Recently a study from Ryszard Maleszka’s Lab demonstrates that DNA methylation does play a role in the acquisition of memory and mediates the resistance of this memory to extinction in honeybees (Lockett et al 2010). Now the group of Paul Szyszka in Konstanz provides additional information about the role of DNA methylation in the formation […]

Coincident firing of neurons can specify a synapse for later modulation
Yet another fascinating Nature article from the research group around Gilles Laurent. This article is built around the mechanisms underlying associative learning and plasticity in the mushroom bodies in insects. The area is known to be crucial for associative learning of odors and contains up to hundreds of thousands of neurons called Kenyon cells. Here […]
Effects of appetitive and nonappetitive odors on feeding behavior and on level of biogenic amines
A short communication was published in November 2011 (Neurobiologie) based on a study from 2005 (Journal of Neuroscience). In the blowfly Phormia regina, the authors investigated the effect on PER when flies are (pre-) exposed to odors. They found that feeding threshold to sugar increased in the presence of the repellent D-limonene and decreased in […]
