In this study the authors investigated molecular pathways associated with memory formation. They used the behavioral genetics approach to identify genetic variations related to memory performance. An additional fMRI-study was conducted to validate their genetic findings as well as to capture brain activity related to the genotype. Out of 336 healthy subjects that underwent an […]

Molecular computer models enhance learning and memory
Posted on behalf of Benjamin Paffhausen: The authors studied long term sensitization of the withdrawal reflex in Aplysia, which is an example of long term memory (LTM). Previous findings suggested that activation of protein kinase A (PKA) and extracellular signal regulated kinase (ERK) lead to long term facilitation (LTF), a form of LTM. PKA and […]
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 […]
Are autism and schizophrenia diametric extremes?
In this focus paper in Behavioral and Brain Sciences, Crespi and Badcock argue that the psychiatric disorders autism and schizophrenia are opposite ends of a psychological spectrum. They claim that the natural variations in several factors such as sense of self, gaze, agency, social cognition, local versus global processing and others creates a spectrum at […]
