Link between what we see and how we remember 'breaks' as we get older
Forgetfulness and age-related memory lapses are a common complaint among older adults, but what is still not understood is what causes these changes. Recent research published by scientists at Baycrest's Rotman Research Institute (RRI) brings us a step closer to uncovering the answer, which could help with distinguishing signs of dementia earlier.

Can tiny doses of magic mushrooms unlock creativity?
The use of minute doses of magic mushrooms and truffles containing psychedelic substances could induce a state of unconstrained thought that may produce more new, creative ideas. 'Microdosing' in this way may allow people to experience the creative benefits of psychedelic drugs without the risk of the so-called 'bad trips' that often come with high doses of such substances.

Early changes to synapse gene regulation may cause Alzheimer's disease
TMDU-led Japanese research revealed a role for splicing proteins in the pathology of Alzheimer's disease. Increased phosphorylation of the SRRM2 protein, seen in AD mouse models and human patients, was found to block its transport to the nucleus. This reduced levels of the PQBP1 protein, causing abnormal changes to the splicing of synapse genes and cognitive decline. These phenotypes were reversed by restoring PQBP1 function, suggesting a possible future treatment for AD. (2018-10-12)

How the grid cell system of the brain maps mental spaces
How exactly the grid cell system works in the human brain, and in particular with which temporal dynamics, has until now been speculation. A much-discussed possibility is that the signals from these cells create maps of 'cognitive spaces' in which humans mentally organize and store the complexities of their internal and external environments. A European-American team of scientists has now been able to demonstrate, with electrophysiological evidence, the existence of grid-like activity in the human brain. (2018-10-12)
