Dendrites are branch-like structures that extend from the cell body and collect information from other neurons.The cell body contains the nucleus, which houses the genetic blueprint that directs and regulates the cell’s activities.Most neurons have three basic parts: a cell body, multiple dendrites, and an axon. Alzheimer’s disease disrupts this communication among neurons, resulting in loss of function and cell death. They send messages between different parts of the brain, and from the brain to the muscles and organs of the body. As with all scientific research, there is also a risk of publication bias.The healthy human brain contains tens of billions of neurons-specialized cells that process and transmit information via electrical and chemical signals. These results are promising, but more research is needed to determine the connection between improved assessment scores and everyday tasks in participants' lives.įuture research should address the risk of inadvertent experimenter bias and the risk of attrition bias in this study, as both the Lumosity and crossword groups had approximately 50% attrition rate.

In it, half of the 4,715 participants who completed the study trained five days per week, for fifteen minutes each day on Lumosity while the other half did online crossword puzzles as an active control.Īfter 10 weeks, Lumosity users improved more than the control group on our assessments of working memory, short term memory, processing speed, problem solving, fluid reasoning, and overall cognitive function. Lumos Labs conducted a randomized study of Lumosity brain training and published the results in a peer-reviewed research journal.
