Welcome

This site is dedicated to Clinical Neurophysiology.

Updated 12/8/08

A new version of the ATLAS is available which has facilities for displaying a map of the EEG potential field at a given instant and a facility which allows you to obtain an estimated display of the frequency spectrum of a segment of any channel of the displayed page.
These facilities are now fully available on the EEG Atlas which is hosted on the EPTA website (see below)

If you view these records and try the 'Field'or 'Spectrum' facilities please let me know what your experience has been like.

The location of the Atlas will be changing soon. I will update this page and email all users when this happens.

The main ATLAS is presently available on the EPTA website.

This is a collection of clinical EEG records which can be examined and manipulated in detail.

You will need a username and password in order to access the Atlas because it is only available to registered individuals who will generally be Health Care professionals or research workers in relevant fields.
Protection is required for reasons of confidentiality - Patients in general agree for their records to be made available for teaching, but would not necessarily be happy for records to be generally available on the Web.

If you would like to register, please send an email to me hrat@btinternet.com

Please include the following details in your email:-

• A suggested username/password pair.
  Usernames and passwords are case sensitive.
  User names must contain at least 3 characters which may be letters or digits.
  Passwords must contain at least 5 characters at least one of which must be a digit.
• Full name:
• Address:
• Telephone number: (optional)
• Affiliation (e.g. EEG Department, Hospital, University):

If you are a teacher it may be convenient for yourself and all your students to share a single username/password.

An additional example of Web viewing is "EP Display" (This is a display of averaged evoked potentials not an EEG.)

I have also included an illustration The Homeostat from a paper entitled "Chaos in the EEG" which I hope to publish later.
This is included here largely to illustrate the reason why I have decided not to provide a 'scrolling' display of the EEG. At least on my computer the display is too slow and irregular to be of use, except as an animated illustration like the one seen here.
