Congratulations to Nicole Alexander on her graduation from UT Austin!
Nicole completed her honors thesis, entitled “Characterizing Social Behavior in a Rat Model of Fragile X Syndrome”, for Special Departmental Honors in Biology. Nicole is headed to her first choice medical school, Baylor College of Medicine, this fall.
Congratulations to Nicole for her 2017 Undergraduate Research Forum Award!
Nicole Alexander won the CNS Award for Excellence in Neuroscience for her poster entitled “Characterizing social behavior in a novel rat model of Fragile X Syndrome”. Nicole’s research was supervised by Dr. Alexandra Mably.
Chenguang and Laura comment on an exciting new paper from the Ji Lab.
Chun-Ting Wu and colleagues found that place cells replay representations of locations to be avoided. You may read about their findings here:

Alex’s paper showing impaired stability and rhythmic modulation of place cells in a mouse model of Alzheimer’s disease is now out.
The study is published in the current issue of Hippocampus:
New paper about slow gamma rhythms in CA3 and dentate gyrus
The lab published a new study in Journal of Neurophysiology showing that slow gamma rhythms in CA3 are entrained by slow gamma activity in the dentate gyrus:

New paper relating fast gamma rhythms to encoding of new associative memories
The lab published a new study in eNeuro showing that fast gamma activity is enhanced as animals learn new associations between objects and places:

Memory Matters 2016
The lab had fun educating the public about brain rhythms at this year’s Memory Matters event. We measured participants’ EEGs as they practiced enhancing their alpha rhythms!
