slide3

Starting MATLAB

  • Desktop Demo
  • type demo matlab desktop in the prompt ,and then start a „desktop environment“ demo
slide4

First steps. Learning by doing

  • Matrix Manipulations
slide5

Data analysis

  • Importing Data
  • type demo matlab desktop in the prompt ,and then start a „importing data“
  • Data Analysis Demo
  • Interpolation Demo
slide6

3-D plots

  • Mexican hat function
slide7

Poisson spike train generator

  • Exercise 3

Spike times: ti

Interspike interval distribution: P[τ ≤ ti+1 - ti < τ +Δt] = rΔt exp(rτ).

Formula for generation: ti+1 = ti - ln(xrand)/r.

Relative refractory period:

Autocorrelation function

slide8

Ring neural network model

T

  • Weak coupling with homogeneous input
  • Weak coupling with noisy tuned input
  • Strong coupling with noisy tuned input
  • Strong coupling with nonspecific input
