Beauty is in the eye of the machine

Perspective article by Mengmi Zhang. Nature Human Behavior (2021).

Ansel Adams said, “There are no rules for good photographs, there are only good photographs.” Is it possible to predict our fickle and subjective appraisal of ‘aesthetically pleasing’ visual art? Iigaya et al. used an artificial intelligence approach to show how human aesthetic preference can be partially explained as an integration of hierarchical constituent image features.

He Tia… Systems Club. He Tian: All-optical electrophysiology reveals interneuron network dynamics in vivo January 13, 2022 5:15 pm - 6:15 pm SysClub is back this Thursday - 1/13/21. He Tian from the Cohen lab will be presenting her talk: “All-optical electrophysiology reveals interneuron network dynamics in vivo.” Here is a description to the talk and link to a pre-print of some of the work: “All-optical electrophysiology can be a powerful tool for studying neural dynamics in vivo, as it offers the ability to image and perturb membrane voltage in multiple cells simultaneously. The “Optopatch” constructs combine a red-shifted archaerhodopsin (Arch)-derived genetically encoded voltage indicator (GEVI) with a blue-shifted channelrhodopsin actuator (ChR). We used a video-based pooled screen to evolve Arch-derived GEVIs with improved signal-to-noise ratio (QuasAr6a) and kinetics (QuasAr6b). By combining optogenetic stimulation of individual cells with high-precision voltage imaging in neighboring cells, we mapped inhibitory and gap junction-mediated connections, in vivo. Optogenetic activation of a single NDNF-expressing neuron in visual cortex Layer 1 significantly suppressed the spike rate in some neighboring NDNF interneurons. Hippocampal PV cells showed near-synchronous spikes across multiple cells at a frequency significantly above what one would expect from independent spiking, suggesting that collective inhibitory spikes may play an important signaling role in vivo. By stimulating individual cells and recording from neighbors, we quantified gap junction coupling strengths. Together, these results demonstrate powerful new tools for all-optical microcircuit dissection in live mice.” Due to current Harvard event restrictions, we will only be holding this talk over Zoom. Please join us at 12:15pm in this meeting room. See more details •	14	15	16
