Neural Signal Processing 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.
Activity Sensors 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.
Optogenetics By engineering cells with light-responsive ion channels, optogenetics allow the activity of cells such as neurons to become controlled by pulses of visible light. The technology is widely used throughout the institute in experiments in which purposeful instigation or suppression of neural activity can reveal important data on the functions of cells, circuits, systems, and behaviors.
Anxiety Disorders In the brain, neural circuits mediate senses of reward and aversion, memory and behavior. Perturbations in these circuits may result in disease states such as anxiety. By studying the anatomy, function and dynamics of these circuits in regions such as the amygdala, as well as their connections with other regions, Picower scientists are unraveling the bases of these disorders.
