Cogent

The Cogent project was started in 1995. The aim was to develop a computer package that could be used by a novice researcher in the FIL to design experimental stimuli for brain imaging and psychophysical studies. In 1999-2002 this package was completely rewritten as a collaborative project involving the LON, FIL and ICN to provide PC compatibility, with greatly improved visual graphic capability.

Cogent has now been made freely available to the wider scientific community via this web distribution. We do however request that you comply with some simple conditions and that you provide us with some basic details so that we can monitor how Cogent is being distributed. Your details will be covered by the Data Protection Act 1998 and will not be given to any third party.

Cogent is available in two forms:
