Welcome to all members! I started my work on EEG data to continuous perediction of cursor movement in flexible way (alpha, mu, beta rhythms) during actual and imagery movements. now I continue my thesis on this approach by EEG data and ECoG data too. I focused on pattern recognition and biosignal processing methods.

Hi It's very nice to join here. I'm working on mainly BCI and some source localization issues. I've made a kind of BCI system to control computer shortly and now am trying to enhance the system as well as find good metod for BCI and signal processing.

I am particularly interested in the structure of EEG signals, the interpretation of EEG oscillations, and in signal processing methods allowing the extraction of EEG time-frequency characteristics. In other words, after dissecting EEG signals I try to search for functionally significant elements within.
I currently involved in a study of the propagation of SSVEP signals using EEG and fMRI, with applications to SSVEP-BCI.

As an epilepsy and pediatric neurosurgeon, I am interested and involved somewhat in BCI. The simplest form of BCI that neurosurgeons use is the Vagus Nerve Stimulator insertion for epilepsy, as I do here at our Neurosciences Center in Riyadh. This device indirectly communicates with the brain through the Vagus nerve to desynchronize and evolving epileptiform discharge. IT is still not very efficacious but it is what's available! it reduces severe intractable epilepsy by an average of 50 to 80 % in 50% of patients only! there are other implantables such as Dr Awan was mentioned for all types of brain malfunctions but many of what is available are still in the stage of infancy and NOT without possible complication... I am more than sure that the future has a lot to offer!

Using Computational Intelligence methodologies for BCI applications is my main interest.

Interestingly, my current as well as the previous hospital that I worked in are both actively involved in research on hippocampal DBS. At the Univ of Toronto, they are studying the effects on memory and neuronogenesis after chronic electrical stimulation of hippocampus in Alzhimer's. The team in Univ of Western Ontario is studying its effects in temporal lobe epilepsy. We did one implantation about two weeks ago. Although I am not directly involved in the projects, as a neurosurgeon I can tell you that surgically it is not a difficult procedure to put an electrode in the hippocampus but whether it has any effect on memory is still a matter of active study. I am trying to get my other colleagues who are doing functional neurosurgery to join this neuro-network. One of them is doing his PhD on hippocampal DBS at Univ of T. His research has shown that chronic stimulation of hippocampus in rodent models does lead to neuronogenesis but whether these are useful neurons and whether they get incorporated into memory circuits etc still remains to be seen.

Hi Nasir Raza Awan and welcome to our group! :)
Even cochlear implantation carry its own risks.
And what about implanting hippocampal protheses into the brain? This structure is deep as can be seen on a picture. Will it be hard, from neurosurgical perspective? Is it more risky than implantations you are doing now?

I am a neurosurgeon doing a fellowship in functional neurosurgery. For big part, functional neurosurgery has come to involve implantation of electrodes in the brain to alter disturbed function, although there are other procedures also that constitute functional neurosurgery.

My main interest is DBS (deep brain stimulation) for psychiatric and behavioral problems.
