Journal ArticleDOI
Classical conditioning of proboscis extension in honeybees (Apis mellifera).
TL;DR: In a first series of experiments, acquisition was found to be very rapid, both in massing and in spaced trials; its associative basis was established by differential conditioning and by an explicitly unpaired control procedure (which produced marked resistance to acquisition in subsequent paired training); and both extinction and spontaneous recovery in massed trials were demonstrated.
Journal ArticleDOI
Distribution of GABA-like immunoreactivity in the brain of the honeybee.
Sabine Schäfer,Gerd Bicker +1 more
TL;DR: The dense reactivity seen in the optic and antennal neuropiles implies that GABA is more important in mediating local rather than more distant neural interactions.
Journal ArticleDOI
Glutamate-like immunoreactivity in identified neuronal populations of insect nervous systems
TL;DR: The results suggest that Glu-LI can be used as a marker for detecting potential glutamatergic neurons in insects under the present conditions and suggests that insect central nervous systems may contain glutamatorgic neuronal pathways.
Journal ArticleDOI
Dopamine-like immunoreactivity in the brain and suboesophageal ganglion of the honeybee.
Sabine Schäfer,Vincent Rehder +1 more
TL;DR: The distribution of dopamine in the brain and suboesophageal ganglion of the honeybee Apis mellifera was investigated by means of immunocytochemistry with a well‐characterized antiserum against dopamine.
Journal ArticleDOI
Mushroom body feedback interneurones in the honeybee show GABA-like immunoreactivity
TL;DR: The distribution of the transmitter substance GABA was investigated in the mushroom body neuropile of the honeybee by means of immunohistochemistry and it was found that interneurones contained within the PCT exhibit GABA-like immunoreactivity and may function as negative feedback loop.
