Galen on the elements of olfactory sensation.
In different sources for the Galenic doetrine of smell there appear different elements in the nature of the sense of smell. What we shall suggest is that these accounts are as likely to vary because of varying emphasis as because of error in the copying of manuscripts. In the surviving works of Galen (AD 129 ?-I99) mention of the sense of smell and its objeets can be found in four places: (I) D...
متن کاملElectrophysiological measurements from a moth olfactory system.
Insect olfactory systems provide unique opportunities for recording odorant-induced responses in the forms of electroantennograms (EAG) and single sensillum recordings (SSR), which are summed responses from all odorant receptor neurons (ORNs) located on the antenna and from those housed in individual sensilla, respectively. These approaches have been exploited for getting a better understanding...
متن کاملElectrophysiological properties of frog olfactory supporting cells.
Cells, identified as supporting cells by Lucifer Yellow injection, were recorded from slices of frog olfactory epithelium using patch-clamp recordings. Cell-attached single-channel recordings indicated that the intracellular potential (IP) was -68 +/- 7 mV (n = 22) with 4 mM K+ in the bath ([K+]o). IP was -67 +/- 4 mV (n = 32) in whole-cell conditions with 100 mM KCl inside the cell, suggesting...
متن کاملAn electrophysiological survey of frog olfactory cilia.
Individual olfactory receptor neurons vary widely in their responses to odorants. Olfactory stimulus reception occurs in the cilia of the receptor neurons. Thus, the variability among individual neurons could in part be due to differences among the olfactory cilia. We have quantified the known conductance properties of each of 117 frog olfactory cilia. From a strictly qualitative viewpoint, the...
متن کاملElectrophysiological correlates of emotional processing in sensation seeking.
Previous studies have consistently reported a relationship between sensation seeking and emotional reactivity. However, little is known about the neural correlates and the time course of emotional processing in sensation seeking. The present study addressed these issues by recording event-related potentials (ERPs) during an emotional oddball task. Valence effect was significant at N2, P3 and LP...
