Max Planck Institute for Brain Research

No other organ is as complex as the human brain: each one of its nearly 100 billion nerve cells, or neurons, can connect with thousands of other neurons. And the brain’s “product” – e.g. behavior, action, perception, language, cognition – is extraordinarily varied and still mysterious. The Max Planck Institute for Brain Research is dedicated to the study of brain function on mechanistic and computational levels. The scientific focus of the Institute is on circuits, or networks of interacting parts, including molecules in a neuron, neurons in a local circuit and local circuits in larger brain systems. Scientists at the Institute strive to gain fundamental insights on brain function by studying mainly less complex nervous systems such as those of rodents, turtles or fish. They measure how nervous systems process sensory information, how memories are formed and stored, how circuits are structured, how sleep is produced, how adaptive behaviors are generated, while trying to understand the overarching computational principles governing these processes. The studies apply molecular, imaging, electron-microscopic, genetic, behavioral and electrophysiological methods, as well as numerical simulations and theory.

The Kaiser Wilhelm Institute for Brain Research was founded in Berlin 100 years ago. The first Director was Oskar Vogt, an ambitious scientist who became famous when he investigated Lenin’s brain. His wife Cécile and he provided important findings on the structure of the cerebral cortex – and also labored under a misconception or two.

Our visual ability to separate objects from background depends greatly on detecting local discontinuities of motion, color, contrast or texture. Computing the characteristics of a texture is surprisingly difficult, as confirmed by the hundreds of thousands of trials that neural networks require to “learn” them. Yet our brains segment and differentiate textures without apparent effort. Our research aims to understand how this is done, using cephalopods’s unique ability to camouflage.

Traces of learning in the cerebral cortex

2020 Helmstaedter, Moritz

Neurosciences

The mammalian brain, with its immense number of neurons and extreme density of communication, is the most complex network we know. Methods for partial and sparse analysis of these networks exist for more than a hundred years. However, obtaining locally complete wiring maps of neuronal networks in the mammalian brain only became possible a few years ago. Our research team has now succeeded in mapping brain tissue from the mammalian brain and analyzing it for traces of previous learning processes.

Molecular tracks of learning and memory

2019 tom Dieck, Susanne; Hafner, Anne-Sophie; Donlin-Asp, Paul; Rangaraju, Vidhya; Schuman, Erin

Neurosciences

Although learning and memory are tasks performed by our brain on multiple interconnected levels, we can trace them down to chemical reactions leaving molecular footprints. By visualizing these tiny footprints, we aim to build a molecular model of learning. One important factor seems to be the local production of new proteins near the site of information transfer between nerve cells. We have decoded a logistics principle connecting local protein assembly to increase or decrease of information transfer and clarified questions of energy supply for this process.

The Neocortex represents the largest and most powerful area of the human brain. Having expanded and differentiated the most during mammalian evolution, it mediates many capacities that distinguish humans from their closest relatives. It also plays a central role in many psychiatric disorders. In 2018 our research group has discovered fundamentally new mechanisms that enable neocortex to rapidly and flexibly adjust information processing to the behavioral requirements of the animal.

Can the various functions of the human brain be explained by a single model?

2018 Kraynyukova, Nataliya; Tchumatchenko, Tatjana

Neurosciences

The neural networks in the brain are able to perform calculations such as normalization, information storage and rhythm generation. To date, various mathematical models have been established to imitate these individual calculations. We have used the stabilized supralinear network (SSN) as a basic model and found that it can perform several calculations simultaneously. This indicates the possibility of formulating a unified theory of cortical function.
