September 2019

Our new paper on the synaptic organization of layer 6a is published in Cell Reports. WE show that interlaminar parvalbumin-positive (PV) inhibitory interneurons are located in upper layer 6a and receive input from VPM-only projecting layer 6 corticothalamic neurons, corticocortical neurons and thalamocortical afferents. Lower L6a, in contrast, contains local PV interneurons. Corticocortical neurons have a higher probability of connection onto these local PV interneurons than do VPM/POm-projecting layer 6 corticothalamic neurons and their VPM/POm-projecting layer 6 corticothalamic neurons depress. The overall synaptic organization suggests that inhibition is a primary intracortical output of upper layer 6a. Congratulations Jaclyn, Chanel, Kihwan, Juhyun, Maxime, Su-Jeong and Aaron!

August 2017

Juhyun's paper showing that increases in neuronal excitability are not restricted to cortical cell types that degenerate  in Amyotrophic Lateral Sclerosis (ALS) was just published in the Journal of Neuroscience. These findings suggest that therapies for ALS may need to be tailored for different cell types and stages of disease. This work was a collaboration with the Hughes Lab at the University of Colorado, Ashwin Shetty and Paola Arlotta at Harvard, and the Bergles and Goff labs at Johns Hopkins. Here is the link: DOI: 10.1523/JNEUROSCI.0811-17.2017

The Brown and Goff laboratories receive a grant from the National Science Foundation to determine  cell-type specific gene expression differences induced by experience-dependent plasticity.  Experiences in our environment affect the activity of genes expressed in neurons and lead to changes in brain circuits.  How different cell types in the brain differ in their responses to changes in incoming sensory input is the focus of this study.

Congratulations to all who contributed to the grant!
