Receptive fields in the rat piriform cortex.
Current models of odor discrimination in mammals involve molecular feature detection by a large family of diverse olfactory receptors, refinement of molecular feature extraction through precise projections of olfactory receptor neurons to the olfactory bulb to form an odor-specific spatial map of molecular features across glomerular layer, and synthesis of these features into odor objects withi...
متن کاملBinaral interactions in the rat piriform cortex.
Single-unit recordings were made from layer II/III anterior piriform cortex (aPCX) neurons in adult Wistar rats to examine odor response patterns to unilaterally and bilaterally delivered stimuli. Isoamyl acetate odor stimulation was presented either unilaterally through tubes inserted into the external nares, or bilaterally during unilateral olfactory bulb lidocaine infusions. Olfactory bulb m...
متن کاملComparison of odor receptive field plasticity in the rat olfactory bulb and anterior piriform cortex.
Recent work in the anterior piriform cortex (aPCX) has demonstrated that cortical odor receptive fields are highly dynamic, showing rapid changes of both firing rate and temporal patterning within relatively few inhalations of an odor, despite relatively maintained, patterned input from olfactory bulb mitral/tufted cells. The present experiment examined the precision (odor-specificity) of this ...
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 کاملReceptive Fields in Cat Striate Cortex
In the central nervous system the visual pathway from retina to striate cortex provides an opportunity to observe and compare single unit responses at several distinct levels. Patterns of light stimuli most effective in influencing units at one level may no longer be the most effective at the next. From differences in responses at successive stages in the pathway one may hope to gain some under...
