Remodeling of the piriform cortex after lesion in adult rodents
Denervation of the piriform cortex by bulbotomy causes a series of important cellular changes in the inhibitory interneurons of layer I and transsynaptic apoptosis of a large number of pyramidal neurons in outer layer II within 24 h. In this study, we report that following the marked loss of neurons in outer layer II, the piriform cortex is reconstituted by the addition of newly formed neurons ...
متن کاملChandelier and Interfascicular Neurons in the Adult Mouse Piriform Cortex
The structure of two neuron types native to the adult mouse piriform cortex (PC) is described. The first cell, termed an interfascicular neuron (IFN), lies between the axon fascicles of layer I. The IFN axon divides dichotomously and daughter fibrils run horizontally in the domain of layer Ia. The frequent apposition of the IFN axon to distal dendrites of the underlying pyramidal cells suggests...
متن کاملConvergence in the Piriform Cortex
How are the responses to distinct chemical features integrated to form an olfactory perceptual object? In this issue of Neuron, Davison and Ehlers show that individual piriform cortex neurons receive convergent input from up to 10% of main olfactory bulb glomeruli and are activated by specific spatial patterns of coactive glomeruli.
متن کاملThe effect of parameters of low-frequency electrical stimulation on piriform-cortex kindled seizures in rat
Introduction: Electrical low-frequency stimulation (LFS) has antiepileptic effect, but the role of different stimulation parameters on this effect has not been determined. In this study the effect of different LFS parameters (intensity, pulse duration and train duration) on piriform-cortex kindled seizures was investigated. Methods: Seizure was produced in animals using kindling model of ep...
متن کاملRepresentations of Odor in the Piriform Cortex
Olfactory perception is initiated by the recognition of odorants by a large repertoire of receptors in the sensory epithelium. A dispersed pattern of neural activity in the nose is converted into a segregated map in the olfactory bulb. How is this representation transformed at the next processing center for olfactory information, the piriform cortex? Optical imaging of odorant responses in the ...
