To live and learn: making memories has to be a speedy business

The brain is plastic – adapting to the hundreds of experiences in our daily lives by reorganizing pathways and making new connections between nerve cells. This plasticity requires that memories of new information and experiences are formed fast. So fast that the body has a special mechanism, unique to nerve cells, that enables memories to be made rapidly. Continue reading

Kurt Haas discovers master regulator of brain plasticity

Synaptic plasticity, or the ability of neurons to form, strengthen, or weaken connections with each other, has long been studied as the basis for learning and memory. While the cellular processes and biological mechanisms involved are complex, much progress has been made at the Brain Research Centre and other research institutes around the world towards understanding this dynamic brain process.

Researchers demonstrate the key role played by a protein in learning and memory

Learning and remembering are based on molecular mechanisms that are still poorly understood. According to some experts, information is stored in the brain and reactivated as required by strengthening synapses that link neurons together. The strength of these links depends on the abundance of neurotransmitters, receptors, and of all other molecules involved in chemical transmission of information. Continue reading

Neuro researchers sharpen our understanding of memories

Jean-Claude Lacaille
May 2, 2012 – Scientists now have a better understanding of how precise memories are formed thanks to research led by Prof. Jean-Claude Lacaille of the University of Montreal’s Department of Physiology. “In terms of human applications, these findings could help us to better understand memory impairments in neurodegenerative disorders like Alzheimer’s disease,” Lacaille said. The study looks at the cells in our brains, or neurons, and how they work together as a group to form memories. Continue reading
