Use of olfactory training in post-traumatic and postinfectious olfactory dysfunction.
OBJECTIVES/HYPOTHESIS There is evidence that the olfactory system can be modulated by repeated exposure to odors, a procedure called olfactory training. The aim of this study was to assess the effectiveness of olfactory training in patients with postinfectious and post-traumatic olfactory dysfunction. STUDY DESIGN Prospective study of 119 patients with postinfectious and post-traumatic olfact...
متن کاملOlfactory consciousness and gamma oscillation couplings across the olfactory bulb, olfactory cortex, and orbitofrontal cortex
The orbitofrontal cortex receives multi-modality sensory inputs, including olfactory input, and is thought to be involved in conscious perception of the olfactory image of objects. Generation of olfactory consciousness may require neuronal circuit mechanisms for the "binding" of distributed neuronal activities, with each constituent neuron representing a specific component of an olfactory perce...
متن کاملInvestigation of prognostic factors for post-traumatic olfactory dysfunction.
BACKGROUND Post-traumatic olfactory dysfunction is common but has a poor prognosis. The purpose of this study was to analyze the effect of clinical features on improvements in post-traumatic olfactory dysfunction. METHODS From 2007 to 2013, patients with post-traumatic olfactory dysfunction were enrolled. Olfactory function was assessed using the Sniffin' Sticks test at the first and final vi...
متن کاملOlfactory Neuroscience: Beyond the Bulb
High-resolution tracing of projections from the olfactory bulb to its cortical targets revealed coarse topography and stereotopy in some areas but highly distributed, combinatorial connectivity in others. These results provide a basis for understanding innate and associative olfactory processing and perception.
متن کاملAssociative Cortex Features in the First Olfactory Brain Relay Station
Synchronized firing of mitral cells (MCs) in the olfactory bulb (OB) has been hypothesized to help bind information together in olfactory cortex (OC). In this survey of synchronized firing by suspected MCs in awake, behaving vertebrates, we find the surprising result that synchronized firing conveys information on odor value ("Is it rewarded?") rather than odor identity ("What is the odor?"). W...
