A celebration of creativity and community at MITArtfinity is a new festival of the arts at MIT featuring 80 free performing and visual arts events, celebrating creativity and community at the Institute. Artfinity launches with the opening of the new Edward and Joyce Linde Music Building on February 15, 2025, continues with a concentration of events February 28-March 16, and culminates with the Eugene McDermott Award in the Arts public lecture by 2025 recipient artist and designer Es Devlin on May 1, 2025, and a concert by Grammy-winning rapper and Visiting Professor Lupe Fiasco on May 2, 2025. Artfinity embodies MIT’s commitment to creativity, community, and the intersection of art, science and technology. We invite you to join us in this celebration, explore the diverse events, and experience the innovative spirit that defines the arts at MIT.About the Artists Artfinity features the innovative work of MIT faculty, students, staff, and alumni, alongside guest artists from the Greater Boston area and beyond.About the Activities & Events All 80 events are open to the public, including dozens of concerts and performances plus an array of visual arts such as projections, films, installations, exhibitions, and augmented reality experiences, as well as lectures and workshops for attendees to participate in. With a wide range of visual and performing arts events open to all, Artfinity embodies MIT’s commitment to the arts and the intersection of art, science, and technology.About the Presenters Artfinity is an institute-sponsored event organized by the Office of the Arts at MIT with faculty leads Institute Professor of Music Marcus Thompson and Professor of Art, Culture and Technology Azra Akšamija. Departments, labs, centers, and student groups across MIT are presenting partners.Visit arts.mit.edu for more information about the arts at MIT.

Have some fun(nel) on a tunnel or sun(nel) walk! Join us for a 30-minute volunteer-led walk either through MIT’s famous tunnel system or around Killian Court. As the weather gets warmer, walk leaders may choose to take the group outside. Is the weather warm and you missed the start? Find the group on Killian Court and join in!Sun(nel) Walk Leaders will identify themselves by holding a white flag at the meeting location.Location details: Meet in the atrium by the staircase. [See image below]Prize Drawing: Attend a walk and scan a QR code from the walk leaders to be entered into a drawing for a getfit canvas boat tote bag at the end of the getfit challenge. The more walks you attend, the more entries you get. Winner will be drawn and notified at the end of April. Winner does not need to be a getfit participant.Disclaimer: Tunnel walks are led by volunteers. In the rare occasion when a volunteer isn’t able to make it, we will do our best to notify participants. In the event we are unable to notify participants and a walk leader does not show up, we encourage you to walk as much as you feel comfortable doing so. We recommend checking this calendar just before you head out.Getfit is a 12-week fitness challenge for the entire MIT community. These tunnel walks are open to the entire MIT community and you do not need to be a current getfit participant to join.

Talk Title: Establishing the neural foundations of physical intelligenceTalk Abstract: My research aims to understand the neural representations and computations that subserve physical intelligence—creatively and efficiently assembling dexterous interactions with the physical world to solve complex challenges. I study these neural computations with high-throughput electrophysiology in rich and flexible tasks performed via robotic manipulanda in virtual environments. Although we can associate behaviors with specific neural activity patterns through passive observation, identifying the precise mechanisms that shape these patterns necessitates causal intervention. By formalizing hypotheses about neural computations as dynamical systems, I directly test them using targeted optogenetic and electrical perturbations. Through this approach, I resolved fundamental questions about the motor cortex, identifying a low-dimensional dynamical system that governs neural activity during reaching movements and is contained within a neural subspace exhibiting a privileged causal relationship with behavior. Additionally, I have assembled a brain-wide spiking activity map in a dynamic foraging task, wherein future decisions rely on computations integrating past interactions with the environment, including the history of choices and rewards that shape the subjective value of presently available actions. I have devised a data-driven framework to reconstruct the dynamical systems that shape brain-wide neural activity and reveal the key dynamical structures that underlie specific cognitive computations. Looking forward, I will integrate these methods to study a novel, cognitively demanding physical construction task, establishing the precise neural computations that enable physical intelligence, multi-step planning, and compositional reasoning.This talk will not be live streamed

February 26, 2025 - July 17, 2025Hidden within MIT’s Distinctive Collections, many architectural elements from the earliest days of the Institute’s architecture program still survive as part of the Rotch Art Collection. Among the artworks that conservators salvaged was a set of striking windows of gypsum and stained-glass, dating to the late 18th- to 19th c. Ottoman Empire. This exhibition illuminates the life of these historic windows, tracing their refracted histories from Egypt to MIT, their ongoing conservation, and the cutting-edge research they still prompt.The Maihaugen Gallery (14N-130) is open Monday through Thursday, 10am - 4pm, excluding Institute holidays.

Date: Monday, April 14th at 10AMIn-person Location: 46-3189, McGovern Seminar RoomOn Zoom: https://mit.zoom.us/j/94586137096Title: Top-down and bottom-up interactions for cortical burstingAbstract: High-frequency burst firing occurs throughout the mammalian cortex in vivo, yet both the underlying mechanisms and functional roles of bursts are unclear. Burst firing in brain slices is strongly modulated by the activity of apical dendrites, which branch extensively in layer 1 (L1) and receive long-range inputs from higher-order cortical and thalamic areas. These properties suggest a powerful subcellular substrate by which single pyramidal neurons could multiplex bottom-up and top-down information via L1-independent tonic spikes and L1-dependent bursts, respectively, and have provided a basis for emerging theoretical models of cortical computation and learning. However, our understanding of burst firing and subcellular processing remains critically limited by a lack of evidence in awake animals. It is unclear whether burst firing a) is preferentially recruited by bottom-up versus top-down inputs, and b) requires apical dendritic engagement. To answer these questions, we performed high-density extracellular recordings in primary visual cortex of awake mice while presenting a battery of Gabor (bottom-up) and inverse (top-down) visual stimuli. We report widespread high-frequency bursts in L2/3 and L5 pyramidal neurons. Contrary to expectation, bursts exhibited extremely short response latencies, and were most strongly recruited by Gabor stimuli. We further tested the causal contribution(s) of apical dendrites to burst firing and top-down visual tuning via two optogenetic manipulations: direct L5 apical tuft inhibition and NDNF interneuron activation. Strikingly, L1 inhibition only modestly reduced the burst fraction, and did not differentially affect Gabor vs inverse responses. Taken together, these results challenge prevailing theories of apical dendritic involvement in burst spike generation and feedback visual tuning, and provide new biological constraints for future theoretical and experimental work.
