Neuroscience Core Course
At the beginning of graduate study in neuroscience, most students have taken at least some neuroscience courses. However, the content of those courses may vary considerably from school to school. Also, neuroscience attracts any students from other disciplines – molecular biology, psychology, physical sciences, computer science, and engineering, to name a few. It is desirable to provide a core course that brings all incoming students to a shared level of competency.
At Princeton, graduate study in neuroscience begins with a two-term core course, NEU 501/502. In conjunction with other prepatory courses (math boot camp, neurophysiology laboratory, Math Tools), NEU 501/502 introduces students to modern neuroscience, with an emphasis on areas where Princeton is strong.
The fall course, NEU 501A, covers molecules, cells, circuits, and small-animal systems neuroscience. Students learn about these subjects through lectures, neuroanatomy laboratory, computational simulations, problem sets, quizzes and exams, and critical reading and writing. By the end, they are ready to begin inquiry into animal systems. They are also prepared for NEU 502A, which covers cognitive neuroscience.
NEU 501A is divided into five parts:
PART 1: BRAIN ORGANIZATION AND ANATOMY
PART 2: MOLECULES, CELLS, AND DEVELOPMENT
PART 3: THE ACTION POTENTIAL, SYNAPTIC TRANSMISSION, RECEPTORS, AND PLASTICITY
PART 4: NEURAL DYNAMICS
PART 5: PHYSIOLOGICAL SYSTEMS AND BEHAVIOR
Instructors include Sam Wang, Sebastian Seung, Michael Graziano, Lisa Boulanger, Asif Ghazanfar, Carlos Brody, David Tank, Jonathan Pillow, Esteban Engel, Lindy McBride, Liz Gould, Annegret Falkner, Mala Murthy, Ilana Witten, Michael Fee, Andy Leifer, and Alan Gelperin.
This intensive introduction to modern neuroscience continues in the spring term with NEU 502. NEU 502 builds on the cellular and circuit mechanisms learned in NEU 501 to understand how the brain gives rise to cognition. The course covers 7 major topics in cognitive neuroscience: sensory systems, long-term memory and sleep, motor control, attention, working memory, cognitive control, and social neuroscience. The class focuses on a circuits/systems understanding of cognition. In particular, there is a strong emphasis on building a computational understanding of cognition (reflecting the computational nature of cognitive neuroscience at Princeton).
Instructors include Tim Buschman, Michael Berry, Carlos Brody, Jon Cohen, Nathaniel Daw, Michael Graziano, Uri Hasson, Mala Murthy, Yael Niv, Ken Norman, Jonathan Pillow, David Tank, Jordan Taylor, Alex Todorov, Sam Wang, and Ilana Witten.
For both 501A and 502A, the course organizer and a teaching assistant attend all lectures.
Intracellular recording and synaptic potentials. The crayfish slow flexor muscle is used as a prep for recording intracellularly, using sharp electrodes, while stimulating afferent fibers. Students go from dissection to studying synaptic potentials.
Short-term synaptic plasticity. Having practiced the crayfish slow flexor muscle prep in lab 1, students now use it to study the difference between facilitation, potentiation, and augmentation in synaptic transmission.
Sensory Coding. Students use recordings from afferent fibers conveying responses to muscle stretch from the crayfish muscle receptor organs to study differing patterns of adaptation and response kinetics in both the tonic and phasic muscle receptors organs in the crayfish abdomen.
2-photon imaging in vivo. Using the immobilized zebrafish larva students carry out calcium imaging of neural activity in the optic tectum during responses to imposed patterns of visual input and subsequently analyze their recordings to quantitatively describe single neuron response patterns to visual patterns.
Directional selectivity in visual interneurons. Using the visual pathway of the blowfly, students record from an identified directionally sensitive interneuron (H1) and quantitatively characterize its responsivity to several features of visual stimuli adequate to activate H1.
Diverse activity patterns in central neurons. The abdominal ganglion of the marine snail Aplysia provides a diverse collection of large central neurons within which intracellular recordings provide quantitative measurements of several basic patterns of intrinsic and synaptically-activated neural activity.
Optogenetic manipulation of fly song production. Using both wildtype and genetically engineered strains of the fruit fly, students record the patterns of male fly song production when critical neurons in the fly song control circuit are manipulated by application of light pulses that activate only neurons expressing a light-sensitive photoprotein.
Computational decision-making dynamics. Students learn to simulate winner-take-all dynamics for decision-making and learn to numerically simulate the dynamical evolution of probability distributions of solutions (Fokker-Planck equations). Students are charged with exploring which biologically-plausible parameter changes in their Fokker-Planck model of 2-alternative-forced-choice decision-making could best explain recent experimental data on muscimol inactivation-induced changes.
"Connectionist" neural networks. Students learn to train multi-layer perceptron (or “backprop”) models, and use them to train these networks in a variety of student-chosen problems.
Measures of functional connectivity: spectral analyses of coherence and Granger causality. Using a dataset from multielectrode, multi-area recordings from monkeys performing a selective attention task, students learn to calculate power and coherence using both autoregressive modeling and modern multi-taper methods, as well as Granger causality spectra. Students analyze these data to determine whether the brain’s attention network in fronto-parietal cortex provides feedback signals to visual cortex to enhance sensory processing.
Models of muscle synergies. Students learn to use, and then compare, modern blind source separation techniques, including principal component analysis, non-negative matrix factorization, factor analysis, and independent component analysis, to study to what extent one can recover muscle synergies given recorded muscle activity.
Mathematical models of memory. Students use an interactive version of the Temporal Context Model of memory recall that allows them to adjust parameters and explore how these parameters affect the model’s predictions, as well as to compare how well these predictions compare to an experimental data set.
Covertly measuring memory retrieval using multi-voxel pattern analysis. Students observe a real-time demonstration of fMRI data collection, and then use pre-collected data from a full memory retrieval experiment to learn how to use modern multivariate pattern classification algorithms.
Cognitive control. Students apply modern dense-scalp EEG recordings in an experiment to assess evidence regarding conflict-related negativity. Students compare their results to existing data and models in the literature.
