How global are olfactory bulb oscillations?
Previous studies in waking animals have shown that the frequency structure of olfactory bulb (OB) local field potential oscillations is very similar across the OB, but large low-impedance surface electrodes may have favored highly coherent events, averaging out local inhomogeneities. We tested the hypothesis that OB oscillations represent spatially homogeneous phenomena at all scales. We used p...
متن کاملP11: Assess the Electrophysiological Activity of Olfactory Bulb in the Animal Model of PTSD and its Relationship with Neuroinflammation in the Olfactory Bulb
Post-traumatic stress disorder (PTSD) is a mental health condition that's triggered by a terrifying event - either experiencing it or witnessing it. In addition to the relationship between PTSD and neuroinflammation, research indicates that olfactory bulb are effective in anxiety disorders. The aim of this study was to assess the electrophysiological activity of olfactory bulb in the animal mod...
متن کاملOlfactory bulb gamma oscillations are enhanced with task demands.
Fast oscillations in neural assemblies have been proposed as a mechanism to facilitate stimulus representation in a variety of sensory systems across animal species. In the olfactory system, intervention studies suggest that oscillations in the gamma frequency range play a role in fine odor discrimination. However, there is still no direct evidence that such oscillations are intrinsically alter...
متن کاملAge-related changes in calretinin-immunoreactive periglomerular cells in the rat main olfactory bulb.
The changes of calretinin (CR)-immunoreactive periglomerular cells in the glomerular layer of the main olfactory bulb (MOB) were investigated in rats differing ages from postnatal month 1 (PM 1) to PM 24. The number of cresyl violet-positive periglomerular cells was similar between PM 1 and PM 12, but they decreased slightly in the PM 24 group. The size of CR-immunoreactive periglomerular cells...
متن کاملCorrelation of olfactory function with changes in the volume of the human olfactory bulb.
OBJECTIVE To investigate changes of olfactory bulb (OB) volume over time in relation to olfactory function. DESIGN Prospective, before-after trial. SETTING Outpatient clinic of a university clinic for otorhinolaryngology. PATIENTS A total of 20 patients with olfactory loss participated in the study. The duration of olfactory deficits ranged from 3 months to 6 years. MAIN OUTCOME MEASURE...
