1. Memory Consolidation and the VOR
Charles D. Kassardjian, Yao-Fang Tan, Ji-Yeon J. Chung, Raquel Heskin, Michael J. Peterson, and Dianne M. Broussard

The consolidation of memories may involve sites remote from where they form. This week, Kassardjian et al. explore motor memory consolidation using the cat vestibulo-ocular reflex (VOR), which holds the visual world steady during rapid head movements. The authors suggest that after initial memory formation, the consolidation phase involves a site outside of the cerebellum.

2. Parkin and One of Its Substrates, p38
Han Seok Ko, Rainer von Coelln, Sathya R. Sriram, Seong Who Kim, Kenny K. K. Chung, Olga Pletnikova, Juan Troncoso, Brett Johnson, Roya Saffary, Eyleen L. Goh, Hongjun Song, Bum-Joon Park, Min Jung Kim, Sunghoon Kim, Valina L. Dawson, and Ted M. Dawson

Oneof the familial forms of Parkinson's disease (PD), autosomal recessive juvenile parkinsonism (AR-JP), arises from a mutation in parkin, a ubiquitin ligase that normally targets proteins for degradation. This week, Ko et al. make a case that accumulation of a parkin substrate could be important in the pathogenesis of PD.

Adult neurogenesis essential for sleep-induced memory consolidation in mice
Adult neurogenesis, in which new neurons are generated within the hippocampus in the fully developed adult brain, occurs in mice -- but how new neurons are functionally integrated into existing brain circuitry has remained largely unknown.

Previously claimed memory boosting font 'Sans Forgetica' does not actually boost memory
It was previously claimed that the font Sans Forgetica could enhance people's memory for information, however researchers from the University of Warwick and the University of Waikato, New Zealand, have found after carrying out numerous experiments that the font does not enhance memory.

BIN1 deficit impairs brain cell communication, memory consolidation
A new study has discovered that a lack of neuronal protein BIN1 leads to a defect in the transmission of chemical messages that activate brain cell communication allowing us to think, remember and behave.

Memory boost with just one look

VR is not suited to visual memory?!
Toyohashi university of technology researcher and a research team at Tokyo Denki University have found that virtual reality (VR) may interfere with visual memory.

The genetic signature of memory
Despite their importance in memory, the human cortex and subcortex display a distinct collection of 'gene signatures.' The work recently published in eNeuro increases our understanding of how the brain creates memories and identifies potential genes for further investigation.

Identified a neural mechanism involved in the creation and consolidation of memories
The memory of specific episodes is the base of autobiographical memory, but we do not know how the brain structures the experience to remember it in the long run.
