Polina Olegovna Anikeeva(born 1982) is a Russian-born Americanmaterials scientistwho is a Professor of Material Science & Engineering as well as Brain & Cognitive Sciences at theMassachusetts Institute of Technology(MIT).[3][1][4]She also holds faculty appointments in the McGovern Institute for Brain Research and Research Laboratory of Electronics at MIT. Her research is centered on developing tools for studying the underlying molecular and cellular bases of behavior and neurological diseases. She was awarded the 2018Vilcek FoundationPrize for Creative Promise in Biomedical Science, the 2020 MacVicar Faculty Fellowship at MIT, and in 2015 was named a MIT Technology Review Innovator Under 35.

Early life and education

[edit]

Anikeeva was born inSaint Petersburg,Russia(then Leningrad, Soviet Union), the daughter of mechanical engineers.[5]At 12, Anikeeva was admitted to thePhysical-Technical High School.[6]She studied biophysics atSt. Petersburg State Polytechnic University,where she worked under the guidance ofTatiana Birshtein,[7]a polymer physicist at the Institute of Macromolecular Compounds of the Russian Academy of Sciences. During her undergraduate studies she also completed an exchange program atETH Zurich[3]where she learned to analyze the structure of proteins using nuclear magnetic resonance spectroscopy.[5]

After graduating in 2003, Anikeeva spent a year working in the Physical Chemistry Division atLos Alamos National Laboratorywhere she developed photovoltaic cells based on quantum dots (QDs).[8]In 2004, she enrolled in the Materials Science and Engineering Ph.D. program at MIT and joinedVladimir Bulović's laboratory oforganic electronics.[2]While a graduate student, she was the lead author on a seminal paper[9]that reported a method for generating QD light-emitting devices with electroluminescence tunable over the visible spectrum (460 nm to 650 nm). Her doctoral research was commercialized by the display industry, and acquired by a manufacturer that eventually became part ofSamsung.[10]

Research and career

[edit]

Anikeeva moved to Stanford University and was appointed toKarl Deisseroth's neuroscience laboratory as a postdoctoral scholar, where she created devices for optical stimulation and recording from brain circuits.[11]The Deisseroth laboratory pioneeredOptogenetics,a technique that utilizes light-sensitive ion channels such asChannelrhodopsinsto modulate neuronal activity. Anikeeva worked on combining tetrodes, electronic modalities used to record neuronal activity, with optical waveguides[12]to create optetrodes. In Deisseroth’s lab, Anikeeva found a way to improve upon the fiber-optic probes they were using. Through her version, she incorporated multiple electrodes, allowing them to better capture neuronal signals.[13]These optoelectronic devices could be used to record the electrical activity invoked by light delivered through the waveguide.[14][15][16]

Anikeeva returned toCambridge, Massachusettsas an AMAX Career Development Assistant Professor at MIT in 2011.[17]The Anikeeva laboratory, which is also referred to as Bioelectronics@MIT, engineers tools to study and control the nervous system.[18][19]By pursuing wireless technologies, Anikeeva's group has demonstrated techniques that use magnetic fields and injected nanoparticles to activate cells within mice brains.[5]

Anikeeva's work emphasizes probing the brain with softer materials while integrating several functions into one device. Her research centers around creating a much less invasive way of stimulating brain cells. Her laboratory has two primary research priorities. The first is using the thermal drawing technique, a process originally developed for applications such as fiber optics and textiles, to create flexiblepolymer,fiber-based neural interfaces.[14][15][20][16]In 2015, Anikeeva and co-workers first reported these flexible neural interfaces, which are also referred to as neural probes, and demonstrated that they could combine optical, electronic, and microfluidic modalities into a single implantable device for chronic interrogation of the nervous system.[14]These fibers are a more advanced and scalable technology than their optetrode precursors. Since then, Anikeeva and her students have created more advanced neural interfaces that can be customized at their NeuroBionics lab[21]and include materials such as photoresists[22]and hydrogels.[23]

Anikeeva's second main research theme is using magnetic fields to wirelessly modulate neuronal activity. Unlike light, which has a limited penetration depth in biological tissues due to attenuation, weak alternating magnetic fields (AMFs) have minimal coupling to biological tissues due to tissues' low conductivity and negligible magnetic permeability.[24]In 2015, Anikeeva and her students demonstrated in a key paper published inScience[25]that magneto-thermal stimulation with magnetic nanomaterials could be used for wireless deep brain stimulation. Follow up studies from the Anikeeva laboratory then extended this concept to stimulate mechanosensitive channels.[26]Anikeeva and her colleagues have also shown that these magnetic nanomaterials can additionally be used to trigger drug delivery,[27]hormone release,[28]and for stimulatingacid-sensing ion channels.[24]

Current research

[edit]

Anikeeva's recent work explores the brain-gut interface, advancing the fundamental neuroscience of brain-organ communication.[5]While her previous work centered around the central nervous system, Anikeeva is now exploring communication from the peripheral nervous system.

Particularly intrigued by the signals exchanged between the brain and nervous system, Anikeeva initially focused on understanding how sensory cells in the gut influence the brain and body through neuronal communication and hormone release.[29]Now, Anikeeva emphasizes the reciprocal communication between the body and brain involving their two-way interaction. Her team continues to regulate and explore functions that had previously been attributed solely to central neural control.[29]

In May 2023, Anikeeva co-founded and became the scientific advisor of the NeuroBionics lab.[30]Her first device contains 6 tungsten microelectrodes, an optical channel for optogenetics and fiber photometry, and a fluidic channel.[31]

During the BrainMind Special Forum on Neuromodulation + BCI + AI in June 2024,[32]Anikeeva explained how traditional sharp materials are dangerous when injected into the brain’s soft tissues. To address this, Anikeeva’s team draws inspiration from the flexibility and signal transmission capabilities of natural nerves.[32]Anikeeva's team is already designing stiff fibers that could be threaded into the brain, as well as more delicate, rubbery fibers that are still sturdy enough for the digestive track.[33]Much of Anikeeva's recent work emphasizes the interconnectedness of the brain and body, noting that many neurological conditions also involve gastrointestinal (GI) symptoms. However, developing therapies concerning these disorders has proven a recent challenge as it is difficult to deliver them across the blood-brain barrier.[34]Anikeeva's recent work on magnetic stimulation has raised the possibility to avoid the barrier altogether. Her future projects aim to investigate the interplay between digestive health and these neurological conditions.[33]

TEDx talks

[edit]

Anikeeva has given TEDx talks where she discusses the technologies invented in her laboratory and neural interfaces more broadly.

  • "Rethinking the Brain Machine Interface," TEDxCambridge (2015).[35]She discussed her work on neuroprosthetics and brain-machine interfaces, emphasizing her approach to match the brain's mechanical complexity through minimally-invasive materials.
  • "Why You Shouldn't Upload Your Brain to a Computer," TEDxCambridgeSalon (2018).[36]She explained the distinctions between the human brain and artificial intelligence, proposing them to collaborate.
