Temporal coding in the gustatory system.
Early investigations of temporal coding in the gustatory system showed that the time course of responses in some neurons showed systematic differences across the various classes of taste stimuli, implying that the temporal characteristics of a response can convey information about a taste stimulus. Studies of temporal coding in the gustatory system have grappled with several unique methodologic...
متن کاملPostnatal development of spatial coding in the gravity sensing system
The critical maturation time of central otolith neurons in processing spatial orientations was examined in Sprague-Dawley rats. With the use of immuno-hybridization histochemical methods, we observed c-fos expression in vestibular nuclear neurons responding to transverse movement on the horizontal plane as early as P7 and those to antero-posterior stimulation as early as P9. In the inferior oli...
متن کاملMechanisms of Gustatory Coding in Spodoptera Littoralis
Adult Lepidoptera use their antennae to probe their distant and proximate environment with sensory organs which detect volatile and contact chemicals. In this work, we have investigated the role and the sensitivity of antennal contact chemoreceptors of Spodoptera littoralis. Adults of both sexes have long and filiform antennae composed of about 70 flagellomeres. Each flagellomere bears six tast...
متن کاملCoding and Plasticity in the Mammalian Thermosensory System
Perception of the thermal environment begins with the activation of peripheral thermosensory neurons innervating the body surface. To understand how temperature is represented in vivo, we used genetically encoded calcium indicators to measure temperature-evoked responses in hundreds of neurons across the trigeminal ganglion. Our results show how warm, hot, and cold stimuli are represented by di...
