Sentences with phrase «antennal lobe»

Yu, D., Davis, R.L. «Functional imaging of antennal lobe neurons in Drosophila with synapot - pHluorin.»

The neuron pathways activated in the moths were tracked by inserting a 16 - channel electrode into the moth's antennal lobe, where the moth processes odor information from its antennae.

Using microelectrodes, the researchers recorded the electrical activity of pheromone - sensitive interneurons in male American cockroaches that relay signals of female - producing sex pheromones in the antennal lobe (functional homolog to the mammalian olfactory bulb) to higher - order centers.

Olfactory glomeruli, spherical structures in the antennal lobe of insects, are considered the primary subunits of the olfactory center.

Comparing behavior (feeding or egg - laying) to the activity patterns in the antennal lobe reveals that activity in specific brain areas correlates with one of the behaviors.

A team of researchers from the Department of Evolutionary Neuroethology, led by Sonja Bisch - Knaden, has investigated whether neural activity patterns linked to either feeding or egg - laying behavior can already be observed in the antennal lobe, which is the first processing level of scents in the insect brain.

Because a habitat may contain related moth species that use the same flowers as nectar sources but different host plants to lay their eggs, the researchers would like to investigate whether odors that provide olfactory cues to identify the best oviposition sites activate similar areas in the antennal lobe of these moths, or whether the functional atlas of the brain is different in each species.

«By using diagnostic odors to stimulate each single moth in our test series, we established a functional atlas of the antennal lobe.

Moths find flowers by building an odor map in their antennal lobes.

MB, mushroom bodies; AL, antennal lobes; and SOG, subesophageal ganglion.

Thus, we concluded that Acks could be utilized as a marker of neural activity that occurred 30 to 60 min before in the brains of Japanese honeybees, although we could not detect the spotted signal in the antennal lobes (ALs, primary olfactory center), suggesting that Acks, like kakusei, is not useful for detecting neural activity in the ALs (data not shown).
