Dr Wendy Suzuki is a Neuroscientist and Professor at New York
University whose lab was the first to capture neurons firing as
new memories are born. Her TED talk has over 65 million views,
and she's the author of Good Anxiety and Healthy Brain, Happy
Life.

structure that builds your internal model of reality, imagines
futures you've never lived, and may be the engine that constructs
your sense of self.


Expect to learn how place cells and grid cells map your world
inside your skull, why people without a hippocampus can't imagine
a tropical beach, how memories become models and models become
selves, what the default mode network reveals about
consciousness, how exercise physically grows new brain cells even
into your 90s, why the boundary between memory and imagination is
far blurrier than you think, and much more…
