ION Seminar Series

 

Welcome to the 2021-2022 Seminar Series!  This academic year will host a series of virtual and in person seminars with live, remote Zoom access. Details for upcoming seminars will be shared here on the ION website as well as through our ION mailing lists.  Links to virtual seminars will be advertised only through the ION mailing list and those not on the list can request access by contacting Jenna Penny at seminars @ uoneuro.uoregon.edu.  ION Seminars are open to the University of Oregon community and in person attendance will be limited based on classroom capacity on a first-come, first-serve basis.  In person seminars will be held in Willamette 110 at 4 PM PT where both attendees and speakers are required to follow University of Oregon guidelines for preventing the spread of COVID-19.  Please visit coronavirus.uoregon.edu for more information.

Trainee Discussion Session following the seminar ending at 2:00 p.m. - Please RSVP with Michael Sidikpramana

To understand how cortical circuits generate complex behavior, it is crucial to investigate the cell types that comprise them. Functional differences across pyramidal neuron (PyN) types have been observed in sensory and frontal cortex, but it is not known whether these differences are the rule across all cortical areas or if different PyN types mostly follow the same cortex-wide dynamics. We used genetic and retrograde labeling to target pyramidal tract (PT), intratelencephalic (IT) and corticostriatal projection neurons and measured their cortex-wide activity. Each PyN type drove unique neural dynamics at a cortex-wide and within-area scale. Cortical activity and optogenetic inactivation during an auditory discrimination task also revealed distinct functional roles: all PyNs in parietal cortex were recruited during sensory stimulation but, surprisingly, PT neurons were most important for perception. In frontal cortex, all PyNs were required for accurate choices but showed distinct choice-tuning. Our results reveal that rich, cell-type-specific cortical dynamics shape perceptual decisions.   Learn more
