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!

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!
