Protein kinase Mζ (PKMζ) is thought to be essential for the maintenance of long-term potentiation (LTP) and memory, but two new studies show that mice lacking PKMζ have normal memories and can undergo normal LTP, casting doubt on the importance of PKMζ for these processes.- d! i: j/ A+ e2 E7 v( B' ?

The distal axon and soma of a neuron may be a considerable distance apart, but they are still required to efficiently communicate with each other. In this Review, Harrington and Ginty examine how long-distance retrograde growth factor signalling is achieved between these compartments and its functions.

This Analysis article presents and tests a possible taxonomical solution for classifying cortical GABAergic interneurons based on a web-based interactive system that allows experts to classify neurons with pre-determined morphological criteria.$ u( T( J6 d% P! w5 b1 ~

Here, Wittmann explores why this has been the case and presents recent theoretical developments and empirical findings indicating that 'climbing' neural activity has a central role in time perception."
