Hughlings Jackson Lecture: Making Memories in Mice

Event

Montreal Neurological Institute 3801 rue University, Montreal, QC, H3A 2B4, CA

 

The Hughlings Jackson Lecture is the Neuro’s premier scientific lecture. The Hughlings Jackson Lecture honors the legacy of British neurologist John Hughlings Jackson (1835‐1911) who pioneered the
development of neurology as a medical specialty.

Speaker: Sheena Josselyn, PhD Senior Scientist, Hospital for Sick Children, Professor, University of Toronto, Canada

Talk Abstract:

Understanding how the brain uses information is a fundamental goal of neuroscience. Several human disorders (ranging from autism spectrum disorder to PTSD to Alzheimer’s disease) may stem from disrupted information processing. Therefore, this basic knowledge is not only critical for understanding normal brain function, but also vital for the development of new treatment strategies for these disorders. Memory may be defined as the retention over time of internal representations gained through experience, and the capacity to reconstruct these representations at later times. Long-lasting physical brain changes (‘engrams’) are thought to encode these internal representations. The concept of a physical memory trace likely originated in ancient Greece, although it wasn’t until 1904 that Richard Semon first coined the term ‘engram’. Despite its long history, finding a specific engram has been challenging, likely because an engram is encoded at multiple levels (epigenetic, synaptic, cell assembly). My lab is interested in understanding how specific neurons are recruited or allocated to an engram, and how neuronal membership in an engram may change over time or with new experience. Here I will describe both older and new unpublished data in our efforts to understand memories in mice.
