the reasons, but the reports up to date are extremely limited. There are no identifiable factors contributing to anosmia after epidural injection, so it is worth discussing. We present the case of a 50-year-old woman with no previous history of any sensory deficits. She experienced ano...

Understanding the biology of adult neural stem cells has important implications for nervous system development and may contribute to our understanding of neurodegenerative disorders and their treatment. We have characterized the process of olfactory neurogenesis in adult mice lacking inhibitor of DNA binding 2(-/-) (Id2(-/-)). We found a diminished olfactory bulb containing reduced numbers of g...

Increasing interest is being shown in the link between olfaction, a complex sensory system, and cognition, particularly in the elderly. Olfaction is known to affect cognitive abilities and mood. In this article, we consider the impairment of olfactory function due to Alzheimer disease (AD), Parkinson disease (PD) and Lewy body disease (LBD), through pathological changes in the peripheral and ce...
