\begin{abstract}
Hi Reddit, my name is Seth Blackshaw and I'm a professor of neuroscience
at the Johns Hopkins University School of Medicine. My research focuses
on identifying the network of genes that controls how different cell
types in the hypothalamus are specified during embryonic development,
and on using these findings to both identify how specific cell types
regulate behavior and determine how they can be replaced in
neurodegenerative disease. I became interested in this work because I am
convinced that to understand how neural circuits work, we have to name
and catalog their basic components -- the thousands of different cell
types present in the brain. If we can figure out how these cell types
are made, we can then understand which behaviors they regulate and how
they do so. We study development of the hypothalamus because it is a
master regulatory center for many interesting and medically important
behaviors -- ranging from circadian timing to sleep to aggression. I
recently published a paper on Nature describing newly identified brain
cells in mice that play a major role in promoting sleep.. My team
observed that a specialized type of neuron that had never been found in
this area of the brain before appear to connect a part of the
hypothalamus, called the zona incerta, to areas of the brain that
control sleep and wakefulness. This discovery could lead to the
development of new therapies to help people with sleep disorders, like
insomnia and narcolepsy, which are caused by the dysfunction of similar
sleep-regulating neurons. I look forward to answering your questions at
1pm ET%
