Scientists Identify Crucial Mechanism for Maintaining Neuronal Identity in the Brain

A team of researchers from the Institute for Neurosciences, a joint center of the Spanish National Research Council (CSIC) and the Miguel Hernández University (UMH) of Elche, in collaboration with researchers from Columbia University (New York, USA), has identified a mechanism that regulates the production of two different proteins from the same gene.

Dendritic Spine Clusters Physically Link Memories Formed Close in Time

According to a recent study, the reason why memories from the same day seem connected while events from weeks apart feel separate is as follows: Human brains use dendrites, which are spiny extensions of neurons, rather than the cell bodies to physically connect memories that happen in close succession.
