Happy (Socially Distanced) October from the KM Lab!

Congratulations to Dr. Angela Nietz and all the authors on the publication of

"Selective loss of the GABA Aα1 subunit from Purkinje cells is sufficient to induce a tremor phenotype" in Journal of Neurophysiology.

Congratulations to Dr. Zachary Zeidler on the successful defense of his thesis.

Sad to see him go, but happy to announce that Zach is now Dr. Zeidler!

The final portion of his thesis just came out in Journal of Neuroscience.

Zach is off to UCLA to do a postdoc in the lab of Laura DeNardo.

Congratulations to Jessica Froula on receiving an MnDRIVE Brain Conditions Fellowship for 2020-2021!

We're a little late announcing this one thanks to COVID, but no less excited about it.

Well done Jessica!

Stay tuned for all the exciting science Jessica is working on.

Bethany Stieve awarded MnDRIVE Informatics Fellowship -- Dec, 2019

Congratulations to Bethany on being awarded an MnDRIVE Informatics Fellowship!

Even a single 50ms light pulse to excite excitatory fastigial neurons can stop seizures! (aka: Martha's paper is published!) -- Dec, 2019

Martha's paper has been published (available now in pretty pdf form!) in JPhysiol. Key take away in brief:

On-demand excitation of excitatory neurons in the cerebellar fastigial nucleus provides robust inhibition of hippocampal seizures in the IHKA mouse model. Inhibition of the same cells does nothing.

Sinem's Visit Comes to an end -- Nov 30, 2019

It was great havin Muhsine Sinem Ethemoglu Sari in the lab the past few weeks. Her enthusiasm for science was terrific and will be missed. Best wishes!

Zoe's paper accepted & published at eLIFE. -- Oct 14, 2019

Abstract

The hippocampus, a brain region important for spatial navigation and episodic memory, benefits from a rich diversity of neuronal cell-types. Through the use of an intersectional genetic viral vector approach in mice, we report novel hippocampal neurons which we refer to as LINCs, as they are long-range inhibitory neuronal nitric oxide synthase (nNOS)-expressing cells. LINCs project to several extrahippocampal regions including the tenia tecta, diagonal band, and retromammillary nucleus, but also broadly target local CA1 cells. LINCs are thus both interneurons and projection neurons. LINCs display regular spiking non-pyramidal firing patterns, are primarily located in the stratum oriens or pyramidale, have sparsely spiny dendrites, and do not typically express somatostatin, VIP, or the muscarinic acetylcholine receptor M2. We further demonstrate that LINCs can strongly influence hippocampal function and oscillations, including interregional coherence. Identification and characterization of these novel cells advances our basic understanding of both hippocampal circuitry and neuronal diversity.

Dr. Christenson Wick — Aug 5, 2019 2:54:21 PM

A great big congratulations to Dr. Zoe Christenson Wick on successfully defending her dissertation! She's off to do a postdoc in the lab of Tristan Shuman at Mt. Sinai, and will be missed.

Thank you to all her family and friends for coming out to support her, and thank you to all of her committee members that helped guide us through the process.
