+#### Neo
+
+Neo is a package for representing electrophysiology data in Python,
+together with support for reading a wide range of neurophysiology file formats,
+including Spike2, NeuroExplorer, AlphaOmega, Axon, Blackrock, Plexon, Tdt,
+and support for writing to a subset of these formats, plus non-proprietary formats including HDF5.

 #### PyNN

+PyNN (pronounced 'pine') is a simulator-independent language for building neuronal network models.
+
+In other words, you can write the code for a model once, using the PyNN API
+and the Python programming language, and then run it without modification 
+on any simulator that PyNN supports (currently NEURON, NEST, and Brian),
+and on the SpiNNaker and BrainScaleS neuromorphic hardware systems.
