Biological research often calls for imbuing cells, tissue, or animal models in the lab with specific new capabilities – or disabilities, for instance to observe the differences between altered and unaltered cells. Picower Institute neuroscientists employ advanced techniques such as CRISPR/Cas9, 3D stem cell and printing technologies, and transgenics to conduct such experiments.
In many ways, Picower Institute neuroscientists are explorers for whom new ways to see inside the brain are essential for finding answers to their questions about how the brain works at scales ranging from synapses to whole networks. Researchers at the institute doesn’t just apply the latest imaging techniques, it often creates new technologies to make imaging better.
To understand role of neurons and the circuits in which they participate neuroscientists must be able to gather data on a neuron’s electrical activity, such as when they fire, in real-time. Picower scientists are constantly innovating new genetic and chemical sensors, as well as electronic and imaging-based means to track neural activity both in vitro and in vivo and develop sophisticated means to analyze the large volumes of data gathered.
A typical neuron has thousands of synapses that connect it with other neurons in neural circuits. The location, type and constantly changing strength of each of these synapses determine how each neuron plays its role in the brain and how circuits are remodeled by experience. Research at the Picower Institute to map synapses is therefore essential to understanding how neural connections underlie brain functions and disease.
Fundamentally the central nervous system is made up of cells whose functions are specified by which genes are expressed, and how and when. At the Picower Institute, scientists use “big data” and bio-informatics techniques to make new discoveries about how genes and the proteins that arise from their expression influence brain function and how abnormalities contribute to disease.
Neurons are electrically active, producing patterns of activity that can be observed to understand their function. By developing advanced techniques to detect and analyze these patterns of electrical signals, Picower Institute scientists can advance the study of how brain circuits, for instance for storing and recalling memory, work.
A requirement of learning and memory is a brain capable of stably encoding change. Throughout our lives, in response to our experiences, our neurons form new synaptic connections and prune away others. Scientists in the Picower Institute study these processes of plasticity, elucidating their workings down to the molecule, to better understand how they work.
Perhaps the most prized of our senses, the visual system has long provided neuroscientists a model for studying neural plasticity and development and cortical dynamics. It also is a system in which disorders can produce devastating disabilities. At the Picower Institute, scientists study this system to gain broad insights into the brain and also to address societal needs.
Learning and motivation are often governed by the experience of reward and the desire to obtain it again. At the same time, some diseases such as addiction hijack this system. Researchers at Picower study these systems to gain insight into the mechanisms of healthy and unhealthy behavior.
A hallmark of how our brains work is the interactions of neurons in circuits via dynamically formed connections called synapses. Picower scientists identify, map, and analyze circuits involved in learning and memory, emotion and behavior, and other brain functions both in health and disease.
