Definition
Sensory information, percepts, thoughts, and motor commands are thought to be carried out by spatiotemporal patterns of action potentials (spikes) in neuronal populations in the brain. Classical examples of neural encoding are the tuning of V1 neurons to oriented lines and the tuning of MT and M1 neurons to movement direction (Abbott and Dayan 2001). In addition, neural computation is thought to be instantiated by operations on these spatiotemporal spiking patterns. The problem of neural population encoding and decoding is addressed here from the perspective of reading out information about sensory stimuli and behavioral variables from spike trains simultaneously recorded from neuronal ensembles.
Detailed Description
Probabilistic Population Encoding and Decoding
Consider a sensory stimulus or behavioral variable (e.g., hand movement kinematics) x 1:t , during a discrete time period {1, 2,…, t}, x t ∈ ℝp, encoded by the spiking activity y 1:t = {y i1:t ...
