The Spring 2022 CBMM Research Meetings will be hosted in a hybrid format. Please see the information included below regarding attending the event either in-person or remotely via Zoom connection

Please note, MIT is requiring that all attendees, including MIT COVIDpass users, sign-in to the event prior to entering the auditorium.

Abstract: We can computationally approximate a visual object's identity from the distributed neural activity patterns across a series of hierarchically connected brain areas (e.g., V4, IT) in the primate ventral stream. However, testing whether these circuits indeed play a causal role requires targeted neural perturbation strategies that enable discrimination amongst competing models. Here we probed the role of macaque V4 and its primary feedforward target, the inferior temporal (IT) cortex, during object recognition. We combined DREADDs-based chemogenetic inhibition of V4 neurons with large-scale electrophysiology in V4 and IT while simultaneously measuring the monkeys' image-by-image object recognition behavior. Our results provide causal evidence linking the ventral stream hierarchy with core object recognition behavior. Also, in addition, to providing a “yes” vs. “no” answer to the involvement of a brain area in a behavior, we demonstrate how our approach allows us to use direct causal perturbation data to discriminate amongst competing mechanistic brain models.​

Guidance for attending in-person:

MIT attendees:
MIT attendees will need to be registered via the MIT COVIDpass system to have access to MIT Building 46.
Please visit URL https://covidpass-mit-edu.ezproxyberklee.flo.org/ for more information regarding MIT COVIDpass.

Non-MIT attendees:

MIT is currently welcoming visitors to attend talks in person. All visitors to the MIT campus are required to follow MIT COVID19 protocols, see URL https://now-mit-edu.ezproxyberklee.flo.org/policies/campus-access-and-visitors/.  Specifically, visitors are required to wear a face-covering/mask while indoors and use the new MIT TIM Ticket system for accessing MIT buildings. Per MIT’s event policy, use of the Tim Tickets system is required for all indoor events; for information about this and other current MIT policies, visit MIT Now.

To access MIT Bldg. 46 with a TIM Ticket, please enter the building via the McGovern/Main Street entrance - 524 Main Street (on GPS). This entrance is equipped with a QR reader that can read the TIM Ticket. A map of the location of, and an image of, this entrance is available at URL: https://mcgovern-mit-edu.ezproxyberklee.flo.org/contact-us/

General TIM Ticket information:

A visitor may use a Tim Ticket to access Bldg. 46 any time between 6 a.m. and 6 p.m., M-F

A Tim Ticket is a QR code that serves as a visitor pass. A Tim Ticket, named for MIT’s mascot, Tim the Beaver, is the equivalent of giving someone your key to unlock a building door, without actually giving up your keys.

This system allows MIT to collect basic information about visitors entering MIT buildings while providing MIT hosts a convenient way to invite visitors to safely access our campus.

Information collected by the TIM Ticket:

• Name
• Phone number
• Email address
• COVID-19 vaccination status (i.e., whether fully vaccinated or exempt)
• Symptom status and wellness information for the day of visit

The Tim Tickets system can be accessed by invited guests through the MIT Tim Tickets mobile application (available for iOS 13+ or Android 7+) or on the web at visitors.mit.edu.

Visitors must acknowledge and agree to terms for campus access, confirm basic contact information, and submit a brief attestation about health and vaccination status. Visitors should complete these steps at least 30 minutes before scanning into an MIT building.
