|8/27 |Development and history: from single-cell to brain, anatomy and history nervous system, lead into neural development |Swanson |
| |Outline: This lecture deals with the basic plan of the nervous system. Part 1 considers the macrostructural parts of | |
| |the nervous system from a developmental perspective: what is the geography of the nervous system? Part 2 outlines the| |
| |basic cell types of the nervous system from an evolutionary point of view: what is their micro structure- function | |
| |organization? And Part 3 outlines the major functional systems or circuits that together form the vertebrate nervous | |
| |system: how is behavior controlled and how are vital bodily functions coordinated? | |
| |Suggested reading: Swanson, Brain Research Reviews 55:356-372 (2007), and Swanson Trends Neurosci. 23:519-527 (2000).| |

| |Background required: KSJ Chapter 1 | |
|9/1 |Development: Mechanisms of induction, patterning of the nervous system and neurogenesis. |Levitt |
| |Outline: In the first of two lectures, we will determine cover the first stages of neural development, from the | |

| |distinct neuronal identities. | |

| |embryogenesis. We discuss the mechanisms that permit differentiated neurons first to survive and then extend an axon | |
| |to make a highly specific synapse with the relevant target. | |

|9/8 |Basics of Neural Function: Cable Theory |Grzywacz 1 |
| |We will begin by describing neural membranes as equivalent RC-circuit models. The lecture will then sketch the | |
| |development of cable equations for dendrites and axons by considering them as linearly interconnected parallel RC | |
| |circuits. The consequences of the length and time constants, the parameters of the cable equations, will be | |
| |explained. | |
| |Reading: Kandel Chapters 8 and 9; Dayan & Abbott () pp. | |

| |knowledge about their function. The function and basic time course of the action potential. Some understanding of how| |
| |RC circuits work. (Where to Acquire the Background Knowledge: Kandel Chapters 2, 6, and 7.) | |
|9/10 |Basics of Neural Function: Hodgkin-Huxley model |Mel |
| |Building on the previous lecture, we will generalize the RC circuit models to one in which some of the resistors | |
| |(actually, conductances) depend on voltage. We will show how this generalized model, the Hodgkin-Huxley model, | |
| |accounts for the time course of action potentials in neurons. | |
| |Reading: As for the previous lecture. | |
|9/15 |Basics of Neural Function: Synapses, Dendrites and Neural Integration |Grzywacz 2 |
| |This talk will focus on chemical synapses, explaining pre- and postsynaptic mechanisms of the ionotropic and | |
| |metabotropic types. We will also address excitatory and inhibitory synapses, and the NMDA synapse, which is | |
| |important for learning. Finally, we will return to elements of cable theory to explain how dendrites integrate | |
| |postsynaptic activity. | |

| |Background Required: | |
|9/24 |Motor Control: Reach & Grasp |Winstein |
| |In this lecture we see how the motor areas of the cerebral cortex integrate visual, proprioceptive, and other | |
| |information to produce more elaborate voluntary movements that require planning. Our focus will be on the functional | |
| |movements of reach and grasp actions, the role of the fronto-parietal network and how recent advances in fMRI and TMS| |
| |imaging in humans has been harnessed to probe the functional neural networks associated with goal-oriented behaviors | |
| |such as these. I will include a brief mention of mirror neurons in this context, but alert them to the more in depth | |
| |discussion in Arbib’s upcoming lecture (From Motor Control to Cognition). I will organize my lecture around two broad| |
| |questions: | |
| |What is the behavioral evidence that most reach-to-grasp actions are planned in advance? (Rosenbaum et al., | |
| |experiments—I will begin lecture with a simple demonstration of the wine glass experiment). | |
| |What are the functional neural correlates of reach-to-grasp actions? | |

| |Background Required: KSJ Chapter 33 | |
|9/29 |Motor Control: Locomotion and the neural network for swimming. |Bradley |
| |This lecture will review research in animal models and humans that examine the neural control of locomotor system. We| |
| |will consider both the relatively automatic character of locomotor behaviors that are nonetheless continually | |
| |modified to adapt movement to immediate surroundings. We will focus on: | |
| |Regulation of rhythm | |

|10/1 |Motor Control: Theory of motor control (feedback, feedforward & adaptive models) |Schweighofer |
| |Outline: The control of movements can only be performed via feedback or feedforward control. Although feedback | |
| |controllers requires very little neural machinery and allow for error corrections, they are not adequate to generate | |
| |fast and accurate movements in neural systems that contain long conduction and transmission delays; the brain thus | |
| |needs to use feedforward controllers. We present basic concepts of feedback control then discuss how the central | |
| |nervous system learns internal models in feedforward controllers. | |

| |briefly review the connections between the motor cortex and spinal cord. Students will be introduced to the concepts | |

| |describes how decision-making is mediated in the brain, and how neural systems involved in emotional processing play | |
| |a key role in decision-making. I will also describe some applications of this neurological knowledge; specifically | |
