שלום לבוגרינו,

נשמח להזמינכם להתרשם מקרוב מהמעבדה המרתקת לחקר המוח, קוגניציה וטכנולוגיה בראשות פרופסור אמיר עמדי .
הסיור יתקיים ביום ב' - 1.5 בבניין היזמות באוניברסיטת רייכמן בין השעות 18:00-19:30

**הסיור אינו כרוך בתשלום אך מספר המקומות מוגבל**

על מכון ברוך איבצר בקצה המזלג:

אחת ההתמקדויות הנוכחיות של המכון היא שימוש בטכנולוגיות רב-חושיות שפותחו במכון, כגון חוויות תלת מימדיות, טכנולוגיות לבישות ועוד להגברת הנוירו-וולנס ושיפור בריאות הנפש. בין מטרות המחקר והפיתוחים: שיפור שמיעה דרך טכנולוגיות מגע מרחבי, הפחתת חרדה, השראת רגיעה, הפחתת כאב כרוני ועוד.
בין היתר,המכון חוקר גם את הבסיס המוחי וההשפעות העצביות של כל החוויות והטכנולוגיות.

How to design an echolocating bat?

Abstract

Echolocating bats master the use of sound for sensing. Over decades of research, scientists have revealed many of the mechanisms underlying bat echolocation, but do we understand enough in order to build a bat? In my talk, I will discuss the current state of our understanding of how to apply bat-like bio-sonar in a bio-mimetic robotic-device. I will discuss controlling beam emission and reception, using the bat’s mouth and ears. I will discuss control strategies for translating sensing into movement and for flight guidance, and I will suggest solutions for dealing with interfering from other bats. I will present data collected on-board wild bats carrying microphones in the field and I will describe our recent attempts to develop an autonomous bat-like robotic vehicle and a swarming bat-like robotic drone. Finally, I will also discuss what we do not understand and which open questions are still awaiting to be solved.

Short Bio

Prof. Yossi Yovel is a full Professor and the head of the lab of NeuroEcology in the School of Zoology and the head of the Sagol School of Neuroscience at Tel Aviv University. He received a B.Sc. degree in Biology and another one in physics both from Tel Aviv University, an M.Sc. in Neuroscience from Tel-Aviv University and a Ph.D. in Biology and Machine Learning from the University of Tuebingen, Germany. He then completed two post-docs: one in the Weizmann Institute and one in the University of Chicago before joining Tel-Aviv University Faculty in 2011.

Prof. Yovel has authored more than 80 journal papers and presented dozens of invited talks. His high impact papers were published in journals such as Science, Nature Neuroscience, Nature Ecology and Evolution, Science Advances and PNAS.

Prof. Yovel’s research combines biology with technology. His work on bat bio-sonar has driven the development of a bat-like autonomous robot that navigates autonomously using sound only, as well as several other bio-mimetic applications in precision agriculture (two of which were recently patentized). His work on bats drove the development of miniature GPS sensors that allow tracking the smallest animals ever tracked before. His work on bats’ use of bio-sonar for navigation in the field in parallel to using MRI to study the bats’ brain in the lab made him establish a new field which he terms Neuro-Ecology which brings together ideas from Neuroscience and Ecology.

"The geometry of decision-making in collectives and individuals"

Prof. Nir Gov

Department of Chemical and Biological Physics

Rehovot, Israel

Choosing among spatially distributed options is a central challenge for animals, from deciding among alternative potential food sources or refuges to choosing with whom to associate. We present a spin-based model that describes the decision-making process while the animal is moving through space and assessing the different options. Using an integrated theoretical and experimental approach (employing immersive virtual reality), we test the predicted interplay between movement and vectorial integration during decision-making regarding two, or more, options in space.  The theoretical model reveals the occurrence of spontaneous and abrupt “critical” transitions, whereby organisms spontaneously switch from averaging vectorial information to suddenly excluding one among, the remaining options. Experiments with fruit flies, desert locusts, and larval zebrafish reveal that they exhibit these same bifurcations, demonstrating that across taxa there exist fundamental geometric principles that determine how, and why, animals move the way they do.

Phd in theoretical physics at the Technion (low-temperature quantum mechanics) 1998

Postdoc at the U of Illinois Urbana-Champaign, QM

Postdoc in Weizmann, Bio-phys.

PI in weizmann since 2004

My research team and I have been developing theoretical models for various phenomena in biology that involve many interacting units, from the collective migration of cells within a body to collective motion of animals within a group. In addition we study the dynamics of cell shapes, cell migration and general non-equilibrium physics.
