Assessing olfaction following pediatric traumatic brain injury.
A brief procedure for screening the olfactory function in elementary-age children was developed in the present investigation When the performance of pediatric patients with mild traumatic brain injury (TBI) was compared with that of a matched sample with severe TBI, the severe TBI sample was one and one-half times as likely to exhibit an impaired sense of smell of formal testing (p<0 05) Subseq...

to glutamate before the establishment of synaptic connections with mitral cells at the more distal portions of their dendritic arbors (Panzanelli et al., 2009). In addition, olfactory deprivation differentially affects spine density in the distal and proximal dendritic domains, where respectively centripetal and centrifugal synaptic connections take place (Kelsch et al., 2009). Hence, the role ...
متن کاملActivation and habituation in olfaction--an fMRI study.
This study investigated human BOLD responses in primary and higher order olfactory cortices following presentation of short- and long-duration odorant stimuli using a 3-T MR scanner. The goal was to identify temporal differences in the course of the response that might underlie habituation. A short-duration stimulus (9 s) consistently activated the primary olfactory cortex (POC). After a long s...
متن کاملOlfaction.
The main and accessory olfactory systems have received considerable attention on the part of scientists and clinicians during the last decade, largely because of (a) quantum advances in understanding their genetically expressed receptor mechanisms, (b) evidence that their receptor cells undergo neurogenesis and both programmed and induced cell death, and (c) important technical and practical de...
متن کاملTo smell the immune system: olfaction, autoimmunity and brain involvement.
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...
