Structure of Discussion

Neuroscience (3 weeks):

• Brief recap
• Practice problems

Signal Processing, ML (7 weeks):

• PSets
• Designed to test application of concepts
• Might be helpful for HW problems

Today

• High level overview of course
• Functional regions of the brain
• Basic arch. and func. of neurons

 control signals

Spikes are action potentials, similar to an impulse. So, spike train → impulse train.

Decoder: takes and interprets neural data, turns into motion action

Different types of decoders:

• Decoding neural activity from occipital lobe (vision)
