SummaryThe functional organization of olfaction and taste are briefly discussed in morphological, physiological, biochemical and behavioural terms. Olfaction in animals serves often for long range navigational purposes whereas taste acts as a close up “last moment food checking system”. Special attention is given to the coding problems in both systems. In taste, the spatial coding mode is prevalent. In olfaction a very complexe coding system exists, which used temporal as well as spatial means… Expand

Nature appears to have achieved a functional differentiation between different pacemaker neurones by altering their response to at least one or two of the PFK and FDPase effectors. Expand


Untersuchungen über die Geruchswahrnehmung und das Geruchsgedächtnis des Goldfisches
Large goldfish have been trained to recognize Cumarin as a signal for approach to the feeding place by means of a newly developed graphic method, and it is suggested that these movements serve as multiple measure of the direction of the odor gradients. Expand
Erregungsmuster einzelner Fasern des Tractus olfactorius lateralis des Fisches bei Reizung mit verschiedenen Geruchsstoffen
Olfactory adaptation to an odor is suppressed during mechanical stimulation of the mucosa, which may suggest a mechanism corresponding to “sniffling” of mamals helping the fish to localize the source of food. Expand
Histologische, funktionelle und spezifische Regeneration nach Durchtrennung der Fila olfactoria beim Goldfisch (Carassius auratus)
Higher concentrations of all substances used for odour training were capable of exciting the taste receptors or other struktures outside the olfactory mucosa, however, were below the thresholds for non-olfactory perception. Expand
Ultrastructure of Taste Receptors
The taste buds have received nearly all the attention of morphologists and physiologists alike, and it is probable that the more specific and discriminating modalities of taste are served by these structures. Expand
Degeneration and Regeneration of Taste Buds
Comparable denervation studies have not been performed in urodeles (salamander or newt) and the morphology of the taste organ in anurans (frog) is, as will be discussed later, quite distinct from that of fish, urodele, or mammal. Expand

The present work arose from the observation that in the hedgehog the olfactory bulb and the pyriform lobe are large and easily accessible 'and show a well-defined electrical activity related to o aroma stimulation. Expand
The response pattern of taste fibres in the chorda tympani of the monkey.
The monkey seems to be the first animal investigated possessing taste fibres responding to sucrose which also respond to saccharine, and the least specific taste fibre in this animal seem to be those responding to water. Expand
The Electro-Olfactogram
It is generally agreed today that the impulse discharge in primary afferent fibres of sense organs is triggered by a local depolarization produced by the receptor cells. Beck (1899) was probably theExpand
These studies suggest that the cells within the taste bud, as well as the nerves, undergo considerable change with time, and Corresponding changes in function are considered. Expand
Measurement of Specific Anosmia
The objective of this work was to measure the quantitative deficiency of the specific anosmics, in comparison with normal Ss with respect to each odorant, for the definition of what is believed to be one of the “primary odors” of the sense of smell, the "sweaty" primary epitomized by isovaleric acid.
