Perceptual decision making is formalized as the accumulation of (noisy) sensory evidence until a decision threshold is crossed. Much understanding has been gained from studies of monkey neurophysiology and human neuroimaging as well as by computational modeling but there are still fascinating open questions about mechanisms of perceptual decision making. Perceptual decisions can be made […]

Specific erasure of fear memory by disrupting reconsolidation
Merel Kindt and her team demonstrated that fear memory can be deleted in humans (Kindt et al. 2009). This was achieved by the oral administration of β-adrenergic receptor antagonist propranolol before the reactivation of memory. They propose that their strategy of disrupting the (re-) stabilization of a memory after retrieval (reconsolidation) could pave the way […]
The Role of experience in flight behaviour of Drosophila
This study illustrates the requirement of training and exercise in executing successful fine motor skills in the invertebrates.Fruit fly Drosophila groups reared and grown in two different fly chambers ,one allows free flight movement and other restricted flight movement were tested for various flight kinematics in free flight arena and tethered flight simulator.Overall performance of […]
Critical role for protein kinase A in the acquisition of gregarious behavior in the desert locust
Posted on behalf of Hans-Joachim Pflüger: In the article by Ott et al. the role of two protein kinases (PK) in the population density dependent transition from solitarious to gregarious animals is investigated. Only gregarious locusts form large swarms that are harmful for agriculture. The foraging gene product, a cGMP-dependent PK (PKG), implicated in foraging, […]
